Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11
Given:
The height of a golf ball is represented by the equation:

To find:
The maximum height of of Anna's golf ball.
Solution:
We have,

Differentiate with respect to x.


For critical values,
.




Differentiate y' with respect to x.


Since double derivative is negative, the function is maximum at
.
Substitute
in the given equation to get the maximum height.




Therefore, the maximum height of of Anna's golf ball is 6.25 units.
Answer:
D
Step-by-step explanation:
1/10 is smaller if you think about it as making smaller pieces to get 10 pieces and bigger pieces to make 7 or you can think of it as 1/7 being closer to 0 than 1/10 is. Or you can convert them to decimal 0.14 (1/7) and 0.1 (1/10)
