The option that correctly describes the transformation that took place with triangle ABC is; <u><em>Option A.</em></u>

In transformations, translation simply means shifting an object from one position to the other while dilation simply means increasing or decreasing an object by a scale factor.

This means that translation preserves the lengths and angles of the object while the lengths and angles change with dilation.

Option A; Triangle MNO represents a translated triangle and as such the lengths and angles remain unchanged and so this option is correct.

Option B; Not true because both lengths and sides are preserved as stated above.

Option C; Transformation to PQR denotes dilation by a factor of 2 and as such the lengths and angles change. Thus this option is not true.

Option D; This is not true for the same reason in option C above.

Identify the vertex for the graph of y = −2x2 − 12x 1.

RUDIKE [14]

Answer: (-3,19)

Step-by-step explanation:

Here the given function is,

$y = -2x^2-12x+1$

$\implies y = -2(x^2+6x)+1$

$\implies y = -2(x^2+6x)+1+18-18$

$\implies y = -2(x^2+6x+9)+19$

$\implies y = -2(x+3)^2+19$

$\implies y = -2(x-(-3))^2+19$

Since, the standard equation of a quadratic function is $y = a(x - h)^2 + k$

Where (h,k) is the vertex of the function.

On comparing the equation of given function with this standard form,

We get, the vertex of the given function is (-3,19)

⇒ First option is correct.

Sue need 1 1/4 cups of flour for a batch of cookies.

MA_775_DIABLO [31]

4 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 4 4/4 = 5

6 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 6 6/4 = 7 1/2

7 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 7 7/4 = 8 3/4

8 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 8 8/4 = 10

The answer is C because 8 batches needs 10 cups of flour, and 7 batches is closest to 9 cups than 6 batches.

You can also look at it like this:

1 1/4c ≤ 9 (c is # of cups)

Or you could have multiplied 4, 6, 7, 8 to 1 1/4 or 1.25
