Find the equation of the line that passes through (-1,2) and is perpendicular to

Mathematics

Natalija [7]3 years ago
8 0

Answer:

Remember that the slope of perpendicular lines are negative reciprocals of each other.

Step-by-step explanation:

y = 1 - 2x     the slope is -2     the value of the x term.

So the slope of the new line using point (- 1, 2)  is  1/2.

Now use y = mx + b where y = -1, x = 2, and m = 1/2 .

y = mx + b

-1 = 1/2(2) + b                solve for "b", the y-intersect

-1 =  1 + b

-2 = b

The line that is perpendicular to y = 1 - 2x  is  y = 1/2x - 2

Find the surface area of the prism
Andrei [34K]
<h3>Answer:  168 square feet</h3>

=========================================================

Explanation:

The front triangular face is a triangle with base 8 and height 6. Its area is

A = 0.5*base*height

A = 0.5*8*6

A = 24 square feet

The back triangular face is also 24 square feet since these are the base faces of the prism. The base faces are always congruent. It might help to imagine this figure is turned on its side.

The slanted lateral face is a rectangle of length 10 ft and width 5 ft, so its area is L*W = 10*5 = 50 square feet

The rectangular face on the left is 6 ft by 5 ft giving an area of 6*5 = 30 square feet.

Lastly, the bottom rectangular face is 8 ft by 5 ft giving an area 8*5 = 40 square feet

Overall, the total surface area is: 24+24+50+30+40 = 168 square feet

We just add up all the individual areas of each face to get the total surface area.

How many triangles can you make with straws the lengths 2,1,2 inches
Yuliya22 [10]

Answer:

You can't make any triangle

Step-by-step explanation:

we know that

The T<u>riangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

so

In this problem

2+1>2

3>2 -----> is not true

therefore

You can't make any triangle.
