Quadrilateral ABCD is located at A(−2, 2), B(−2, 4), C(2, 4), and D(2, 2). The quadrilateral is then transformed using the rule (x − 2, y + 8) to form the image A'B'C'D'. What are the new coordinates of A', B', C', and D'? Describe what characteristics you would find if the corresponding vertices were connected with line segments.

Answers

Answer 1
Answer: The new coordinates are A(-4, 10), B (-4, 12), C (0, 12) and D (0, 10). If you were to connect these, it would take the shape of a rectangle.

Which line is perpendicular to the line y=2/3x +3?Y=2/3x-1
Y=-2/3x+1
Y=3/2x+7
Y=-3/2x+7

Answers

The line that is perpendicular to the given line, is:

y = (-3/2)*x + 7

How to get the perpendicular line?

Remember that two lines are perpendicular if the slope of one is equal to the opposite of the inverse of the other slope.

Here we start with the line:

y = (2/3)*x + 3

So the slope is 2/3.

The opposite of the inverse of that would be -(3/2). Then any line with a slope of -3/2 will be perpendicular to the given line. So we conclude that the correct option is:

Y = -(3/2)x+7

Tom has taken out a loan for college. He started paying off the loan with a first payment of $200. Each month he pays, he wants to pay back 1.2 times as the amount he paid the month before. Explain to Tom how to represent his first 30 payments in sigma notation. Then explain how to find the sum of his first 30 payments, using complete sentences. Explain why this series is convergent or divergent.

Answers

Answer:

In this geometric series, a represents the first term, what he pays back monthly is the common ratio which is 1.2, and the first 30 payments are what is being used to find the total amount which is represented by n. Thus, a=$200, n=30 and r=1.2. The sum is found by sn=(a((r^n)-1))/(r-1), which will be 200((1.2^30)-1))/(1.2-1). The solution is = $ 236,376 and the series is divergent because of the common ratio being greater than 1.

Step-by-step explanation:

This is a geometric series. The first payment represents the first term, a. The number of times he wants to pay back for subsequent payments represent the common ration, r. The first 30 payments represents the number of terms to use in finding the sum, n.

Hence, a = $ 200, n = 30 and r = 1.2.

The sum of a geometric sequence is given as:

Sn = (a((r^n)-1))/(r-1)

     =(200((1.2^30)-1))/(1.2-1) 
  
     = $ 236, 376. 31

Explain why this series is convergent or divergent.

Since the common ratio, r, is greater than 1, the series is divergent

What is 9/10 - 1/10 equal.

Answers

9/10 - 1/10 = 8/10. 
When subtracting fractions with like denominators, you really only need to worry about the numerators. 9 - 1 = 8, so the answer is 8/10.
As we can see, both 8 and 10 are divisible by 2, so we can simplify the answer a bit.
8 / 2 = 4
10/ 2 = 5
The final simplified answer is 4/5.
Hope that helped =)
Since the denominators are the same, we can just combine the numerators together.

(9-1)/(10)

Now, we just have to subtract the numerators to get our new fraction.

(8)/(10)

But, our fraction is not in simplest form yet. We can find the GCF of 8 and 10 and then divide the numerator and denominator by it.

The GCF = 2, so now we can divide.

8 / 2 = 4 \n 10 / 2 = 5 \n \n

Gather the new numerator and denominator to get our simplified fraction.

The final result is: 4/5 or 0.8

Answer:

4.5 per package

Step-by-step explanation:

Though they give us 4 different pairs of values on the table, we only need 1 pair to solve this question. For simplicity, lets chose the pair of whole numbers:

54 : 12

This is the ration of servings to packages, or the servings per package.

To get our answer, we must find how many servings per 1 package, so we need to divide by 12:

(54)/(12) : (12)/(12)

   =

4.5 : 1

This means that there are 4.5 servings per 1 package!

Hope this helps!
