If line GH is perpendicular to line HJ, then GJ is ____ HJ.

valentinak56 [21]

Option A: >

Solution:

Given a triangle GHJ.

The line GH is perpendicular to line HJ.

This means the triangle is a right angled triangle.

In ΔGHJ, GH is the base of the triangle and

HJ is a height of the triangle.

Then the third side must be the hypotenuse of the right triangle.

We know that by the Pythagoras theorem,

$(\text {Hypotenuse})^2=(\text{Base})^2+(\text{Height})^2$

$(\text {GJ})^2=(\text {GH})^2+(\text {HJ})^2$

This clearly shows that the hypotenuse is greater than the height.

⇒ GJ > HJ

Option A: > is the correct answer.

If line GH is perpendicular to line HJ, then GJ is > HJ.

The perimeter of the rectangle is 28 units.

avanturin [10]

The value of w is 5 units

Step-by-step explanation:

Let l be the length of the rectangle

and w be the width

Then

l = 2w - 1

$Perimeter = 2(l+w)\\28= 2(2w-1+w)\\28 =2(3w-1)\\28 = 6w -2\\28+2 =6w-2+2\\6w = 30$

Dividing both sides by 6

$\frac{6w}{6} = \frac{30}{6}\\w = 5$

Hence

The value of w is 5 units

Write an equation that models the sequence 400, 200, 100, 50, ...

Julli [10]

You're starting at 400. Each time you're cutting in half.

So the common ratio is 1/2 which means the equation is

$\Large y = 400(1/2)^{x-1}$

which is in the geometric sequence format. So the answer is choice D

You are graphing y < 2x + 1. What type of line do you use and where do you shade?

bazaltina [42]

Since there isn't a line under the < sign, this means that we used a dotted or dashed line. The dotted or dashed line indicates that we do NOT include the boundary as part of the solution set.

Since y is isolated and we have a less than sign, this means we shade below the dashed/dotted boundary line. Specifically, the boundary line is the graph of y = 2x+1. This boundary line goes through (0,1) and (1,3). Again, points on this boundary line are NOT part of the solution set.

So in summary we have:
A dashed or dotted boundary line
The shaded region is below the dashed/dotted boundary line.
