Answer:

(x, y, z) = (74, 37, 25)
all acute angles are 74°
all obtuse angles are 106°

Step-by-step explanation:

The usual rules at an intersection of lines apply:

vertical angles are congruent
linear pairs are supplementary

In addition, where a transversal crosses parallel lines, ...

corresponding angles are congruent

This means, in effect, for this geometry where parallel lines cross parallel lines, all acute angles have the same measure, all obtuse angles have the same measure, and the obtuse angles are supplementary to the acute angles.

x° = 180° -106° = 74° . . . . . . x and 106 are supplementary

2y° = x° . . . . . . . . . . . . . . x and 2y are corresponding

y = 74/2 = 37 . . . substitute for x, divide by 2

(4z +6)° = 106° . . . . . . obtuse angles are congruent

4z = 100 . . . subtract 6

z = 100/4 = 25

The variable values are ...

x = 74
y = 37
z = 25

All obtuse angles are 106°; all acute angles are 74°.

"Which of the following are continuous functions? (Select all that apply.)

Natasha2012 [34]

Answer:

□ The temperature at a specific location as a function of time.

□ The temperature at a specific time as a function of the distance due west from New York City.

□ The altitude above sea level as a function of the distance due west from New York City.

Step-by-step explanation:

Temperature tends to vary continuously over distance and time.

Altitude rarely changes so abruptly we'd have to say it is a discontinuous function. Even a cliff has a (very high) defined slope.

Taxi charges tend to increment according to a rate schedule. That is, for each passing minute or fraction of a mile, the amount due jumps to a new value. We'd have to say those are discontinuous.

The nature of electrical circuits is such that current is never discontinuous. Even when the circuit is disconnected by a switch, the arcing at the switch contacts ensures the current is continuous as it rapidly goes to zero.

Find the least common multiple of the pair of polynomials. 2y^2 - 50 & y - 5

ZanzabumX [31]

Answer:

The least common multiple is 2y^2 - 50.

Step-by-step explanation:

Least common multiple means the lowest thing you can multiply them both to. For example, the LCM of 2 and 4 is 2, because 2*2 = 4 and 4*1 = 4.

First, factor 2y^2 - 50.

2 (y^2 - 25)

2 (y - 5)(y + 5)

Looks like if we wanted to get 2y^2 - 50 starting with y - 5, we'd have to multiply it by 2(y + 5).

2y^2 - 50 * 1 = 2y^2 - 50

y - 5 * 2(y + 5) = 2y^2 - 50

So their least common multiple is 2y^2 - 50.
