In the rectagular prism shown below, GH is parallel to EF. If the equation of GH is 6y-x=2, could the equation of EF be 4=y-1/6x

ASHA 777 [7]

Answer:

Yes

Step-by-step explanation:

Given

GH:

$-6y - x = 2$

Required

Can EF be

$4 = y - \frac{1}{6}x$

First, we determine the slope of GH

$-6y - x = 2$

Solve for 6y

$6y = -x - 2$

Solve for y

$y = -\frac{1}{6}x - \frac{2}{6}$

$y = -\frac{1}{6}x - \frac{1}{3}$

An equation has the form:

$y =mx + b$

Where

$m = slope$

By comparison:

$m = -\frac{1}{6}$

Next, determine the slope of EF

$4 = y - \frac{1}{6}x$

Make y the subject

$y = -\frac{1}{6}x + 4$

The slope is:

$m = -\frac{1}{6}$

Compare the slopes of both lines.

$m=m = -\frac{1}{6}$

Since they have the same slopes, then the equation of EF is possible

The data in the table are linear. Use the table to find the slope.

Gemiola [76]

Answer:

$m = -\frac{3}{2}$

Step-by-step explanation:

Given

x 2 4 6 8

y 1 -2 -5 -8

Required

Determine the slope

First, pick any two corresponding x and y values.

$(x_1,y_1) =(2,1)$

$(x_2,y_2) =(8,-8)\\$

The slope (m) is then calculated using:

$m = \frac{y_1 - y_2}{x_1 - x_2}$

Substitute in, the x and y values

$m = \frac{1 - (-8)}{2- 8}$

$m = \frac{1 +8}{-6}$

$m = \frac{9}{-6}$

$m = -\frac{9}{6}$

Divide numerator and denominator by 3

$m = -\frac{9/3}{6/3}$

$m = -\frac{3}{2}$

<em>Hence, the slope is -3/2</em>

What is a formula to calculate the area of cross section when the figure is in circular shape

Naddik [55]

Answer:

Area for cross-section is 615.7521601cm

Step-by-step explanation:

area of a circle = πr²

π × radius²

In this question, the radius is 14, so you need to square it giving 196.

Then multiply by π = 615.7521601cm (round if necessary)
