Use the ratio test to determine whether the series is convergent or divergent.2 +4/2^2 + 8/3^2 + 16/4^2 +

Answers

Answer:

The result is 2 > 1. Hence, the series diverges

Step-by-step explanation:

You have the following series:

[tex]2+\frac{4}{2^2}+\frac{8}{3^2}+\frac{16}{4^2}+...+\frac{2^n}{n^2}=\sum_{i=1}^{i=n}a_n[/tex]   (1)

You use the ratio test to determine if the series is convergent or divergent. The ratios test is given by:

[tex]\lim_{n \to \infty} \frac{a_{n+1}}{a_n}[/tex] (2)

Then, you replace the series (1) in (2):

[tex]\lim_{n \to \infty} \frac{\frac{2^{n+1}}{(n+1)^2}}{\frac{2^n}{n^2}}= \lim_{n \to \infty} \frac{(2^n2)(n^2)}{2^n(n+1)^2}\\\\\lim_{n \to \infty} \frac{2n^2}{n^2+2n+1}= \lim_{n \to \infty} \frac{2n^2}{n^2[1+\frac{2}{n}+\frac{1}{n^2}]} \\\\\lim_{n \to \infty} \frac{2}{1+\frac{2}{n}+\frac{1}{n^2}}=\frac{2}{1+0+0}=2[/tex]

In the ratio test you have that if the limit is greater than 1, the series diverges.

The result is 2 > 1. Hence, the series diverges.

Write the phrase as a unit rate.
$13.50 for 3.6 lb
Alb
Please help FAST

Answers

Answer:

$3.75/lb

Step-by-step explanation:

First, let's set up a proportion. The top number represents the cost, while the bottom number represents how many pounds. In order to get a unit rate, we need to figure out how much it costs for 1 pound.

[tex]\frac{13.5}{3.6} =\frac{x}{1}[/tex]

Now, cross multiply. To cross multiply, you would multiply 13.5 by 1 and 3.6 by x.

[tex]13.5 * 1 =13.5\\3.6*x=3.6x[/tex]

Set these two equal to each other.

[tex]13.5=3.6x[/tex]

Divide both sides by 3.6 to get x.

[tex]\frac{13.5}{3.6} =\frac{3.6x}{3.6}\\x=3.75[/tex]

For unit rates, you have to write your answer as per unit. To do that, put a slash next to your answer, and then your unit.

The sale price of a drum kit in the UK is 950 Pounds + VAT (Value Added Tax), where VAT is a sales tax of 20%. After some negotiation, the owner of the store agrees to give Bob a 12% discount on the drum kit. What is the total price that Bob pays, including VAT? Answer in Pounds and round your answer to the nearest pence (1 pence=1100Pound).


Note: VAT is a sales tax that gets calculated before a discount is applied.

Answers

Answer:

Step-by-step explanation:

Sale price = 950 pounds + vat

Vat = 20%

Value vat = 20/10 × 950 = 190 pounds.

Since the vat is calculated before a discount is applied, it means that the amount on which the discount was applied is

950 pounds

The value of the discount would be

12/100 × 950 = 114 pounds

The amount to be paid including vat is

(950 - 114) + 190 = 1026 pounds

Complete the equation of the line whose slope is -2 and y-intercept is (0,-8)

y=

Answers

Answer:

y = -2x - 8

Step-by-step explanation:

We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.

We already know that the slope is -2, so that means m = -2.

We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.

Thus, our equation is: y = -2x - 8.
