A concert-promoting company has been selling an average of 175 T-shirts at performances for $23 each. The company estimates that for each dollar that the price is lowered, an additional 25 shirts will be sold. Let x be the number of shirts sold. Find the demand function for the shirts.
Answers
The demand function for the shirts of a concert-promoting company which has been selling an average of 175 T-shirts at performances for $23 each is y=175-6.08x.
What is demand function?The demand function is the function
[tex]Q=a-bP[/tex]
Here, Q is linear demand curve, a factor which influence the demand, b is slope and P is price.
A concert-promoting company has been selling an average of 175 T-shirts at performances for $23 each. Thus, the total selling price is,
[tex]P=175\times23\\P=4025[/tex]
The company estimates that for each dollar that the price is lowered, an additional 25 shirts will be sold. Thus, the total number of
[tex]23=175-25b\\23-175=-25b\\b=\dfrac{152}{25}\\b=6.08[/tex]
Put the values in, the function for X number of shirt and y price,
[tex]y=175-6.08x[/tex]
Hence, the demand function for the shirts of a concert-promoting company which has been selling an average of 175 T-shirts at performances for $23 each is y=175-6.08x.

Alex is mowing a 145.5 square feet law. He used 3/4 gallon of as to mow 3/10 of the law. How many gallons of gas are needed to mow the entire lawn?
Answers
Answer:
2.5 gallons of gasStep-by-step explanation:
Note : we have a proportional relationship between the two variables
_______________________________________
He used 3/4 gallon of gas to mow 3/10 of the lawn
Then
He has to use 1/4 gallon of gas in order to mow 1/10 of the lawn
( we divided both sides by 3)
Then
He has to use 10 × 1/4 gallons of gas to mow 10/10 of the lawn
What that means is :
He has to use 10/4 gallons of gas to mow the entire lawn
In other words :
He has to use 2.5 gallons of gas to mow the entire lawn

The probability of picking a chocolate-covered cherry is 0.
The probability that an a fell on the floor is 0.08
The probability that an a or a o would be picked is 0.36
The probability a girl would be picked is 1.
What is the probability?
Probability is used to calculate the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of picking a chocolate-covered cherry is zero because there is no chocolate-covered cherry in the bag.
The probability that an a fell on the floor = number of a in the letter / total number of letters
= 1/13 = 0.08
The probability that an s or a o would be picked is = (number of s in the letter / total number of letters) + (number of 0 in the letter / total number of letters)
= 4/11 + 0 = 4/11 = 0.36
The probability a girl would be picked is one since its an all-girls school.

For the function f (x) = 4x - e determine
X such that f (x) 0
Answers
Answer:
derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the result is the slope of the original function y = f (x).
There are many different ways to indicate the operation of differentiation, also known as finding or taking the derivative. The choice of notation depends on the type of function being evaluated and upon personal preference.
Suppose you have a general function: y = f(x). All of the following notations can be read as "the derivative of y with respect to x" or less formally, "the derivative of the function."
f'(x) f' y' df/dx dy/dx d/dx [f(x)].
[HINT: don't read the last three terms as fractions, read them as an operation.
For example, read: " dx/dy = 3x"
As: "the function that gives the slope is equal to 3x"
Let's try some examples. Suppose we have the function : y = 4x3 + x2 + 3.
After applying the rules of differentiation, we end up with the following result:
dy/dx = 12x2 + 2x.
How do we interpret this? First, decide what part of the original function (y = 4x3 + x2 + 3) you are interested in. For example, suppose you would like to know the slope of y when the variable x takes on a value of 2. Substitute x = 2 into the function of the slope and solve:
dy/dx = 12 ( 2 )2 + 2 ( 2 ) = 48 + 4 = 52.
Therefore, we have found that when x = 2, the function y has a slope of + 52.
Now for the practical part. How do we actually determine the function of the slope? Almost all functions you will see in economics can be differentiated using a fairly short list of rules or formulas, which will be presented

Answers
Answer:
Step-by-step explanation:
Answer:
C^2 = 95 ft is the length of the hypotenuse.
Step-by-step explanation:
To get the hypotenuse, apply the Pythagorean theorem.
The formula is a^2+b^2=c^2, where a and b are the leg lenths and c is the length of the hypotenuse. This is referred to as the Pythagorean theorem.
We know what a and b are, so lets utilize the Pythagorean theorem
.
a^2 + b^2 = c^2 - This is the Pythagorean theorem formula.
76^2 + 57^2 = C^2 - Fill in the equation with a= 76 and b = 57^2.
5776 + 3249 = c^2
9025 = c^2 - C^2 is found by adding A^2 and B^2.
square root of c^2 = square root of 9025 - Take the square root of both sides of the equation.
C = 95 ft - Simplify
C^2 = 95 ft is the length of the hypotenuse. Brainliest? :D

Now , the value of A is
Let the number of cases ordered by Camp Copeland be = 20 cases
Let the number of eggs in each case = 12 eggs
So , the equation will be
The number of eggs in 20 cases A = 20 x number of eggs in each case
Substituting the values in the equation , we get
The number of eggs in 20 cases A = 20 x 12
The number of eggs in 20 cases A = 240 eggs
Therefore , the value of A is 240 eggs
Hence , the number of eggs is 240 eggs
