Answer:

-1,325 ft below

Step-by-step explanation:

0 is surface - 1,500 = -1,500

1,500 + 525 = -975

-975 - 350 = -1325

Angle XYZ is rotated 270 degrees counterclockwise about the origin to form angle X’Y’Z’. Which statement shows the measure of an

8090 [49]

It is fine that you did not include the measure of angle XYZ in your posting.

This question is testing your knowledge of the four types of transformations.
1) Translations - an item is "slid" to a new location.
2) Reflections - an item is "flipped" (usually over the x-axis or y-axis)
3) Rotations - an item is rotated, usually around the origin (the point (0,0) is the center of most rotations, especially in high school math).
4) Dilations - an item is enlarged or reduced by a certain ratio.

It the first three, the image after the transformation is congruent to the pre-image. It has the same size and shape. It is simply flipped, rotated, slid...

But... in the fourth, dilation, the image now has a different size. It is still, however the same shape.

In geometry terms, after the first three transformations, the image is still "congruent" to the pre-image. After dilation, the image is "similar" but not "congruent."

So... all that to say that when you rotate an angle around the origin, the measure of the angle doesn't change.

So the first choice is correct. The measure of the image of the angle is the same as the measure of the angle.

In a seafood stew, Erin wants to use lobster, crab, and shrimp. She wants one part lobster, two parts crab, and three parts shri

alukav5142 [94]

Answer:

Answer: (B) 3

Step-by-step explanation:

20x + 15(2x) + 10(3x) = 40

20x + 30x + 30x = 40

80x = 40

x = 40/80

x = 1/2

Find the amount of lobster

Lobster = x = 1/2 pound

Find the amount of crab:

Crab = 2x = 2(1/2) = 1 pound

Find the amount of Shrimp:

Shrimp = 3x = 3(1/2) = 3/2 pounds

Find the total pounds of seafood:

Total = 1/2 + 1 + 3/2 = 3 pounds

What is the equation written in vertex from of a parabola with a vertex of (4, –2) that passes through (2, –14)?

vichka [17]

Answer:

y = -3(x - 4)² - 2

Step-by-step explanation:

Given the vertex, (4, -2), and the point (2, -14):

We can use the vertex form of the quadratic equation:

y = a(x - h)² + k

Where:

(h, k) = vertex

a = determines whether the graph opens up or down, and it also makes the parent function <u>wider</u> or <u>narrower</u>.

<u>positive</u> value of a = opens <u><em>upward</em></u>
<u>negative</u> value of a = opens <u><em>downward</em></u>
a is between 0 and 1, (0 < a < 1) the graph is <u><em>wider</em></u> than the parent function.
a > 1, the graph is <u><em>narrower</em></u> than the parent function.

<em>h </em>=<em> </em>determines how far left or right the parent function is translated.

h = positive, the function is translated <em>h</em> units to the right.
h = negative, the function is translated |<em>h</em>| units to the left.

<em>k</em> determines how far up or down the parent function is translated.

k = positive: translate <em>k</em> units <u><em>up</em></u>.
k = negative, translate <em>k</em> units <u><em>down</em></u>.

Now that I've set up the definitions for each variable of the vertex form, we can determine the quadratic equation using the given vertex and the point:

vertex (h, k): (4, -2)

point (x, y): (2, -14)

Substitute these values into the vertex form to solve for a:

y = a(x - h)² + k

-14 = a(2 - 4)² -2

-14 = a (-2)² -2

-14 = a4 + -2

Add to to both sides:

-14 + 2 = a4 + -2 + 2

-12 = 4a

Divide both sides by 4 to solve for a:

-12/4 = 4a/4

-3 = a

Therefore, the quadratic equation inI vertex form is:

y = -3(x - 4)² - 2

The parabola is downward-facing, and is vertically compressed by a factor of -3. The graph is also horizontally translated 4 units to the right, and vertically translated 2 units down.

Attached is a screenshot of the graph where it shows the vertex and the given point, using the vertex form that I came up with.
