Step-by-step explanation:
if f (x) = 100 - x;
as x increases, the value of f(x) will decrease
What are the following fractions
profit=f(x)
so solve for f(x)=1000
1000=70n-400
add 400 to both sides
1400=70n
divide both sides by 70
20=n
20 students need to be enrolled to make a profit of 1000.00
Answer:
x ≈ 13.5
Step-by-step explanation:
Using the sine rule in the triangle, then
=
( cross- multiply )
x × sin27° = 11 × sin34° ( divide both sides by sin27° )
x =
≈ 13.5 ( to the nearest tenth )
