Quadratic is the y=2x^2

that is the parabola one

when will the exponential one be higher than the parabola?
that is, hmm, find the intersection points
we can see that x=1 is an intersection point
we see that it is between the intersection points
if we use our calculator
intsersect at x=-0.578621 and 1
so it is the one from -0.5 to 1
that is the 3rd option

-0.5≤x<1

The Apollo's chariot, a rollercoaster at Busch gardens, moves at 110 feet per second. The equation of the ride can be represente
GREYUIT [131]

Answer:

169.39 feet.

Step-by-step explanation:

We have been given that the Apollo's chariot, a roller coaster at Busch gardens, moves at 110 feet per second. The equation of the ride can be represented by the equation h(t)=-16t^2+101t+10. We are asked to find the maximum height that the ride can reach.

To  find the maximum height that the ride can reach, we need to find y-coordinate of vertex of parabola because our given equation is downward opening parabola and its maximum point will be the vertex.

First of all, we will find x-coordinate of vertex using formula \frac{-b}{2a}.

\frac{-101}{2(-16)}=\frac{101}{32}=3.15625

Now, we will substitute t=3.15625 in our equation to find y-coordinate of vertex as:

h(3.15625)=-16(3.15625)^2+101(3.15625)+10

h(3.15625)=-16(9.9619140625)+101(3.15625)+10

h(3.15625)=-159.390625+318.78125+10

h(3.15625)=169.390625

h(3.15625)\approx 169.39

Therefore, the ride will reach to a maximum height of 169.39 feet.169.39 feet.

Do the ratios 2/1 and 16/8 form a proportion?
satela [25.4K]

Answer:

Yes, it does. A way to confirm this is you can divide 16/8 which is 2 and 2/1 which is also 2 to get your answer.

If an adult male’s height is h inches over five feet, his approximate normal weight is given by the expression 6.2(20 + h). What
Harlamova29_29 [7]
If this male is 5 ft 9 inches tall, he is 9 inches over five feet tall.  Thus, h = 9.
Evaluate 6.2(20+h):

6.2(20+9) = 6.2(29) = 179.8 lb.
