Which statement is true about the circumference of a circle?
The circumference is equal to the radius of the circle.
The circumference is equal to the diameter of the circle.
The circumference is found by multiplying x by the radius.
The circumference is found by multiplying x by the diameter.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

i belive those are the ones that are under 90 degreese.
