There is neither a direct variation nor inverse variation between the values in the table. There is actually no relationship between the x and y values.

The height, h, of the equilateral triangle is given by h =5cotΘ, where Θ is 30 degrees. Can someone help me with this? I don't u

Hoochie [10]

You don't even need the picture to solve this one.

You said that h = 5 cot(Θ) , and you said that Θ is 30 degrees.
All you need now is to find the cotangent of Θ, plop that into the equation,
and the solution practically jumps off the paper into your lap.

To find the cotangent of 30 degrees, you can use a calculator, look it up
in a book, read it off of a slide rule if you have one, draw a picture of a
30-60-90 right triangle etc. You'll find that the cotangent of 30 degrees
is √3 . That's about 1.732 .

So your equation is h = 5 (1.732) = 8.66 (rounded)

Apparently, somebody gave you the equation, and asked you to find 'h'.
Once you had the equation, you didn't even need to know that 'h' has
anything to do with a triangle.

1,000 darts were thrown at the rectangular board shown here. If 159 darts hit the circle, which of the following is most likely

Ludmilka [50]

The probability would be $\frac{159}{1000}$ ,
Simplify and turn into ratio.
0.159 : 1.

I am unsure what the full question was though.

Hope this helps.

Evaluate this function: For f(x) = -2x + 9, find f(5)

saul85 [17]

f(5) is -1

Step-by-step explanation:

Step 1: Given f(x) = -2x + 9, find f(5)

f(5) = -2 × 5 + 9 = -10 + 9 = -1
