Answer:
- 7
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
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 = 
= 
= - 7
Answer:
26
Step-by-step explanation:
=15(2) - 2(2)
=30 - 4
=26
Step-by-step explanation:
This is a right triangle with two congruent angles. so this is a isoceles right triangle or called a
45-45-90 triangle. This means that the legs are equal to each other so
Answer:
B= -40
Step-by-step explanation:
So a right triangle has to = 180
So we write the given, which 124+99
we are trying to get 180 so lets subtract that by the equation, 180-124+99
180-(124+99)
12+99=223
180-223
=-43
But in your case it has to be rounded to the nearest tenth
So the answer is -40
2/3 could equal 4/6 , 6/9, 8/12 , 10/15 , 12/18 ETC
