9 1/16=16*9+1=145

145/16*48=145*3=435

You are very welcome!

:P

I think this is

(-1)^[ cos(-pi) ]

Note that we have a trig identity that says    cos(theta) =  cos(-theta)

So....  cos (pi)  = cos(-pi)  = -1

So

(-1)^[cos(-pi)]  =

(-1)^{ -1 ]  =

1 / - 1  =

-1

I put in    1000 / (1+9e^(-.4 *15))  

Thanks soooooo much, guest!!!!!

FV=P{[1 + R]^N - 1/ R}, where FV=Future Value, P=Periodic Payment, R=Rate of interest, N=Number of periods.
FV=100 x {[1 + 0.09/12]^(10*12) - 1 / (0.09/12)}
FV=100 x {[1.0075]^120 - 1 / (0.0075)}
FV=100 x {[2.4513570 - 1] /(0.0075)}
FV=100 x {[1.4513570] / (0.0075)}
FV=100 x {193.5142770...}
FV=19,351.43 - Pounds.
Note: This is what you would have at the end of 10 years or 120 months if deposits are made at the END of each month @ 9% compounded monthly. If the deposits are made at the BEGINNING of each month, then you would have:
19,351.43 x 1.0075 =19,496.56 - Pounds

Note that the two triangles are both right triangles with legs of 3 and 4.....so....he hypotenuse is

sqrt (3^2 + 4^2) =  sqrt (25) = 5

And this is the length of the sides

And we have a rectangle with bottom/top of 8 units

So....the permeter is  2(5) + 2(8)  + 2(4)= 10 + 16 + 8 =  34 cm

Here's as much of the answer as I know :

YES!!.

Thanks, guest!

So for #3, the point of maximum growth would be 1000 right?

Use your formula above and plug in 15 for t as follows:

P(t) = 1000/(1 + 9 e^(-(0.4×15)))

       = 1000/(1 + 9* e^-6)

       = 1000/(1 + 9* 0.00247875....)

       = 1000/(1 + 0.022308767)

       = 1000/(1.022308767)

       = 978.178

That's alright... I appreciate you doing your best to help

im sorry this is to advanced for me.

thank you
