(I don't know what your question is, but if you're asking about the rate, I got it.)
Answer: 2.6666... meters per second
Explanation/Calculation:
Divide 40 by 15 to get the rate. You get 2 2/3 meters or 2.6666... meters per second.
Hope this helps! :)
Answer:
the domain of the function = [0,12]
Step-by-step explanation:
Given that:
f(t) = 60 t - 5t²
at time t = 0
f(0) = 60 (0) - 5(0)²
f(0) = 0
the differential of f(t) is:
f(t)' = 60 - 10t
for the maximum height
f'(t) = 0
i,e
60 - 10t = 0
60 = 10t
t = 60/10
t = 6
Now, t = 6,
f(6) = 60(6) - 5(6)²
f(6) = 360 - 180
f(6) = 180
Hence, after 6 seconds, the stone is noticed to have raise to 180 m and 180 m drop after 6 seconds.
Hence, the domain of the function = [0,12]
Answer:
(-5,1)
Step-by-step explanation:
y=3x+16
4x-5y=-25
substitute the given value of y into the equation.
4x-5(3x+16)=-25
solve
x=5
substitute the given value of x into the equation.
y=3x(-5)+16
solve
y=1
(-5,1)
Answer:
B. The line will fall faster as you move from left to right.
Step-by-step explanation:
As slope is decreased by 1, its shall fall much more quickly. The green line labels the line 
and red labels the line 
As the slope is decreased, the line will fall much more steeply.
