Answer:
Step-by-step explanation:
A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form
.
If our equation is , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.
Answer:
C. 570.20 ft²
Step-by-step explanation:
Surface
A = 2·pi·r^2 + 2·pi·r·h
A = 2·pi·5.5^2 + 2·pi·5.5·11 = 570.20 ft²
