2(4z - 6 - 6) = 170 - 46

2(4z - 12) = 124    |use distributive property: a(b - c) = ab - ac

8z - 24 = 124      |add 24 to both sides

8z = 148      |divide both sides by 8

z = 18.5

I don’t know how to do any of this
mojhsa [17]

Answer:

The length of x in #1 is 15.57

Step-by-step explanation:

Let's use #1 as an example to teach show you how to do this. In a right triangle we can solve these using trig. In this particular one, we have the measure adjacent to the angle and we are looking for the one opposite of the angle. So we look at all the trig functions and select the one that uses both of those two terms.

Sinα = Opp/Hyp

Tanα = Opp/Adj

Cosα = Adj/Hyp

As you can see, Tan is the function we are looking for. So we plug in all known information into that equation.

Tanα = Opp/Adj -----> Plug in known values

Tan(60) = x/9 ----->Calculate out the trig function

1.73 = x/9 -----> Multiply by the denominator to solve

15.57 = x

a ball is dropped from a height of 20 feet above the ground. The velocity v(s) of the ball after it has travelled a distance of
Lana71 [14]
<h2>We know that</h2>

The initial height is 20 feet above the ground.

The function to model the velocity is

v(s)=60s

Where <em>s</em> represents the distance in feet.

Mathematically, this function has all real numbers as a domain. However, that will no make sense for this situation, because it would use negative numbers for the distance <em>s</em> which does not make sense.

Therefore, the domain, in this case, would be all real numbers greater than or equal to zero, but less than or equal to 20.

<em>The reason for this domain is that the ball will go from 20 feet above the ground to zero feet on the ground.</em>

Using interval notation would be
