Answer:

D

Step-by-step explanation:

1. Find which of these 4 (four) has a y-intercept of positive 4, in this case, B and D. Recall, that the y-intercept means when X is 0 (zero) what is the value of Y?

2. Find the slope of B and D
The formula to find slope is change in y/change in x (Y/X)

B:

X: 0 - 4 = -4
Y: 4 - 0 = 4

4/-4 = -1

D:

X: 0 - -4 = 4

Y: 4 - 0 = 4

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) .

Team A needs to sell 255 bags of popcorn to reach their goal of $100.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Team A will sell the bags of popcorn for $0.50 each.

Team B will sell the cotton candy for $0.75 per stick.

Let the number of bags of popcorn sold by Team A be "x".

So, the total cost for the popcorn machine rental and supplies is

= $15 + 0.05x.

To reach their goal of $100

$100 = 0.5x - ($15 + 0.05x)

$100 = 0.5x - $15 - 0.05x

$115 = 0.45x

x = $115 / 0.45

x = 255 bags of popcorn

Thus, Team A needs to sell 255 bags of popcorn.

Answer:2.12

Step-by-step explanation:

The sizes of the angles are: a = 112, b = 97, c = 85, d = 148

To calculate the sizes of the angles, we substract the given value from 180 (sum of angles on a straight line)

For a = 180 - 68 = 112( sum of angles on a straight line)

      b = 180 - 83 = 97( sum of angles on a straight line)

       c = 180 - 95 = 85( sum of angles on a straight line)

       d = 180 - 32 = 148( sum of angles on a straight line)

Hence, the sizes of the the angles a,b,c,d, are 112,97,85 and 148 respectively

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.

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

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.

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

       (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)

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

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

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.

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:

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.

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.
