Answer:

Step-by-step explanation:

Since Ms. Snow had all her students that were present participate in the survey the number of how many x is the number of students that were present. The number of x is 24, so 24 students were present that day. Since two students were absent add 2 to 24, which is 26 and the number of students enrolled in the class.

present (took the survey) + absent = total enrolled

24 + 2 = 26

Please help, will grant brainliest if correct, need now!!
Mama L [17]

Answer:

- 7

Step-by-step explanation:

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

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ - 5, - 2 ]

f(b) = f(- 2) = (- 2)² - 4 = 4 - 4 = 0

f(a) = f(- 5) = (- 5)² - 4 = 25 - 4 = 21, thus

average rate of change = \frac{0-21}{-2-(-5)} = \frac{-21}{3} = - 7

finlep [7]

Answer:

The area of the copper circle is <u>31.4 inches</u>.

Step-by-step explanation:

Given:

An artist used silver wire to make a square that has a perimeter of 40 inches.

She then used copper wire to make the largest circle that could fit in the square, with perimeter of 40 inches.

Use 3.14 to represent π.

Now, to find the area of the copper circle.

Perimeter of square = 40 inches.

So, we get the side of square by putting formula:

Perimeter=4\times side

40=4\times side

Dividing both sides by 4 we get:

10=side.

Side=10\ inches.

Now, as the side of square is 10 inches it is the diameter of the circle as the square is fit inside the circle:

For getting the area of circle we find the radius:

Radius (r) = \frac{Diameter}{2} \\=\frac{10}{2}= 5\ inches.

Now, putting the formula to get the area of the circle:

Area=2\times \pi \times r

Area=2\times 3.14\times 5

Area=31.4\ inches.

Therefore, the area of the copper circle is 31.4 inches.
