Answer:
The height of the trough is about 1.5 ft
Step-by-step explanation:
If each cubic foot of water contains about 7.5 gallons.
Then; 315 gallons is about 
Let h be the height of the trough, then

This implies that;

Divide both sides by 28 to get:


The height of the trough is about 1.5 ft
7x-3=7x+5
+3 +3
7x=7x+8
-7x-7x
x=8
Answer:
V= πr^2 * height
Step-by-step explanation:
(2,1)
Draw a line on y=-2 and reflect the dot on the other side. The x doesn’t change, only y changes. So only option is (2,1).
That would become
(XY)^4/3 .
The exponent is still rational. Sorry.
