Answer:
i think the answer is 2
Step-by-step explanation:
By the pythagorean theorem:
L^2=9^2+x^2
and we are told if:
L^2=(x+3)^2
L=x+3
L-3=x now using this in our first equation L^2=9^2+x^2 we get
L^2=9^2+(L-3)^2
L^2=81+L^2-6L+9
0=90-6L
6L=90
L=15 ft
You could write a set of equations or use the interest formula, A(t)=P(1+r/n)^nt
where p equals the principal amount, r equals the rate/ percentage of interest, n equals the compounding periods and t equals time
In a positive correlation, both variables increase together. An example of this is a company's profit's relationship with its sales. The greater the sales, the greater the profit.
A negative correlation is where one variable decreases with increase in the other. An example is the time taken to reach somewhere and the speed traveled at. The faster you move, the less the time.
No correlation means the two variables are not related. An example of this is as you get older, it does not mean you will get better grades.
It is either 17 or 151 i believe
