Suppose you start a business assembling and selling motorized scooters. It costs you $1500 for tools and equipment to get starte
kvv77 [185]
Alright, so the money you make is automatically -1500 for the tools, so it's -1500. Next, the materials cost 200 dollars for each scooter, s, so we have -1500-200s. After that, we have 300 dollars for the sale of each scooter, so we have -1500-200s+300s. Adding -200 and 300 together, we have -1500+100s. To make a profit, that means 100s -1500 > 0. Dividing by 100, we have
s -15 >0  and s>15, so if you sold 16 scooters you'd make a profit. That profit would be 100*16-1500=1600-1500=100 dollars

Consider the following rational numbers -5.1 -5 1/3 -5 -5 3/5 list them in order from least to greatest
jok3333 [9.3K]

Answer:

-5.6, -5.3, -5.1, -5.

Step-by-step explanation:

Convert the first fraction to a decimal.

-5 1/3 is equal to -5.3333333333

Round to the nearest tenth.

-5.3333333333 rounded to the nearest tenth is -5.3.

<em>-5 1/3 = -5.3.</em>

<em />

Convert the second fraction to a decimal.

-5 3/5 is equal to -5.6.

The fraction is already rounded, so that's all for the second one.

<em>-5 3/5 = -5.6.</em>

<em />

The new set of numbers we have include -5.1, -5.3, -5, and -5.6.

We can now sort from least to greatest.

The first number is -5.6.

The second number is -5.3.

The third number is -5.1.

The fourth number is -5.

Listing the numbers -5.1, -5.3, -5, and -5.6 from least to greatest would result in -5.6, -5.3, -5.1, and finally -5.

A region R in the first quadrant of the xy-plane is bounded by the curves y = x², y = 2 - x and the x-axis. Find the value of th
lions [1.4K]

The two curves meet in the first quadrant when

x^2 = 2-x \implies x^2 + x - 2 = (x + 2) (x - 1) = 0 \implies x=1

Then the integral in question is

\displaystyle \iint_R x \, dA = \int_0^1 \int_{x^2}^{2-x} x \, dy \, dx \\\\ ~~~~~~~~ = \int_0^1 x (2-x-x^2) \, dx \\\\ ~~~~~~~~ = \int_0^1 (2x - x^2 - x^3) \, dx = 1 - \frac13 - \frac14 = \boxed{\frac5{12}}

Is the following relation a function?
dimulka [17.4K]

Answer:

yes

Step-by-step explanation:

A function is any graph that the x values do not repeat.

You can check this by using this vertical line test

Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.
