Answer:

3/π Hz

Step-by-step explanation:

Recall that for a cos function in the form

y = A cos Bx

period = 2π / B

frequency = 1/period = B/2π

Given y = -5 cos 6x

A = -5 and B = 6

frequency,

= B / 2π

= 6 / 2π

= 3/π

An arrow is shot vertically upward at a rate of 280 feet per second. Use the projectile formula
vfiekz [6]

Time is 16.75 seconds when the arrow reaches 200 ft

Step-by-step explanation:

  • Step 1: Find time at height of 200 ft

Height = 200 ft

v = 280 ft/s

Projectile formula, h = -16t² + vt

⇒ 200 = -16t² + 280t

⇒ 16t² - 280t + 200 = 0

⇒ 2t² - 35t + 25 = 0 (dividing by common factor 8)

Using quadratic formula to find t

t = (35 ±√35² - 4×2×25)/2×2

t = (35 ±√1225 - 200)4 = 35 ± 32.02/4

∴ t = 67/4 or 3/4  

t = 16.75 seconds
