Answer:
13a² - 39a + 46
Step-by-step explanation:
To find g(a-2)+3g(2a), find each part using the function g(x)=x²-5x+8.
g(a-2) = (a-2)²-5(a-2)+8 = a² - 4a + 4-5a + 10+8 = a² - 9a + 22
3g(2a) = 3{(2a)²-5(2a)+8} = 3{ 4a² - 10a + 8} = 12a² - 30a + 24
Combine the values to find g(a-2)+3g(2a).
g(a-2)+3g(2a) = (a² - 9a + 22) + (12a² - 30a + 24) = 13a² - 39a + 46
Volume formula for a cylinder is pi*r^2*h
h=height=25 feet
r=radius=101.5
Radius is half of the diameter.
Plug those numbers in: pi*101.5^2*25= 809136.822886= 8.09*10^5 hopefully this helps! ^-^
Answer:
50
Step-by-step explanation:
Answer:
a
b
c
Step-by-step explanation:
The number of vehicles available is 
The number of vans is k = 5
The number of cars is n = 13
Generally P(E) is mathematically represented as
=> 
=>
Generally P(F| E) means the probability that the second vehicle assigned is a van given that the first one selected is a van this mathematically calculated as
Generally 
is also mathematically represented as
=> 
=> 
=>
The equation for finding volume of a cylinder is V=πr2h. That means if you do (3.14)(25)(17) you would get your answer- 1334.5
