A searchlight rotates through one complete revolution every 52 seconds how long does it take to rotate 90 degrees?

Time taken to rotate 90° is 13 seconds

Explanation:

Given:

To complete one revolution, the searchlight takes 52 seconds

One revolution = 360°

So,

360° is completed in 52 seconds

Time taken to complete 90° is

                                            = 13 sec

Therefore, time taken to rotate 90° is 13 seconds

whats the

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
