Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth's crust. They are crystalline and often have a “squashed” (foliated or banded) texture.

Elevator 1 in an office building moved from ground position to a final position of +12 feet. Elevator 2 in the same building mov

Nezavi [6.7K]

Answer:

<h2>C. Elevator 1 is 12 feet above ground level and Elevator 2 is 15 feet below ground level.</h2>

Step-by-step explanation:

Let's break this down step-by-step

<h3>Step 1: Find Position of Elevator 1</h3>

This is just a simple addition problem

0 + 12 = 12

Elevator 1 is 12 feet above ground level

<h3>Step 2: Find Position of Elevator 2</h3>

This time, we use subtraction, since it is -15 feet

0 - 15 = -15

Elevator 2 is 15 feet below ground level

<h3>Step 3: Find the best statement</h3>

C. Elevator 1 is 12 feet above ground level and Elevator 2 is 15 feet below ground level.

I'm always happy to help :)

Use the quadratic function to predict y if x equals 6.<br><br> y = 2x2 − 2x − 2

Nadya [2.5K]

Answer:

The value of the polynomial $y = 2x^2 - 2x - 2$ is 58 for x = 6.

Step-by-step explanation:

Here, the given quadratic function polynomial is given as:

$y = 2x^2 - 2x - 2$

or, $y(x) = 2(x^2 - x - 1)$

Now, to find the value of y, when x = 6

⇒ $y(6) = 2((6)^2 - (6) - 1)$

= 2(36 - 6 -1) = 2(29)

= 58

⇒y(6) = 58

Hence, the value of the given polynomial $y = 2x^2 - 2x - 2$ is 58 for x = 6.
