Answer:
slope is 1/3
Step-by-step explanation:
notice the points on the line, from the first point go one square up and three to the right, thats how i got 1/3
J is correct. the scale is balanced, so x = 1. there are 9 1’s on the right, and 6 1’s on the left. there are 3 more blocks, and they would have to each be 1.
It will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
<h3>How to determine the time to hit the ground?</h3>
The function is given as:
h = –.025t^2 + 4t + 50
Set h = 0.
So, we have:
–.025t^2 + 4t + 50 = 0
Using a graphing calculator, we have:
t = -11.652 and t = 171.652
Time cannot be negative.
So, we have:
t = 171.652
Hence, it will take the roller coaster 171.652 seconds to pass over the hill and reach ground level

Answer:
y = (x-5)²+7
Step-by-step explanation:
i graphed x²-10x+32 and found the vertex is at (5,7)
i used the y-intercept as a point on the curve in the formula:
y = a(x-h)²+k
32 = a(0-5)²+7
subtract 7 from each side to get:
25 = 5²a
25 = 25a
a = 1
y = (h-5)² + 7
