Answer:
[-7, ∞ )
Step-by-step explanation:
I'm assuming that the function is y = (x + 8)² - 7
To find the range, we need to find the vertex,
Vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the location of the vertex. Our equation has a = 1, h = -8, and k = -7. Since a > 0, the parabola opens up, so the upper limit of the range is infinity. To find the lowest value of the range, we find the vertex.
Here the vertex is at point (-8, -7), so -7 is the lower limit of the function's range.
The range is [-7, ∞ )
Hi so you would turn 25% into a decimal(0.25) and you would multiply that times 9.99! And after you get the answer you would subtract it from the 9.99!
Answer:
fb
Step-by-step explanation:
50=16t^2
Divide both sides by 16
3.125=t^2
Find the square root of both sides (approximated)
1.77= t
Final answer: F
