Add them all up.
A triangle has 3 sides, and you said each side is 3. So:
3+3+3 = 9

The perimeter of a the triangle measuring 3 on each side is 9. cause you can do 3+3+3 and it is 9 or you can do 3x3 and still get 9 either way it is 9 XD

The graph of f (0) = -4 cos 0 is shown below. The range of this function is
Anika [276]

Answer:

-4 ≤ f (\theta) ≤ 4

Step-by-step explanation:

The range of a function is the allowed y-values of the function.

We can simply look at the periodic function below and see that the y-value ranges from a negative 4 to a positive 4. It oscillates betwen -4 and 4. That is the range.

We can say -4 ≤ f (\theta) ≤ 4

Last answer choice is right.

*** <u>NOTE:</u> it is a type, not "0", rather "\theta"

Rx+9/5=h solve for x
Vika [28.1K]
When solving the equation, you first have h- 9/5. So it would by x=(h - 9/5). But you are not done yet. you still have to divide it by R to get x. So the final equation is x=(h - 9/5) ÷ R

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.
