1.Write an equation of the line in point-slope

Oduvanchick [21]

Answer:

Point slope form

$y-10 = -6 (x+1)$

Slope-intercept form

$y=-6x+4$

Standard form

$4x+y=4$

Step-by-step explanation:

Equation in Point slope form is

$y-y_1=m (x-x_1)$ ---------- (1)

Here

$m=-5 \ \ \ and \ \ \ (x_1, y_1) = (-1, 10)$

Substituting values in equation (1)

$y-10 = -6 (x+1)$ ------------- (2)

Equation (2) is equation of line in point slope form.

Re-arranging equation (2)

$y = -6x - 6 + 10$

$y=-6x+4$ ----------- (3)

Equation (3) is equation of straight line in slope-intercept form

Re-arranging equation (3)

$4x+y=4$ --------(4)

Equation (4) is equation of line in standard form

A rectangle has an area of 63 square inches. The width of the rectangle is 6 inches. What is the rectangle’s length, in inches?

atroni [7]

When you know the area and one side of a rectangle, divide the area by the known side to find the length of the other side.

Length = 63/6

Length = 10.5 inches

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.

hichkok12 [17]

Answer:

$2\pi(e^2-e^{-4})$

Step-by-step explanation:

We are given: $f(x)=2e^x$

So, the integral will be used to calculate the volume.

$V = \pi\int\limits^1_{-2}(2e^x)^2dx=\pi\int\limits^1_{-2}4e^{2x}dx=2\pi e^{2x}|^1_{-2} =2\pi(e^2-e^{-4})$

What is the measure of angle A?

fgiga [73]

Answer:

∠A=65º

Step-by-step explanation:

A angle of a line is 180º, so we can say that angle ABC=(180-6x)º
The interior angkes of a triangle is 180º, so (x+40)º+(3x+10)º+(180-6x)º=180º
Remove parenthesis, x+40+3x+10+180-6x=180
Combine like terms, -2x+230=180
Subtract 180, -2x=-50
Divide by -2, so x=25

Now:

∠CAB=(25+40)º=65º
∠ABC=[180-6(25)]º=30º
∠BCA=[3(25)+10]=85º
