Rewrite each equation in vertex form by completing the square. Then identify the vertex.
Cerrena [4.2K]
ANSWER

Vertex form:

y = ( {x + 4)}^{2} - 11

Vertex

V(-4,-11)

EXPLANATION

The given expression is

y = {x}^{2} + 8x + 5

We complete the square to get the vertex form.

Add and subtract half the square of the coefficient of x.

y = {x}^{2} + 8x + 16 + 5 - 16

y = ( {x + 4)}^{2} - 11

The vertex is

V(-4,-11)

Another submarine descent can be represented as y= -240 x where y is the elevation and x is time in hours. How long will it take
Juli2301 [7.4K]

Answer:e

Step-by-step explanation:

The equation for the submarine is given as y =-240x

Where y is the distance of the descent

x is the time in hours

and -240 is the rate of distance per unit time

To calculate how long it will take this submarine to reach the descent

x = y /-240

Find the composite function (please help)
anastassius [24]

Answer:

(f o h)(x) = -10x + 32

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Composite Functions

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x³ + 8

h(x) = ∛(12 - 5x)

(f o h)(x) is f(h(x))

<u>Step 2: Find Composite Function</u>

  1. Substitute:                         (f o h)(x) = 2(∛(12 - 5x))³ + 8
  2. Evaluate:                            (f o h)(x) = 2(12 - 5x) + 8
  3. Distribute 2:                       (f o h)(x) = 24 - 10x + 8
  4. Combine like terms:         (f o h)(x) = -10x + 32

And we have our final answer!
