(2,3) so x=2, y=3 and h=(2^2+3^2)^(1/2)=√13
sina=3/√13, cosa=2/√13, tana=3/2
Afterwards multiply sina and cosa by √13/√13 and get sina=(3√13)/13 and cosa=(2√13)/13

Answer:
M>3.50
Step-by-step explanation:
14×.25=3.5
As she bought more, M>3.50 is appropriate.
Step-by-step explanation:
If x + 7 is a factor of f(x), then f(-7) = 0.
f(-7) = (-7)³ − 3(-7)² + 2(-7) − 8
f(-7) = -343 − 147 − 14 − 8
f(-7) = -512
x + 7 is not a factor of f(x).
