Answer:
B
Step-by-step explanation:
The image that the line will produce would be:
b). is parallel to the original line.
Given that,
Coordinates = [tex](1,1) and (5,7)[/tex]
Scale factor [tex]= 3[/tex]
As we know,
Slope [tex]= \frac{y_{2} - y_{1} }{{x_{2} - x_{1}} }[/tex]
where;
[tex]y_{2} = 7[/tex]
[tex]y_{1} = 1[/tex]
[tex]x_{2} = 5[/tex]
[tex]x_{1} = 1[/tex]
By putting these values,
Slope [tex]= (7 - 1)/(5-1)[/tex]
[tex]= 6/4[/tex]
[tex]=[/tex] [tex]1.5[/tex]
∵The image of the line would be ║ to the original line.
Thus, option b is the correct answer.

Complete the statements about the cone.

The radius is units.
The volume is Tot cubic units.
10
6
Answer:
The answers are:
The height is 6
The radius is 8
The volume is 128 π cubic units.
Step-by-step explanation:
The height is shown in the picture. So the first answer is 6.
To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius
The slant height 10, and the height is 6. So you plug those into the equation and solve.
[tex]\sqrt{10^{2}-6^{2} }[/tex] =
[tex]\sqrt{100-36}[/tex] =
[tex]\sqrt{64}[/tex] = 8
So the radius is 8.
Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.
[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units

The statements about the cone is that,
The height is 6 units, the radius is 8 units and the volume is 128π cubic units.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a cone.
We have to find the complete the statements related to the cone.
From the figure,
height of the cone = 6 units
Using the Pythagoras theorem,
Radius of the cone = √(10² - 6²) = 8 units
Volume of the cone = 1/3 π r² h
= 1/3 π × 8² × 6
= 128π cubic units
Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.

Which equation represents a line passing through the point (8, 9) with a slope of 3?
The equation of a line passing through the point (8, 9) with a slope of 3 is y = 3x - 15.
What is the equation of a line passing through two given points in 2-dimensional plane?Suppose the given points are [tex](x_1, y_1) and (x_2, y_2),[/tex]
then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
We have been given a line passing through the point (8, 9) with a slope of 3.
then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
Its slope would be:
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
m = 3
Therefore, the equation of the straight line
[tex](y - 9) = 3 (x -8)\\\\y - 9 = 3x - 24\\\\y = 3x -15[/tex]
Hence, the equation of a line passing through the point (8, 9) with a slope of 3 is y = 3x - 15.

Find the smallest number such that the remainder is 3 when it is divided by 16,20 or 24.
(step required,thank you)
Answer: 123
Step-by-step explanation:
Foe us to solve this, we have to find the lowest common multiple of 16, 20 and 24 first and then add 3 to the LCM. This goes thus:
Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160
Multiples of 20 = 20, 40, 60, 80, 10, 120, 140, 160
Multiples of 24 = 24, 48, 72, 96, 120
Therefore, the Lowe's common multiple is 120.
We then add the remainder of 3 and this will give:
= 120 + 3
= 123
Melanie is going to invest in an account paying an interest rate of 5.2% compounded
monthly. How much would Melanie need to invest, to the nearest hundred dollars,
for the value of the account to reach $19,600 in 19 years?
Answer:
7300
Step-by-step explanation:
I got it right
Melanie would need to invest an amount of $7300.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
The final amount in a compound interest can be calculated using the formula,
A = P (1 + [tex]\frac{r}{n}[/tex] )^(n t)
Here A is the final amount, P is the principal value, r is the rate of interest, n is the number of times interest is compounded per year and t is the number of years.
Given,
A = $19,600
r = 5.2% = 5.2/100 = 0.052
Since it is compounded monthly, n = 12
t = 19 years
Substituting,
19,600 = P (1 + [tex]\frac{0.052}{12}[/tex])^ (12 × 19)
19,600 = P (1.0043)^(228)
19,600 = P (2.68)
P = 19,600 / 2.68
P = 7313.0767 ≈ 7300 to the nearest hundred
Hence the value of the account will reach $19,600 n 19 years if she invest an amount of $7300.

In one company, 20% of the workers in the technical department applied for vacation at the same time. If 12 workers applied for vacation, how many tech workers are there, altogether?
Answer:
There are 60 tech workers altogether
Step-by-step explanation:
Let X be the total number of tech workers in the company
Out of X tech employees, 20 % applied for leaves
In totality, 12 tech employees are on leave
Thus,
[tex]\frac{20}{100} * X = 12[/tex]
On solving the above mathematical equation, we get -
[tex]X = \frac{12*100}{20} \\X = 60[/tex]
Hence, there are 60 tech workers altogether

Step-by-step explanation:
the input .. "x" in this case.. can be any number .. so the domain is all real numbers.
the output.. or range.. is limited.. b/c the square on the 'x" will always make that number positive.. and then it's multiplied by the negative 2.... so that term will always be negative. : | hmmmm so when is that squred term the smallest it can be? hmmm when it's zero... soooo this function will .. at it's greatest point be 3 and go down from there...

Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
20% = 20/100 = 20 ÷ 100 = 0.2.

Step-by-step explanation:
State whether 2.5 + π is rational or irrational. Explain.
Answer: 2.5 + π is an irrational number.
Step-by-step explanation:
Irrational numbers are numbers that can not be written as the quotient of two integer numbers, and they have an infinite number of digits after the decimal point (such that there is not periodicity in these digits).
So suppose that we have an irrational number and we add 1, then the infinite digits after the decimal point will still be there, so the sum will be also an irrational number.
The same can be seen for the sum between an irrational number and a rational number, where the infinite number of decimals after the decimal point will still be there (because the rational numbers have a finite or infinite but periodical decimals after the decimal point), so the sum between an irrational number and a rational number is always irrational.
In this case, we have the addition:
2.5 + π
Which is the sum of a rational number and an irrational number, so we can conclude that this is an irrational number.
