Answer:

(x-1)² = 3

Step-by-step explanation:

Given f(x)=x²−2x−2

Completing x²−2x−2 = 0 to square

x²−2x − 2=0
x²−2x + 1 - 3 =0
(x - 1)² - 3 = 0
(x - 1)² = 3

Correct choice is D

Mr. Win owns a toy store. He wants to display 12 new motion toys in the store window. Each toy uses 3 batteries. If N represents

Assoli18 [71]

Answer: See explanation

Step-by-step explanation:

You didn't state the sentences but let me help out based on the information given.

Number of new motion toys = 12

Number of batteries used by each toy = 3

Since N represents the total number of batteries he need, the value of N will be:

= Number of toys × Number of batteries used by each toy

= 12 × 3

= 36

That means N equals 36.

What is the volume of a sphere with a diameter of 8 m use 3.14 for pie round your answer to the nearest hundredth

deff fn [24]

Volume of the sphere is 300 m³

Step-by-step explanation:

Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m

⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)

Minchanka [31]

Answer:

$70\ \text{kilometers}$

Step-by-step explanation:

The scale of the map is 1 centimeter distance on the map represents 20 kilometers of actual distance.

The distance between the two cities is 3.5 centimeters on the map

$1\ \text{centimeters on the map}=20\ \text{kilometers of actual distance}$

So,

$3.5\times 20=70\ \text{kilometers}$

So, the distance between the two cities is $70\ \text{kilometers}$ .

You decide to install a fence around your property and want to know how many linear feet you have to determine the cost of the f

Debora [2.8K]

Answer:

The answer to this question is

The linear footage of the perimeter fence = 1250 feet

Step-by-step explanation:

To find the linear footage requires the footage measurement with a measuring tape. The linear footage indicates the length of the fence required to surround the property from which the cost of fencing the property can be estimated by multiplying the linear footage of the perimeter fence by the cost to build a unit length of fence

The linear footage of the perimeter fence to surround the property can be found by the equation for solving the perimeter of a rectangle which is

Perimeter = 2× (length+breadth) = 2×(475+150) = 2×625 = 1250 foot

The linear footage of the perimeter fence = 1250 foot
