Jerry buys a new cell phone and signs up for a yearly cell phone plan. The cell phone costs $329 and the yearly plan costs 490 per year for every year he uses the cell phone. The only costs associated with the cell phone are the purchase price and the cost of the yearly cell phone plan.
a) Describe the annual cost of the cell phone per year as a function of the number of years he uses the cell phone.
b) What happens to the average price per year the longer Jerry holds onto this plan and explain why?
Answer:
(329 + 490X) / X = Cost
Thus, the average annual price decreases as the cell phone is used for more years, because the fixed cost (the cost of the value of the cell phone) is divided each time by a greater number of years.
Step-by-step explanation:
Since Jerry bought a new cell phone and signed up for a yearly cell phone plan, and the cell phone costed $ 329 and the yearly plan costs $ 490 per year for every year he uses the cell phone, to determine the annual cost of the cell phone per year as a function of the number of years he uses the cell phone, the following mathematical reasoning must be performed:
(329 + 490X) / X = Cost
So, for example, if the cell phone was used for 3 years, the function would apply as follows:
(329 + 490x3) / 3 = X
(329 + 1470) / 3 = X
1,799 / 3 = X
599.66 = X
Thus, the average annual price decreases as the cell phone is used for more years, because the fixed cost (the cost of the value of the cell phone) is divided each time by a greater number of years.

Find the values of X,Y and z
Answer:
x = 11.31
y = 13.86
z = 19.60
Step-by-step explanation:
8/x = x/16
x^2 = 128
x = 11.31
x^2 + 8^2 = y^2
128 + 64 = y^2 = 192
y = 13.86
x^2 + 16^2 = z^2
128 + 256 = z^2
z^2 = 384
z = 19.60

Y=-1|x-2|+1 how to solve
Answer:
if x ≥ 2, then y = x - 1
if x < 2, then y = -x + 3
Step-by-step explanation:
y = 1* |x - 2| + 1
y = |x-2| + 1
*** The rule on absolute value: |a| =a, if a ≥ 0; |a| = -a, if a < 0
If x-2 ≥ 0, then |x-2| = x-2, so y = (x - 2) + 1 = x - 1; y = x - 1
So if x ≥ 2, then y = x - 1
If x-2 < 0, then |x-2| = -(x-2) = -x + 2, so y = {-x + 2} + 1 = -x + 3; y = -x + 3
So if x < 2, then y = -x + 3

A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 666 centimeters per minute. After 202020 minutes, the water level is 220220220 centimeters.
Answer:
y = mx + b
slope(m) = 6
(20,220)....x = 20 and y = 220
now sub and find b, the y int
220 = 6(20) + b
220 = 120 + b
220 - 120 = b
100 = b
so ur equation is : y = 6x + 100
to graph :
y = 6x + 100.....u have a slope of 6....u have a y int of 100 or (0,100)...
I would say plot (0,100) and since ur slope is 6, go up 6 and to the right 1...but that is not to helpful because ur graph is not in intervals of 1.
So we will find some points on ur line.
y = 6x + 100....when x = 5
y = 6(5) + 100
y = 30 + 100
y = 130....so another point on ur line is (5,130)
y = 6x + 100...subbing in 10 for x
y = 6(10) + 100
y = 60 + 100
y = 160....another point is (10,160)
keep finding points this way...here are some more...
(15,190) , (20,220), (25,250)

the upper is 5 and the lower is 2
the highest is 8 lowestis 0
The median for b is 8
upper is 9 lower is 6
lowest is 0 highest is 10
It can't be a because they don't have the same median. Team A DOES have a lower median. It is not C. I really am thinking B

Find the circumference of the given circle
Use 3.14 as an approximation
7 in.
Answer:
Step-by-step explanation: Determine the radius of a circle. ...
Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm .
You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² .
The circumference of the given circle is approximately 43.96 inches.
Given that a circle with radius of 7 inches, we need to find the circumference of the circle,
We know that,
In the case of a circle, the circumference is the distance around the circle.
It is the total length of the curve that forms the boundary of the shape.
To find the circumference of a circle, you can use the formula:
Circumference = 2π × radius
The radius of the circle is 7 inches, and using the approximation of π as 3.14, we can substitute these values into the formula:
Circumference = 2 × 3.14 × 7
Circumference = 43.96 inches
Therefore, the circumference of the given circle is approximately 43.96 inches.

To graph the equation 2x + 5y = 10, Zeplyn draws a line through the points (5, 0) and (0, What is the slope of the line represented by 2x + 5y = 10?
Answer: -2/5
Step-by-step explanation:
To find the slope, we set the function use y = mx + b forms.
2x + 5y = 10
5y = -2x + 10 Minus 2x in both side
y = -2/5x + 10/5 Divide 5 from both side
y = -2/5x + 2
In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.

Nikki brought a patio set on sale for $480 the original price was 850 what is the rate of discount
Answer:
43.5%
Step-by-step explanation:
Substitute the original price of $850 and the sale price of $480 to find
amount of discount=850−480=370
Use the amount of discount, $370, to find the discount rate. Use the equation
amount of discount=discount rate×original price.
Rearrange the equation to solve for the unknown value.
discount rate=amount of discountoriginal price
Substitute in the known values and solve to find the discount rate.
370850=0.435=43.5%
Thus, the discount rate on the patio set was 43.5%.
