Answer: C
Step-by-step explanation:
Based on the dimensions of the regular pentagon, the approximate area can be found to be 342 cm².
<h3>How to solve for approximate area?</h3>
The area of the pentagon can be found by the formula:
= 5 x 1/2 x Length of pentagon x apothem of pentagon
The apothem is:
= √(12² - (14.1/2)²)
= 9.7
The approximate area of the pentagon is therefore:
= 5 x 1/2 x 14.1 x 9.7
= 342 cm²

Answer:
The two will be at the same place in 1/5 of a minute
Step-by-step explanation:
Here, we shall substitute the value 1/2 for x on both sides of the equation
We have this as;
1000(1/5) + 20
= 200+20 = 220
secondly, we have
1,100(1/5) = 220
From the solution, we can see that both sides will be equal and the same amount of distance will have been covered
What this simply mean is that they both will be at the same place in 1/5 of a minute
B=-4 because the7 turns positive then you add -11+7 which is -4
Comment
You can't get to quadrant 4 to quad 2 without 2 steps. The answers tell you that. The question is, did you use a reflection and a y or x translations or 2 reflections or 2 y or 2x translations.
Argument
You can take one point and see if it translate from beginning (purple triangle) to (yellow triangle) end. If two conditions will get you the right answer, then you have to try another point to break the tie.
We'll use Point C.
Choice A: If you reflect C over the y axis, you will go from (-5,1) to (5,1)
If you move C six units down, you will go from (5,1) to (5,-5) which is where C' is.
That is pretty much the answer.
I could confirm it with another point which is the way your should do it.
Try Point A
Choice A: Point A reflects across the y axis going from (-3,4) to (3,4)
Point A translates down by moving from (3,4) to (3,-2) to become A'
Answer reflection and translation in condition A
More Comment
I should do one more for you to show you that it is wrong.
You can try Choice B of the multiple Choice answers.
We will use Point C
If we translate C across the x axis it will go from (-5,1) to (-5,-1)
The we are to translate 1 unit up. We will go from (-5,0) from (-5,-1) That's nowheres near where C' is. Choice B is wrong.
