Write the quadratic function f(x)=-3x^2-3x-46
in the form f(x)=a•(x-h)^2+k

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

First, we need to solve for a common denominator.

A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.

To get the common denominator between [tex]\frac{18}{7}[/tex] and [tex]\frac{5}{6}[/tex], we multiply their denominators.

Now, we know the fractions would look like this:

To solve for the numerators, we can use these equations:

Now, the fractions look like this:

Adding them together:

Now, we can convert this into a mixed number.

Now that we have this, we can subtract that from 6 to get the missing value.

Therefore, the third fraction is [tex]2\frac{25}{42}[/tex].

The equation of the graphed line is expressed as: A. y + 5 = -3/2(x - 4).

The equation that represents a line can be written in point-slope form as y - b = m(x - a), where a point on the line is (a, b) and the slope is m.

Slope (m) = rise/run = -3/2

Substitute a point on the line (a, b) = (4, -5) and m = -3/2 into y - b = m(x - a):

y + 5 = -3/2(x - 4)

The equation is: A. y + 5 = -3/2(x - 4).

Answer:

The answer Is B)  x ≤ −17 or x ≥ 15

Step-by-step explanation:

Answer:

x = 8, y = 15

Step-by-step explanation:

Part (a)

If x and y are inversely proportional, the relationship can be expressed as
[tex]y \propto \dfrac{1}{x}\\\\\rm{(or \;alternatively\;x \propto \dfrac{1}{y})\\\\}\\\\[/tex]

The above relationship [tex]y \propto \dfrac{1}{x}[/tex] can be written as an equation:

[tex]y = \dfrac{k}{x} \codts\cdots(1)[/tex]

where the constant k is known as the constant of proportionality

Part (b)

We know that when x = 12, y = 10

Plugging this into equation (1):

10 = k/12

k/12 = 10

k = 12 x 10

k = 120

So the proportional equation (1) becomes
y = 120/x

We are now given the equation
y = x + 7

Substitute y = 120/x

120/x = x + 7

Subtract 120/x from both sides
0 = x + 7 - 120/x

Multiply by x both sides;
0 = x² + 7x - 120

Or,
x² + 7x - 120 = 0

This is a quadratic equation which we can solve by factoring. There are various techniques. One of them is to find two factors of 120 and see if their sum or difference can be made -7

Factors of 120 are:
[tex]1,\:2,\:3,\:4,\:5,\:6,\:8,\:10,\:12,\:15,\:20,\:24,\:30,\:40,\:60,\:120[/tex]

Take the two factors, a and b that will add or subtract to -7 and multiply to -120

We see that if we choose a = -15 and b = 8

a + b = -7

and

a x b = -120

The solution to the equation is x = 8 or x = -15

Since we are told that both x and y are positive, we can ignore x = -15 and just state that x = 8 is a solution

If x = 8, substitute this in y = x + 7 to get

y = 8 + 7 = 15

This checks with our original proportionality equation:
y = 120/x = 120/8 = 15

Answer
x = 8, y = 15

Step 1: Solve the equation V(t) = 4 for t. To solve the equation V(t) = 4 for t, divide both sides of the equation by 11, which gives us t = 4/11.

Step 2: Interpret the result. The value of t = 4/11 tells us that when the temperature of the water in the cooler is 4/11, the volume of the water is 4.

Therefore, the value of t = 4/11 tells us that when the temperature of the water in the cooler is 4/11, the volume of the water is 4.

Since there are more molecules in larger volumes than smaller ones, the pace of cooling will be slower if the water's volume is increased. Losing the heat energy from all the molecules will therefore take longer.

The question is incomplete and requires further explanation. For the mentioned part, the information is not significant to determine volume of water in the cooler.

Correct answer is: A power model is appropriate because the scatter plot of log angle and log height is roughly linear.

The graphs known as scatter plots show how two variables within a data collection relate to one another. Both a two-dimensional plane and the Cartesian system are used to represent the data points. The Y-axis is used to plot the dependent variable, while the X-axis is used to represent the independent variable or characteristic. Data points are shown on a horizontal and vertical axis using scatter plots in an effort to demonstrate the degree to which one variable is influenced by another.

According to Scatter plot, the relation between log(height) and log(launch angle) is linear.

Let, us consider log(height) = m log(launch angle) + b

Height = [tex]10^{(log(launch angle))}[/tex] + b

Height = [tex](launch angle)^{m}[/tex] + 10ᵇ

Height = (10)ᵇ + [tex](launch angle)^{m}[/tex]

Thus, the relation of height and launch angle is in power mode.

The ratio of the sides are 1:2 and the ratio of the areas is 1:4

Two objects are similar if they have the same shape, or if one has the same shape as the mirror image of the other, this is called similarity.

Since, the side lengths of the triangles are not given, let us consider,

Δ HIJ =

HI = 12, IJ = 14, HJ = 16

And,

Δ EFG =

EF = 24, FG = 28, EG = 32

Therefore, the ratios of the side lengths of Δ HIJ to the corresponding side lengths of Δ EFG are;

HI / EF = 12/24 = 1/2

IJ / FG = 14/28 = 1/2

HJ / EG = 16/32 = 1/2

Since, we get all the ratios equal, therefore, the Δ HIJ is similar to Δ EFG

With a scale factor of 1/2,

The ratio of area is found by squaring the scale factor for length.

Therefore,

ar(Δ HIJ) / ar(Δ EFG) = (1/2)² = 1/4

16.2

Step-by-step explanation:

Find the number in the tenth place 1 and look one place to the right for the rounding digit 5. Round up if this number is greater than or equal to 5 and round down if it is less than 5

Step-by-step explanation:

a regular function finds the functional result y to a given x value.

the inverse function finds the original x to a given y value.

g^-1(1) is therefore the x-value, so that g(x) = 1.

so, we look through the value pairs. where do we find y = 1 ? ah, in the pair (9, 1).

x = 9 lead to the functional result y = 1.

therefore, g^-1(1) = 9

h(x) = y = -3x - 14

in other words, h(x) expresses y in terms of x.

h^-1(x) expresses x in terms of y.

so, we want to transform the functional equation, so that it says "x = ...." :

y = -3x - 14

y + 14 = -3x

x = (y + 14)/-3

and to turn it into regular function notation, we rename x to y and y to x :

y = h^-1(x) = (x + 14)/-3 = (-1/3)(x + 14)

(h○h^-1)(x) = x

always.

in that process we find first what original input value for h lead to the value of x. and then we use that as input value for h. and, of course, we have to get x as result.

to check here in our case

(h○h^-1)(-5) = -5

h^-1(-5) = (-5 + 14)/-3 = 9/-3 = -3

h(-3) = -3×-3 - 14 = 9 - 14 = -5

there you have it.

The asymptotes for the function are:

x = 5 and x = -1.

Option A is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

There are three types of asymptotes.

1) Horizontal asymptotes

2) Vertical asymptotes

3) Oblique asymptotes

Now,

Horizontal asymptotes.

f(x) = 14 / (x - 5)(x + 1)

f(x) = 14/(x² + x - 5x - 5)

f(x) = 14 / (x² - 4x - 5)

The degree of the numerator is less than the denominator.

So,

Horizontal asymptotes.

y = 0

i.e

The x-axis.

Now,

Vertical asymptotes

f(x) = 14 / (x - 5)(x + 1)

Simplify in its lowest term.

Now,

Set the denominator to zero.

So,

(x - 5) ( x + 1) = 0

x - 5 = 0

x = 5

And,

x + 1 = 0

x = -1

Now,

Since there is a horizontal asymptote there are no oblique asymptotes.

Thus,

The asymptotes for the function are:

x = 5 and x = -1.

Answer:

Step-by-step explanation:

Let's call the height of the building "h", and the height of the antenna "a". From the given information, we have:

Angle of elevation to the top of the building = 7°

Angle of elevation to the top of the antenna = 7° + 5° = 12°

We can use tangent to find the height of the building and the height of the antenna. The tangent of an angle is equal to the height divided by the distance, so we have:

tan(7°) = h / 319

And

tan(12°) = (a + h) / 319

We can use the first equation to solve for h:

h = 319 * tan(7°)

And use the second equation to solve for a:

a = 319 * tan(12°) - h

Now that we have expressions for h and a, we can use the tangent function to find the values for h and a. We can use a calculator or look up the values in a table of tangent values.

Rounding the height of the antenna to the nearest 10th of a foot, we find:

a = 319 * tan(12°) - h = approximately 69.9 feet.

To find the total distance Carmen walks, we need to find the distance between each of the four locations: school, park, hobby shop, and home.

The distance between two points (x1, y1) and (x2, y2) in a plane can be calculated using the Pythagorean theorem:

d = √((x2 - x1)² + (y2 - y1)²)

First, let's find the distance between the school and the park:

d = √((-5 - (-5))² + (4 - (-3))²) = √((0)² + (7)²) = √(49) = 7

Next, let's find the distance between the park and the hobby shop:

d = √((3 - (-5))² + (-3 - (-3))²) = √((8)² + (0)²) = √(64) = 8

Then, let's find the distance between the hobby shop and home:

d = √((3 - 3)² + (-3 - 4)²) = √((0)² + (7)²) = √(49) = 7
