Answer:

<h2>C. None of the above</h2>

Step-by-step explanation:

$\text{The formula of a distance between x and y on a number line:}\\\\d=|b-a|=|a-b|\\\\\text{We have}\ a=\dfrac{5}{2}\ \text{and}\ b=4\dfrac{7}{8}.\ \text{The distance:}\\\\d=\left|\dfrac{5}{2}-4\dfrac{7}{8}\right|=\left|4\dfrac{7}{8}-\dfrac{5}{2}\right|}$

Evaluate the following integral, where R is bounded by , , and . Question content area bottom Part 1 enter your response here

Volgvan

$\iint_{R} y^{2} d A=\int_{x=-2}^{3} \int_{y=-x-2}^{3 x+6} y^{2} d x d y d x$

$\text { (taking Strip as shown). }$

$=\int_{-2}^{3}\left(\frac{y^{3}}{3}\right)_{-x-2}^{3 x+6} d x$

$=\frac{1}{3} \int_{-2}^{3}(3 x+6)^{3}-(-x-2)^{3} d x$

$\begin{gathered}=\frac{1}{3}[4375]=\frac{4375}{3} \\=1458.33\end{gathered}$

What is integral ?

Calculating an integral is called integration.
Mathematicians utilize integrals to determine a variety of useful quantities, including areas, volumes, displacement, etc.
When we discuss integrals, we often refer to definite integrals.
For antiderivatives, indefinite integrals are utilized.
Apart with differentiation, integration is one of the two main calculus subjects in mathematics (which measure the rate of change of any function with respect to its variables).
It's a broad subject that is covered in courses at the higher grade levels, such classes 11 and 12.
Broadly speaking, integration by parts and via substitution is explained.
You will discover the definition of integrals in mathematics, the integration formulae, and examples here.

$\huge \fbox \pink {A}\huge \fbox \green {n}\huge \fbox \blue {s}\huge \fbox \red {w}\huge \fbox \purple {e}\huge \fbox \orange {r}$

$\frac{42}{x} = \frac{5}{2} \\ x = \frac{5}{2} \times 42 \\ x = 5 \times \frac{42}{2} \\ x = 5 \times 21 \\ x = 105$

What is the first operation that you will perform when you evaluate this expression? 12 + (18 - 2) x 3 ÷ 24

Temka [501]

Answer:

(18-2)

Step-by-step explanation:

Use the formula of PEMDAS to determine which is first.

The p stands for parentheses so you would perform that operation first.

Lisa sold $75 worth of play tickets.Adult tickets cost $4 each and children’s ticket cost $4 each.How many children’s tickets co

Helga [31]

Yes, there are many possible answers. An equation that can model your situation is:
4a+4b=75, with a being the amount of adult tickets sold, and b being the amount of children’s tickets sold.
Because both tickets cost 4 dollars, you would multiply the amount of tickets sold, by the price (in dollars) of the ticket.
So, you can find possible answers by substituting the amount of adult tickets sold. Say, 4 adults bought tickets. You could then substitute a for 4. So the equation would look like this.
4(4)+4b=75
16 + 4b = 75
4b = 75 - 16
4b = 59
Divide each side by four
B = 14.75

The reason you got a decimal number is because 75 cannot be divided by 4 evenly. So, in this context, you could say that 15 children bought tickets. One child had an issue, and Lisa gave them a 25% discount. This would explain why there are only 75 dollars worth in tickets. I hope I helped, this is my first question I have ever answered so I’m not entirely sure if this was helpful or not. Hope you figure this out!
