Answer:

D. reflection across a vertical line

Step-by-step explanation:

Reflection is basically a mirror image. Since you can see that the first triangle is flipped over to get the second one, this is a reflection.

It is not a vertical translation; this means that the triangle shifted up or down.

It is not a horizontal translation, this means that the triangle shifted left or right.

It is not a rotation about point A either, this would have meant that the triangle spun around.

9. What is the vertex of the function? f(x) = 3x² - 8x + 10

Delvig [45]

Answer:

The vertex of the function is (1.333, 4.667)

Step-by-step explanation:

1. Calculate -b / 2a. This is the x-coordinate of the vertex.

2. simply plug -b / 2a into the equation for x and solve for y.

$Y = 3x^{2} - 8x + 10\\Compare with the form of y = ax^{2} + bx + c\\So that means a = 3, b = -8, and c = 10.$

Calculate -b/2a:

$X = -(-8)/2(3)$

$X = 8/6$

This is equal to 1.33 recurring

Plug 8/6 for x and solve for y:

$Y = 3x^{2} - 8x + 10$

$Y = 3(\frac{8}{6})^{2} - 8(\frac{8}{6}) + 10$

$Y = \frac{48}{9} - \frac{64}{6} + 10\\$

This is equal to 4.66 reccuring.

Kyle has $1 comma 000 in cash received for high school graduation gifts from various relatives. He wants to invest it in a cert

Vera_Pavlovna [14]

Answer:

$1077.283

Step-by-step explanation:

When complete the first year the amount will be:

1000 * 1.015= 1015

1.015 because the rate is added to the initial amount, that is: 100%+1.5% = 1 + 0.015= 1.015

When complete the second year the amount will be the last year amount adding the rate interest:

1015*1.015=1030.225.

To the third year:

1030.225*1.015=1045.678

To the fourth year:

1045.678*1.015=1061.363

To the fifth year:

1061.363*1.015=1077.283
