615.44 = (3.14)(radius)^2 

<span>radius = square-root of (615.44/3.14) </span>

<span>diameter = radius x 2 </span>

<span>diameter = 28 inches

Find the tangents of the acute angles in the right triangle. Write each answer as a fraction. WILL MAKE BRAINLIEST!!
patriot [66]

Answers:

  • tan(G) = 2
  • tan(H) = 1/2

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

Explanation:

Recall that tangent is the ratio of opposite over adjacent

tan(angle) = opposite/adjacent

So for reference angle G, we say,

tan(G) = JH/GJ = 2/1 = 2

We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)

-----------

So we have this interesting property where

tan(G)*tan(H) = 2*(1/2) = 1

In general,

tan(A)*tan(B) = 1 if and only if A+B = 90 degrees

-----------

Side note: The side sqrt(5) isn't used at all.

Answer:

<u>Piece-Wise Function</u>

  • can have more than one type of function
  • holes can exist
  • to evaluate, look at the right side to determine which piece of the function to use

<u>Linear Function</u>

  • is written in standard form Ax + By = C
  • slope is the same for the entire graph
  • is written in slope-intercept form y=mx+b

Neither one of these always looks like a parabola.
