Sam is playing with his slingshot and launches a rock straight up in the air with an initial upward velocity of 120 ft/sec. Gravity slows the rock’s upward velocity and it eventually changes directions and falls back down to the ground. The height of the rock is defined using the function h(t) = -16t2 + 120t. What is a reasonable value of the domain, t?

a.) 5 seconds

b.) 1 seconds

c.) 90 seconds

d.) -4 seconds

Plz help ASAP!

Answers

Answer 1

9514 1404 393

Answer:

a) 5 seconds

Step-by-step explanation:

Usually in such scenarios, we're interested in position and time where h(t) ≥ 0. For the given equation, that is 0 ≤ t ≤ 7.5. Values of t that are negative, and values of t that give h(t) a negative value are generally not of interest.

Then, the choice between a domain of [0, 1] and one of [0, 5] will depend on the reason for using the equation. We expect that the longer of these two domains is likely to be more reasonable:

5 seconds

It’s impossible what are you doing Distributed property or solving for x?

Answer:

x = 4.5

Step-by-step explanation:

Let's solve this together!

First you would want to multiply 6 and x:

6×2 = 12

x×2 = 2x

Then you would want to subtract 12 from 3:

3+12 = 9

Then divide 9 by 2:

9÷2 = 4.5

x=4.5

That's it!

Frederick uses his metal detector to search for coins on the beach. He has found both newer and antique coins. He has found 24 newer coins over the past year, witch is 75% of all the coins he has found. What is the total number of coins he has found?

Answers

Answer:

32 coin in all

Step-by-step explanation:

Step one:

given data

let the total coins be x

we are given that 75% of x= 24

Step two:

Mathematically we have

75/100*x= 24

0.75x=24

divide both sides by 0.75

x=24/0.75

x=32coins

Hence the total coins is 32

I WILL GIVE BRAINLIEST IF CORRECT The area of a square is 49 square centimeters. Find the length of a side. Find the length of the
diagonal

Answers

Answer: 7

Step-by-step explanation:

Since squares have the same side lengths

then you need to find a number that multiplies twice that equals 49

7*7 = 49

Answer: Length of a side: 7 / Length of the diagonal: 9.9

Explanation:

Just square root 49, so it becomes 7. That's the side length. In order, to find the diagonal of the square, just use Pythagorean Theorem, a^2+b^2=c^2. Because it's a quadrilateral, all of the sides should equal 7. a^2 would be 7 and b^2 would be 7. 49+49=98. Square root 98 and you would get 9.899... That would be estimated to 9.9.
