Answer:

468

Step-by-step explanation:

Formula for infinite sum of geometric series is;

S_∞ = a1/(1 - r)

Where;

a1 is first term

r is common ratio

We are given;

a1 = 156

r = ⅔

Thus;

S_∞ = 156/(1 - ⅔)

S_∞ = 156/(⅓)

S_∞ = 468

The mode is defined as the number that appears most within a given sequence.
The median is the middle number of a given sequence listed from least to greatest.
Let's look for the mode.
We have:
4
5
7
8
9, 9
10.
9 appears the most, so the mode is 9.
Let's find the median now.
4, 5, 7, 8, 9, 9, 10.
Cross out the smallest number with the largest number until we can no longer do so.
5, 7, 8, 9, 9.
7, 8, 9.
8.
Your median is 8.
Your mode is 9.
I hope this helps!

The <em><u>correct answer</u></em> is:

Translated according to the rule (x, y) →(x + 2, y + 8) and reflected across the y-axis

Explanation:

A translation using the rule (x, y) →(x + 2, y + 8) adds 2 to the x-coordinate and 8 to the y-coordinate. This takes our points and maps them the following way:

A(-5, -2)→(-3, 6)

B(-7, -3)→(-5, 5)

C(-6, -6)→(-4, 2)

D(-3, -5)→(-1, 3)

E(-3, -3)→(-1, 5)

The difference between each of these points and the image points is that the x-coordinates are negated. To do this, we would reflect the points through the y-axis.

Ricky is taking out a personal loan for $12,000 to remodel his kitchen. He would like the lowest monthly payment possible, even

pochemuha

Answer : The correct Option is A.

Step-by-step Explanation :

To solve this we are going to use the monthly payment formula:

$\text{Payment = }\frac{Rate\times Principal}{1-(1+Rate)^{-n}}}$

where, Principal is the amount of the loan

n is the number of periods.

Option A. 13% interest for 36 months compounded monthly

Ricky is taking out a personal loan for $12,000 and term of the loan is 36 months ⇒ n = 36. To find the rate per period, we first need to convert the interest rate to decimal form ⇒ Rate = 0.13.

Now since the bank is charging him the interest rate for the 36 months, we just need to divide the interest rate (in decimal form) by the number of months (36) to find the rate per period

$\implies\text{Rate per period = }\frac{0.13}{36}$

So, putting all these values in the formula, We get monthly payment of loan A = $356.07

Option B : 12% interest for 60 months compounded monthly

interest rate in decimal form = 0.12

By replacing the values in formula the monthly payment of loan B is $212.44

Option C and Option D are obviously denied as the financial charge is not effected by the monthly payments so ricky will not be thinking about the financial charge.

Now, Monthly payments of loan B are significantly low than that of monthly payments of loan A.

So, we can conclude that the correct answer is a. More payments with the 60 month loan will give him the lowest monthly payment.
