The height h, in feet of a model rocket t seconds after launch is given
by the equation h= 245t - 16t?. As the rocket descends, it deploys
a recovery parachute when it reaches 325 feet above the ground.
Express your final answer to the nearest tenth place.
What is the maximum height of the rocket?

Answers

Answer:

h_max = 324.09 ft

Step-by-step explanation:

The correct equation is;

h = 245t - 16t²

We are told that as the rocket descends, it deploys

a recovery parachute when it reaches 325 feet above the ground.

Thus;

245t - 16t² = 325

Thus;

16t² - 245t + 325 = 0

Using quadratic formula, we have the roots as;

t = 1.47s or 13.85s

We will pick the higher value.

Thus;

Maximum height will occur at t = 13.85 s

Thus, plugging in 13.85 for t into h = 245t - 16t², we have;

h_max = 245(13.85) - 16(13.85)²

h_max = 324.09 ft

Which equations could you solve using the addition property of equality? Check all that apply.
4+ y = 100
y -4 = 100
4y = 100 4 + 100=y
100 = y - 5

Answers

Answer:

4 + y = 96 = 100

y = 104 - 4 = 100

4 y = 25 = 100 4 + 100 = y = 104

100 = y = 105 - 5

Step-by-step explanation:

Plz mark me as brainliest have a good day

The equations could you solve using the addition property of equality is

y- 4 = 100.

We have to apply the property of addition equality

Now,

4 + y = 100

y= 96

and, y -4 = 100

y = 104

and, 4 y = 100

y= 25

and, 100 = y - 5

y= 105

Thus, the required equality is y- 4 = 100.

If 3 quarts of paint are needed for 50 ft of fence, how many quarts are needed for 300 ft of fence?

Answers

Answer:

Step-by-step explanation:

First, you would do a proportion

[tex]\frac{3}{50}[/tex]=[tex]\frac{x}{300}[/tex]

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.

To paint 300 feet of fence we need 18 quarts of paint.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.

m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.
