For maximum security I would advise you to add capital letters
The compound interest formula is:
F = P * (1+i) ^ (n*t)
where:
F = future value
P = present value
i = r/n ; r = interest rate, n = number of times interest is compounded per year
t = number of years
Substituting:
F = 800 * ( 1 + .032/1 ) ^ (1*15) ; n=1 since compounded annually
F = 800 * ( 1 + 0.032) ^ (15)
F = 800 * ( 1.032) ^ 15
F = 800 * ( 1.60396711263693 )
F = 1283.17369010954
So there will be $1283.174 in the account.
a counterclockwise rotation about the origin of 90°
The coordinates of P(3, 3), Q(5, 3), R(5, 7)
The coordinates of P'(- 3, 3 ), Q'(- 3, 5), R'(- 7, 5)
Note that the y-coordinate of the image is the negative of the original, while the x-coordinate of the original becomes the y-coordinate of the image
The rotation which does this is a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x )
Answer:
first you simplify the first part which will be
(15)^2-(18+9)*(6)
225-27*6
225-162
Answer will be 63
