How Do I Start This Problem? I Don't Need Help With The Graphing Part.

Answers

Answer 1

Answer:

x = 6 , y = 0   (x , y) = (6 , 0)

x = 12, y = 3   (x , y) = (12 , 3)

x = 24, y = 9   (x , y) = (24 , 9)

Step-by-step explanation:

Simply plug in a x, and find a y that would make the equation true:

When x = 6:

6 - 2y = 6

6 (-6) - 2y = 6 (-6)

-2y = 0

(-2y)/-2 = (0)/-2

y = 0

When x = 6, y = 0    (x , y) = (6 , 0)

When x = 12:

12 - 2y = 6

12 (-12) -2y = 6 (-12)

-2y = -6

(-2y)/-2 = (-6)/-2

y = 3

When x = 12, y = 3   (x , y) = (12 , 3)

When x = 24:

24 - 2y = 6

24 (-24) - 2y = 6 (-24)

-2y = -18

(-2y)/-2 = (-18)/-2

y = 9

When x = 24, y = 9   (x , y) = (24 , 9)

Find the volumes of the solids generated by revolving the regions bounded by the graphs of the equations about the given lines.
y = root x
y = 0
x = 3
the x-axis
the y-axis
the line x = 3
the line x = 6

Answers

Answer:

x-axis = [tex]\frac{9\pi }{2}[/tex]

y-axis = [tex]\frac{4\pi }{5} .3(^{\frac{5}{2} } )[/tex]

Line x =3 :  [tex]\frac{44\sqrt{3} }{5} \pi[/tex]

Line x = 6 : [tex]\frac{84\sqrt{3}\pi }{5}[/tex]

Step-by-step explanation:

Given lines : y = √x

                     y = 0

                     x = 3

To determine the volumes generated we will use the disk method for each of the lines,

attached below is the detailed solution for  line x =3 , same procedure will be repeated for each value of x and y to obtain the given results

The volume generated  ( x axis )

= [tex]\frac{9\pi }{2}[/tex]

volume generated ( y _axis )

=  [tex]\frac{4\pi }{5} .3(^{\frac{5}{2} } )[/tex]

Volume about  x = 3

=  [tex]\frac{44\sqrt{3}\pi }{5}[/tex]

Volume about  x = 6

= [tex]\frac{84\sqrt{3}\pi }{5}[/tex]

An algebraic expression that represents the product of r cubed and one hundred seven is 107r³.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that represents the product of r cubed and one hundred seven.

Therefore, an algebraic expression that represents the situation

r cubed = r³

one hundred seven = 107

Thus, it would be;

107r³

Hence, an algebraic expression that represents  the product of r cubed and one hundred seven is 107r³.

All the fourth-graders in a certain elementary school took a standardized test. A total of 82% of the students were found to be proficient in reading, 74% were found to be proficient in mathematics, and 65% were found to be proficient in both reading and mathematics.A student is chosen at random. What is the probability that the student is proficient in neither reading nor mathematics

Answers

Answer:

0.09 = 9% probability that the student is proficient in neither reading nor mathematics

Step-by-step explanation:

We solve this question treating the events as Venn probabilities.

I am going to say that:

Event A: A student is proficient in reading.

Event B: A student is proficient in mathematics.

A total of 82% of the students were found to be proficient in reading

This means that [tex]P(A) = 0.82[/tex]

74% were found to be proficient in mathematics

This means that [tex]P(B) = 0.74[/tex]

65% were found to be proficient in both reading and mathematics.

This means that [tex]P(A \cap B) = 0.65[/tex]

What is the probability that the student is proficient in neither reading nor mathematics?

This is:

[tex]P = 1 - P(A \cup B)[/tex]

In which

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

With the values that we have:

[tex]P(A \cup B) = 0.82 + 0.74 - 0.65 = 0.91[/tex]

Then

[tex]P = 1 - P(A \cup B) = 1 - 0.91 = 0.09[/tex]

0.09 = 9% probability that the student is proficient in neither reading nor mathematics

Probability/ return: 0.20/ -4%; 0.50/ 4%; 0.10/ 7%; 0.20/ 8%.
The investment's expected return is _% (round the two decimal places)
The investment's standard deviation is % (round the two decimal places)
Should Gautney invest in this security? (select the best choice below)
a) yes. B.J. Gautney Enterprices should invest in this investment because the return is lower than treasury bill and the level of risk higher than the treasury bill.
B) no. B.J. Gautney Enterprises should not invest in this investment because the return is lower than the treasury bill and the level of risk higher than the treasury bill.
