Answer:

It is irrational and equal to 5 times the square root of 2.

Step-by-step explanation:

The statement that is true about the expression:

( √(32) ) + √2

( √(16 * 2) ) + √2

( √(4²) *√2 ) + √2

( 4 *√2 ) + √2

( √2+√2+√2+√2 ) + √2

...and this is ( 4 ) + 1 times √2

The answer is 5 times √2

So the expression is irrational and equal to 5 times the square root of 2.

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.
