Please Help Me I'm So Bad At Math And Doing AFDA Really Doesn't Help..Order The Steps For This Equation

Answers

Answer 1

Answer:

See the arrangement below

Step-by-step explanation:

Given the expression

2x^2+x - 9 = 4x

Step 1: Write in standard form

2x^2 + x - 9 - 4x = 0

2x^2 + x - 4x - 9 = 0

2x^2 - 3x - 9 = 0

Step 2; identify the coefficients

The standard quadratic expression is ax^2+bx+c = 0

a = 2, b = -3, c = -9

Step 3: Using the general formula to find the roots

x = -b±√b²-4ac/2a

x = -(-3)±√(-3)²-4(2)(-9)/2(2)

Step 4: simplify

x =  -(-3)±√(-3)²-4(2)(-9)/2(2)

x = 3 ±√9+72/4

Step 5; Find the roots

x = 3 ±√81/4

x = 3 ±9/4

x = 3+9/4 and 3-9/4

x = 12/4 and -6/4

x = 3 and -3/2

Step-by-step explanation:

solution given.:

radius=[r] let

height[h]=8.7in

volume[V] of cylinder=171in³

π=3.14

we have

volume[V] of cylinder=πr²h

171=πr×8.7

Answers

Answer:

5

2y

40

Step-by-step explanation:

Answer:

y = 5

Because [2y] is on both sides of the equation, 8y must be equal to [40] so that the equation is true.

Step-by-step explanation:

Combine like terms to find the value of y.

8y + 2y = 2y + 40

10y = 2y + 40

8y = 40

y = 5

As we can see, we ended with 8y = 40, and 2y is the only term on both sides of the equation.

Assume a student shows up for EGR 280 completely unprepared and the instructor gives a pop quiz. Assume there are 6 questions, every single question is multiple choice question. Assume that each question has five options (a, b, c, d, and e), the student selects the answer randomly. Also assume that whether one question is answered correctly is independent of whether or not another question is answered correctly.

Required:
For a single question, what it the probability (p) that the student answers correctly?

Answers

Answer:

P=20%

Step-by-step explanation:

Let's suppose that each question in the test has one and only one correct answer. This means we have 1 desired outcome out of the total 5 desired outcomes. Therefore:

Probability=#of desired outcomes / #of possible outcomes

or

[tex]P=\frac{1 correct}{5 opctions}[/tex]

P=0.20

true?
(4 x 2) × (6-3) = 4 x_x2

Answers

Answer: 3

Step-by-step explanation: Start off by solving the right side of the equation: 4 x 2 is 8 and 6 - 3 is 3, and then you must do 8 x 3 which is 24. Now, the equation should look like this: 24 = 4 x _ x 2. Next, you should go a step further with the left side of the equation by multiplying 4 and 2. Now, the equation should look like this: 24 = 8 x _. For the final step, you must divide 8 on both sides to solve for the missing number. Since 24 divided by 8 is 3, your answer is 3.

h(x) = - x - 2

h(x) = 3

Set the output equal to the input,

a group of 4 students buy movies tickets for $24.At this rate, how much would 20 students pay for the movies

Answers

Answer:

$120.

Step-by-step explanation:

Just multiply 4 by 5 since it makes 20. Since we know that the price for 4 people is $24, you multiply 24 by 5 since you are paying for 20 people.

It’s 120 all you have to do is divide 24 by 4 to get how much it would be for one person then you multiply that by 20 and you get 120

C)

(5x)° + (2x + 7)° = 180°

D)

(5x)° = (2x + 7)°

Answers

Answer:

A. 5x° + (2x + 7)° = 90°

Step-by-step explanation:

Complementary angles add up to give us 90°.

From the given diagram, we have a part of the angles on a straight line as a right angle. Which means it is 90°. Therefore, the other two angles, 5x° and (2x + 7)° will add up to give us 90°. Thus, 5x° and (2x + 7)° are complementary angles.

Therefore:

5x° + (2x + 7)° = 90°

Answer:

r=14 in

Step-by-step explanation:

The volume of a cylinder is given by:

[tex]v = \pi \times {r}^{2} \times h[/tex]

So,

[tex]r = \sqrt{ \frac{v}{\pi \times h} } = \sqrt{ \frac{196 \times \pi}{\pi \times 1} } = \sqrt{196} = 14[/tex]

Step-by-step explanation:

solution given.:

radius[r] =r

height[h]=1in

volume[V] of cylinder=196πin³

we have

volume[V] of cylinder=πr²h

196π=πr×1

r²=[tex] \frac{196π}{π}[/tex]

r=[tex] \sqrt{196} [/tex]

r=14in

so radius is 14in

Scenario: The Cannon Instructions: View the video found on page 1 of this Journal activity. Using the information provided in the video, answer the questions below. Show your work for all calculations. The Cannon: Ernest's friend Nik is about to be shot out of a cannon. The path he will travel follows a parabolic arch that can be described by this polynomial. f(x) = –0.05(x2 – 26x – 120) He is supposed to land on a safety net 30 feet away. Does the function give you enough information to tell you where he will land? If so, how far from the cannon will he land?

Answers

Answer:

Part A

Yes

Part B

He will land at a point 30 meters from Cannon

Step-by-step explanation:

Part A

The given function that represent the path of the Cannon, which is the path of a parabolic arc, is presented as follows;

f(x) = -0.05·(x² - 26·x - 120)

We note that the height, 'h', of the path of a parabola at a horizontal distance, 'x' from the origin is equal to f(x)

Therefore, given that at the ground level, at the start and end of the flight, the f(x) = 0, we can write;

-0.05·(x² - 26·x - 120) = 0

∴ x² - 26·x - 120 = 0

x = (26 ± √((-26)² - 4 × 1 × (-120)))/(2 × 1)

Which gives;

x = 30 or x = -4

Therefore, he lands at a point 30 meters from the starting point

Therefore, the function gives enough information to tell where he will land

Part B

He lands at the point, x = 30 from the point the cannon was fired.
