Answer:
d) 100 feet
Step-by-step explanation:
The x value of the vertex (highest point in this case) is found via -b/2a:
-80/-32 = 2.5
Plug 2.5 into the function:
h(2.5) = -16(2.5)² + 80(2.5)
= - 100 + 200 = 100
Answer:
74 degrees
Step-by-step explanation:
Answers:
Center = (4, 7)
Radius = 7
===========================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
This general circle has these properties:
Based on the equation your teacher gave you, we see that
- h = 4
- k = 7
- r = 7, since 7^2 = 7*7 = 49
Therefore, this circle has center = (4,7) and radius = 7
Side note: The center's y coordinate and radius aren't always the same value.
Answer:
y=-5.5x+-5
Step-by-step explanation:
<em>the slope is -5.5</em>
<em>the y-intercept is what the y-axis is when the x-axis is zero</em>
<em>therefore the y-intercept is -5</em>
hope this helps
have a nice day!!
