The missing digit could be any number from 0-4 because if it were any from 5-9 then it would be rounded to 16,000.

A=pir^2 solve for pi

VashaNatasha [74]

Given problem;

A = $\pi$ r²

Solve for π;

To solve for π implies that we make it the subject of the expression.

So;

A = π r²

Now multiply both sides by $\frac{1}{r^{2} }$

So;

A x $\frac{1}{r^{2} }$ = $\pi$ x r² x $\frac{1}{r^{2} }$

r² cancels out from the right side and leaves only π;

π = $\frac{A}{r^{2} }$

So $\pi = \frac{A}{r^{2} }$

Answer:

1) 202.52

2) P107089

Step-by-step explanation:

Compound interest is calculated as

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

A = compounded interest

P = present value

r = interest

n = number of times interest applied

t = time taken

A = 200 (1 + 0.25%/30)^(30 * 5)

A = 200 (1 + 8.3*10^-5)^150

A = 200 * 1.0126

A = 202.52

Present Value Annuity Due is usually given by the formula

P = c*((1-(1+ i)^(-n))/i)*(1 + i ), where

P is the present value

C is the Cash flow per period

i is the interest rate and

n is the number of payments

P = 10000*((1-(1+ 12/1200)^(-1*12))/(12/1200))*(1+12/1200)

P = 113676

Also, it's worthy of note that

Effective Annual Rate = [(1 +stated rate/no. of compounding periods) ^no of compounding periods - 1]* 100

EAR = ((1+12/(12*100))^12-1)*100

EAR = 12.68%

And lastly, the

Future value = present value*(1+ rate)^time

113676 = Present value*(1+0.1268)^0.5

Present Value = 113676 / 1.1268^0.5

Present Value = 113676 / 1.0615

Present value = 107089

Use the given facts about the functions to find the indicated limit.

oksian1 [2.3K]

Answer: Option b.

Step-by-step explanation:

1. You can rewrite it as following:

$\lim_{x\to \ -6} 2$

This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 2, no matter the value of x.

$\lim_{x\to \ -6} 2=2$

$\lim_{x\to \ -6} 1$

This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 1, no matter the value of x.

$\lim_{x\to \ -6} 1=1$

2. Then:

$\lim_{x\to \ -6} (f/g)(x)=2/1=2$

3. The answer 2.
