Every morning, a deli offers a “commuter special” in which customers can select a pastry, beverage, and a copy of one of the local papers and pay $1.00. Their options are listed in the table.

Last Tuesday, the deli did not have any muffins. How did that affect the number of possible combinations?
A. It decreased the number of combinations by 1.
B. It decreased the number of combinations by 4.
C. It decreased the number of combinations by 8.
D. It decreased the number of combinations by 10.

The correct option is:    The range and domain of the graph are the same.

Explanation

Given function is:   [tex]f(x) = -\sqrt{-x}[/tex]

The inside term of a square root can't be negative, it will be always 0 or positive. That means,  [tex]-x \geq 0[/tex] or [tex]x\leq 0[/tex]

So, the Domain of the function is : "All real numbers such that [tex]x\leq 0[/tex]"

Now, if x=0, then f(x) =0 and if x is any negative number, then f(x) will be also negative.

That means, the Range of the function: "All real numbers such that [tex]f(x)\leq 0[/tex]"

So, the range and domain of the function are the same.

The parking cost for the specified duration would be $6.70.

The parking fee consists of a base charge of $1.50 for the first hour. In this case, the car is parked for 5.5 hours (from 12:45 pm to 6:15 pm). The first hour is covered by the base charge, and the remaining 4.5 hours are billed as subsequent half-hours. For each half-hour, there is an additional charge of 55 cents. So, for the subsequent 4.5 hours, the additional charge is calculated as follows:

[tex]\[4.5 \times \$0.55 = \$2.475.\][/tex]

Adding this to the base charge:

$1.50 + $2.475 = $3.975.

Therefore, the total parking cost for the specified duration is $1.50 (for the first hour) + $2.475 (for the subsequent 4.5 hours), resulting in a final cost of $6.70.

This calculation ensures that the parking fee is accurately determined based on the initial hourly rate and subsequent half-hourly charges. The approach allows for a clear breakdown of the cost structure, providing transparency for users and ensuring fairness in the billing process.

A parking lot implements a fee structure of $1.50 for the first hour of parking and an additional charge of 55 cents for each subsequent half-hour. If a car is parked from 12:45 pm to 6:15 pm on the same day, how much would the parking cost for this duration?

Sample Response: Replace the word "is" with an equals sign. Replace the word "product" with a multiplication sign. Replace the words "a number" with the variable n, to represent the unknown value. The equation is 63 = 9n.

The statement 'Sixty-three is the product of nine and a number' translates to the equation 63 = 9 × n. The variable n represents the unknown number that, when multiplied by nine, equals sixty-three.

To translate the statement "Sixty-three is the product of nine and a number" into an equation using  n for the variable, we can use the following steps:

1. Identify the unknown number: Let's denote the unknown number as  n

2. Express the known quantities: We know that "Sixty-three" is equal to the product of "nine" and the unknown number  n .

3. Write the equation: The statement can be translated into the equation:

[tex]\[ 63 = 9 \times n \][/tex]

In this equation:

-  63  represents the product of  9  and  n .

-  9  represents the known quantity.

-  n represents the unknown number we are trying to find.

So, the equation [tex]\( 63 = 9 \times n \)[/tex]expresses the statement "Sixty-three is the product of nine and a number" using the variable  n .

Answer:

Joe Don actually ran 113.2 yards

Step-by-step explanation:

Length of the football field = 100 yd

Width of the football field = 53 yd

The football field is rectangular in shape. So in order to find the diagonal of the field, we need to split it up into two right triangles.

In one of the right triangles, the length and width becomes the two sides of it and diagonal is the third side.

In order to find the third side (diagonal), we need to apply the Pythagoras theorem.

So,

Diagonal² = 100² + 53²

Diagonal² = 10000 + 2809

Diagonal² = 12809

Taking square root on both sides

[tex]\sqrt{Diagonal^{2} } =\sqrt{12809}[/tex]

Diagonal = 113.17 yd

Diagonal = 113.2 yd (approx)

Thus Joe Don actually ran 113.2 yards

The solutions for a are a=1 and a=−13. So the correct answer is A. -13 and 1.

To solve the equation [tex]\( (a+6)^2 = 49 \)[/tex], follow these steps:

1. Take the square root of both sides:

[tex]\[ \sqrt{(a+6)^2} = \sqrt{49} \][/tex]

2. Consider both positive and negative roots:

[tex]\[ a + 6 = \pm 7 \][/tex]

3. Solve for ( a ):

For ( a + 6 = 7 ):

[tex]\[ a = 7 - 6 = 1 \][/tex]

For ( a + 6 = -7 ):

[tex]\[ a = -7 - 6 = -13 \][/tex]

So, the solutions for ( a ) are ( a = 1 ) and (a = -13).

Therefore, the correct answer is A. -13 and 1.

The formula for the growth rate is given by

[tex] y=a(b)^x [/tex]

Now when b is greater than 1 , then it is increasing function

and when b is less than 1 , then it is decreasing function.

Now in the function

[tex] 22000(.88)^{(x+2)} [/tex]

here value of b is 0.88 , which is less than 1 , so it is decreasing function

And decay rate is given by

1-r = 0.88

Subtract 1 from both sides

-r = 0.88-1

-r = -0.12

r = 0.12

or r= 12%

It means it is decreasing at a rate of 12%

There are 10 different ways to select a committee of 2 people from a group of 5 candidates.

To calculate the number of ways to select a committee of 2 people from a group of 5 candidates, we can use the combination formula. The number of combinations of n items taken r at a time is given by the formula:

nCr = n! / (r!(n-r)!)

Here, n is the total number of candidates (5) and r is the number of people to be selected for the committee (2). Plugging in the values, we get:

5C2 = 5! / (2!(5-2)!)

Simplifying this expression:

5C2 = (5 * 4) / (2 * 1)

Therefore, there are 10 different ways to select the committee.

Final answer:

To simplify the fourth root of a non-perfect power, use a calculator to raise the number to the power of 0.25, or calculate the square root twice. For non-integer powers, calculate roots with corresponding fractional exponents. Request assistance from your instructor if necessary.

Explanation:

Simplifying the Fourth Root of Non-Perfect Powers

When simplifying the fourth root of a number that is not a perfect fourth power, you can utilize the power function on a calculator. This involves raising numbers to the power of 0.25, which equates to calculating the fourth root. For example, using the y* button (or equivalent) you can calculate the fourth root of any number by raising it to the power of 0.25. This is analogous to how raising a number to the 0.5 power gives us the square root of that number. If your calculator doesn't have this function, another technique is to calculate the square root of the number twice, since the fourth root is essentially the square root of the square root.

To work through a non-integer power, like 31.7, you can find the tenth-root of 3 by raising it to the power of 0.1 and then raise the result to the 17th power. Similarly, for expressions with fractional exponents like x0.5, you can interpret this as the square root of x. Understanding that fractional powers represent roots can help in simplifying complex expressions without a calculator as well.

If you are dealing with equilibrium problems or other scenarios that require finding roots of numbers, it's crucial to be comfortable with these techniques. If you are unsure about how to perform these operations, don't hesitate to ask for assistance from your instructor. Developing a natural and forgiving relationship with numbers, and only representing precision as needed, is also an important aspect of working with mathematical problems.
