Answer:
it looks like a positive correlation?
Step-by-step explanation:
I really don't know much but it looks like the y in increasing in a positive direction when the x is as well
Answer:
It solves all quadratic equations for any real or imaginary solutions.
Step-by-step explanation:
The quadratic formula is
.
It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions.
1. To find the sales tax rate you can set up the equation:
1200x = 72; divide both sides by 1200
x = 0.06
The tax rate is 6%.
2. 6% of 2500
0.06 x 2500 = $150
For Part A, the answer is d.
3. 6% of x is $108
0.06x = 108; divide both sides by 0.06
x = 1800
The answer for Part B is letter d.
Ladder=10 feet
bottom of ladder=4 feet
hight of tree=x
by using pythogorean theorem
h^2=altitude^2+altitude^2
10^2=4^2+x^2
100=16+x^2
84=x^2
taking sqrt on both sides
9.2=x
hope this helps
