The table below represents the displacement of a horse from its barn as a function of time:

Mathematics
1 answer:
atroni [7]3 years ago
5 0

A. The y-intercept of the function is equal to the value of y when x = 0, so y = 8 ft

This means that the horse is already 8 ft away from the barn initially.

B. The average rate of change represents the slope of the equation. This can be calculated using the formula:

m = (158 – 58) / (3 – 1) = 50 ft / hour

C. Since we already have our y-intercept and slope, we can establish the line equation:

y = 50 x + 8

When y = 508 then x is,

508 = 50 x + 8

50 x = 500

x = 10 hours

It takes 10 hours to reach a displacement of 508 ft.

Who can help me?<br>please<br>Thank you​

The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,

110-2x+x+50+5x-40=180

Simplify this.

4x+120=180

4x=60

x=15

Now we can find each angle measure.

110-2x

110-2(15)

110-30

80

x+50

15+50

65

5x-40

5(15)-40

75-40

35

So the angle labeled 110-2x is the largest angle in the triangle.
