In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument.
Answer:
C. 40π cm²
Explanation:
• The central angle of the sector = 225 degrees
,
• The radius of the sector = 8cm
For a sector of radius r and central angle θ, we calculate the area using the formula below:

Substituting the given values, we have:

The area of the sector is 40π cm².
Answer:
f(-5)=-5
Step-by-step explanation:
f(-5)= -((-2)(-5)-5)
= -(10-5)
= -(5)
= -5
Step-by-step explanation:
g(x)=3x+5
g(-3)=3(-3)+5
=-9+5
=-4
