A. She would use hours to minutes, which you can do by dividing 22 by 60.
b. 22 / 60 = .366 repeating, or about .37 per minute
Answer:
104
Step-by-step explanation:
you have to find the least common multiple lcm between the bottom numbers. and since there is none before you just multiply the two together to get the same bottom number.
Answer:
Volume of a cube is s×s×s
hence 7 cube=343
343 is the answer. Hope this helps you. Good luck^_^
Answer:
(x + 2)² + 1
Step-by-step explanation:
Given
x² + 4x + 5
To express in vertex form use the method of completing the square
add/ subtract ( half the coefficient of the x- term)² to x² + 4x
= x² + 2(2)x + 4 - 4 + 5
= (x + 2)² + 1 ← in vertex form
Answer:
Please check the explanation.
Step-by-step explanation:
Rebecca's ERROR
Rebecca wrongly used the formula to calculate the average rate of change from x = -1 to x = 3.
She should have used the correct formula to calculate the average rate of change from x = -1 to x = 3 which is:
Average rate = [f(3) - f(-1)] / [3 - (-1)]
But, she reversed the formula.
The correct solution
Considering the graph

Rebecca wants to find the average rate of change from x = -1 to x = 3.
so
at x₁ = -1

at x₂ = 3

Using the formula, we can determine the average rate of change from x = -1 to x = 3
Average rate = [f(3) - f(-1)] / [ x₂ - x₁]
![=\:\frac{\left[9\:-\:\frac{3}{2}\right]}{\left[3-\left(-1\right)\right]}](https://tex.z-dn.net/?f=%3D%5C%3A%5Cfrac%7B%5Cleft%5B9%5C%3A-%5C%3A%5Cfrac%7B3%7D%7B2%7D%5Cright%5D%7D%7B%5Cleft%5B3-%5Cleft%28-1%5Cright%29%5Cright%5D%7D)


Therefore, the average rate of change from x = -1 to x = 3 will be:
Average rate = 15/8
