By finding the derivative and evaluating it in x = -2, we will see that the slope is 12.

How to find the slope of the function at the given point?

To find the slope of the tangent line at a given point, we need to take the derivative and evaluate it in the x-value of the given point.

Here we have the function:

f(x) = 3x² + 7

If we differentiate it with respect to x, we will get:

f'(x) = 2·3x

f'(x) = 6x

That is the derivative, now we want to find the slope at (-2, 19), to find the slope at that point we need to get:

f'(-2) = 6·-2

f'(-2) = -12

That is the slope of the graph.

Uri paid a landscaping company to mow his lawn. The company charged $74 for the service plus
5% tax. After tax, Uri also included a 10% tip with his payment. How much did he pay in all?

Answers

Uri paid a total of $85.47 for the landscaping service including tax and tip.

What is tax?

Taxes are compulsory payments made by a government organisation, whether local, regional, or federal, to people or businesses. Tax revenues are used to fund a variety of government initiatives, such as Social Security and Medicare as well as public infrastructure and services like roads and schools. Taxes are borne by whoever bears the cost of the tax in economics, whether this is the entity being taxed, such as a business, or the final users of the items produced by the firm. Taxes should be taken into consideration from an accounting standpoint, including payroll taxes, federal and state income taxes, and sales taxes.

Given that company charged $74 for the service plus 5% tax.

The tax is 5%, that is:

Tax = 5% of $74 = 0.05 x $74 = $3.70

Cost after tax = $74 + $3.70 = $77.70

Now, tip is 10%:

Tip = 10% of $77.70 = 0.10 x $77.70 = $7.77

Total cost = $77.70 + $7.77 = $85.47

Hence, Uri paid a total of $85.47 for the landscaping service including tax and tip.

Solve the polynomial equation by factoring and then using the zero-product principle.

Rewrite the equation in factored form.
(Blank)= 0

What is the solution pair?

Answers

the factored form of the equation is 2(13x - 2) = 0, and the solution to the equation is x = 2/13.

Why it is and what is Zero-Product formula?

First, we can simplify the equation by combining like terms:

28x - 4 = 2x - x

Simplifying further:

26x - 4 = 0

Now, we can factor out 2 from the left side of the equation:

2(13x - 2) = 0

Using the zero-product principle, we can set each factor equal to zero:

2 = 0 or 13x - 2 = 0

The first equation is impossible since 2 is not equal to zero. Solving the second equation, we get:

13x - 2 = 0

Adding 2 to both sides:

13x = 2

Dividing both sides by 13:

x = 2/13

Therefore, the factored form of the equation is 2(13x - 2) = 0, and the solution to the equation is x = 2/13.

The zero-product property or formula states that if the product of two factors is zero, then at least one of the factors must be zero. In other words, if a and b are real numbers such that ab = 0, then either a = 0, b = 0, or both a and b are zero. This property is often used to solve polynomial equations by factoring the expression and then setting each factor equal to zero.

Estimate a 15% tip on a dinner bill of $58.12 by first rounding the bill amount to the nearest ten dollars.

Answers

Answer: an estimated 15% tip on a dinner bill of $58.12 would be $8.72.

Step-by-step explanation:

First, we can calculate 10% of $58.12 by moving the decimal point one place to the left, which gives us $5.81.

Then, we can calculate half of 10%, which is 5%, by dividing $5.81 by 2, giving us $2.91.

Finally, we add 10% and 5% to get the estimated tip amount:

$5.81 + $2.91 = $8.72

Therefore, an estimated 15% tip on a dinner bill of $58.12 would be $8.72.

What is a circle?

A circle is a two-dimensional geometric figure that consists of all the points in a plane that are equidistant from a given point called the center. The distance from the center to any point on the circle is called the radius, which is denoted by the letter "r".

To find the cardinality of n(A∩B∩C^c), we need to know the number of elements that are in the intersection of A and B but not in C.

One way to approach this is to use the principle of inclusion and exclusion. This states that:

n(A ∪ B ∪ C) = n(A) + n(B) + n(C) - n(A ∩ B) - n(A ∩ C) - n(B ∩ C) + n(A ∩ B ∩ C)

We can rearrange this formula to solve for n(A ∩ B ∩ C^c):

n(A ∩ B ∩ C^c) = n(A ∩ B) - n(A ∩ B ∩ C) - n(B ∩ C) + n(A ∩ C) + n(B) + n(C) - n(A)

Plugging in the values we have been given, we get:

n(A ∩ B ∩ C^c) = 4 - 3 - 9 + 7 + 11 + 15 - 10

Simplifying this expression, we get:

n(A ∩ B ∩ C^c) = 15

Therefore, there are 15 elements in the intersection of sets A and B but not in set C.

2. Urn A contains 4 black, 3 red, and 3 white balls, whereas urn B contains 3 white, I red, and 3 black balls. A ball is drawn at random from urn A and placed in urn B. A ball is then drawn from urn B. It happens to be red. What is the probability that the ball transferred was red?

Answers

The probability that the ball transferred was red, given that a red ball was drawn from urn B, is 21/55, or about 0.382.

What is probability ?
Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 means that the event is impossible, and 1 means that the event is certain to happen.

To calculate probability, we usually take the number of favorable outcomes and divide it by the total number of possible outcomes. For example, if we flip a coin, the probability of getting heads is 1/2 because there is only one favorable outcome (heads) out of two possible outcomes (heads or tails).

According to the question:
Let's use Bayes' theorem to find the probability that the ball transferred was red:

Let R be the event that a red ball is drawn from urn B, and T be the event that the transferred ball was red.

Then we want to find P(T = red | R = red).

By Bayes' theorem, we have:

P(T = red | R = red) = P(R = red | T = red) * P(T = red) / P(R = red)

We can calculate each of these probabilities as follows:

P(R = red | T = red): The probability of drawing a red ball from urn B, given that a red ball was transferred from urn A to urn B, is 1/4, since urn B originally contained 1 red ball out of 7 total balls (3 black, 3 white, and 1 red) and we added one more red ball to it.

P(T = red): The probability that a red ball was transferred from urn A to urn B is 3/10, since urn A originally contained 3 red balls out of 10 total balls and we transferred one ball at random.

P(R = red): The overall probability of drawing a red ball from urn B is:

P(R = red) = P(R = red | T = black) * P(T = black) + P(R = red | T = red) * P(T = red)

where T = black means that a black ball was transferred from urn A to urn B. We can calculate each of these conditional probabilities as follows:

P(R = red | T = black): The probability of drawing a red ball from urn B, given that a black ball was transferred from urn A to urn B, is 1/7, since urn B originally contained 1 red ball out of 7 total balls (3 black, 3 white, and 1 red) and we did not add any more red balls to it.

P(T = black): The probability that a black ball was transferred from urn A to urn B is 4/10, since urn A originally contained 4 black balls out of 10 total balls and we transferred one ball at random.

Therefore, we have:

P(R = red) = 1/7 * 4/10 + 1/4 * 3/10 = 1/35 + 3/40 = 11/140

Putting it all together:

P(T = red | R = red) = (1/4) * (3/10) / (11/140) = 21/55

So the probability that the ball transferred was red, given that a red ball was drawn from urn B, is 21/55, or about 0.382.

Answers

The slope of the graph f(x) = 3x² + 7 at (-2, 19) is -12

What is the slope of a graph?

The slope of a graph is the derivative of the graph at that point.

Since we have tha graph f(x) = 3x² + 7 and we want to find its slope at the point (-2, 19).

To find the slope of the graph, we differentiate with respect to x, since the derivative is the value of the slope at the point.

So,  f(x) = 3x² + 7

Differentiating with respect to x,we have

df(x)/dx = d(3x² + 7)/dx

= d3x²/dx + d7/dx

= 6x + 0

= 6x

dy/dx = f'(x) = 6x

At (-2, 19), we have x = -2.

So, the slope f'(x) = 6x

f'(-2) = 6(-2)

= -12

So, the slope is -12.

Find the surface area of the triangular pyramid. The side lengths of the base are equal.

Answers

The surface area of the triangular pyramid is the sum of the lateral surface area and the base area.

Lateral Surface Area: The lateral surface area of a triangular pyramid is equal to the product of the slant height and the perimeter of the base.

Slant height = √ ( (length of side)2 + (height)2 )

Perimeter of the base = 3 x length of side

Therefore, the lateral surface area = √ ( (length of side)2 + (height)2 ) x 3 x length of side

Base Area: The base area of the triangular pyramid is equal to one-half of the product of the three side lengths.

Therefore, the base area = 1/2 x (length of side) x (length of side) x (length of side)

Surface Area: The total surface area of the triangular pyramid = lateral surface area + base area

Therefore, the surface area = √ ( (length of side)2 + (height)2 ) x 3 x length of side + 1/2 x (length of side) x (length of side) x (length of side)

Answers

For the given CDF of X, the pmf of X at 1,3,4,6 and 12 is written as :

P(X = k) = 0.30 for k = 1 , P(X = k) = 0.10 for k = 3,

P(X = k) = 0.05 for k = 4 , P(X = k) = 0.15 for k = 6,

P(X = k) = 0.40 for k = 12.

In order to find the probability mass function (PMF) of X, we need to calculate the probability that X takes on each possible value.

Since X can take on any positive integer value, we can start by calculating the probability that X equals each positive integer.

⇒ P(X = 1) = 0.30,

⇒ P(X = 3) = F(3) - F(1) = 0.40 - 0.30 = 0.10

⇒ P(X = 4) = F(4) - F(3) = 0.45 - 0.40 = 0.05

⇒ P(X = 6) = F(6) - F(4) = 0.60 - 0.45 = 0.15

⇒ P(X = 12) = F(12) - F(6) = 1 - 0.60 = 0.40

Therefore, the required PMF of X is: P(X = 1) = 0.30 , P(X = 3) = 0.10 , P(X = 4) = 0.05 , P(X = 6) = 0.15 and P(X = 12) = 0.40 .

Cells ire approximately round with a diameters ranging from 1 to >100 micrometers. The graph below shows the cross section of half a cell with a diameter of 2μm. The curvature of the cell surface determines if and how vesicles can form. Find the curvature of the cell surface y at the red point x=0.25 from the equation for a circle: y= (2−x)x

Answers

The curvature of the cell surface that has a shape of circle y at the red point x=0.25 is 1.75.

What is diameter?

Diameter is a line segment that passes through the center of a circle or sphere and has its endpoints on the circumference of the circle or sphere. The diameter of a circle is twice the length of its radius, so if the radius is given, the diameter can be calculated by multiplying the radius by two.

The equation is given as y = (2 - x)2, where x is the distance from the centre of the circle and y is the curvature of the circle at that distance. To calculate the curvature of the cell surface at any given point, the distance from the centre needs to be known. In this example, the distance from the centre is 0.25, and the curvature of the cell surface at this point is 1.75.

A low curvature, such as 1.75, will allow for more vesicles to form on the surface of the cell. A low curvature will allow for more vesicles to form, and a high curvature will prevent the formation of vesicles.

The equation for a circle with a diameter of 2μm is given as y = (2 - x)2. Substituting x = 0.25 into the equation yields y = (2 - 0.25)2 = 1.75.

What is diameter?

A circle or sphere's diameter is defined as a line segment with its endpoints on the circumference and that travels through the middle of the object. If the radius is known, the diameter can be determined by multiplying the radius by two since the diameter of a circle is twice the length of its radius.

It is possible to compute the cell surface's curvature at x = 0.25 as follows:

Let's look at the circle's calculation.

y = √(2 - x)x

Now, when x = 0.25,

y = √(2 - 0.25)×0.25

y = √1.75×0.25

y = 0.66

What if the equation of the line that passes through (-4,5) and is parallel to the line 4x+2y=10

Answers

Answer: y = -2x -3

Step by step explanation

First, we find the gradient of the line 4x + 2y = 10 by making y the subject of the formula.

4x + 2y = 10

2y = 10 - 4x which is the same as 2y = -4x + 10

Divide each term by 2

2y/2 = -4x/2 + 10/2

y = -2x + 5

From the equation, the gradient (coefficient of x) is -2

Since the line is parallel to 4x+2y=10, therefore the gradient of the lines are the same

The equation of the line can be gotten from y - y1 = m(x -x1)

where y1 = 5, x1 = -4 and m = -2

Therefore subtitiuiting into y - y1 = m(x -x1)

y - 5 = -2(x-(-4))

y - 5 = -2(x + 4)

y - 5 = -2x - 8

y = -2x -8 + 5

y = -2x -3

you can see that the gradients are the same (coefficent of x = -2)

Answer: D. Square

Step-by-step explanation:

The shape created by the cross section of the cut through a square pyramid is a square.

To see why, imagine the pyramid sitting on a table with its square base flat against the surface. The cut goes through the vertex, which is the point at the top of the pyramid. Since the cut is perpendicular to the base, it divides the pyramid into two smaller pyramids with congruent, but not identical, bases. Each of these smaller pyramids has a triangular base that is an isosceles right triangle. The two triangles share a common hypotenuse, which is the line of the cut.

The cross section of the cut is the shape formed where the two triangles meet along the hypotenuse. Since both triangles are congruent and the hypotenuse is the same for both, the cross section is a square. The sides of the square are equal to the base of the original pyramid, which is one of the legs of the isosceles right triangles formed by the cut. Therefore, the answer is D, a square.

A water cooler springs a leak and empties in 2 minutes. The graph below shows the rate at which water leaks from the cooler as a function of time.

Answers

The amount of water that was in the cooler before it started leaking was 6 gallons.

Describe Integration?

Integration is a mathematical process that involves finding the integral of a function. It is the reverse operation of differentiation, which involves finding the derivative of a function. The integral of a function is a measure of the area under the curve of the function, between two given limits of integration.

The graph shows the rate at which water leaks from the cooler as a function of time, which means that the y-axis represents the rate of leakage in gallons per minute (gal/min), and the x-axis represents the time in minutes.

Since we know that the cooler emptied in 2 minutes, we can integrate the leakage rate over the time interval [0, 2] to find the total amount of water that leaked out:

Total amount of water leaked = ∫[0,2] leakage rate(t) dt

The leakage rate is given by the graph, which consists of a straight line connecting two points: (0,6) and (2,0). We can express this line as a linear equation in slope-intercept form:

leakage rate(t) = mt + b

where m is the slope of the line and b is the y-intercept. To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0,6) and (x2, y2) = (2,0). Plugging in the values, we get:

m = (0 - 6) / (2 - 0) = -3

So the equation of the line is:

leakage rate(t) = -3t + 6

Now we can integrate this equation over the time interval [0, 2] to get the total amount of water leaked:

Total amount of water leaked = ∫[0,2] (-3t + 6) dt

= [-3t²/2 + 6t] from 0 to 2

= (-3(2)²/2 + 6(2)) - (-3(0)²/2 + 6(0))

= (6 - 0) - (0 - 0)

= 6 gallons

Therefore, the amount of water that was in the cooler before it started leaking was 6 gallons.

The conditional relative frequency that a student rides the bus, given that the student is in middle school is 0.16 / 0.96 ≈ 0.17.

Describe conditional relative frequency ?

Conditional relative frequency is a statistical measure that describes the proportion or percentage of a specific group or category within a subset of data. It is calculated by dividing the frequency of the specific category in the subset by the frequency of the total subset.

To find the conditional relative frequency that a student rides the bus, given that the student is in middle school, we need to divide the frequency of middle school students who ride the bus by the total number of middle school students.

From the table, we see that the frequency of middle school students who ride the bus is 0.16. The total number of middle school students is the sum of the frequencies in the first row, which is 0.20 + 0.16 + 0.12 + 0.48 = 0.96.

So, the conditional relative frequency that a student rides the bus, given that the student is in middle school is:

0.16 / 0.96 ≈ 0.17

Rounded to the nearest hundredth, the answer is 0.17. Therefore, about 17% of middle school students ride the bus.
