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).
Answer:
points srru
Step-by-step explanation:
Point slope eqaution is
y-y1=m(x-x1)---------equation1
find m slope=y2-y1/x2-x1
m=-3+1/3+4=-2/7
so put those all values in eqaution 1
<span>(x1, y1) as (-4, -1).</span>
y+1= - 2/7(x+4)
Answer:
d > 5
Step-by-step explanation:
The circle is open which means there is no line underneath the sign, the way the arrow is facing is the same way the sign should be facing.
Answer:
Apple- 14 Maple- 154
Step-by-step explanation
Since 11 x n - n is equal to a number that ends in 10, 20 etc. and the number has to be a multiple of 11 for the maple tree, and the difference has to stay the same throughout two all we need to find is 15 x n = a number that is divisable by 10. 15 x 10 = 150 so that's the age of the trees this year, and the difference between the trees is 140 so it corresponds with our rule. and the multiple of 11 that the difference is 140 is 11 x 14 = 154 and 154 - 11 = 140. Therefore the apple tree is 14 years old and the maple tree is 154 years old.
