Answer:
4/5 = 80%
Step-by-step explanation:
4/5 can be multiplied by 20 to get 80/100. Percent is out of hundredths so it becomes 80%.
Answer:
I think its B
Step-by-step explanation:
Answer:The correct awnser is D
Step-by-step explanation:
g- acceleration due to gravity=9.8ms^-2
acceleration of performer= 1.5g = 1.5 x 9.8ms^-2 = 14.7ms^-2
<h2>The y-value of the vertex is 49</h2>
Step-by-step explanation:
Given, ![f(x)=-(x-3)(x+11)](https://tex.z-dn.net/?f=f%28x%29%3D-%28x-3%29%28x%2B11%29)
![f(x)=-x^{2} -8x+33](https://tex.z-dn.net/?f=f%28x%29%3D-x%5E%7B2%7D%20-8x%2B33)
The vertex of the parabola
occurs at
.
For the given parabola, ![a=-1,b=-8,c=33](https://tex.z-dn.net/?f=a%3D-1%2Cb%3D-8%2Cc%3D33)
So, vertex occurs at ![x=\frac{-(-8)}{2(-1)}=-4](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-%28-8%29%7D%7B2%28-1%29%7D%3D-4)
At this point ![f(x)=-(-4-3)(-4+11)=7*7=49](https://tex.z-dn.net/?f=f%28x%29%3D-%28-4-3%29%28-4%2B11%29%3D7%2A7%3D49)
∴ At vertex, y-value of
is 49.
