Answer:
232.96
Step-by-step explanation:
18.2-12.8=5.4
12.8•12.8=163.84
5.4•12.8=69.12
163.84+69.12=232.96
There is no difference. Both mean the same measurement except that 1.050 is presented in 4 significant figure and 1.05 in 3 significant figure.
Answer:
$100 * (1 + 6.8%/12)^216 + $100*(1+6.8%/12)^215 + ... + $100*(1+6.8%/12)^1
Now note that
x + x^2 + x^3 + ... + x^N = x ( 1 + x + ... + x^(N-1) )
= x ( (x^N -1)/(x-1) )
Here, x = 1+6.8%1 = 1.00566666 and N = 216, so
$100 * ( 1.00566666 ( 1.00566666^216 -1) / 0.00566666 )
= $ 42398.33
The total interest earned is $42,398 - $21,600 = $20,798
Step-by-step explanation:
The generic formula used in this compound interest calculator is V = P(1+r/n)^(nt)
V = the future value of the investment
P = the principal investment amount
r = the annual interest rate
n = the number of times that interest is compounded per year
t = the number of years the money is invested for
Nothing, goes into 49 and 50.
What is the Pythagorean Theorem?
The PyTheorem states that -- actually, why not just simplify things and make it a formula?

where a and b are legs of a triangle and c is the hypotenuse of a triangle.
It is only true applying to right triangles.
Now what are the legs of a triangle?
The sides that are NOT opposite the 90 degree angle!
Now, all you have to do is find the LENGTHS of the three triangles!
Rise over run, remember?
Let's take the triangle in the top right of the coordinate plane for example.
A=(1,1)
B=(4,4)
unnamed point=(4,1)
Rise, or length of unnamed point to B?
(4,1) to (4,4)
(x,y), remember!
So? 4-1=3!
Run, or length of unnamed point to A?
(1,1) to (4,1)
Remember (x,y)?
So, 4-1=3!
The triangle has legs of 3 and 3.
Square em and add!
9+9=18




That's for length of AB!!
Now do the same for the remaining lengths!
Hope this helps!
