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

It's going to be kind of crazy, but you need to use Pythagorean's Theorem for this.  That will look like this: (2 \sqrt{x} +1)^2=( \sqrt{x} +1)^2+(2 \sqrt{x} )^2.  FOIL out the left side to get 4x+4 \sqrt{x} +1.  FOIL out the first of the 2 expressions on the right to get x+2 \sqrt{x} +1,  and the second of the 2 to get 4x.  Our equation now looks like this:  4x+4 \sqrt{x} +1=x+2 \sqrt{x} +1+4x.  Combine like terms to get an equation that still has square roots in it that we have to deal with:  4x-x-4x=-2 \sqrt{x}  and x=2 \sqrt{x}.  We will square both sides to get rid of the square root sign.  x^{2} =2x.  This is a polynomial now that can be factored to solve for x.  Bring the 2x over by subtraction and set the polynomial equal to 0.  x^{2} -2x=0.  Factor out an x, leaving us with  x(x-2)=0.  That means that x = 0 or x - 2 = 0 and x = 2.  Of course if we are solving for the length of a side we know it can't have a side length of 0, so it must have a side length that is a multiple of 2.  x = 2

(3/5) cubed Please explain to me how you would do this
krek1111 [17]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷  It would be done in the same way it would if it was an integer ;

think of it as two separate parts

(3/5)^3 = 3/5 * 3/5 * 3/5

Calculate the top half, then the bottom half and put them together

3 * 3 * 3 = 27

5 * 5 * 5 = 125

Thus, your answer will be 27/125

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

When given an algebraic expression involving subtraction, why is it best to rewrite the expression using addition before identif
Ray Of Light [21]
Usually when you do expressions involving subtraction you can do Keep, Change ,Change
That means you keep the sign of the first number and change the other two signs.
It is best you rewrite the expression to addition because a lot of people don't do well with subtracting .
