Answer:

Step-by-step explanation:

Friday receipts:  [tex]235 \times 12[/tex]

Saturday receipts: [tex]260 \times 12[/tex]

Total [tex]=235 \times 12 + 260 \times 12[/tex]

         [tex]=12(235+260)[/tex]     (since 12 is a common factor in both expressions)

To find the total receipts in dollars for the two performances, you need to multiply the number of tickets sold by the price per ticket. The formula is: total receipts = (number of tickets sold) x (price per ticket). Based on this formula, which expression do you think is correct?

The correct expression would be: 12(235+260)

You can check your answer by simplifying the expression: 12(235+260) = 12(495) = 5940. The total receipts in dollars for the two performances are $5940.

A)
i) the inequality to show the number of ballons that the dance committee can buy is: 0.80b + 65 ≤ 125

ii)  solving the inequality above, we arrive at b ≤ 75
B) The graph is attached accordingly.

C) See the description of the solution below.

Let's start by defining our variables. Let b be the number of balloons that the dance committee could buy.

The cost of b balloons is $0.80b. We want to make sure that the cost of the balloons plus the amount already spent on decorations ($65) is less than or equal to the budget of $125. So we can write the following inequality:

0.80b + 65 ≤ 125

Now we can solve for b:

0.80b + 65 ≤ 125

0.80b ≤ 125 - 65

0.80b ≤ 60

b ≤ 75

Therefore, the dance committee can buy up to 75 balloons to stay within their budget.

To graph the solution set, we can plot b on the horizontal axis and shade the region to the left of b = 75, since b must be less than or equal to 75.

The solution set represents all possible values of b that satisfy the inequality. In this case, the solution set is b ≤ 75, which means that the dance committee can buy up to 75 balloons and still stay within their budget.

As the number of balloons increases, the cost of the balloons also increases, and the amount of money left in the budget decreases.

Therefore, the more balloons the dance committee buys, the less money they will have left for other decorations or expenses.

The phrase "hardest colour to hold" from Robert Frost's poem "Nothing Gold Can Stay," is the line that the poet uses to best encapsulate his  thoughtfulness and sadness. The Option A is correct

These lines convey a message that goodness and beauty are transient and challenging to cling onto. As the reader considers the fleeting nature of life and the transitory nature of the things we hold dear, this concept may cause them to feel melancholy and reflective.

Although phrases such as "just so an hour," "early leaf's a flower," and "first green is gold" also emphasized an impermanence and fleetingness, but the phrase "hardest colour to hold" makes this point the most strongly.

Answer: a. To shift the graph of f(x) downward 5 units, we subtract 5 from the function: f(x) - 5. To shift it left 3 units, we replace x with x + 3: f(x + 3) - 5. To stretch it vertically by a factor of 4, we multiply the entire function by 4: 4[f(x + 3) - 5]. Finally, to reflect it about the x-axis, we take the negative of the function: -4[f(x + 3) - 5]. Therefore, the equation of the new function g(x) is:

g(x) = -4[1/2^(x+3) - 5]

b. To find the y-intercept, we set x = 0 in the equation of g(x):

g(0) = -4[1/2^(0+3) - 5] = -4[1/8 - 5] = -4[-39/8] = 195/2

Therefore, the y-intercept is (0, 195/2).

c. The domain of g(x) is all real numbers, since there are no restrictions on x.

d. To find the range of g(x), we first observe that the function is decreasing and asymptotic to y = -5 as x approaches infinity. This means that the range of g(x) is all real numbers less than or equal to -5.

In response to the question, we may say that  Hence, 2 131/200 is the decimal mixed number in its most basic form.

The decimal number system is frequently used to express both integer and non-integer quantities. Non-integer values have been added to the Hindu-Arabic numeral system. The technique used to represent numbers in the decimal system is known as decimal notation. A decimal number consists of both a whole number and a fractional number. The numerical value of complete and partially whole quantities is expressed using decimal numbers, which are in between integers. The full number and the fractional part of a decimal number are separated by a decimal point. The decimal point is the little dot that appears between whole numbers and fractions. An example of a decimal number is 25.5.

We must separate the whole number and fraction components of 2.655 in order to change it into a mixed number. The integer portion of the decimal, which is 2 in this instance, represents the full number.

We take the total number and divide it by the decimal to determine the fractional portion.

2.655 - 2 = 0.655

The combined number is therefore 2 and 655/1000.

By dividing the numerator and denominator by their largest common factor, we may reduce the fraction to its simplest form and so make it easier to understand. The highest common factor between 655 and 1000 in this instance is 5.

655 ÷ 5 = 131

1000 ÷ 5 = 200

Hence, 2 131/200 is the mixed number in its most basic form.

Answer:

g(f(-3)) = 6.

Step-by-step explanation:

To obtain the value of f(-3), we must first determine g(f(-3)), which requires changing x in the expression for f(x) to -3:

f(x) = 2x^2 + 9x - 1

f(-3) = 2(-3)^2 + 9(-3) (-3) - 1\s= 2(9) (9) - 27 - 1\s= 18 - 27 - 1\s= -10

Knowing that f(-3) = -10 allows us to replace it in the expression for g(x):

g(x) = -x - 4

g(f(-3)) = g(-10) (-10)

Now, if we replace x in g(x) with -10, we obtain:

g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6

Hence, g(f(-3)) = 6.

Answer:

g(f(-3))=6

Step-by-step explanation:

To calculate g(f(-3)), we must first determine the value of f(-3), and then we must insert that value into g(x) to obtain the result.

By adding x = -3 to the formula for f(x), we may obtain f(-3).

f(-3) = 2(-3)

² + 9(-3) - 1

f(-3) = 2(9) - 27 - 1

f(-3) = 18 - 28

f(-3) = -10

Knowing that f(-3) = -10 allows us to replace it in the formula for g(x):

g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6

Hence, g(f(-3)) = 6.

To find the probability of an advertising firm selected at random having under $1 million or $1 million to $20 million in income after taxes, we need to add the number of firms in each of these two categories and divide the result by the total number of firms.

Number of firms with under $1 million in income after taxes = 95

Number of firms with $1 million to $20 million in income after taxes = 74

Total number of firms = 95 + 74 + 31 = 200

Therefore, the probability of an advertising firm selected at random having under $1 million or $1 million to $20 million in income after taxes is:

(95 + 74) / 200 = 0.845

What is a relative extremum?

A relative extremum is a relative minimum or maximum of a function.

Since the function F(x) = 2ax² + bx + 3 has a relative extremum at the point (-1,2). This implies that dF(x)/dx = 0 at the extremum.

So, F(x) = 2ax² + bx + 3

dF(x)/dx = d(2ax² + bx + 3)/dx

= d2ax²/dx + dbx/dx + d3/dx

= 4ax + b

dF(x)/dx = 0

⇒ 4ax + b = 0

⇒b = -4ax at x = -1

b = -4a(-1)

= 4a

Since the function F(x) = 2ax² + bx + 3 has a relative extremum at the point (-1,2), we have that

F(-1) = 2a(-1)² + b(-1) + 3
