------------------------------------------------------------------
Let the number be x.

------------------------------------------------------------------
Construct Equation:
------------------------------------------------------------------
x ÷ (-10) = -30

------------------------------------------------------------------
Multiply for (-10) on both sides:
------------------------------------------------------------------
x = (-30) x (-10) = 300

And the cross-section perpendicular to the yaxis is a square. Set up a definite integral expressing the volume of the solid

zheka24 [161]

The volume of the cross-section perpendicular to the solid is the amount of space in the cross-section

<h3>How to set up the integral?</h3>

The question is incomplete;

So, I will give a general explanation on how to set up a definite integral for volume of a solid

Assume the solid is a cone;

Using the disk method, the integral of the volume is:

$V = \int\limits^a_b {\pi r(x)^2} \, dx$

Using the washer method, the integral of the volume is:

$V = \int\limits^a_b {\pi [R(x)^2 -r(x)^2 ]} \, dx$

Question 4(Multiple Choice Worth 2 points)

laiz [17]

Answer:

The coefficient of variable term y is -1

Step-by-step explanation:

We have an expression given in the question that is:

6 - y + 3

We have to find the coefficient of the variable term.

In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.

Coefficients are the number the multiply the variable

For example

In 2x, x is the variable and 2 is the coefficient.

Now in the given expression, we have

6 - y + 3

6 + (-1)(y) + 3

So considering (-1)(y), the variable is y while its coefficent is -1
