Step-by-step explanation:
h(t) = -16t² + 16t + 12
h(t) = -4(4t² - 4t - 3)
h(t) = -4(2t - 3)(2t + 1)
When h(t) = 0, we have t = 1.5 or t = -0.5.
Hence the zeroes are 1.5 and -0.5.
The question asks us for something like this: something - 8 = something
In this case, the second choice, or B) 9 - 8 = 1 would be the correct answer. Hope this helps and have a great day!
Answer:
The midline of the function is y = 2.
Step-by-step explanation:
Midline is the horizontal line that passes exactly in the middle between the graph's maximum and minimum points.
The midline of a sinusoidal function passes exactly in the middle of its extreme values.
Since the amplitude of a sinusoid is equal to the vertical distance from its midline to one of its extrema, we can calculate the midline using one of the following formulas.
<em>midline = max value − amplitude</em>
<em>midline = min value + amplitude</em>
According to the graph, the maximum value of the function is 5.5, and the amplitude is 3.5.
So, the midline is
<em>midline = max value − amplitude</em>
<em>midline = </em>5.5 − 3.5 = 2
14. 2x-1 = 0, x+7=0
x = 1/2, x = -7
15. x^2 + 3x - 10 = 0
(x + 5)(x - 2) = 0
x = -5, x = 2
16. x^2 - 25 = 0
(x-5)(x+5)
x = 5, x = -5
