Someone please help me out!!! A sinusoidal function repeats itself every 40 seconds, has a maximum
height of 10 m, and a minimum height of 6 m. At time t=0, the function's
height is at its maximum value. *
A) f(x) = 2 sin(9x) + 6
B) f(x) = 2 sin(9x) + 8
C) f(x) = 2 cos(9x) + 8
D) f(x) = 2 cos(9x) + 6

step-by-step :

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
