The parent function of a graph is f(x) = x2. The graph shifts a units to the left and down b units. Which function models the transformed function?
A) y = x2 - a + b
B) y = (x - a)2 - b
C) y = (x + a)2 - b
D) y = (x - b)2 - a
Answer:
Option c
Step-by-step explanation:
A parent function is given by f(x) = x²
If the graph of the parent quadratic function is shifted a units to the left then new function will become
f'(x) = (x+a)²
Now the new function f'(n) is shifted b units down then the shifted function will be
f" (x) = (x + a)² - b
Therefore, Option c. is the answer.
A local civic group is selling t-shirts to raise funds for Relay to Life. They plan to sell
2500 t-shirts for $10. They consider raising the t-shirt price in order to earn more
profit. For each $1 increase, they will sell 100 fewer t-shirts. Let x represent the
number of $1 increases.
a. Write a function,
Write a function, c(x), to represent the cost of one t-shirt based on the number
of increases.
b. Write a function, t(x), to represent the number of t-shirts sold based on the
number of increases.
c. Write a revenue function, r(x), for the t-shirt sell that could be used to maximize
a. Let us say that c(x) is the cost of one t shirt based on the number of increases therefore:
c = 10 + x
b. Say that t(x) is the number of t shirts sold based on the number of increases so:
t = 2500 – 100 x
b. The revenue is simply the product:
r(x) = (10 + x) (2500 – 100 x)
Combining:
r(x) = 25000 – 1000 x + 2500 x – 100 x^2
r(x) = 25000 + 1500 x – 100 x^2
Taking the 1st derivative and setting dr / dx = 0 to get the maxima:
dr / dx = 1500 – 200 x
1500 = 200 x
x = 7.5
t = 2500 – 100 x = 2500 – 100 (7.5) = 1750
Hence 1750 shirts should be sold.

The pitch of the roof is the number of feet the roof rises for each 12 feet horizontally. If a roof has a pitch of 8. What is its slope expressed as a positive number? What does the slope mean in this story?
The slope of the roof, expressed as a positive number, is 0.67. This represents the steepness of a roof, with a higher number indicating a steeper roof. The figure is calculated using the rise over run ratio.
Explanation:The pitch of a roof is a number that expresses how much the roof's height changes for every 12 feet you move along horizontally. If a roof has a pitch of 8, it means that for every 12 feet you move horizontally, the height of the roof increases by 8 feet. This gives us a rise/run ratio, which is how slope is defined in mathematical terms.
In this case, the rise is 8 feet, and the run is 12 feet. So, the slope would be 8/12, or 0.67 when expressed as a positive decimal number.
The slope here represents the steepness of the roof. A higher slope means a steeper roof and vice versa. By expressing the slope as a number, we can get an idea of how steep the roof is without having to see it in person.

Three friends were born in consecutive years. The some of their birth years is 5982.find the year in which each person was born
Answer:
The birth years of first person is 1993.
The birth years of second person is 1994.
The birth years of third person is 1995.
Step-by-step explanation:
Three friends were born in consecutive years
Let the birth years of first person be x,
Let the birth years of second person be (x+1)
Let the birth years of third person be(x+2)
The sum of their birth years is 5982.
[tex]x+(x+1)=(x+2)=5982[/tex]
Solving the given equation for x:
[tex]3x+3=5982[/tex]
[tex]x=\frac{5982-3}{3}=1993[/tex]
The birth years of first person = x = 1993
The birth years of second person = (x+1) = 1993+ 1 = 1994
The birth years of third person = (x+2) = 1993+2 = 1995
Pqr is a right angle. If pq=8 what is equivalent
The steps to do it. It says "solve for x. Each figure is a parallelogram. Show your work.
The value of x is 4.
To solve for x, we'll use the property of parallelograms that opposite angles are supplementary.
Given that one angle is [tex]\(140^\circ\)[/tex], we can set up the equation:
140 + 10x = 180
Now let's solve for x:
10x = 180 - 140
10x = 40
[tex]x = \frac{40}{10}[/tex]
x = 4
Therefore, the value of x is 4. Adjacent angles in a parallelogram are indeed supplementary.

Consider the equation below. f(x) = 4x3 + 6x2 − 24x + 3 (a) find the intervals on which f is increasing. (enter your answer using interval notation.)
The function f(x) = 4x^3 + 6x^2 - 24x + 3 is increasing on the interval (-2/3, 1.5), where the derivative of the function is positive.
Explanation:To find the intervals on which the function f(x) = 4x^3 + 6x^2 − 24x + 3 is increasing, we first need to calculate its derivative, which will give us the slope of the tangent line to the function at any point x. The function is increasing wherever its derivative is positive.
The derivative of f with respect to x is:
f'(x) = 12x^2 + 12x - 24.
To find where the function is increasing, set the derivative greater than zero:
12x^2 + 12x - 24 > 0
Solve this inequality to find the intervals for x. Factoring the quadratic, we get:
(2x - 3)(6x + 4) > 0
The zeros of this equation are x = 1.5 and x = -2/3. These values divide the real number line into intervals. Test a value from each interval to see where the function is increasing:
If x < -2/3, for example x = -1, the derivative becomes negative, indicating the function is decreasing.If -2/3 < x < 1.5, for example x = 0, the derivative is positive, indicating the function is increasing.If x > 1.5, for example x = 2, the derivative is again negative, indicating the function is decreasing.Thus, the function f(x) is increasing in the interval (-2/3, 1.5).

A hockey team played 81 games in a season. they won one fewer games than three times the number of ties, and lost eight fewer games than they won. how many games did they win? lose? tie?
Final answer:
The hockey team won 38 games, lost 30 games, and tied 13 games in the season.
Explanation:
Let's define the variables for the different outcomes in the hockey team's season:
T = number of games tiedW = number of games won = 3T - 1L = number of games lost = W - 8The total number of games is the sum of wins, losses, and ties, and we know this number is 81. This gives us the equation:
W + L + T = 81
Substituting W and L gives:
(3T - 1) + (3T - 1 - 8) + T = 81
Combining like terms and solving for T:
7T - 10 = 81
7T = 91
T = 13 (number of ties)
We then calculate W and L as:
W = 3T - 1 = 3(13) - 1 = 38 (number of wins)
L = W - 8 = 38 - 8 = 30 (number of losses)

A car travels 416 miles in 8 hours and at this rate how many miles will the car travel in 22 hours
To find out how many miles the car will travel in 22 hours, we calculate the unit rate by dividing 416 miles by 8 hours to get 52 miles per hour and then multiply this unit rate by 22 hours to get 1144 miles
The question involves calculating the distance a car will travel at a given rate over a different period of time. This is a basic rate problem in math, often approached by finding the unit rate and then scaling it to the desired time.
Step 1: Identify the rate of travel. The car travels 416 miles in 8 hours.
Step 2: Find the unit rate by dividing the distance by the time. Unit rate = 416 miles / 8 hours = 52 miles per hour.
Step 3: Calculate the distance the car will travel in 22 hours using the unit rate. Distance = 52 miles/hour * 22 hours = 1144 miles.
So, at this rate, the car will travel 1144 miles in 22 hours
