Does Anyone Get This? And If So Can You Help

Answers

Answer 1
The answer is :X^2 + 7x + 12
The mistake made was when expanding they added 3 and 4 together instead of multiplying it
Answer 2

Correct Answer:

[tex]x^2 + 7x + 12[/tex]

Step-by-step explanation:

The error that was made, is that they accidentally added 3 and 4 together, during the distribution, when they should have multiplied it, leaving them with 7 instead of 12.

Combine like terms. Your answer should contain decimals. 0.5(x4 − 9) + 15 = Please in 10 mins please

Answers

Answer:

x ≈ ±2.1407

Step-by-step explanation:

0.5(x⁴ - 9) + 15 = 0

Distribute the 0.5 across the parentheses.

0.5x⁴ - 4.5 + 15 = 0

Combine the constants.

0.5x⁴ + 10.5 = 0

Subtract 10.5 from both sides.

0.5x⁴ = -10.5

Divide both sides by 0.5.

x⁴ = 21

Take the fourth root of 21.

⁴√21 ≈ ±2.1407

x ≈ ±2.1407

What you would do is X/15 and 20/100 Now cross multiply so x100 = 15 x 20 15 x 20 = 300, but you need to have x by it self so 300/100 = 3

What is the area of this triangle?
A=bh2


a-54 cm²

b-90 cm²

c-108 m²

d-216 m²

Answers

Answer:

a

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 9 and h = 12 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

It’s a because 12x9=108 then divide it by 2 and you have 54

Okey.but where is your question
The answer for the first one is y=-1/2x+4, you can find this by graphing it and finding the slope by using rise over run and once you have the slope you can plot the rest of the points to find the y-int. For the other one it is y=-3x+8. I also really suggest using the Desmos graphing calculator online, you got plot the points and then once you have an answer you can check it by plugging in the equation.

A 36-foot long rope is tied from the top of a pole to a stake in the ground. If the stake is 17 feet from the base of the pole, find the height of the pole. Round to the nearest tenth if necessary.

Answers

Answer:

Perpendicular = 31.73 ft (Approx)

Step-by-step explanation:

Given:

Length of rope (Hypotenuse) = 36 ft

Base = 17 ft

Find:

Height of pole (Perpendicular)

Computation:

Perpendicular = √Hypotenuse² - Base²

Perpendicular = √36² - 17²

Perpendicular = √1,296 - 289

Perpendicular = 31.73 ft (Approx)

Answers

Answer:

The value of x is approximately 5

Step-by-step explanation:

Answer:

x=6.36

Step-by-step explanation:

In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:

[tex]9=x\sqrt{2}[/tex]

Multiply both sides by [tex]\sqrt{2}[/tex]

[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]

Divide both sides by 2

[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]

[tex]x=6.36[/tex] (this answer is approximate)

Therefore, x is equal to 6.36.

Which equation best represents the graph shown above?

Answers

Answer:

B

Step-by-step explanation:

Choose an x point. Then plug it in and see if you get the correct y.

For example, I chose an x point of -1. When x = -1, you can see that y = 4.

Plug it in to the equations, and you find that B is correct.

y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1

4 = 1 - (-2) + 1

4 = 1 + 2 + 1

4 = 4

URGENT!!! A factory process requires 3 steps to finish a product. The steps each have a mean completion time of A= 10 seconds and a standard deviation of o = 5 seconds. The time it takes to complete each step is independent from the other steps. Let T be the total completion time for the 3 steps.

Find the standard deviation of T.

Choose 1 answer:

OT = 15 seconds

Or = 75 seconds

or 15 seconds

or = v75 seconds

Answers

Answer:

d

Step-by-step explanation:

The standard deviation of T is equivalent to 5.

What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.Mathematically, we can write -

       [tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]

Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.

We can write that -

5 = √∑(x{i} - 10)²/√3

√∑(x{i} - 10)² = 5√3

(√∑(x{i} - 10)²)² = (5√3)²

∑(x{i} - 10)² = 25 x 3

∑(x{i} - 10)² = 75

Now, we can write that -

σ = √(75/3)

σ = √25

σ = 5

Therefore, the standard deviation of T is equivalent to 5.
