Answer:

6 pi

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

The diameter is 2 so the radius is 1/2 d = 1

V = pi (1)^2 * 6

V = 6 pi

The required equation of line parallel to given line is: $y = \frac{5}{6}x-8$

Step-by-step explanation:

Given equation of line is:

$y = \frac{5}{6}x+1$

As the equation of line is in slope-intercept form, the co-efficient of x s the slope

Let m1 be the slope of given line

m1= 5/6

Let m2 be the slope of new line

As the slopes of two parllel lines are equal, so

m1 = m2

m2 = 5/6

The slope intercept form is:

$y= m_2x+b$

Put m2 = 5/6 in equation

$y = \frac{5}{6}x+b$

Putting the point in the equation

$2 = \frac{5}{6}(12)+b\\2=10+b\\b = 2-10\\b = -8$

Putting the value of b, we get

$y = \frac{5}{6}x-8$

Hence,

The required equation of line parallel to given line is: $y = \frac{5}{6}x-8$

Answer:

Mid-point: $(0,-5)$

Equation: $y=\frac{7}{3}x-5$

Step-by-step explanation:

To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.

$(\frac{{x__A}+{x__B}}{2},\frac{{y__A}+{y__B}}{2})$

$(\frac{{-7}+{7}}{2},\frac{{-2}+{(-8)}}{2})$

$(0,-5)$

To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.

Slope of AB: $\frac{{y__2}-{y__1}}{{x__2}-{x__1}}$ = $\frac{{-8}-{-2)}}{{7}-{(-7)}}$ = $\frac{-6}{14}$ = $\frac{-3}{7}$

Multiplying slopes that are perpendicular with each other always results in -1.

$\frac{-3}{7}*m = -1$

$m=\frac{7}{3}$

By the point slope form:

$({y}-{y__1})=m({x}-{x__1})$

Plug in the coordinates of the mid-point:

$({y}-{(-5)})=\frac{7}{3} ({x}-{0})$

Equation: $y=\frac{7}{3}x-5$

7 out of 28 is what percent?

jeka57 [31]

Here's what I did and I checked it So it is correct!!

$\frac{7}{28} = \frac{1}{4}$

$\frac{1}{4} = 0.25$

25% is your answer.

$28 \times 25\% = 7$

Help on question 11. A) please

lana [24]

They didn't follow PEMDAS. according to pemdas, exponents come first (since there are no parentheses here), so they were right to simplify 4^2 to 16. However, multiplication and division come before addition and subtraction, which means they should have multiplied 5 by 3 and then subtracted the product from 16.

So, the work really should have shown 16-15=1.
