Without knowing the number of pieces that the pizzas were cut into, it is not possible to determine the fraction of a whole pizza that is left.

Step-by-step explanation:

Therefore, the range of the function is all real numbers except for 0. In interval notation, this can be written as (-∞, 0) U (0, ∞).

In mathematics, a function is a relation between two sets, where each element in the first set (called the domain) is associated with exactly one element in the second set (called the range). Formally, a function f from a set A to a set B is a rule that assigns to each element a in A a unique element b in B, denoted by f(a). The set A is called the domain of the function, and the set B is called the range.

Here,

The given function is y = x/(8-x).

To find the range of this function, we need to determine the possible values of y for all possible values of x.

First, we note that the function is undefined when the denominator (8-x) equals zero. Therefore, x cannot be equal to 8.

Next, we consider the behavior of the function as x approaches positive infinity and negative infinity.

As x approaches positive infinity, the value of y approaches zero. This is because the x term in the numerator grows much more slowly than the 8-x term in the denominator, causing the overall value of the function to approach zero.

As x approaches negative infinity, the value of y approaches negative infinity. This is because the x term in the numerator becomes very negative while the 8-x term in the denominator approaches 8, causing the overall value of the function to become very negative.

Answer:

y = x + 6

Step-by-step explanation:

We can put the equation of the line in slope intercept form [tex]y=mx+b[/tex] where m is the slope and b is the y intercept.

The line passes through (0,6) which means that is our y intercept. Now we have to count the slope. To do this, we can either evaluate the slope given 2 points or count it if given a graph. We have a graph, so the convenient thing to do is to count it. If we count, we see that our slope is [tex]\frac{1}{1}[/tex] or simply 1. All we have to do now is write it in slope intercept form.

The value of r'(1) = 60 for the given function, using the chain rule.

By adding the derivatives of f(x) with regard to g(x) and g(x) with respect to the variable x, one may get the derivative of the composite function h(x) = f(g(x)). The chain rule of differentiation can be used to derive derivatives of composite functions. Now, let's go over what composite functions are. When a function is expressed in terms of another function, it is said to have a composite function. This suggests that a function can be changed into another function in a composite function.

Using the chain rule of derivatives we have:

r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)

Substituting the values we have:

r'(1) = f'(g(h(1))) * g'(h(1)) * h'(1)

r'(1) = f'(g(3)) * g'(3) * 3

r'(1) = f'(4) * 4 * 3

r'(1) = 5 * 4 * 3

r'(1) = 60

Hence, the value of r'(1) = 60 for the given function, using the chain rule.

Monique needs to invest $50,354.37 today to have $500,000 in 30 years at an annual interest rate of 7.8% compounded half-yearly. Option D

We can use the formula for future value of an annuity to solve this problem:

FV = P * [(1 + r/n)^(n*t) - 1]/(r/n)

Where:

FV = future value (desired amount) = $500,000

P = the amount invested today

r = annual interest rate = 7.8%

n = number of compounding periods per year = 2 (half-yearly)

t = number of years = 30

Substituting the values:

$500,000 = P * [(1 + 0.078/2)^(2*30) - 1]/(0.078/2)

Solving for P using a financial calculator or an online TVM calculator, we get:

P = $50,354.37

Therefore, Monique needs to invest $50,354.37 today to have $500,000 in 30 years at an annual interest rate of 7.8% compounded half-yearly.

4). Assume that the container weighs "x" and the honey weighs "y."

We are aware that a 1000 g container of honey weighs in total.

So Equation 1 is x + y = 1000 g

We can calculate the overall weight to be 600g by using half of the honey.

Equation 2: x + (y/2) = 600 g

y/2=600 - x

y= 2 (600 - x)

y= 1200 - 2x

We can replace “y” with 1200 - 2x in Equation 1:

The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

All real numbers are thought to be adequately explained by the four basic operations, sometimes known as "arithmetic operations." The mathematical operations quotient, product, sum, and difference come after division, multiplication, addition, and subtraction.

1. We are given that it costs $300 plus $55 per person attending to host an event.

Let the number of attendees be x.

We get the expression as 300 + 55x.

2. We are given that 30 people are attending the event.

So, substituting x = 30 in the expression, we get

⇒ Total cost = 300 + (55 * 30)

⇒ Total cost = 300 + 1650

⇒ Total cost = $1950

Now, using the division operation, we get

⇒ Per person charge = 1950 ÷ 30
