Answer:
Ann sold 124 bottles of drinks in the morning
Step-by-step explanation:
Let
x ---> bottles sold in the afternoon
y ---> bottles sold in the morning
we know that
Ann sold 314 bottles of drinks a day
so
-----> equation A
She sold 66 bottles more in the afternoon than in the morning
----> equation B
substitute equation B in equation A
solve for y
therefore
It is: (f(2) - f(0))/(2 - 0)
f(2) = 250(0.5)(2) = 250
f(0) = 250 (0.5)(0) = 0
So: (250 - 0)/(2 - 0) = 250/2 = 175
The average rate of change is 175.
By the Pythagorean Theorem
17^2=8^2+h^2
h^2=17^2-8^2
h^2=289-64
h^2=225
h=15 meters
