Let us assume that we can write the function as :

f(x)  = a^x

And notice that we have :

.36  = a²      (1)

And

.1296  = a⁴    (2)

Divide (2) by (1)

.1296 / .36  =  a⁴ / a²

0.36  = a²        take the positive square root of both sides

0.6  = a

So.....our function is

f(x)   = a^x   = 0.6^x

Adding onto rainstraw1195's answer, radian and degree modes usually come into play affect the answer you get for trig functions such as sin or cos.

How did you get that?

But How Did You Get That?

Well...THAT's a horse of a different color from the original question (I assume you) posted

fv=pv (1.05)^8 = 8864.73

Suppose that 6,000 is invested in an account at 5% intrest. Find the account balance after 8 years of compound interest.

FV=PV[1 + R]^N

FV=$6,000 [1.05]^8

FV=$6,000 x 1.4774554437890625

FV=$8,864.73

Just key the decimal in and hit enter......it should show you the rational result

Yah,  I knew that.......  

FV = PV e^rt      where r= rate in decimal expression   t= time   (This is for continuous compounding)

6000 e^ (.05)8= 8950.95

1-The first investment would be worth=$2,634.60 after 18 months @ 6% comp. monthly.

2-The second investment would be worth=$2,632.39 after 18 months @ 6% comp.monthly.

So, the difference between the two is almost negligible, or: $2,634.60 - $2,632.39=$2.21.

P.S. The formulas I used should be in your textbook. If you have any questions, just let us know.

Thanks, EP.....I was reading that decimal point as a comma in the original prob......!!!!

[ I need to get these glasses checked  !!!   ]

I'd suggest they walk (crawl?) faster or they will get smacked.....but really, just how much speed can a car have on a road that is only 12 feet LONG????

(13/6) / (x/y)   = (2/3)       multiply both sides by (x/y)

(13/6) = (2/3) (x/y)       divide both sides by (2/3)

(13/6) / (2/3)   = (x/y)

(13/6) * (3/2)  = x/y

39/12   = x/y  = 13/4

So  x =  13,  y = 4

Chris for got his decimal point    f(x) = . 6^x

13/4    or any  factor thereof

Here's a possibility :

f(x)  = 6^x

Its how much times the outer line of a circle is 'bigger' than the diameter...... ITS HARD TO EXPLAIN SEARCH IT ON THE INTERNET!!!

My calc teacher(s) would be unhappy too....likely they are turning over in their graves !        Thanx Chris...     LOL

-7/8 + (-1/2) GCD of 2 and 8 is 8

-7/8 + -4/8 = -11/8= -1 3/8

We'll need to know the dimensions of Roy's kitchen floor to answer this....and those are some really BIG tiles !!

Mmmmm........let's see.....   3 minutes ???

V=4/3.pi.r^3

7,776pi=4/3.pi.r^3 divide both sides by pi.4/3

5,832=r^3 take the cube root of both sides

r=18 inches-the radius of the sphere.

My Calc I  teacher would not have been happy with you for leaving out that constant, ElectricPavlov......LOL!!!!!

[She used to mark the whole thing wrong if you did that......believe me......I never made that mistake twice ]

It means radian, and will measure in Radians rather than degrees.
