Trust me its correct

pls mark me as brainliest

Answer:

we conclude that function A has a greater initial value.

Step-by-step explanation:

As we know that the initial value is obtained by setting x=0

so

Given the function A

From function A, it is clear that at point x=0, the value of y=8

i.e.

at x=0, y=8

Given the function B

[tex]y=3x+4[/tex]

substitute the value x=0 to get the initial value of function B

[tex]y=3x+4[/tex]

[tex]y=3(0)+4[/tex]

[tex]y=0+4[/tex]

[tex]y=4[/tex]

i.e.

at x=0, y=4

Therefore, we conclude that function A has a greater initial value.

The algebraic expression of the statement is 16c

The statement is given as:

the product of 16 and the number of chipmunks

Product means *

So, we have:

16 * the number of chipmunks

The number of chipmunks is represented with c

So, we have

16 * c

Evaluate

16c

Hence, the algebraic expression of the statement is 16c

Answer:

B. The function shown on the graph has a smaller rate of change and a lower starting point.

Step-by-step explanation:

✍️The function y = 6x - 1, has:

slope (m) = 6, and

Starting point/y-intercept (b) = -1

✍️Let's find the slope (m) and the starting point (y-intercept) of the function shown on the graph:

Using the points, (0, -6) and (2, 4),

Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -(-6)}{2 - 0} = \frac{10}{2} = 5 [/tex]

Slope (m) = 5

The strating value is the value of y when x = 0. In order words, it is the point at which the line of the function intercepts the y-axis.

The y-axis is intercepted at y = -6.

Therefore, the starting value (b) = -6.

Therefore, the statement correctly compares the function shown on the graph above with the function y = 6x - 1 is:

B. The function shown on the graph has a smaller rate of change and a lower starting point.

Comparing their slopes, 5 is smaller than 6.

Comparing their starting points, -6 is lower than -1.

B

The probability of getting 3 in 132 times is 22.

A probability is a number that reflects the chance or likelihood that a particular event will occur.

Given that, Paul rolls a fair dice 132 times.

The probability of getting 3 in one roll is 1/6

so now it is 132 rolls

so,

= 132/6

= 22

Hence, The probability of getting 3 in 132 times is 22

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 5, - 1 ] , thus

f(b) = f(- 1) = - (- 1)² - 4(- 1) + 6 = - 1 + 4 + 6 = 9

f(a) = f(- 5) = - (- 5)² - 4(- 5) + 6 = - 25 + 20 + 6 = 1 , then

average rate of change = [tex]\frac{9-1}{- 1-(-5)}[/tex] = [tex]\frac{8}{4}[/tex] = 2

Answer: [-4, 8]

Step-by-step explanation:

The range is the mimimum y-value, the highest y-value.

On the graph, the lowest y-value is -4 and the highest y-value is 8. Thus, when writing in the range form, the range would by [-4, 8].

The range would be in hard brackets because the range touches exactly the points of -4 and 8. If each point had an open circle, instead of a closed point, there would be soft brackets.

Answer:

See Explanation

Step-by-step explanation:

The options are missing. However, the question is still solvable.

Given

[tex]Work\ Hours = 1944[/tex]

[tex]Earnings = \$14[/tex] per hour

[tex]Estimated\ Earnings = \$28,000[/tex]

[tex]Sedan = \$25,750[/tex]

[tex]Convertible = \$27,990[/tex]

[tex]SUV = \$29,500[/tex]

First, we need to calculate her actual earnings.

This is calculated by multiplying the actual work hours (without approximation) by the earnings per hour

[tex]Total\ Earnings = 1944 * \$14[/tex]

[tex]Total\ Earnings = \$27,216[/tex]

Next, we compare this actual earnings to the amount of a Convertible

[tex]\$27216 < \$27,990[/tex]

Hence, Ashlee's conclusion is not logical because with her actual earnings, she cannot afford a Convertible

Step-by-step explanation:

 Elevation of the road at 5 miles from the starting point is 1250 ft.

Given in the question,

Two triangles formed by a road are ΔADE and ΔABC (As shown in the figure attached).

Since, ∠A ≅ ∠A (Reflexive property)

           ∠AED ≅ ∠ACB (right angles)

            ΔADE ~ ΔABC (By A-A property of similarity)

In these similar triangles, corresponding sides will be proportional.

[tex]\frac{AB}{BC}=\frac{AD}{DE}[/tex]

[tex]\frac{8}{2000}=\frac{5}{DE}[/tex]

[tex]DE=\frac{5\times 2000}{8}[/tex]

      [tex]=1250[/tex] miles

   Therefore, elevation of the road at 5 miles from the starting point will  be 1250 ft.

    Option (B) will be the answer.
