1)  I am not sure, but I think the constant of variation is the 3500 x I

         ANNUAL interest AMOUNT is   12/9 x 91.88 = 122.51

          The annual interest RATE is  122.51 / 3500 = .035    (which is 3.5 %)

         SO k would be   3500 (.035) = 122.51    and t would be the variable

2)  I = P(.035) t     The amount of simple interest is equal to the prinipal times the annual interest RATE  times  the  number of years

3)   the Annual interest is 122.51      122.51 x 5 = 612.55       

           Using our equation fro #2    I = 3500(.035)(5) = 612.50   ( slightly different due to rounding)

Apparently, dogs can't......

Kinda glad they don't....reminds me of an old 'poem' from many years ago

Birdie, Birdie in the sky....

Why'd you do that in my eye....

Aren't you glad that cows can't fly?

LOL

of course :)

You press 2nd and then the sin button.

You wrote  - (2/5)^2      this will result in   - 4/25       (I am not sure if that is what you meant   (-2/5)^2 = + 4/25)

soooooooo....

- 4/25 + 3(2/5)

-4/25 + 6/5

-4/25  +  30/25        ( I changed 6/5 to common denominator 30/25)

26 / 25   =  1 1/25

This just describes a right triangle (assuming the top is still 'connected' to the base....one leg is the base of 6 ft   and one leg is the distance of 12 feet    with the hypotenuse being the remaining height of the tree that must be added to the 6 foot base to get the height of the tree before it cracked and fell

Use pythagorean theorem....

a^2 + b^2 = c^2

6^2 + 12^2 = c^2

180 = c^2

c=sqrt(180) = 13.41    add this to the 6 foot base to get    19.41 feet tall before it broke.

"fat" is a way of looking at it , but has negative connotations.....more correctly the brain is 60 percent LIPIDS of a great number of chemical compositions  (various phospholipids cholesterol etc etc).....

the answer is 32.058 minutes

vf = vo + at        vo = original velocity = 0     a = acceleration of gravity   9.8m/s^2   or 32.2 ft/s^2  (I'll use 9.8 m / s^2)

                            vf = final velocity

vf = 0 + 9.8   m/s^2 (.0.5 s)  =  4.9 m/s     (do you see how one of the s cancels??)

Thats what I thought too, it was a test question and my sister got it wrong even after putting that as the answer, thanks for your help!

Since it is a SQUARE the area =  L x L    where L = lenght of a side

L x L = 200

L^2 = 200      take the sq root of both sides

L = sqrt(200) = 14.15 ft   to the nearest . 05

remember: the quadratic formula is -b plus or minus the square root of b^2 - 4ac all over 2a 

ax^2+bx+c=0

so 

[-9(+/-) sq root of (-9^2 -(4*1*20))] / 2*1

[-9(+/-) sq rt  (81-80)] / 2

[-9(+/-) sq rt of 1] / 2

[-9(+/-)1] / 2

then you do this for both + and -

(+)

(-9+1)/ 2

-4

 (-) 

(-9-1)/2

-5

so your answer is going to be -4 and -5

huh??  You have got the value      0-3+4= -3+4 = 4-3  = 1

0.5/80

\(\frac{0.5}{8}=\frac{5}{80}=\frac{1}{16}\)

It is usually quiker just to Google question like this :)

Distance   =  √[6^2 + 4^2]  = √[36 + 16]  = √52 =  2√13 ≈ 7.2 ft

thank you Hayley1

Mental math can only take you so far.
