What is the polar form of (x + 3)2 + y2 = 9?
r = −6 cos(θ)
r = −3 cos(θ)
r = 3 cos(θ)
r = 6 cos(θ)
Answers
Answer:
r = -6 cos(θ)
Step-by-step explanation:
got it right on edge
The equation (x + 3)² + y² = 9 into polar form is r = -6 cos(θ). The correct answer would be option (A).
What is the polar form?The polar form of a complex number is given by r(cos(θ) + i sin(θ)), where r is the distance from the origin and θ is the angle formed by the point and the positive x-axis.
To convert the equation (x + 3)² + y² = 9 into polar form, we can complete the square on the x and y terms:
(x + 3)² + y² = (x² + 6x + 9) + y² = 9
Then we can express x and y in terms of r and θ:
x = r cos(θ) , y = r sin(θ)
Substituting these values into the equation and simplifying:
r² cos²(θ) + 6r cos(θ) + r² sin²(θ) = 9
r²(cos²(θ) + sin²(θ)) + 6r cos(θ) = 0
r² + 6r cos(θ) = 0
r(r + 6cos(θ)) = 0
Since r ≠ 0
So, the polar form of the equation is:
r = -6cos(θ)
Thus, the correct answer would be an option (A).

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 4*x-3+x-(7*x-3)=0
Solve : -2x = 0
Multiply both sides of the equation by (-1) : 2x = 0

A. 18x – 80
B. 18x + 80
C. 18x + 28
D. – 62x
Answers
Answer:
A. 18x – 80
Step-by-step explanation:
18(x - 3) - 26
18x - 54 - 26
18x – 80
Because first you will expand the brackets, for this you will multiply everything that is outside the bracket to what’s inside (18 times x) which will give you 18x and (18 times -3) which will give you -54
Now your equation will be
18x -54 - 26
Next you will workout the liked terms with are -54 and -26, since they are both negative just add them together and keep the sign.
To get your final answer
18x -80

Find a 95% confidence interval for the percentage of registered voters in the city that are Independents. Round your answer to at least two decimal places.
Answers
Answer:
0.05<x<0.06
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = p' ±z * √p(1-p)/n
z is the z score at 95% CI
p is the proportion of the independent sample
n is the sample size
p' = X/n
p' = 0.25/200
p' = 0.00125
Given
z = 1.96
p = 25% = 0.25
n= 200
Substitute into the formula;
CI = p' ±1.96 *√0.25(1-0.25)/200
CI = p' ±1.96 * √0.25(0.75)/200
CI = p' ±1.96 * 0.0306
CI = p' ±0.0605
CI = 0.00125 ±0.0605
CI = (0.048, 0.06175)
CI = (0.05, 0.06)
0.05<x<0.06
In rectangle FGHI, diagonals FH and GI intersect at E. G F E H I • IE = 3x + 4 • EG = 5x - 6 What is the length of FH ?
Answers
Answer:
FH = 38
Step-by-step explanation:
Here, given the point of intersection of the two diagonals at E, we want to calculate the length of FH
The point of intersection of the diagonals is the midpoint of each as the diagonals bisect each other
thus,
3x + 4 = 5x - 6
5x-3x = 6+ 4
2x = 10
x= 10/2
x = 5
but Eg is 5x-6
and FH = 2EG
FH = 2(5x-6)
FH = 10x - 12
Substitute x = 5
FH = 10(5) -12
FH = 50-12
FH = 38
The length of FH is 38.
The calculation is as follows:
3x + 4 = 5x - 6
5x-3x = 6+ 4
2x = 10
x = 5
Here EG is 5x-6
and FH = 2EG
So,
FH = 2(5x-6)
= 10x - 12
Substitute x = 5
= 10(5) -12
= 50-12
= 38

How can you use addition rules to solve subtraction problems with integers?
Answers
Answer:
Not entirely sure about what the question is asking, but explanation of what I think it is asking.
Step-by-step explanation:
There are three basic rules of addition.
Positive + Positive = Positive Ex: 1+1=2
Negative + Negative = Negative Ex: -2+-2=-4
Negative + Positive = Positive or Negative depending on the value.
Ex= 1+(-2)=(-1)
Ex=2+(-1)=1
So subtraction problems can be turned into addition problems.
For example:
4-2 is the same as 4+(-2).
Or -5-7 is the same as -5+(-7).
Hope this makes sense.
what is the volume of a regular octahedron inside a cube with the length of its sides measuring 4 centimeters
Answers
Answer:
We conclude that the volume of a regular octahedron will be:
[tex]\:\:V\:\approx \:30.17[/tex] cmStep-by-step explanation:
Given
The length of one of the side or edge of a regular octahedron = a = 4 cm
To determine
The volume of a regular octahedron = V
Using the formula to determine the volume of a regular octahedron
[tex]V\:=\:\frac{\sqrt{2}}{3}a^3[/tex]
substituting a = 4 in the volume equation
[tex]V=\frac{\sqrt{2}\cdot \:4^3}{3}[/tex]
[tex]V=\frac{64\sqrt{2}}{3}[/tex] ∵ 4³ = 64
[tex]\:\:V\:\approx \:30.17[/tex] cm

economics?
a) 30% b) 90%
c) 70% d) None of these
Solution with som explanation
Answers
Answer:
a) 30%
Step-by-step explanation:
50% of the students were taking statistics subject, 30% economics and 10% both the subjects.
The probability a student takes only statistics = 50% - 10% = 40%
The probability a student takes only economics = 30% - 10% = 20%
The probability a student was taking neither statistics nor economics = 100% - (40% + 20% + 10%)
The probability a student was taking neither statistics nor economics = 30%

Henry rode his motorcycle from his house to a friend's house. After riding 10 miles, he realizes he has traveled 2/3 of the way. How far is Bob's house from his friend's house?
A. 20 miles
B. 15 miles
C. 12 miles
D. 25 miles
Answers
Step-by-step explanation:
2/3 of diatance = 10 miles
3/3 of distance = 10 * (3/2) = 15 miles.
The distance between the houses is 15 miles. (B)
Let the total distance covered= x
Distance covered= 10 miles
According to the question,
2/3 of x= 10
=> 2/3 × x= 10
=> 2x/3= 10
=> 2x= 10× 3
=> 2x= 30
=> x= 30/2
=> x= 15
Bob's house is 15 miles away from Henry's house.
Enrique predicts that he can make additional money from sales of accessories and services for computer products sold by his store. The table at the right shows predicted percent returns for such sales. For example, if the store makes x dollars selling computer products, Enrique predicts the store will make 0.05x dollars from selling accessories. Part A In January and February of this year, the store made $2,500 from sales of accessories and services. Let x represent the amount the store will make from sales of computer products from March through December. Write an equation that represents the predicted amount y that the store will make from sales of accessories and services for the entire year. If Enrique predicts sales from accessories and services for the entire year will be $5,000, about how much money must be made from computer product sales from March through December? Explain.
Answers
Answer:
Following are the solution to this question:
Step-by-step explanation:
x was its full computer product revenue from March to December. In january and february, the revenue towards products and services before x quantities for computer product revenues will happen between March to December is $2,500.
Whenever x quantity is sold, then 0.05x quantity was sold for supplies and equipment.
The sum of accessories to sell should be calculated, indeed, year-round.
It helps us to split into two parts
y = accessory sales in January and February + accessories sales in March and December
Use item 2
y = $2,500 + March to December accessories sale
Now use sections 1 and 3
y = $2,500 + 0.05x
The above equation rewriting gives
y = 0.05x + $2,500 (a)
This formula is compared with a standard y = mx+c interrupt slope
We got a pitch of 0.05 and a pitch of $2,500.
