F(x) means "function of" and x represents the day number, example: day 6 would be f(6)=(20×6)+95
Answer:
D) 16
Step-by-step explanation:
The fifth term of the geometric sequence would be 0.972
Answer:
In Right Δ ABC with right angle B,
∠A=(3 x -8)°, ∠B=90°, ∠C=(x-2)°
∠A+∠B+∠C=180°[∠ sum property of triangle]
3 x-8+90 + x-2=180
Adding and subtracting like terms
4 x-10+90=180
4 x+80=180
4 x=180-80
4 x=100
x=100/4
x=25°
∠A=3×25-8=75-8=67°
