What is the total area of the regions between the curves y = 6x2 − 18x and y = −6x from x = 1 to x=3?.
kvasek [131]

Using integration, it is found that the area between the two curves is of 22 square units.

<h3>What is the area between two curves?</h3>

The area between two curves y = f(x) and y = g(x), in the interval from x = a to x = b, is given by:

A = \int_{x = a}^{x = b} |f(x) - g(x)| dx

In this problem, we have that:

f(x) = 6x^2 - 18x, g(x) = -6x, a = 1, b = 3.

Hence, the area is:

A = \int_{1}^3 |6x^2 - 12x| dx

A = |x^3 - 6x^2|_{x = 1}^{x = 3}

Applying the Fundamental Theorem of Calculus:

A = |3^3 - 54 - 1^3 + 6|

A = 22

The area between the two curves is of 22 square units.

Help please, id really appreciate it
Angelina_Jolie [31]

Answer:

Domain: [-2, 2]

Range: [-3, 3]

Step-by-step explanation:

Domain (x) is the left and right. Range (y) is the up and down.

It's a bracket if it is included, meaning, there is no gap or hole.

If it weren't included, it'd be a parentheses instead "( )". For example, if there was an open circle.

It would go to -infinty or +infinity if it were to go on forever, and that would be in parentheses.

EX: (-∞,∞) or (-∞, 8]

You can mix and match the brackets and parentheses depending on whether or not it touches/includes the number, like I've mentioned.

What is the value of z in the equation 2(2.5z − 58 + 43) = 176− 46? (3 points)
natali 33 [55]

Answer:

32

Step-by-step explanation:

2(2.5z − 58 + 43) = 176− 46

5z - 116 + 86 = 130

5z -30 = 130

5z = 160

z = 160/5

z = 32

Find an<br> equation for the line through (-6, 3) and<br> parallel to y = 3x + 1.
Anika [276]

Since this line is parallel to y = 3x + 1 their slopes are equal. The slope is equal to 3. The line is also passing the point (-3,4).

This is the format of the line parallel to y = 3x + 1

y = 3x+ b

This line passes through point (-3, 4)

Replacing the values of y and x coming from the coordinates of (-3, 4)

4 = 3 * (-3) + b

Solving for the y-intercept b

4 = -9 + b

b = 4 + 9

b = 13

Knowing the slope as equal to 3 and the y-intercept as 13 the equation of the line is

y = 3x+13
