The graph of
![f(x)=-16 t^{2}+80](https://tex.z-dn.net/?f=f%28x%29%3D-16%20t%5E%7B2%7D%2B80%20)
is shown in the graph below.
The graph is of ∩-shape when the constant
![a](https://tex.z-dn.net/?f=a)
of the quadratic equation
![a x^{2} +bx+c](https://tex.z-dn.net/?f=a%20x%5E%7B2%7D%20%2Bbx%2Bc)
is negative
Answer:
550 miles
Step-by-step explanation:
![Distance=Speed\times Time](https://tex.z-dn.net/?f=Distance%3DSpeed%5Ctimes%20Time)
![Distance = 110mph \times 5h = 550\ miles](https://tex.z-dn.net/?f=Distance%20%3D%20110mph%20%5Ctimes%205h%20%3D%20550%5C%20miles)
Let the price of each shrub be x 4x + 17.50 = 53.50 4x = 53.50 - 17.50 x = 36/4 = <span>$9</span>
Answer: m= 1/420
Step-by-step explanation:
5x + 6y - 6y - 425x = 42
5x -425x = 42
0 = -420x - 42
m = -420
slope of a perpendicular line = 1/420
if that helps.
Answer:
For y=37, x= -4
Step-by-step explanation:
We have to find the value of x, when y=37 is the given value for the given equation
![y=9-7x](https://tex.z-dn.net/?f=y%3D9-7x)
Putting the value of y=37 in the equation to find the 'x'
![y=9-7x](https://tex.z-dn.net/?f=y%3D9-7x)
![37=9-7x\\7x=9-37\\7x=-28\\x=-4](https://tex.z-dn.net/?f=37%3D9-7x%5C%5C7x%3D9-37%5C%5C7x%3D-28%5C%5Cx%3D-4)
So, for the value of y=37, the value of ![x=-4](https://tex.z-dn.net/?f=x%3D-4)
