Help please- 20 Points A certain Ferris wheel is turning counterclockwise. At a particular instant, a rider is moving horizontally to the right at 2.5 feet per second and vertically up at 6 feet per second.
How fast is the rider actually moving?

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

answer is c

step-by-step explanation:

81/12=324/x

x=48

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
