First we know that:
AB+BC=AC
now , since B is the midpoint of AC, this means that AB=BC
therefore,
AB+BC=AC can also be written as
AB+AB=AC
3x-1+3x-1=8x-20
6x-2=8x-20
-2+20=8x-6x
18=2x
x=9
therefore:
AB=3(9)-1=27-1=26
AC=8(9)-20=52
BC=AB=26
Answer:
8.50(43) + 10.50(6.5)=$433.75
Step-by-step explanation:
You can set these equal to each other. The numerator is how many free throws Shawn makes and the denominator is total free throws. You can cross multiply and solve for x but it’s way easier to just see that 11*2 = 22 and then multiply 7*2 to get x which is 14. Hope this helped!
For f(-2), x will equal -2.
Plug the x-value into the equation:

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

Solve the problem:

f(-2) will equal
1/2.
Answer:
972π m³
Step-by-step explanation:
given
in a sphere
radius (r) = 9 m
Volume (V ) = ?
so we know
The formula for the volume of a sphere is V = 4/3 πr³.
now
V = 4/ 3 * π * 9³
V = 972π m³
hope it helps :)
