What is the measure of 3?
mafiozo [28]

Answer:

∠3 = 60°

Step-by-step explanation:

Since g and h are parallel lines then

∠1 and ∠2 are same side interior angles and are supplementary, hence

4x + 36 +3x - 3 = 180

7x + 33 = 180 ( subtract 33 from both sides )

7x = 147 ( divide both sides by 7 )

x = 21

Thus ∠2 = (3 × 21) - 3 = 63 - 3 = 60°

∠ 2 and ∠3 are alternate angles and congruent, hence

∠3 = 60°

Arithmetic Sequence.<br><br>What is the explicit formula for -39, -139, -139, -339?​
creativ13 [48]

Answer:

  an = -39 -100(n -1)

Step-by-step explanation:

The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...

  -39, -139, -239, -339

This has a first term a1 = -39, and a common difference d = -100.

The model for the explicit formula is ...

  an = a1 +d(n -1)

Filling in the given values, the formula you seek is ...

  an = -39 -100(n -1)

_____

* That polynomial is ...

  an = 50n^3 +350n^2 -800n +461

This gives a sequence that starts ...

  -39, -139, -139, -339, -1039, -2539, -5139, -9139, ...

hyperbola with center at (0,0) with x intercepts at (4,0) and (-4,0) with b= 1 , opening horizontally equation
Tanya [424]
Check the picture below.

now, if the x-intercepts are at ±4 whilst the center is at the origin, that means the vertices are the ones hitting the x-axis, like in the picture, so just plug in the values for a, b, h and k.
