How can acceleration be changed without changing speed?

Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. If you're not changing your speed and you're not changing your direction, then you simply cannot be accelerating—no matter how fast you're going.

Triangle XYZ has vertices X(0, 2), Y(4, 4), and Z(3, –1). Graph △XYZ and its image after a rotation of 180° about (2, –3).
Alla [95]

The image of the triangle is to be formed by rotating ΔXYZ 180 degrees about the (2, -3) as shown in the graph.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Triangle XYZ has vertices X(0, 2), Y(4, 4), and Z(3, –1).

If the triangle is ΔXYZ. Then the image of the triangle is to be formed by rotating ΔXYZ 180 degrees about the (2, -3) as shown in the graph.

A truck travelled at a constant speed for 6 hours. Then , it decreased itd speed by 13 mph for the remaining 228 miles. If the t
kakasveta [241]

Answer:

 Time taken to travel remaining 228 miles = 2.4 hours.

Explanation:

Total distance = 876 miles.

Distance traveled after speed reduction = 228 miles

So, distance traveled before = 876 - 228 =648 miles.

Time taken for this = 6 hours.

Speed before speed reduction = 648/6 = 108 mph.

Speed after speed reduction = 108 - 13 = 95 mph

Time taken to travel remaining 228 miles = 228/95 = 2.4 hours.

Doug, who runs track for his high school, was challenged to a race by his younger brother, matt. Matt started running first, and
eduard

The speed of Matt is 10 mph.

Doug runs 2 miles an hour faster than Matt, so let Matt’s speed equal x miles per hour. Then Doug’s speed equals x + 2 miles per hour. Each lap is one-quarter of a mile, so Doug runs 1.5 miles in the time it takes Matt to run 1.25 miles.

Rate of Matt is x

Rate of Dough is (x + 2)

Time taken by Matt is 1.25/x

Time taken by Dough is 1.25/(x + 2)

Distance covered by Matt is 1.25

Distance covered by Dough is 1.5

Dough and  Matt  took the same amount of time from the time Doug started, so make an equation by setting the two times in the chart equal to each other, and then solve for x:

            \frac{1.5}{(x + 2)} = \frac{1.25}{x}

              1.5x = 1.25(x + 2)

              1.5x = 1.25x + 2.5

           0.25x = 2.5

                   x = 10

So Matt ran at 10 miles per hour.
