4*4=16

lmao ikr

Get a life noob

If you hate math then why are you on a math forum?

Find the final amount when £23000 is invested at 1.3% compound interest per month for 3 years.

FV = PV [ 1 + R]^N

FV =23,000[1 + 0.013/12]^3*12

FV =23,000 x 1.0397485

FV = 23,914.22 Pounds

P.S. I took 1.3% to mean annual rate compounded monthly. If you meant 1.3% to be a monthly rate for an annual rate of 15.6%,  then your final total will be =36,615.74 pounds.

well i love math this much: math999

(2m +1) 2 could be taken as 2m + 1 times 2 or 2m +1 to the power of 2 or "Squared" it depends on which. For the first you make a box. on the side you put 2 and on top you put 2m and +1. 2 times 2m = 4m, 2 times 1 = 2. so you get 4m + 2 and that is your simplified answer. For the other it would be 2m times 2m which = 4m(2) squared. +1 = 4m squared +1 as your simplified answer. Correct me if i'm wrong for the second one. :3 hope this helped

5.726 as a fraction equals 5726/1000

 f(x) = –2x2 + 12x + 5   factor out  the "-2"  on the right on the first two terms

f(x)  = -2 (x^2 - 6x)  + 5    take 1/2 of the coefficient on x (i.e., "-6"→ ( -3)^2  → 9)......square it and add an subtract it within the parentheses

f(x)   = -2(x^2 - 6x + 9 - 9) + 5   simplify

f(x) -2 ( x ^2 - 6x + 9)  + 18 + 5   factor the expression in the parenthese

f(x)   =  -2 (x - 3)^2 + 23

The vertex is  at (3, 23)......since there is a  "negative" in front of the first term, this is a maximum

C. Maximum at (3, 23)

The formula can be found at:  http://keisan.casio.com/exec/system/14059932254941

This also contains a calculator that applies it.

C. Maximum at (3, 23)

(50/300)x100%=1/6

5 · 3 - (-2 · -7)  =  15 - (14)  =  1

(-7 - 5) / (-2 · 3)  =  -12 / -6  =  2

5 / ( 3 · -2 - -7 )  =  5 / ( -6 + 7 )  =  5 / 1  =  5

-(-7) - ( 3 · -2 + 5 )  =  7 - ( -6 + 5 )  =  7 - (-1)  =  8
