Check the pictures below.
if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.
if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is
h(s) = -4.9(s - 2)(s + 1).

Explanation
3 rectangles 12x15, 6x3,6x9
multiple each square then add all the totals
102 is your answer to your problem.
It will take 3 months to wire 55 houses. She can wire 18 a month at 4.5 pee week. So you that's roughly 18 a month. 18x3=54 if there is 4 weeks in a month. If you have 5 weeks in the month then it will bend 22 a month. 22x2.5=55 so in this case just 2 and a half months to wire 55 houses at 4.5 houses a week.
Answer:
Step-by-step explanation:
<u>Given line:</u>
Perpendicular lines have negative-reciprocal slopes.
<u>We will have a line:</u>
<u>Use the coordinates of the given point to find the value of b:</u>
- -1 = -3(5) + b
- -1 = - 15 + b
- b = 14
<u>So the line is:</u>
