RANGE gives you the possible y values. [4, ∞) means the lowest y value - y coordinate of the vertex is 4 and the y is increasing from 4 upwards towards infinity. The graph opens up.
DOMAIN gives you the possible x's. As you can see no restrictions.
Answer:
cos theta = adja/ hypo
adja=8
hypo=17
cos theta= 8/17=0.47
theta= cos^-1 0.47
theta=1.0815
to fine missing side, use Pythagoras
hypo²= oppo² + adja²
17²= oppo² + 8²
289-64=oppo²
oppo²=225
oppo=15
It takes the faster pump 12 minutes to fill the tank.
Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.
Kent can paint the room 1/5
luannda can paint the room 1/3
(3+5) (5*3) = 8/15 or 0.53 th of the room together but just for kent would be 1/5
