The concrete company charges $130 for delivering less than yd Superscript 3 of concrete. For yd Superscript 3 and more, the charge is $/yd Superscript 3 with a fraction of a yard charged as a fraction of $.65 Use function notation to write the charge as a function of the number x of cubic yards delivered, where 0x10, and graph this function. Question content area bottom Part 1 Choose the correct function below.

Answer 1

Answer:

Answer:

Step-by-step explanation:

To write the charge as a function of the number of cubic yards delivered, we can define two separate cases:

Case 1: For deliveries less than yd³, the charge is a flat fee of $130.

Case 2: For deliveries of yd³ or more, the charge is $/³, where a fraction of a yard is charged as a fraction of $0.65.

Let's use function notation to write the charge as a function of the number of cubic yards delivered, where 0 ≤ ≤ 10.

The function can be written as:

() =

\begin{cases}

130 & \text{if } < \\

0.65(-) + \frac{}{} & \text{if } ≥ \\

\end{cases}

Here, () represents the charge for cubic yards delivered, and is the threshold value in cubic yards where the charge changes.

To graph this function, we can plot points on a coordinate plane by choosing different values for and . The resulting graph will have two parts: a flat line representing the flat fee of $130 for < , and a linear line representing the variable charge of $/ for ≥ . The point where these two lines meet will be the threshold value (, 130).

The quotient of 5/31 divided by 15/23, reduced to the lowest fraction, is A. 93/23 or 4 1/23.
B. 75/373.
C. 115/465.
D. 23/93.

Answers

When you want to get the quotient of two fractions you would cross multiply them.
(5/31)/(15/23) would become ((5x23)/(31x15))= (465/115) you could then simpy the top and bottom by 5 ending up with (93/23) you can simply that into a mixed fraction by dividing 23 into 93 is 4 times with 92 so the whole number is 4 and 93-92 = 1. so the numerator of the fraction is 1 and 93 remains the denominator. so the answer could also be 4(1/93).

Use graphs and tables to find the limit and identify any vertical asymptotes of limit of 1 divided by the quantity x minus 3 as x approaches 3 from the left.

Step-by-step explanation:

If we graph the function, we can see that as we approach 3 from the left, we go towards negative infinity.

∴ $\displaystyle \lim_( \to 3^-) (1)/(x - 3) = -\infty$
