Answer:
3,052 cubic inches
Step-by-step explanation:
·· A beach ball has a spherical shape
·· Formula to calculate the volume of a sphere is given as:
In the question, we are given
Diameter = 18 inches
We have to find the radius
Radius = Diameter/2
Radius = 18 inches/2
Radius = 9 inches
The volume of the beach ball =
= 3,052.08 cubic inches
Approximately to the nearest whole number = 3,052 cubic inches
Answer:
With 20 visits in one year the cost of the clulbs are equal.
Step-by-step explanation:
On the club A the amount paid in function of the number of visits can be expressed as bellow:
cost = 60 + 2*visits
On the club B the amount paid in function of the number of visits can be expressed as:
cost = 20 + 4*visits
In order for the cost to be the same we must find a value of visits that makes them equal, so we have:
60 + 2*visits = 20 + 4*visits
2*visits - 4*visits = 20 - 60
-2*visits = -40
visits = 20
With 20 visits in one year the cost of the clulbs are equal.
Step-by-step explanation:
To find the derivative of
3x+5, apply sum rule

The derivative of

And

So we have

So the derivative of the function is 3,
Since linear equations have a constant slope, the slope at any point will be 3.
So the slope of the tangent line is 3.
Please consider looking over the steps I provide to enlighten your understanding on the concept. Thank you.

change the mixed fractions to improper ones:
3 1/5=
3*5=15+1
16/5
7 1/2=
7*2=14+1=15
15/2
Now we have the fractions 16/5 and 15/2, so convert these to decimals:
16/5=3.2
15/2=7.5
refine the equation:
p+3.2=7.5
subtract:
p+3.2-3.2=7.5-3.2
p=4.3
convert 4.3 to a fraction:
4.3=
4 3/10
21. Thus, p=4 3/10
