The statement that could be true for g is g(-13) = 20

<h3>How to select the statement that could be true for g?</h3>

The complete question is added as an attachment

The given parameters are:

  • Domain: -20 ≤ x ≤ 5
  • Range: -5 ≤ g(x) ≤ 45
  • g(0) = -2
  • g(-9) = 6

Next, we test the options one after the other.

We have:

<u>Option 1:</u>

g(7) = -1

This means that x = 7 and g(x) = -1

The value x = 7 is outside the domain: -20 ≤ x ≤ 5

So, g(7) = -1 is false

<u>Option 2:</u>

g(-13) = 20

This means that x = -13 and g(x) = 20

The value x = -13 is within the domain: -20 ≤ x ≤ 5 and the value g(x) = 20 is within the range: -5 ≤ g(x) ≤ 45

So, g(-13) = 20 is true

Hence, the statement that could be true for g is g(-13) = 20

A rectangle with a lenght of 6cm has the same area as a square with side length 18cm. what is the perimeter, in cm , of the tria
Gemiola [76]

First, we know the area of a square is side length side length = Area. For this square, the area would be:

18*18=A

324 = A

Now that we know the area that is being referened, we can look at the formula for the area of a rectangle, which is width * length = Area. We know the length and we know the area, so we can fill in these known values and solve for the unknown width.

w*l = A

w*6=324

w=324/6

w=54

So our rectangle has the width of 54 and the length of 6. Lastly, the formula for perimeter is 2w + 2l = P. We can again fill in our knowns and solve for the unknown.

2(54) + 2(6) = P

108 + 12 = P

120 = P

The perimeter of the rectangle is 120 cm.

Complete the proof. Someone please help me answer this!
sammy [17]

Answer:

Step-by-step explanation:

Supplementary angles are two or more angles that add up to give the measure of angle on a straight line (i.e 180^{o}).

It can be deduced from the given question that;

1. <1 and <2 are supplementary, also <1 and <3 are supplementary. Reason: as given in the question.

2. Given statements: m<1 + m<2 = 180^{o}, and m<1 + m<3 =  180^{o}. The reason is the definition of supplementary angles.

3. Statement: m<2 = m<3. The reason is a transitive property.

4. Statement: m<1 + m<2 = m<1 + m<3. The reason is subtraction property of equality.

5.Given statement: <2 ≅ <3. The reason is that definition of congruent angles.

Therefore, <2 ≅ <3.
