Answer:

C.

Step-by-step explanation:

When you study the images, it is clear that the black triangle has to be reflected over the y-axis to face the same direction as the red triangle. So, choice A is eliminated.

Once you reflect the black triangle across the y-axis, you have points at (-1, -1), (3, -4), and (3, -2). Meanwhile, the red triangle's coordinates are at (-3, 0), (1, -3), and (1, -1). From these points, you can tell that the x-values differ by 2 units and the y-values differ by 1 unit.

All of these conditions match the ones put forth in option C, so that is your answer.

Hope this helps!

Answer:

(C) Translation of 2 units right, 1 up, and a reflection over the y-axis.

Step-by-step explanation:

Ideally, we are looking for a reflection of the red image over the y-axis, and to do that, we can see how we need to move the black image.

In order for points Q and Q' to be a reflection of each other, they need to have the same y value, and be the exact same distance from the y axis, so the point that Q has to be at is (-1,-3).

Q is right now at (-3,-4) so we can translate this.

To get from -3 to -1 in the x-axis, we go right by 2 units.

To get from -4 to -3 in the y-axis, we go up one unit.

Now, if we reflect it, the triangles will be the same.

Hope this helped!

ArbitrLikvidat [17]

Answer:

the stock will sell for $59.16

Step-by-step explanation:

P0 =  2 * (1+0.2) / (1+0.105)  +  2 * (1+0.2) * (1+0.12)  /  (1+0.105)^2  +  

2*(1+0.2)*(1+0.12)^2 / (1+0.105)^3 +

[(2 * (1+0.2) * (1+0.12)^2 * (1+0.06) / (0.105-0.06))  /  (1+0.105)^3 ]

P0 = $59.16

Are my answers correct?
Snezhnost [94]

Step-by-step explanation:

In number 20 you put x is less than or equal to 25 ( x ≤ 25 )

It should be x is greater than or equal to 25 ( x ≥ 25 ) because it says it cannot be less than 25.

All your other answers are correct. Good job.
