Find a unit vector in the same direction as the given vector d=7/4i+4/9j

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)

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

the answer is b.

surface area: 169π

volume: 366π
