Step-by-step explanation:
the circumference of a wheel is one revolution
so
formula: circumference=π*diameter
D=26cm (13*2 to find the whole length from one end to other)
so you'll do 3.14*26 equals 81.64
one revolution=81.64
30 revolutions=2,448.3 inches (times by 30 with 81.64)
Answer:
f(x) + g(x) = (-2x + 8)+ 3x
f(x) + g(x) = -2x + 8 + 3x Combine like terms.
f(x) + g(x) = x + 8
f(x) + g(x) = (f+g)(x) = x + 8
(f + g)(-1) = -1 + 8
(f + g)(-1) = 7
