Answer:
total cost is $2444
Step-by-step explanation:
A company’s marginal cost function 
is where x is the number of units
Marginal cost function is the derivative of cost function
to find the total cost of producing units , take integral of marginal cost function
with intervals 144 to 625
now plug in the values
total cost is $2444
1,425 to 1000
and 19 to 20
i hope that helpped :)
Answer:
The height as a function of time is
h(t) = -(1/2)gt2 + v0t + h0
h(t) = -16t2 + 32t + 20
The ball reaches the ground when h(t) = 0
-16t2 + 32t + 20 = 0
Solve this quadratic equation for t. You will get a positive solution and a negative solution. Discard the negative solution, since time begins at t=0 at the moment the ball is struck. Can you finish from here?
C is false, not all whole numbers are natural, because 0 is considered a whole number but it is not a natural number.
Answer:
1570 meters
Step-by-step explanation:
The circumference of a circle is 2πr, so we would start by finding the radius. The radius is half of the diameter, so r=1/2(500)=250. We would then plug in numbers to the equation getting:
2(250)(3.14)
=500(3.14)
=1570 meters
