astraxan [27]

Answer:

Step-by-step explanation:

Using the Cofunction identity

sin(90 - x)° = cos x°, hence

cos80° = sin(90 - 80)° = sin10° → C

Answer:

Step-by-step explanation:

The common ratio can be < 0

All that means is the entry's signs alternate.

For example

r = - 2

a = 3

Series = 3 -6 18 -54 etc. The members of the series become larger and larger in magnitude and the series diverges. It is not clear where it might stop.

-1 < r < 0 gives a much better behaved result.

The point is that c is incorrect.

In the deli where Tran works, a customer ordered 0.25 pound of cheese. When Tran puts the cheese slices on the scale, they weigh

Alex

And inequality is written to compare two quantities.

The best way to show how these two quantities compare would be to put is zero to the right of the five in 0.25. Make it 0.250.

Please see the attached picture for two correct ways to write this inequality.

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
