Answer:
f(4) for the function
is 
Step-by-step explanation:
We need to find f(4) for the function 
For finding f(4) we will put x= 4 in the given function

Put x = 4

SO, f(4) for the function
is 
Answer:
The height of the cone is 0.5
Step-by-step explanation:
The formula of a cone is:
V= 1/3 πr² h
where r = 4 inches
V = 8 cubic inches
Now plug the values in the formula:
8 = 1/3 * 3.14 *(4)^2 *h
8 = 1/3 * 3.14 * 16 *h
8 = 50.24/3 * h
Now shift the R.H.S to the L.H.S
8 * 3/50.24 =h
24/50.24 = h
0.477707 =h
Rounding off to the nearest tenths place
=0.48
=0.5
Thus the height of the cone is 0.5 ...
Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The parabola vertex point is always (h, k) in y = (x-h)^2 + k
All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
Answer: $440
Step-by-step explanation:
80*5 = 400
10% of 400 = 40
400 + 40 = 440
Ans. $440
