6. Which statement is true? 8.8D
quester [9]

Answer:

C.

Step-by-step explanation:

The two angles are better known as corresponding angles, and since the two lines are parallel, then the angles must be congruent. This means x = 115 degrees.

C. The values of x is 115 because the two angles shown are congruent.

<u>Why the other answers are wrong:</u>

A & B are wrong because it states the two angles are supplementary, but supplementary angles have to add up to 180 degrees and 115+115 is 230 not 180.

D is wrong because there's no logical explanation to why you would subtract 90 degrees from 115 to solve for x.

Un auto viaja con una velocidad promedio de 84 kilómetros por hora. ¿En cuánto tiempo viaja 462 kilómetros?
timama [110]

The car takes the time 5.5 hours i.e.5 hours and 30 minutes to travel 462 kilometres when the car travels at average speed of 84 kilometres per hour

Given the average speed of the car is 84 kilometres per hour and the distance to be travelled is 462 kilometres and asked to find the time taken for the journey of 462 kilometres

To calculate the time taken for the journey we use the below-mentioned formula

speed=\frac{distance}{Time taken}

(speed)×(Time taken)=distance

Time taken=\frac{distance}{speed}

Time taken=\frac{462 kilometres}{84KMPH}

Time taken=5.5 hours i.e.5 hours and 30 minutes

As a result, the time spent on the car journey is 5.5 hours

Hence, It takes the time 5hours and 5 minutes to travel 462 kilometres

How do you do this question?
vaieri [72.5K]

Answer:

(-∞, -2), (-2, -0.618), and (1.618, 3)

Step-by-step explanation:

The red plus (+) signs indicate the regions in which the function is concave up, and the red negative (-) signs indicate the regions in which the function is concave down.

Note that the sign of the concavity changes at an inflection point.

Let's examine the intervals given.

(-∞, -2): Yes, concave up.

(-∞, -1.17): No. Concave up in (-∞, -2) but concave down in (-2, -1.17).

(-2, 0): No. Concave down in (-2, -1.17) but increasing in (-1.17, 0.0).

(-1.17, 0.689): Yes. Concave up.

(-0.618, 1.618): No. Concave up in (-0.618, 0.689) but concave down in (0.689, 1.618).

(0, 3): No. Concave up in (0, 0.689), concave down in (0.689, 2.481), and concave up in (2.481, 3).

(2.481, ∞): Yes. Concave up.

The three intervals that are concave up are (-∞, -2), (-1.17, -0.689), and (2.481, ∞).
