x3-x2-12x
Upload a written answer and response to the activity including an explanation of how you arrived at your answer/response (what steps did you take, etc.). This should include a few sentences of narration to explain the math behind your work. Please be sure you address all parts of the question.

Answers

Answer 1

Step-by-step explanation:

factor out x because that variable is common in all 3 terms

x (x2 - x - 12)

now you can factor

x (x-4) (x+3)

when you use FOIL you will see you arrive at the original answer.

so yes it is a factor

Help ASAP!! Geometry -

Find the volume of the solid. (FSSS!) Round answers to the nearest hundredth.

Answers

Answer:

x = 9.27 cm

Volume = 289.2 cm³

Step-by-step explanation:

SA = Surface Area

SA = 229.2 cm²

P = Perimeter of Base

P = 3(6)

P = 18 cm

H = Height of Solid

H = x

A = Area of Base(Equilateral Triangle)

A = 6²√3 / 4

A = 36√3 / 4

A = 9√3

A = 9(1.732)

A = 31.176

A = 31.2 cm²

SA = Surface Area

SA = PH + 2A

229.2 = 18x + 2(31.2)

229.2 = 18x + 62.4

229.2 - 62.4 = 18x

166.8 = 18x

9.266 = x

9.27 = x

x = 9.27 cm

V = Volume

V = AH

V = 31.2(9.27)

V = 289.224

V = 289.2 cm³

Graph units are in kilometers. What is the distance from Diego's ship to the closest island? Round the final answer to the nearest tenth of a kilometer. Do not round intermediate calculations. \text{ km} km

Answers

Answer:

5 kilometers

Step-by-step explanation:

Just use distance formula for each island to his boat

The distance between is the number of units between them, and the distance from Diego's ship to the closest island is 5.4 units

What is a point coordinate?

A point coordinate is the location of a point on the coordinate plane

From the question, the coordinate of point X is:

X = (-2, -4)

The closest island to point X is the island B, and the coordinate is:

B = (3, -6)

The distance is then calculated using:

XB =√[(x₁ - x₂)² + (y₁ - y₂)²]

So, we have:

XB =√[(-2 - 3)² + (-4 + 6)²]

Evaluate

XB = 5.4

Hence, the distance from Diego's ship to the closest island is 5.4 units

A spinner has an equal chance of landing on either red blue or green. You spin six times. What is the probability that spinner lands on red at least two times?

Answers

Answer:

0.8906 ( 4 decimal places)

Step-by-step explanation:

With an equal probability of landing in either blue or red, then

Probability of success, p = 0.5

Number of trials, n = 6

Probability of landing on red atleast twice Can be obtained using a cumulative binomial probability ;

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x ≥ 2) = p(x = 2) + p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6)

Obtaining the individual probabilities and summing them up or we could use a cumulative probability option on either a calculator, excel or an online binomial probability distribution.

Using an online binomial probability calculator :

P(x ≥ 2) = 0.890625

P(x ≥ 2) = 0.8906 ( 4 decimal places)

Step-by-step explanation:

Given that:

Number of sections = (A, B, C, D) = 4

Probability of spinner landing on section B on a single spin = required outcome / Total possible outcomes
