write an equation that is perpendicular to x - 3y =3 and passes through the point (5,-9) in slope-intercept form.
9514 1404 393
Answer:
y = -3x +6
Step-by-step explanation:
The perpendicular line will have the coefficients of x and y swapped (and one of them negated), and will have a constant appropriate to the point the line needs to go through.
The equation will look like ...
x -3y = 3 . . . . . . . . . . . . . given line
3x +y = constant . . . . . . perpendicular line
where "constant" can be found by substituting for x and y.
3x +y = 3(5) +(-9)
3x +y = 6 . . . . equation in standard form
To put this in slope-intercept form subtract 3x:
y = -3x +6

A music group expects to sell a new compact disc (CD) at the rate R(t)=20,000e−0.12t CDs per week, where t denotes the number of weeks since the CD was first released. To the nearest thousand, how many CDs are expected to be sold during the first 12 weeks after the release?
Answer:
4739 CDs
Step-by-step explanation:
Given the function that models the rate at which the disc is sold expressed as;
R(t)=20,000e^−0.12t
t is the number of weeks since the CD was first released
We are to look for the number of CDs that are expected to be sold during the first 12 weeks after the release. To do this, you will simply substitute t = 12 into the modeled function and get R(12) as shown;
R(t)=20,000e^−0.12t
R(12)=20,000e^−0.12(12)
R(12)=20,000e^−1.44
R(12)=20,000(0.2369)
R(12) = 4738.56
Hence the total number of CDs expected to be sold to nearest thousand is 4739 CDs
Answer:
127,000

This table represents a linear function.
x y
0 5
5 15
This graph represents another function.
The greater unit rate of the two functions is ____. The greater y-intercept of the two functions is _____.
Given:
One linear function represented by the table.
Another linear function represented by the graph.
To find:
The greater unit rate and greater y-intercept.
Solution:
Formula for slope (unit rate):
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given table it is clear that the linear function passes through (0,5) and (5,15). The function intersect the y-axis at (0,15), so the y-intercept is 15.
[tex]m_1=\dfrac{15-5}{5-0}[/tex]
[tex]m_1=\dfrac{10}{5}[/tex]
[tex]m_1=2[/tex]
So, the unit rate of first function is 2.
From the given graph it is clear that the linear function passes through (0,6) and (-4,0). The function intersect the y-axis at (0,6), so the y-intercept is 6.
[tex]m_2=\dfrac{0-6}{-4-0}[/tex]
[tex]m_2=\dfrac{-6}{-4}[/tex]
[tex]m_2=\dfrac{3}{2}[/tex]
So, the unit rate of first function is [tex]\dfrac{3}{2}[/tex].
Now,
[tex]2>\dfrac{3}{2}[/tex]
[tex]m_1>m_2[/tex]
And,
[tex]15>6[/tex]
Therefore, the greater unit rate of the two functions is 2. The greater y-intercept of the two functions is 15.
Answer:
The greater unit rate of the two functions is 2.
The greater y-intercept of the two functions is 6.

Find the measure of each side indicated. Round to the nearest tenth.
Answer:
Step-by-step explanation:
to find x we can use tangent function
tan 31= x/9
0.60=x/9
x=0.60*9=5.4 choice B
The measure of x side.
We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.
We have to determine the value of x.
Therefore we use here the trigonometric ratio
What is the tan ratio?[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]
Therefore we get
tan 31= x/9
tan(31)=0.60
0.60=x/9
Isolate the x
x=0.60*9
x=5.4
Therefore option B is correct.

A circle has a diameter of 6 meters. Which statement about the circumference and area is true?
A comparison of the area and circumference is not possible since the area cannot be determined.
The numerical value of the circumference and area are equal.
The numerical value of the circumference is greater than the numerical value of the area.
The numerical value of the circumference is less than the numerical value of the area.
Answer:
The numerical value of the circumference is greater than the numerical value of the area.
Step-by-step explanation:
This has already been answered
The numerical value of the circumference is less than the numerical value of the area.
Which statement is true?For a circle of radius R, remember that the diameter is twice the radius, we have:
area = pi*R^2
And the circumference is:
C = 2*pi*R
In this case, we have:
D = 6m
R = 6m/2 = 3m
The circumference is:
C = 2*3.14*3m = 18.84m
And the area:
A = 3.14*(3m)² = 28.26 m^2
So the area is larger than the perimeter, the true statement is:
"The numerical value of the circumference is less than the numerical value of the area."
