If a right triangle is rotated around the longest leg what three-dimensional figure is formed

A bike rental company charges a fee per hour. The charge, in dollars, is the same each hour. The ordered pairs (3, 13.50) and (5

If the function is y = 4.5x. Then the rate of change of the function expressed as a unit rate will be 4.5.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bike rental company charges a fee per hour.

The charge, in dollars, is the same each hour.

The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.

Then the linear equation is given as

$\begin{aligned} \rm y - 22.5 &= \rm \dfrac{22.5 - 13.5}{5 - 3} (x- 5)\\\\\rm y - 22.5 &= \rm 4.5x - 22.5\\\\\rm y &= \rm 4.5x \end$

Then the rate of change of the function expressed as a unit rate will be

$\rm \dfrac{dy}{dx} = \dfrac{d}{dx} (4.5x )\\\\\dfrac{dy}{dx} = 4.5$

Y-7=2y (x-1) write the equation in standard form

Hunter-Best [27]

In order for an equation to be in standard form, the equation has to be in Ax+By=c form, where A is equal to the coefficient of x and B is equal to the coefficient of y, whereas c is just the constant, or the number in the equation that isn't being multiplied to a variable. In this case, you should first distribute 2y into (x-1), and then you should perform inverse operations on terms on both sides of the equation such that one side of the equation will only have terms with x and y in them and the other side of the equation will only be a numerical value. When the equation is like this, then the equation is in standard form.

Which expression could be a calculator’s display for the number 0.00000000000096?

Zina [86]

=> 50 x 100 = 5000 <span>Expression of calculator’s display for this given number:
0.00000000000096

How to get this answer.
Since it’s a decimal number, I am pretty sure that the number will be negative.
Now, let’s move the decimal points to the right.
=> Thus the answer is c. 9.6e-13
Because, from the decimal point, we move to the right 13 times, and since it’s decimal, it’s negative. So the answer is 9.6e – 13
e represents to the number of zeros.</span>
