To solve for the time an object takes to hit the ground, the equation

<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>

(-2*60/-9.8)^½ = 3.50 seconds.

Jagroop is building a dock at his cottage. The length of the doc is 3 times the width, plus 2. Determine a simplified expression

MissTica

Answer:

Step-by-step explanation:

Let length = y width = x

y = 3x + 2

Perimeter = Sum of all sides (or sum of both lengths and both widths)

2y + 2x

2(3x + 2) + 2x

6x + 4 + 2x

8x + 4

EASY POINTS Find the domain of the graphed function.

Vladimir [108]

Using it's concept, it is found that the domain of the graphed function is given as follows:

D. $-4 \leq x \leq 2$

<h3>What is the domain of a function?</h3>

It is the set that contains all possible input values for the function. In a graph, it is given by the values of x.

In this graph, x assumes values between -4 and 2, inclusive due to the closed circle, hence the domain is given by:

D. $-4 \leq x \leq 2$
