A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?

Answers

9514 1404 393

Answer:

1.375 seconds35.25 feet

Step-by-step explanation:

A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).

Here, we have ...

  h = -16t^2 +44t +5

  t = -44/(2(-16)) = 11/8 = 1.375

It takes 1.375 seconds for the ball to reach its maximum height.

The height at that time is ...

  h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25

The maximum height is 35.25 feet.

Since it’s angle K, 51 will be the hypotenuse, 45 will be the adjacent, and 24 will be the opposite. And since we’re looking for tan, which is the opposite over the adjacent, 24 is the opposite, and 45 is the adjacent. In conclusion, tan K = 24/45

A Ferris Wheel has a radius of 16 feet. How far will you travel if you take a ride that goes around 5 times? Round answer to the nearest hundredth and for pi use π = 22 7 .

Answers

Answer:

502.85 feet

Step-by-step explanation:

Given that,

The radius of a Ferris wheel, r = 16 feet

We need to find how far will you travel if you take a ride that goes around 5 times.

Distance = 5×2πr

So,

= 10πr

[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]

So, the required distance is 502.85 feet.

Mr. Armstrong went to Target to buy four pairs of dress socks. There was a 30% off sale
on the socks, and his total bill before tax was $14. What was the price of each pair of socks
before the sale?

Answers

Answer: $5

Step-by-step explanation:

We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.

Therefore, let the price of the socks be represented as x.

70% of x = 14

70/100 × x = 14

0.7 × x = 14

0.7x = 14

x = 14 / 0.7

x = 20

Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:

= $20 / 4

= $5
