What is the amplitude of the function graphed?

Looks like it would be 2 since the amplitude to the peak is 3, but the amplitude to the trough is 1. So u add both together to get 4 and divide by 2 and you end up with 2.

Arlo invested $4000 in an account that earns 5.5% interest compounded annually the formula for compound interest interest is A (
Alika [10]
For compounding interests, we use the equation F = P (1+i)^n where F is the future amount of the principal amount, P, in n years. Take note that the interest to be used should be the effective interest rate. In this case, it is already the effective interest rate.

F = P (1+i)^n
F = $4000 (1+.055)^4
F = $4955.2986

A=pir^2 solve for pi
VashaNatasha [74]

Given problem;

   A = \pi r²

   Solve for π;

To solve for π implies that we make it the subject of the expression.

So;

       A = π r²

      Now multiply both sides by \frac{1}{r^{2} }

 So;

                A x \frac{1}{r^{2} }   = \pi x r² x \frac{1}{r^{2} }

              r² cancels out from the right side and leaves only π;

                  π = \frac{A}{r^{2} }

So    \pi  = \frac{A}{r^{2} }

Multiply 3i(−1 + 2i). What is the simplified version written in standard form, a + bi, where a and b are real numbers?
Sholpan [36]
3i (- 1 + 2i)     Remove the brackets.
3i (-1) + (2i)(3i) Look at the first set of brackets around the -1
-3i + 6i^2     But i^2 = - 1[ I hope that's the way you are using it]
-3i - 6 or -6 - 3i or -3(2 - i) <<<<< answer
