Given:

Goryan [66]

Answer:

a.Converge

b.Diverge

Step-by-step explanation:

We are given that

$A_n=\frac{6n}{-4n+9}$

$\lim_{n\rightarrow \infty}A_n=\lim_{n\rightarrow \infty}\frac{6n}{-4n+9}=\frac{6n}{n(-4+\frac{9}{n})}$

$\lim_{n\rightarrow \infty}\frac{6}{-4+\frac{9}{n}}=\frac{6}{-4}=\frac{-3}{2}$

Because $\frac{9}{\infty}=0$

Hence, sequence An converges to $\frac{-3}{2}$ when n tends to infinity or - infinity.

$\sum_{n=1}^{\infty}An=\sum_{n=1}^{\infty}\frac{6n}{-4n+9}$ =diverges

Necessary condition for a series to converge :

$an\rightarrow 0$ when n tends to infinity .

But $A_n$ tends to $\frac{-3}{2}$ when n tends to infinity.

Therefore, given series is divergent.

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

A model rocket was built using a scale factor of 1:15 if the height of the actual rocket is 9.9m, what is the height of the mill

beks73 [17]

Answer:

660 mm

Step-by-step explanation:

we know that

The scale factor is $\frac{1}{15}$

That means

1 unit in the model represent 15 units in the actual

1 m in the model represent 15 m in the actual

To find out the height of the model rocket, divide the height of the actual rocket by 15

$9.9\ m=\frac{9.9}{15}= 0.66\ m$

Convert m to mm

Remember that

$1\ m=1,000\ mm$

To convert meters to millimeters, multiply by 1,000

$0.66\ m=0.66(1,000)=660\ mm$
