Answer:
a) f(-1) = 1
b) f(0) = 6
c) f(2) = 8
Step-by-step explanation:
If x is lesser than 0, we have that:
f(x) = 4x + 5
Otherwhise
f(x) = x + 6
(a) f(-1)
Here x = -1.
-1 is lesser than 0
Then
f(x) = 4x + 5
f(-1) = 4*(-1) + 5 = -4 + 5 = 1
(b) f(0)
Here x = 0
When x equals 0
f(x) = x + 6
Then
f(0) = 0 + 6 = 6
(c) f(2)
Here x = 2
When x = 2
f(x) = x + 6
Then
f(2) = 2 + 6 = 8

Step-by-step explanation:
the volume of the cone:
V=3.14*r^2*(h/3)
V=3.14*8*8*(20/3)=200.96*(20/3)=1339.73
Answer:
the weight that attached to the spring is 9.5 inches
Step-by-step explanation:
The computation is shown below:
inches per pound is
= 11 inches ÷ 75 pounds
Now for 65 pounds, it would be
= 11 inches ÷ 75 pounds × 65 pounds
= 9.5 inches
Hence, the weight that attached to the spring is 9.5 inches
