Answer:
The average rate of change = 4
Step-by-step explanation:
Given the function
x₁=-2, x₂=4
f(x₁) = f(-2) = 2x²-4 = 2(-2)²-4 = 8-4 = 4
f(x₂) = f(4) = 2x²-4 = 2(4)²-4 = 32-4 = 28
The average rate of change = f(x₂) - f(x₁) / x₂ - x₁
= (28-4)/(4-(-2))
= 24/6
= 4
Thus, the average rate of change = 4
Answer:
3) -11
Step-by-step explanation:
f(-3)=5*(-3)+4
f(-3)=(-15)+4
f(-3)=-11
Answer:
a) He calculated the area, not the circumference. The equation for the area of a circle is πr², while the equation for the circumference is 2πr.
b) He would need at least 3 quarts of paint. 200.96/75≈2.68 He would need that approximately 2.68 quarts of paint, but I suppose the question is asking you the least amount of whole number quarts of paint. The answer for that would then be 3.
The answer is 21.
18 classrooms x 35 students in each classroom = 630 total students
630 total students / 30 students in each classroom = 21
