A right cylinder ice cream cone has 600 cubic centimeters of ice cream, what is the radius of the cone of the height is 15 centi
choli [55]
The formula for volume is V=Bh where  B is the area of the base. 
plug in what they have given you:
600=B(15) you can divide both sides by 15

40=B    We know that a cylinder's base is a circle so we can use the area f                           formula for a circle to solve for the radius.
40 = pi(r)^2   divide both sides by pi to get the r^2 alone
40/pi=r^2     square root both sides to get rid of the square
you should get
r=3.5 approximately

Kate has an interior decorating business. She charges a base fee of $25 for each visit and $40 per hour for her labor. 1) Write
nataly862011 [7]

Answer:

1) C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) Continuous

Step-by-step explanation:

1) The given parameters are;

The base fee charged = $25

The amount charged for labor = $40/hour

The total cost for h number of hours is C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) The situation is continuous because the different input values of h can be infinite (from o to infinity)

What is the equation of a horizontal line passing through the point (1, 14)?
Klio2033 [76]
The equation line passing through a point is understood to be parallel to the x-axis. In this case, the equation should be expressed as y = b where b is any number. Since y = 14 in the point (1,14), the equation of horizontal line passing through this point is y = 14.
