A sequence of transformations was applied to an equilateral triangle in a coordinate plane. The transformations used were rotati
Svetlanka [38]

Answer:

A- It must be an equilateral triangle with the same side lengths as the original triangle

Step-by-step explanation:

Well The Equilateral Triangle dont change at all But its position on the coordinate plane changes, So it must be still a Equilateral Triangle.

The other options are talking about how the equilateral triangle changes, But it not true only the positions on the coordinate plane changes.

Permutation question pictured! Thanks :)
lozanna [386]

Answer:

3,160,080

Step-by-step explanation:

  • The first place can be taken by any one of the 22 students.
  • The second place can be taken by any one of the remaining 21 students.
  • The third place can be taken by any one of the remaining 20 students.
  • The fourth place can be taken by any one of the remaining 19 students.
  • The fifth place can be taken by any one of the remaining 18 students.

<em>This basically means multiplying 22, 21, 20, 19, and 18. Or, the number of permutation of 22 things taken 5 at a time.</em>

The answer is 22*21*20*19*18 = 3,160,080

<em>Using formula  nPr=\frac{n!}{(n-r)!}=\frac{22!}{(22-5)!}=\frac{22!}{17!}=(22*21*20*19*18)=3,160,080</em>

A ball, thrown vertically upwards, from the ground, has its height h (in meters) expressed as a function of time t (in seconds),
Over [174]

Answer:

a. 15 meters.

b. 20 meters.

Step-by-step explanation:

a. The height of the ball at 3 seconds. 20 * 3 - 5 * (3)^2 = 60 - 5 * 9 = 60 - 45 = 15.

The ball will be 15 meters high.

b. The maximum height reached by the ball.

To get that, we need to find the vertex of the parabola. We do so by doing -b/2a to find the x-coordinate of the vertex.

In this case, a = -5 and b = 20.

-20 / 2(-5) = -20 / -10 = 20 / 10 = 2.

Then, we find the y-coordinate by putting 2 where it says "t".

h(2) =  20(2) - 5(2)^2 = (40) - 5(4) = 40 - 20 = 20 meters.

Hope this helps!
