Answer:
1.) B.
the horizontal distance covered by
2.). D (0)
3.) A ( infinity )
Step-by-step explanation:
1.) Since it is a quadratic function which models the height of the plane, in feet, relative to the ground, at a horizontal distance of x feet. Therefore,
The range = height
The domain = distance covered
2.) Since she launched it from the top of a building. That is, from a starting point, then domain = 0
3.) Since the plane traveled a horizontal distance of 50 feet before landing on the ground. This mean that it can travel further. Therefore the domain can be to infinity
1) 8
2) 14.5*2=29
3) 7x+5=2*13, 7x+5=26, 7x=21, x=3
4)d(1)=2r,
if r increase 3 times, d(2)=2*(3r)
d(2)/d(1)=(2*3r)/2r=3,
so diameter increases 3 times
Answer:
$60
Step-by-step explanation:
To find how much Zoe paid before the sales tax and tip, we first need to consider the amount she paid in sales tax and tips.
Sales tax + Tips = $18.60
Let x = original price
Sales tax = 11% * original price
Sales tax = 0.11 * x
x= 0.11x
Tips = 20% * original price
Tips = 0.20 * x
x = 0.2x
Now that we have a value for both the sales tax and tips, we can then proceed to find the original price by:
0.11x + 0.2x = 18.60
0.31x = 18.60
Now we need to divide both sides by 0.31 to find x.
![\dfrac{0.31x}{0.31}=\dfrac{18.60}{0.31}](https://tex.z-dn.net/?f=%5Cdfrac%7B0.31x%7D%7B0.31%7D%3D%5Cdfrac%7B18.60%7D%7B0.31%7D)
x = 60
Zoe's dinner before the sales tax and tips was $60.
