Answer:
maximum revenue is 25000
Step-by-step explanation:
The revenue function for a bicycle shop is given by R(x)=x⋅p(x)
Given 

Plug in p(x) in R(x)


Now find out the vertex using formula x=-b/2a
a= -0.4, b=200

Plug in 250 for x in R(x)


So maximum revenue is 25000
Answer:
(1436.8cm³) let me know if that helps
Step-by-step explanation:
-so if the diameter is a straight line and it's 15 cm
-The formula for the sphere it would be v=4/3πr³
-The radius is going to be r=7cm
-v = 4/3 π (7cm)³
-so you would type in 4/3 x 3.14 x 7 ³ =1,436
- 3.14 or π
- you would round it to the nearest 10th (1436.8cm³)
Answer:
x ≈ 10.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° =
=
( multiply both sides by 14 )
14 × cos42° = x , then
x ≈ 10.4 ( to the nearest tenth )
