How are the different representations of a function used to determine
the relationship between the quantities?
Answer:
Step-by-step explanation:
A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
A function can be represented algebraically. For example, 3x+6 3 x + 6 .
A function can be represented numerically.
A function can be represented graphically.
There are three ways in which representations of a function are used to determine are, algebraic, numerical, and graphical .
Given that,
To explain the way the representation of a function for the relationship between quantities.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
There are three ways in which the representations of a function are used to determine the relationship between the quantities,

Leila and Joe are two partners in a business. Leila makes $5 in profits for every $9 that
Jo makes. If Jo makes $36 profit on the first item they sell, how much profit does Leila
make?
Answer:
$20
Step-by-step explanation:
Leila to Jo: $5/$9
Leila to Jo: x/$36
5/9 = x/36
Cross multiply.
9x = 5 * 36
Divide both sides of the equation by 9.
x = 5 * 4
x = 20

5. What is the probability of rolling a 4 on a number
cube and pulling a red marble out of a bag that
contains 3 red, 2 black, and 5 yellow marbles?
The probability of rolling a 4 on a number cube and pulling a red marble out of the bag is 1/20.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
The probability of rolling a 4 on a number cube is 1/6, since there is one way to roll a 4 out of six possible outcomes (1, 2, 3, 4, 5, 6).
The probability of pulling a red marble out of the bag is 3/10, since there are three red marbles out of a total of ten marbles.
To find the probability of both events happening (rolling a 4 and pulling a red marble), we multiply the probabilities:
(1/6) x (3/10) = 1/20
Therefore, the probability of rolling a 4 on a number cube and pulling a red marble out of the bag is 1/20.

1. --- ---- 1500
4. payment. -400. 1100
14. payment. -250. 850
24. payment. -100. 750
Answer:
967.74
Step-by-step explanation:
The average daily balance of the credit card for the August 1 - August 31 billing period is $943.55.
What is the average daily balance?The average daily balance can be determined by dividing the total daily balaces for August by the number of days in August.
The average daily balance = total balance / total number of days in Augst.
Total balance = (1500 x 3 days) + (1100 x10 days) + (850 x 10 days) + (750 x 7 days)
Total balance = 4500 + 11,000 + 8,500 + 5,250 = 29,250
The average daily balance = 29250 / 31 = $943.55

A company has determined that its profit for a product can be described by a linear function.
The profit from the production and sale of 150 units is $455, and the profit from
250 units is $895.
(i) What is the average rate of change of the profit for this product when
between 150 and 250 units are sold?
(ii) Write the equation of the profit function for this product.
(iii) How many units give break-even for this product?
(b) You are the CEO for a lightweight compasses manufacturer. The demand
function for the lightweight compasses is given by p = 40 − 4q
2where q
is the number of lightweight compasses produced in millions.It costs the company $15
to make a lightweight compass.
(i) Write an equation giving profit as a function of the number of lightweight compasses
produced.
(ii) At the moment the company produces 2 million lightweight compasses and makes a profit
of $18,000,000, but you would like to reduce production. What smaller number of
lightweight compasses could the company produce to yield the same profit?
Step-by-step explanation:
(a)(i) The average rate of change is:
(895 − 455) / (250 − 150)
4.4
(a)(ii) Since the profit is linear, the slope of the line is equal to the average rate of change. Using point-slope form:
y − 455 = 4.4 (x − 150)
Simplifying to slope-intercept form:
y − 455 = 4.4x − 660
y = 4.4x − 205
(a)(iii) The break-even point is when the profit is 0.
0 = 4.4x − 205
4.4x = 205
x = 46.6
(b)(i) The "demand function" is the selling pice of the compasses:
p = 40 − 4q²
where p is the price in dollars and q is the quantity in millions of units.
Profit is revenue minus cost.
P = R − C
P = pq − 15q
P = (p − 15) q
P = (25 − 4q²) q
P = 25q − 4q³
where P is the profit in millions of dollars and q is the quantity in millions of units.
(b)(ii) Find values of q when P = 18.
18 = 25q − 4q³
4q³ − 25q + 18 = 0
We know that q=2 is a root of this equation. Using grouping:
4q³ − 8q² + 8q² − 25q + 18 = 0
4q² (q − 2) + (q − 2) (8q − 9) = 0
(q − 2) (4q² + 8q − 9) = 0
4q² + 8q − 9 = 0
Solve with quadratic formula.
x = [ -b ± √(b² − 4ac) ] / 2a
q = [ -8 ± √(8² − 4(4)(-9)) ] / 2(4)
q = (-8 ± √208) / 8
q = (-8 ± 4√13) / 8
q = (-2 ± √13) / 2
Since q is positive, q = (-2 + √13) / 2, or approximately 0.803.

Find the volume of a pyramid with a square base, where the perimeter of the base is 15.4 and the height of the pyramid is 13.1. Round your answer to the nearest tenth of a cubic meter.
The requried volume of the pyramid is 64.9 cubic meters.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
The first step is to find the area of the square base. Since the perimeter of the base is 15.4, each side of the square has a length of:
15.4 / 4 = 3.85
Therefore, the area of the base is:
A = (3.85)² = 14.8225 square meters
The volume of a pyramid is given by the formula:
V = (1/3) * A * h
where A is the area of the base and h is the height of the pyramid. Substituting the values given in the problem, we get:
V = (1/3) * 14.8225 * 13.1
V = 64.91925 cubic meters
Rounding to the nearest tenth of a cubic meter, we get:
V ≈ 64.9 cubic meters
Therefore, the volume of the pyramid is approximately 64.9 cubic meters.

b. Ferguson MATCHES 2. B= 0.48
c. Wilson MATCHES 4. D= +1.46
d. Crosby MATCHES 3. C= -1.00
Step-by-step explanation:
Given that;
their mean height u = 73.03
standard deviation α = 2.03
now the z-score height for each player;
a- Dustin Byfuglien (Winnipeg Jets) Height = 75
z = (x - u) / α = (75 - 73.03) / 2.03 = 1.97 / 2.03 = 0.9704 ≈ 0.97
b- Dylan Ferguson (Vegas Golden Knights) Height = 74
z = (x - u) / α = (74 - 73.03) / 2.03 = 0.97 / 2.03 = 0.4778 ≈ 0.48
- Tom Wilson (Washington Capitals) Height = 76
z = (x - u) / α = (76 - 73.03) / 2.03 = 2.97 / 2.03 = 1.4630 ≈ 1.46
Sidney Crosby (Pittsburgh Penguins) Height = 71
z = (x - u) / α = (71 - 73.03) / 2.03 = -2.03 / 2.03 = - 1.00
Therefore
a. Dustin MATCHES 1. A= 0.97
b. Ferguson MATCHES 2. B= 0.48
c. Wilson MATCHES 4. D= +1.46
d. Crosby MATCHES 3. C= -1.00
