-45x+72
you multiply the 9 by everything in the parentheses
When we have a function such as h(x) = 2x, and we want to find the value of h at a given x value, we plug in the given number for x. For example, h(3) = 2*3 = 6.
We do the same thing with g(f(7)). In this case we plug 7 into f(x) for x, then plug the result of f(7) into g(x) for x.
f(7) = 15*7 - 12 = 93
g(93) = -15*93^2 + 14*93 - 10 = -128443
180/7=25.71428571 per hour
25.71428571/60=0.428571428 (per second
0.428571428/60=0.007142857 (per minute) miles
in foot it is 0.000595238
425.69+298.72=724.41
29.72+135.47+208.28=373.47
724.41-373.47=350.94
350.94-5=345.94
The answer is c
Answer:
35 cm
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 1058.75π
Divide both sides by π.
r²h = 1058.75 cm³
r = 5.5 cm
Substitute r² with (5.5 cm)².
(5.5 cm)²h = 1058.75 cm³
h = 1058.75/30.25 cm
h = 35 cm
