Answer:

A and D

Step-by-step explanation:

Since a (1/3) is less than 1, it is vertically compressed. The -7 is outside of the parenthesis so it is shifting down.

Answer:

options A and D are the correct options.

Step-by-step explanation:

The parent exponential function is f(x) = 2ˣ

Now this function undergoes two transformations to form g(x) = [tex]\frac{1}{3}(2^{x})-7[/tex]

When parent function f(x) = 2ˣ  is multiplied by [tex]\frac{1}{3}[/tex], this means f(x) has been compressed vertically because [tex]\frac{1}{3}[/tex] < 1.

Now we subtract 7 from the new function [tex]\frac{1}{3}[/tex] [tex](2^{x})[/tex], that means we are shifting this function 7 units downwards on y-axis.

Therefore, options A and D are the correct options.

1) What are the zeros of the function?

smaller r: -11, larger r: -14

2) What is the vertex of the parabola

Vertex: (-12.5, 3)

1. Zeros:

The zeros of the function occur when G(r) = 0. So we need to solve the equation:

-(r + 11)(r + 14) = 0

Since the product of two factors is zero when one or both factors are zero, we can set each factor equal to zero and solve for r:

r + 11 = 0 --> r = -11 (smaller r)

r + 14 = 0 --> r = -14 (larger r)

2. Vertex:

The function is given in factored form, which makes finding the vertex a bit easier. The vertex of a parabola in factored form is exactly between the two zeros.

Therefore, the x-coordinate of the vertex is:

(smaller r + larger r) / 2 = (-11 - 14) / 2 = -12.5

To find the y-coordinate (i.e., the function's value at the vertex), we can plug the x-coordinate of the vertex back into the function (G(r)). However, since the function is multiplied by -1, it might be easier to use one of the original zeros (say, r = -11).

G(-11) = -(-11 + 11)(-11 + 14) = 3 (notice how the negative sign cancels out)

[tex]\frac{1}{10000}[/tex]

Step-by-step explanation:

In probability, "AND" means Multiplication

"OR" means addition

There are 100 numbers from 1 to 100. Probability of picking 49 is 1/100 (since we want 1 specific number form 100 numbers).

Question is asking Probability that Phillip selects 49 AND ALSO Shelly select 49. since there is "AND", we just multiply both the probabilities of Phillip and Shelly.

[tex]\frac{1}{100}*\frac{1}{100}=\frac{1}{10000}[/tex]

Answer:

6,3 hope I helped. :) :)

The coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), then let the midpoint be M(x,y) on that line segment. Then, its coordinates are x =(p+m)/2 and y = (q+n)/2.

Given the endpoints of the line segment are A(-3,4) and B(-6,-1), then the coordinates of the midpoint will be,

x = (2+10)/2 = 12/2 = 6

y = (3+3)/2 = 6/2 = 3

Hence, the coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

Answer:

Step-by-step explanation:

3x + 2y = 5

4x − 9y = −5

Multiply the first equation by 4 and the second equation by -3 so we can eliminate x

4(3x + 2y) = 5 *4

Distribute

12x +8y = 20

-3(4x − 9y) = −5*-3

-12x +27y = 15

Add the two new equations together

12x +8y = 20

-12x +27y = 15

------------------------

35y = 35

Divide by 35

35y/35 = 35/35

y=1

Now we can find x

3x+2y =5

3x+2(1) =5

3x +2 =5

Subtract 2 from each side

3x+2-2=5-2

3x=3

Divide by 3

3x/3 = 3/3

Answer:

The correct answer is option B.

Step-by-step explanation:

The given rational expression is:

Factor the numerator and the denominator:

[tex]\frac{x^2-2^2}{x^2+2x+3x+6}[/tex]

Factor the numerator using difference of two squares and the denominator using factorization by grouping.

Step-by-step explanation:

2 > -3     (2 is greater than -3, this is true)

-7 < -5    (-7 is less than -5, this is true because -7 is more negative than -5)

-9 < 1       (-9 is less than 1, this is true)

0 < -4      (0 is less than -4, this is false because 0 is greater than -4)

Among the comparisons given, "0 < -4" is incorrect.

The student is asking which comparison is not correct. After evaluating each comparison, it becomes clear that 0 < -4 is not correct because 0 is not less than -4; in fact, 0 is greater. Other comparisons such as 2 > -3, -7 < -5, and -9 < 1 are all correct, as in each case, the number on the left side of the inequality is indeed larger (or smaller, for negative numbers) than the number on the right side as the symbol indicates.

To understand why 0 < -4 is incorrect, consider the number line where any number to the right is greater than the number to the left. Zero (0) lies to the right of any negative number, including -4, which means it is greater, not less.

Answer:

perimeter = 10x + 2

area = 6x^2 + 2x

perimeter = 52

area = 160

Step-by-step explanation:

perimeter = 2 * length + 2 * width

perimeter = 2(3x + 1) + 2(2x)

perimeter = 6x + 2 + 4x

perimeter = 10x + 2

area = length * width

area = (3x + 1)(2x)

area = (2x)(3x + 1)

area = 6x^2 + 2x

For x = 5:

perimeter = 10x + 2 = 10(5) + 2 = 50 + 2 = 52

area = 6x^2 + 2x = 6(5^2) + 2(5) = 6(25) + 10 = 150 + 10 = 160

The two regular cans of soup has a greater volume than the family size can of soup

Step-by-step explanation:

step 1

Find the volume of two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm

The volume is equal to

[tex]V=2[\pi r^{2} h][/tex]

we have

[tex]r=8/2=4\ cm[/tex] ----> the radius is half the diameter

[tex]h=10\ cm[/tex]

substitute

[tex]V=320\pi\ cm^{3}[/tex]

step 2

Find the volume of one family can of soup, with a diameter of 10 cm and a height of 12 cm

The volume is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=10/2=5\ cm[/tex] ----> the radius is half the diameter

[tex]h=12\ cm[/tex]

substitute

[tex]V=\pi (5)^{2} (12)[/tex]

[tex]V=300\pi\ cm^{3}[/tex]

therefore

Compare the volumes

Answer:

The probability your mean age will be at least 28 is 83%

Step-by-step explanation:

Let X denote the ages of all new employees hired during the last 10 years , then X is normally distributed with;

a mean of 31

a standard deviation of 10.

The sample size obtained is 10 employees. This implies that the sampling distribution of the sample mean will be normal with;

a mean of 31

a standard deviation of [tex]\sqrt{10}[/tex]

The sample mean is a statistic and thus has its own distribution. Its mean is equal to the population mean, 31 and its standard deviation is equal to [tex]\frac{sigma}{\sqrt{n} }[/tex]

where sigma is the population standard deviation, 10 and n the sample size which in this case is 10. [tex]\frac{10}{\sqrt{10} }=\sqrt{10}[/tex]

We are required to find the probability that this sample mean age will be at least 28;

P(sample mean ≥ 28)

Since we know the distribution of the sample mean we simply standardize it to obtain the z-score associated with it;

P(sample mean ≥ 28)

= [tex]P(Z\geq \frac{28-31}{\sqrt{10} } )=P(Z\geq -0.9487)[/tex]

Download song .50

Download album = 4

Let s = number of songs

a = number of albums

She can spend 15 dollars

.5s +4a =15

If she downloads 6 songs, let s=6

.5(6) +4a = 15

3+4a = 15

Subtract 3 from each side

3-3+4a = 15-3

4a = 12

Divide by 4

4a/4 =12/4

a=3

She can buy 3 albums

If she downloads 1 album, let a=1

.5(s) +4(1) = 15

.5s +4=15

Subtract 4 from each side

.5s +4-4=15-4

.5s = 11

Divide by .5

.5s/.5 = 11/.5

s = 22

She can download 22 songs

If she downloads 30 songs, let s=30

.5(30) +4a = 15

15+4a= 15

Subtract 15 from each side

The two fractions with a sum of 2/3 but with neither denominator equal to 3 is,  2/6 +2/6= 4/6 and 4/6 reduced down is 2/3.

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

here, we have,

2/3

= 4/6

=2/6 +2/6

Hence, The two fractions with a sum of 2/3 but with neither denominator equal to 3 is,  2/6 +2/6= 4/6 and 4/6 reduced down is 2/3.

The area of a trapezoid is [tex]\frac{a+b}{2} h[/tex] so substitute the values.

[tex]\frac{14 + 28}{2} 10[/tex] → [tex]\frac{42}{2} 10[/tex] → 21 * 10 → 210mm²

Hope this helps!!

The area of the following trapezoid is 210mm².

The area of a trapezoid can be calculated if the length of its parallel sides and the perpendicular distance (height) between them is given. The formula for the area of a trapezoid is expressed as,

Area = {(a + b) × h} / 2

Where a and b are the parallel sides and h is the height in the figure below.

In the given question we have, a = 14 mm , b = 28 mm and h = 10 mm.

So, by using the formula for finding the area of a trapezoid,

Area = {(14 + 28) × 10} / 2

        = {42 × 10 } / 2

        = 420 / 2

        = 210

The unit of the area is mm².

Therefore, the area of the following trapezoid is 210 mm².
