Solving the quadratic function, it is found that the particle returns to the ground after 7 seconds.

<h3>What is the quadratic function for the particle's height?</h3>

The particle's height after t seconds is modeled by the following equation:

s(t) = -16t² + v(0)t.

In which v(0) is the initial velocity of the particle, which in this problem is of 112 ft/s, hence:

s(t) = -16t² + 112t.

The particle hits the ground when s(t) = 0, hence:

s(t) = 0

-16t² + 112t = 0

-16t(t - 7) = 0.

Hence the non-trivial solution is:

t - 7 = 0 -> t = 7.

The particle returns to the ground after 7 seconds.

Tell whether the ordered pair is a solution of the system of linear equations.
Lana71 [14]

To figure out if the ordered pairs are a solution to the equations, you would need to plug in the points. Your points are ordered as (x,y)

You would plug in the number that's in the x spot in x, and the number in the y spot in y.

Let's start of with the first problem:

First thing you would do is plug in (-1) to x, and 6 to y.

Your equations would look like this:

6(-1) + 3(6) = 18

2(-1) + 6 = 7

What you would now do is solve the equations. When you solve them, you would get these answers

12 = 18

4 = 7

For #1, it would be no solution because the numbers do not equal each other. (Fun fact) If one of them ends up as a solution, but the other is no solution, the answer would be no solutions because BOTH of them have to be a solution to the equations given in order to be a solution.

If you do the same strategy, (plugging in the numbers to x and y), you would get the rest of the answers for the problems.

I hope this helps, if you need any more assistance, I would be glad to help!

The next stop on the road trip is the zoo! jacob goes to find his favorite animal, the giraffe. jacob wonders how tall the talle
lapo4ka [179]
1 foot = 12 inches
Height of Jacob = 5 feet 6 inches = 5 *12 + 6 = 66 inches
Jacob's <span>shadow = 3 feet = 36 inches

</span>giraffe's shadow = <span>5 feet 9 inches = 5 * 12 + 9 = 69 inches

</span><span>by the ratio and proportion

∴ </span>Height of Jacob/Jacob's shadow = Height of giraffe/giraffe's shadow

∴ 66/36 = Height of giraffe/69

∴ Height of giraffe = 69 * 66/36 = 126.5 inches = 10 feet 6.5 inches
