Answers

Answer 1

Answer:

The average rate of change of f(x) over the interval -1 ≤ x ≤ 1 is -1.

Given the function $f(x) = x^2 - x - 1$ over the interval -1 ≤ x ≤ 1, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the x-values.

The value of f(x) at the endpoint x = -1:

f(-1) = (-1)² - (-1) - 1 = 1 + 1 - 1 = 1

Now, the value of f(x) at the endpoint x = 1:

f(1) = (1)² - (1) - 1 = 1 - 1 - 1 = -1

The difference in the function values is:

f(1) - f(-1) = -1 - 1 = -2

The difference in the x-values is:

1 - (-1) = 2

Now, we can calculate the average rate of change:

Average rate of change = (f(1) - f(-1)) / (1 - (-1)) = -2 / 2 = -1

Therefore, the average rate of change of f(x) over the interval -1 ≤ x ≤ 1 is -1.

Eighty percent of seniors at the local high school graduate each year. If there are 750 seniors this year, how many will graduate?670
650
600
500

Answers

What you need to find is 80% of 750

There are many ways to figure that out but the way that I did it is to divide 750 by 100. The answer (7.5). Is 1% of 750
In all I had to do was multiply 7.5 x 80. Giving us the answer which is 600

Anna wants to celebrate her birthday by eating pizza with her friends. For \$42.50$42.50dollar sign, 42, point, 50 total, they can buy ppp boxes of pizza. Each box of pizza costs \$8.50$8.50dollar sign, 8, point, 50.

Answers

Answer: 5

Step-by-step explanation:

From the question, Anna has an amount of $42.50 to pay for pizza and each pizza costs $8.50. She wants to buy an unknown number of pizzas, that we are representing by p.

P= Total amount Anna has/cost of each pizza

P = $42.50/$8.50

P = 5

Anna can buy 5 pizzas

What is the square root of 141?

Answers

The square root of 141 = $√(141)$

This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.

If you want it simplified (like with a calculator) it would be:
$√(141) =11.87$

The square root of 141
√141=11.87434208703792
