Answer:

x = 6

Step-by-step explanation:

Vertical angles in a geometry are equal. Hence m<A = m<B

Given that

m<A = 3x - 9

m<B - x+3

Then 3x - 9 = x+3

3x - x = 3 + 9

2x = 12

Divide both sides by 2

2x/12 = 12/2

x = 6

Hence the value of x is 6

Find the domain and range of radical function

Tju [1.3M]

The radical function is 3√x + 1.

Since the cubic root of zero is zero, 0 would be x.

Add zero and one, which gives you 1. 1 is y.

You get (0,1)

Since this is a positive radical, it would be going to the top right.

So, the domain is x ≥ 0

the range is y ≥ 1

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerte

gulaghasi [49]

Answer:

The force exerted by the weight lifter is 81.7 N.

Step-by-step explanation:

We can find the force exerted by the weight lifter using the definition of work:

$W = F*d$ (1)

Where:

F: is the force

d: is the displacement

We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:

$F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N$

Therefore, the force exerted by the weight lifter is 81.7 N.

I hope it helps you!
