Answer:

A root of the quadratic or an x-intercept.

Step-by-step explanation:

When the rocket hits the ground at (8, 0), we can see that it took 8 seconds to reach 0 height.

This can mean multiple things.

1. It tells us one of the x-intercepts of the graph.

2. It tells us a root of the quadratic function.

Answer:

the points are called the x intercepts, the zeros of the function, or the roots of the equation.

Step-by-step explanation:

When the parabola crosses the x axis, the points are called the x intercepts, the zeros of the function, or the roots of the equation. In this case it is the point where the rocket hits the ground.

<h3>Answer:</h3>

208 ft²

<h3>Explanation:</h3>

Generally, carpet covers the entire floor area, so the ceiling height and door area are irrelevant. The floor area is the product of its length and width.

... floor area = (16 ft)×(13 ft) = 208 ft²

_____

If your 3" overhang has to do with carpeting the floor, then the required area would seem to be (16.5 ft)×(13.5 ft) = 222.75 ft².

To play a game, a number cube with sides numbered 1 through 6 is rolled and a fair coin is flipped.

aleksley [76]

Answer:

16.7%

Step-by-step explanation:

Please check below attachment for sample space table

Firstly, we have the total number of possible results as 12

From the 12, the probability of flipping a head is 6/12

Rolling either a 3 or a 5 is the sum of places we have both divided by the possible total of 12

we have this as ; 2/12 + 2/12 = 4/12

The term ‘AND’ means we have to multiply the two probabilities as follows;

4/12 * 1/2 = 1/6 = 0.1667

To the nearest tenth, we have this as 16.67% which is 16.7%
