Answer:
6750
Step-by-step explanation:
simple interest = P×r%×t
P = $6000
r = 2.5%
t = 5 years
I = 6000 × 2.5/100 × 5
= 750
6000 + 750 = $6750
Answer:
x = 56.31%
Step-by-step explanation:
to find x, use 
x = 
x = 
x = 1.5
x = 56.3099
56.3099 = 56.31
S = 2b + ph
Lets subtract both sides by 2b
s - 2b = ph
Now, divide both sides by h
(s-2b)/h = p
Hope this helps!
Assuming you know the quadratic formula:

You can fill in a, b and c in this and get:

Now, let's create a shorthand
to make the writing easier:

But since one root is three times the other root (but we don't know which one), we also know that:
or 
If you solve this, you get:
or 
However, since q is a square root, it must be postive.
So we know that:

From this you find that

So p = 3/2
The roots are x=1/2 and x=3/2.
A unit circle has its center at the origin and has a radius of one. It is modeled by the equation
x² + y² = 1
We are given with <span>(x,-1)</span> .
Solving for x
x² + (-1)² = 1
x = 0<span />
