Let speed of water leaking out = x/h
water left in the tank after 24h=20-(speedxtime)
=20-(24x)
=14
20-24x=14
24x=6
x=1/4
Therefore, answer is (a).
<span>Draw a graph. Label the x- and y- axis. Choose a <span>range </span>that includes the maximums and minimums from the given data.</span><span> For example, our x-values go from 3 to 6.3, so a range from 3 to 7 would be approprite.
</span>
(x + x² + 4x) 3
3(x) + 3(x²) + 3(4x)
3x + 3x² + 12x
we are given
we have to solve it by completing square method
step-1: Move 5 on right side
step-2: Break middle term
step-3: Add 6^2 both sides
step-3: Solve for x
we wil get two values
First value is
add both sides 6
Second value is
add both sides 6
so, solutions are
