Thread: summer school T-T

i need help with some problems
i will add more to this post

for each direct variation, find the constant of variation. then find the value of y when x = -5

y=2 when x=7


AVIATION
a speed of 60 mi/h is equal to a speed of 88 ft/s find the speed in mph of an aircraft travaling 1000ft/s

1. I'm going to assume that y varies directly to x.

If y varies directly to x, then


K is the constant of variation. Find constant of variation using the numbers given in the question, then replace in the equation above. Then find y when x = -5.

2.
Given:


Using this given relation, you can find out how many feet are there in 1 mile:









Now, let's divide this into two parts.
a. Find how many miles are there in 1000 ft.
b. Find how how many hours in a second.
b. Substitute.

a.


b. There are 3600 seconds in an hour. So how many hours are there in one second?


Can you continue?

idk

I'll leave the computations for you. :-)

fine
