Answer:
It forms a 90 degree angle
Step-by-step explanation:
Since a circle is 360 degrees, 1/4 of that would be 90.
$4.50 you just do 18/4 to get ur answer per hour
Answer:
(2x+5)(3x-2)
Step-by-step explanation:
6x²+11x-10
6x²+15x-4x-10
3x(2x+5)-2(2x+5)
(2x+5)(3x-2)
I assume a unit rate is simply ms^-1 or whatever.
In order to determine m/s one must make the "per whatever" part equal to 1. In this case it is seconds, so we must make seconds equal to 1.
If in 17 seconds it travels 238 metres, that means in 1 second it travels 238/17m=14m
Therefore the unit rate (speed) of the car is 14m/s or 14ms^-1
F(x)=2x+3. easy as that, just replace y with f(x)
