Answer:
Option A.
Step-by-step explanation:
Based on the information provided on the question
the function used to model Tony's run is:
f(x) = -250*x + 5000
This means that after x = 20 minutes, Tony will arrive to the finish line
f(20) = -250*(20) + 5000 = -5000 + 5000 = 0
The function is always decreasing, because we are dealing with a line with negative slope.
Option A.
Solution
Using trigonometry,
sin(¤) = length of side opposite of the angle÷length of the hypotenuse.
sin(45) = x/52.3
x = 52.3×sin(45)
Answer
x = 36.98 cm
F(x)= 3/16x to the third power - 9/4x + 3
Answer:
13/20
Step-by-step explanation:

Hoped this helped.
Y=-8x+240
look honestly im not sure if this is correct but its worth a shot
