Solve for xxx. Enter the solutions from least to greatest.Round to two decimal places. (x + 7)^2 - 11 = 0

Answers

Answer 1

The value of x in the equation (x + 7)² - 11 = 0 are x = -7 + √11 and x = -7 - √11

How to solve equations?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

The variable to be solved is x . Variables are numbers represented by letters in an equation.]

Therefore,

(x + 7)² - 11 = 0

(x + 7)(x + 7) - 11 = 0

x² + 7x + 7x + 49 - 11 = 0

x² + 14x + 38 = 0

Therefore, let's factorise the quadratic equation as follows:

x² + 14x + 38 = 0

Using the quadratic formula,

[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

Hence,

a = 1

b = 14

c = 38

Therefore,

x = -7 + √11 and x = -7 - √11

Let u= [-12, 36, 8] and A= [ 5 -2 1 -3 6 1]. Is u in the plane in ℝ3 spanned by the columns of A? Why or why not?
Select the correct choice below and fill in the answer box to complete your choice.
(Type an integer or decimal for each matrix element.)
A.No, the reduced echelon form of the augmented matrix is which is an inconsistent system.
B.Yes, multiplying A by the vector writes u as a linear combination of the columns of A.

Answers

Since n•u is not equal to 0, we conclude that the vector u is not in the plane spanned by the columns of A.

Why plane spanned by the columns of A?

A vector u is in the plane spanned by the columns of a matrix A if and only if the dot product between u and the normal vector of the plane is equal to 0.

In this case, let A = [5 -2 1; -3 6 1]. To determine if u = [-12, 36, 8] is in the plane spanned by the columns of A, we can calculate the dot product between u and the normal vector of the plane, which can be found by taking the cross product of the two columns of A.

Since the cross product of two columns in A gives the normal vector of the plane spanned by the columns, we have:

According to question:

n = (5, -2, 1) × (-3, 6, 1) = (18, -26, -11)

Next, we calculate the dot product of n and u:

n•u = (18, -26, -11) • [-12, 36, 8] = 18 * -12 - 26 * 36 - 11 * 8 = -816 - 936 - 88 = -1840

Since n•u is not equal to 0, we conclude that the vector u is not in the plane spanned by the columns of A. In other words, u is not orthogonal to the normal vector of the plane and therefore, is not in the plane.

What is Area of a figure ?

The quantity of unit squares that cover a closed figure's surface is its area. Square units like cm2 and m2 are used to measure area. A shape's area is a two-dimensional measurement.

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure. The common ways to depict square units, which are the same as areas, are square inches, square feet, etc.

The space around by a shape's perimeter or boundary is known as its area. Using particular mathematical methods, we may determine the area of shape for various geometric forms.

In the shape there is 2 triangles and 3 rectangle

Area of the bottom triangle = 1/2 * 3*4 = 6 sq. units

Area of the top triangle = 1/2 * 4*2 = 4 sq. units

B) Instead of paying off the balance, he makes a payment of $300 and then incurs a finance charge of $24. 66. What is the balance on his account?

Answers

By applying the debt concept, it can be concluded that:

A. He should pay $466.02 to pay off the balance on the account.

B. The balance on his account is $190.68

Debt is an obligation that requires one party, the debtor, to pay money or other agreed-upon value to another party, the creditor.

We have the following information:

Ahmad owes $382.45, and because he owes, it means this value is the debt, and we write it:

D = $382.45

Then he returns two items ($25. 10 & $34. 50) so that their values get credited into his accounts.

D = $382.45 - $25.10 - $34.50 = $322.85

Now after this, he makes another two purchases of $45 and $98.17, which increase his debt and makes:

D = $322.85 + $45 + $98.17 = $466.02

Part A: Since the debt or the account balance is $466.02, then he should pay $466.02 to pay off the balance on the account.

Part B: However, instead of paying off the balance, Ahmed makes a payment of $300 and he has to be charged $24.66. It means that his debt is not paid off:

D = $466.02 - $300 + $24.66 = $190.68

consider the two functions shown below. assume the blue line represents a(x) and the pink line represents b(x). how do the second derivatives of the two functions with respect to x compare?

Answers

The second derivative of a(x) is larger than the second derivative of b(x) for the given x values.

The second derivative of a function with respect to x is the rate of change of the first derivative with respect to x. The second derivative of a function measures the "curvature" of the graph. In the case of the two functions shown, the blue line represents a(x) and the pink line represents b(x). By looking at the graph, we can see that the first derivative of a(x) is steeper than that of b(x). Therefore, the second derivative of a(x) will be larger than the second derivative of b(x). This can be seen by looking at the graph and noting that the blue line has a greater curvature or "bend" than the pink line. In other words, the second derivative of a(x) is larger than the second derivative of b(x) for the given x values.

A distance-time graph, also known as a displacement-time graph or position-time graph, is a graphical representation that shows the relationship between the distance traveled by an object and the time it takes to travel that distance.

Using the information gathered by Georgia's brother, we can plot the points on a coordinate plane to graph the distance the water balloon travelled during a period of 1.5 seconds.

The data points provided are as follows:

Time (s)     Distance (m)

0.25              0.3

0.5                1.2

0.75              2.8

1.0                4.9

1.25              7.7

1.5               11.0

Plotting these points on a graph with time on the x-axis and distance on the y-axis, we get the graph attached.

a sample of 137cs (half-life = 30.1 years) decays at a rate of 10^10 decays per second. how long (in years) will it take the decay rate to decrease to 10^7 decays per second?

Answers

It will take 19.44 years for the decay rate of 137Cs to decrease to 10^7 decays per second.

The decay rate of 137Cs is given by the formula:

A = A0 * e^(-λt)

Where A is the decay rate, A0 is the initial decay rate (10^10 decays per second), λ is the decay constant (ln(2)/30.1 years) and t is the time in years.

To calculate the time, t, required for the decay rate to decrease to 10^7 decays per second, we solve for t and substitute the given values into the equation:

[tex]t = (ln(A0/A))/λ\\t = (ln(10^10/10^7))/(ln(2)/30.1)\\t = 19.44 years[/tex]

The y-intercept of the line y = 2x - 4 is the point (0, -4), which means that the line crosses the y-axis at a point with a y-coordinate of -4.

What is the slope intercept?

The slope indicates the steepness of a line and the intercept indicates the location where it intersects an axis. The slope and the intercept define the linear relationship between two variables and can be used to estimate an average rate of change.

The equation y = 2x - 4 represents a straight line in a coordinate plane.

In this equation, y is the dependent variable and x is the independent variable.

The slope of the line is 2, meaning that the line rises 2 units vertically for every 1 unit it moves horizontally to the right.

The y-intercept is the point where the line crosses the y-axis, and can be found by setting x equal to zero and solving for y.

In this case, when x = 0, y = 2 * 0 - 4 = -4.

Hence, the y-intercept of the line y = 2x - 4 is the point (0, -4), which means that the line crosses the y-axis at a point with a y-coordinate of -4.

The probability of exactly two babies being born deaf is approximately 0.037, or 3.7%.

Calculating Deaf Birth Probability

The probability of exactly two babies being born deaf in a sample of 1,000 babies from healthy baby nurseries can be calculated using the binomial distribution.

The binomial distribution formula for finding the probability of exactly "k" successes in "n" trials with a probability of success "p" is:

        P(X = k) = (n choose k) * (p^k) * ((1-p)^(n-k))

Where "n choose k" is the number of combinations of "n" things taken "k" at a time, and can be calculated as:

       (n choose k) = n! / (k! * (n-k)!)

       For this problem:

       n = 1000 (number of babies surveyed)

       k = 2 (number of deaf babies)

       p = 2/1000 (probability of a baby being deaf in a healthy baby nursery)

Plugging these values into the formula:

P(X = 2) = (1000 choose 2) * (2/1000)² * (998/1000)^998

P(X = 2) = 999000 * 4 * (998/1000)⁹⁹⁸

P(X = 2) = approximately 0.037

So the probability of exactly two babies being born deaf in a sample of 1,000 babies from healthy baby nurseries is approximately 0.037, or 3.7%.

Write the coordinates of the vertices after a rotation *
270° counterclockwise around the origin. P(-8,3) Q(-8,10) R(-4,2)

Answers

The new coordinates for  P(-8,3) Q(-8,10) R(-4,2) are (3,-3) (10,-10) and (2,-2) .

What are coordinates ?

Coordinates can be defined as pair of numbers which are used to determine the position of a given point.

Given

to Write the coordinates of the vertices after a rotation 270° counterclockwise around the origin.

Given points are  P(-8,3) Q(-8,10) R(-4,2) .

we know that if (x,y) are rotated at an  θ, the new coordinates could be ,

x′=xcos(θ)−ysin(θ)   y′=xsin(θ)+ycos(θ).

So,

for p (-8,3)

x' = -8*cos270 - 3 * sin270

x' = 0 + 3

x' = 3

y' = -8*cos270 + 3 * sin270

y' = 0 - 3

y' = -3

(x' , y' ) = (3,-3)

similarly,

for q (-8,10)

x' = -8*cos270 - 10 * sin270

x' = 0 + 10

x' = 10

y' = -8*cos270 +  10* sin270

y' = 0 -10

y' = -10

(x' , y' ) = (10,-10)

similarly,

for q (-4,2)

x' = -4*cos270 - 2 * sin270

x' = 0 + 2

x' = 2

y' = -4*cos270 + 2 * sin270

y' = 0 -2

y' = -2

(x' , y' ) = (2,-2)

Therefore, The new coordinates for  P(-8,3) Q(-8,10) R(-4,2) are (3,-3) (10,-10) and (2,-2) .

A =?

(Use the distributive property to solve, simplify your answers)
PLEASE HELP THIS IS MY LAST QUESTION!!!!!

Answers

3/4(12a+8) =27.6

3/4 Multiplied by () + (multiply by 8) = ()

A = 2.4

How did we get the value?

Expanding the expression inside the parenthesis, we have:

3/4 (12a + 8) = 3/4 * 12a + 3/4 * 8 = 9a + 6

Setting this equal to 27.6 and solving for a:

9a + 6 = 27.6

9a = 21.6

a = 2.4

So, the value of a is 2.4
