A college student is choosing between two data plans for her new cell phone. Both plans include an allowance of 2 gigabytes of data per month. The monthly cost of each option can be seen as a function and represented with an equation:
Option A: `A(x)=60`
Option B: `B(x)=10x+25`
In each function, the input, `x`, represents the gigabytes of data used over the monthly allowance.
Describe each data plan in words.
The functions for the total cost per month for data use are linear in each of the given options.
Correct responses;
1. A(1) = 60, B(1) = 35
2. A(7.5) = 60, B(7.5) = 100
3. The monthly charge for Option A fixed. The monthly charge for Option B includes a fixed monthly fee and $10 per gigabyte used.
4. Please find attached the combined graph of Option A and Option B. Option B is more affordable when the (extra) data usage is less than 3.5 gigabytes each month.
The amount of gigabytes of data the student would have for $50 is 2.5 gigabytes.
What is an expression?Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given parameters are;
Both plans data allowance per month = 2 gigabytes
The monthly cost for each option is;
Option A: A(x) = 60 = Constant
Option B: B(x) = 10·x + 25
Solution:
1. The values of A(1) and B(1) are;
A(1) = 60
B(1) = 10 × 1 + 25 = 35
Therefore;
A(1) = $60
B(1) = $35
2. The values of A(7.5), and B(7.5) are;
A(7.5) = 60
B(7.5) = 10 × 7.5 + 25 = 100
A(7.5) = $60
B(7.5) = $100
3. The description of each data plan are;
Option A
The data plan of option A has a fixed charge of $60
Option B
The charges on the data plan on option B consist of a fixed monthly charge of $25, and $10 per gigabyte of data used.
4. Please find attached the graph of the functions of Option A and Option B. From the graph, the most affordable plan to use based on the data usage is;
Option B; If the data used a month, x < 3.5 gigabytes
Option A; If the data used a month, x > 3.5 gigabytes
Either Option A or Option B if the data usage per month is exactly 3.5 gigabytes
The amount the student budgets per month = is $50
By using Option B, we have;
B(x) = 10·x + 25 = 50
10·x = 50 - 25 = 25
x = 25 / 10 = 2.5
At $50, the amount of gigabytes the student can get is x = 2.5 gigabytes

What 2 whole numbers is the square root of 75 between?
Answer:
8 and 9
Step-by-step explanation:
find the x-intercept and y -intercept 4x-7y=8
Answer:
x- intercept = 2, y- intercept = - \(\frac{8}{7}\)
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x
4x - 7(0) = 8 , that is
4x = 8 ( divide both sides by 2 )
x = 2 ← x- intercept
To find the y- intercept , let x = 0 in the equation and solve for y
4(0) - 7y = 8, that is
- 7y = 8 ( divide both sides by - 7 )
y = - \(\frac{8}{7}\) ← y- intercept

choose the expression that best completes this sentence: the function f(x) = ________________ has a local minimum at the point (8,0). a) x−8 b) (x−8)−1 c) x2−16x 64 d) −|x−8| e) (x−8)13
The correct answer to this question is option C: f(x) =\(x^2 - 16x + 64\). This is because the expression \(x^2 - 16x + 64\) can be factored as\((x - 8)^2,\) which represents a parabola that opens upwards and has its vertex at the point (8, 0).
The fact that the vertex is a minimum point can be seen by observing that the coefficient of \(x^2\) is positive, which means that the parabola opens upwards. In addition, the squared term in the expression \((x - 8)^2\)ensures that the function is symmetric around x = 8, which means that the vertex is the lowest point on the curve within some neighborhood of x = 8. Therefore, the function f(x) = \(x^2 - 16x + 64\)has a local minimum at the point (8,0).

I have 1,792 Pokémon cards, I also have 7 friends. I want to split the cards between me and the 7 of them. How many cards should each person get? Does the answer of this question has a remainder? Solve and Explain how you got your answer
We can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.
To split the 1,792 Pokémon cards equally between 8 people, including yourself and your 7 friends, you need to divide the total number of cards by the number of people:
1,792 cards ÷ 8 people = 224 cards per person.
So each person should get 224 Pokémon cards.
However, we should also check if there is a remainder after the division. To do that, we can multiply the number of cards each person is getting by the number of people and subtract it from the total number of cards:
224 cards/person x 8 people = 1,792 cards
1,792 cards - 1,792 cards = 0 remainder
Since there is no remainder, we can confirm that each person should receive exactly 224 Pokémon cards, and there won't be any cards left over.

A manufacturer produces two products, Product A and Product B. The weekly profit function, in dollars, is P(x,y)= 560x+20xy-20x2-6y2, where x and y are units of each product in thousands. Determine how many units of each product should be produced and sold weekly in order to maximize the manufacturer's total weekly profit and the maximum value of the total weekly profit. Follow the steps: (a) The only critical point of P is (XcY) =( (b) Use the D-Test to classify at the critical point whether the function has a relative maximum or minimum, or a saddle point, or inconclusive: At the critical point, the D value is ---Select--- , and the second order partial derivative Pxx is ---Select-- 1 . Therefore at this point --Select--- (c) Therefore in order to maximize the manufacturer's total weekly profit, week. units of Product A and units of Product B should be produced and sold per (d) Now, plug x = and y = into the function P(x,y) we obtain that the maximum weekly profit is $ Hint:
To maximize the manufacturer's total weekly profit, we need to find the critical point of the profit function P(x,y).
(a) To find the critical point, we need to find where the partial derivatives of P(x,y) are equal to zero.
Taking the partial derivative of P(x,y) with respect to x and y, we get:
P_x = 560 + 20y - 40x
P_y = 20x - 12y
Setting P_x = 0 and P_y = 0, we get:
560 + 20y - 40x = 0 and 20x - 12y = 0
Solving these equations simultaneously, we get:
x = 7 and y = 35
(b) To classify the critical point, we need to use the D-Test. The D value is:
D = P_xx * P_yy - (P_xy)^2
Substituting the values of P_xx, P_yy, and P_xy, we get:
D = -9600
Since D is negative, we have a saddle point at the critical point.
(c) To maximize the manufacturer's total weekly profit, we need to produce and sell 7,000 units of Product A and 35,000 units of Product B per week.
(d) Plugging x = 7 and y = 35 into the profit function P(x,y), we get:
P(7,35) = 560(7) + 20(7)(35) - 20(7)^2 - 6(35)^2
P(7,35) = $8,050
Therefore, the maximum weekly profit is $8,050.

a triangle has two sides of length 18 and 3. what is the largest possible whole-number length for the third side?
Answer:
20
Step-by-step explanation:
Triangle inequality says that the third side can only be 18-3...15, that is bigger than 15.
And 18+3... 21, that is smaller than 21.
If the third side is 21, the 18 and the 3 will just lay right on top of the 21 and not make a triangle. So it has to be 20 in order to be a whole number.

Answer:
Step-by-step explanation:
Bernie had $30 in his bank account.
Today he withdrew $d
Now he has = $30 — $d
Because from $30 he took away $d that’s why $d have to subtract from the $30.
Tomorrow he’ll deposit $15 and that will be added up with current balance $30 —$d.

The center is O. The circumference is 28. 6 centimeters. Use 3. 14 as an approximation for pi
The diameter of the given circle with a circumference of 28.6 centimeters is approximately 9.11 cm.
The circumference of a circle is given by the simple formula: C = πd, where C is the circumference, π is the constant pi and d is the diameter of the circle.
Given that the circumference of the circle is 28.6 cm, we can use the formula to find the diameter:
28.6 = πd
d = 28.6/π
Using 3.14 as an approximation for π, we get:
d ≈ 28.6/3.14 ≈ 9.11
