F(x)= -6(-1)+9
F(x)= 6+9
The answer is 15
Answer:
Step-by-step explanation:
Divide the numbers
12+153⋅6−412+153⋅x6−412+315⋅x6−412+56−412+5x6−4 12+5x6−4
1. You have the following information:
-The annual interest rate <span>is 7.2%.
- The </span><span>simple interest is calculated quarterly.
2. Then, to solve this exercise and calculate the </span><span>periodic interest rate of Marta's Account, you only have to divide the annual interest rate (7.2%) by 1/4 year. So, you have:
</span>
=(7.2%)(1/4)
=(7.2%)/4
=1.8%
<span>What is the periodic interest rate of Marta's Account?
The answer is: </span>1.8%
According to the questions statements it shows
y= L sin (theta)
and as it shows A and B are right triangle
y= sqrt (L^2 - x^2)
we need to find the speed of B by differentiating w.r.t time.
so,
d/dt = dx/dt . d/dx = -v d/dx
-v represents the A's velocity
so,
Vb = d/dt (y) = -v d/dx sqrt(L^2-x^2)
= v.x/ sqrt(L^2-x^2)
x/ sqrt(L^2-x^2) = cot (theta)
hence
Vb = vcot (theta)
