Convert r=7/(9sinθ−cosθ) to rectangular form.
Enter your answer in slope-intercept form by filling in the boxes. Enter values so that fractions are simplified.
Answer:
r = 7/(9sinθ - cosθ)
to rectangular form is:
y = (1/9)x + 7/9
Step-by-step explanation:
Given that
r = 7/(9sinθ - cosθ)
Consider the following polar-to-rectangular equivalents.
x² + y² = r²
x/r = cosθ
y/r = sinθ
So
r = 7/(9sinθ - cosθ)
Can be written as
r = 7/(9y/r - x/r)
r = 7/(1/r)(9y - x)
Multiplying through by (1/r)
1 = 7/(9y - x)
Multiplying through by (9y - x)
9y - x = 7
9y = x + 7
Divide both sides by 9
y = x/9 + 7/9
y = (1/9)x + 7/9
And this is the answer
Answer:
y = (1/9)x + 7/9
Step-by-step explanation:
Divide both sides by 9
y = x/9 + 7/9
y = (1/9)x + 7/9
Divide both sides by 9
y = x/9 + 7/9
y = (1/9)x + 7/9
what is the remainder of 14952 divided by 41 plzzzzz help ASAP will give brainiest answer
Answer: 364 with a remainder of 28
Step-by-step explanation:
14952/41
41 goes into 149 3 times
149 - (41 *3)
149 - 123 = 26
41 goes into 265 6 times
265 - (41*6)
265 - 246 = 19
41 goes into 192 4 times
192 - (41*4)
192 - 164 = 28
So 14952/41 = 364 with a remainder of 28

Total surface area of a cone [tex]S[/tex] = [tex]\pi r^{2}+\pi rl\\[/tex]
Since the diagram is half of a cone, its surface area will be [tex]S = \frac{\pi r^{2} +\pi rl}{2}[/tex]
r = radius of the cone
l = slant height
From the diagram diameter of the cone = 16m;
r = 16/2 = 8m
l = 17m
[tex]S = \frac{\pi (8)^{2} +\pi (8)(17)}{2}\\S = \frac{64\pi + 136\pi }{2} \\S = 32\pi + 68\pi \\S = 100\pi cm^{2}[/tex]

Olivia and Garrett each take out at $18,000 loan for a new car. Each how to repay the loan in 5 years. Olivia has interest rate 3.2% per year . Her monthly payment is $308 Because Garrett has a lower credit score he will pay an interest rate of 3.6% per year. His monthly payment will be $311. How much more will an $18,000 loan cost Garrett than Olivia.
Answer:
$180
Step-by-step explanation:
First, you have to calculate the amount that Olivia would have paid at the end of the loan which would be the result of multiplying her monthly payment for the number of payments:
Total payment= $308*(12*5)
Total payment= $308*60
Total payment= $18,480
Then, you have to calculate the amount that Garrett would have paid at the end of the loan:
Total payment= $311*(12*5)
Total payment= $311*60
Total payment= $18,660
Now, you have to calculate the difference in the amount Olivia and Garrett would have paid:
$18,660-$18,480= $180
According to this, an $18,000 loan will cost Garrett $180 more than Olivia.

A circle has a radius of $14.$ Let $\overline{AB}$ be a chord of the circle, such that $AB = 12$. What is the distance between the chord and the center of the circle?
Answer:
7.2
Step-by-step explanation:
The radius of the circle is 14.
The length of the chord is 12.
Half the length of the chord and radius form a right angled triangle as shown in the diagram below.
We need to find one of the sides of the triangle, d in the diagram.
Using Pythagoras rule:
[tex]14^2 = 12^2 + d^2\\\\196 = 144 + d^2\\\\d^2 = 196 - 144 = 52\\\\d = \sqrt{52} = 7.2[/tex]
The distance between the chord and the center of the circle is 7.2
Answer: 4sqrt10
Step-by-step explanation: The Chord is 12 so half the chord is 6 so the base is 6 and the radius is the hypotenuse, which is 14. and the distance is the missing leg.
so 14^2=6^2+x^2
196=36+x^2
sqrt160=x
4sqrt10=x

find the coordinates of H' after a reflection across the parallel lines; first across y = -2 and then across y = 2. Answer in form (a,b). Part 7a
Answer: H' = (-4, 4)
Step-by-step explanation:
H = (-4, -4)
reflect across y = -2:
H is 2 units below y = -2 so when reflected it will be 2 units above y = -2
--> the x-coordinate doesn't change the new y-coordinate is: 0
H' = (-4, 0)
reflect across y = 2:
H' is 2 units below y = 2 so when reflected it will be 2 units above y = 2
--> the x-coordinate doesn't change the new y-coordinate is: 4
H'' = (-4, 4)
b) The ratio of boys to girls in a school is 12:25. If there are 120 boys.
(i) how many girls are in the school?
(ii) what is the total number of boys and girls in the school?
Answer:
250 girls in the school and 370 students all total
Step-by-step explanation:
250 girls are in the school and 390 total students in the school.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
The ratio of boys to girls in a school is 12:25
Let, No. of boys in the school = 12x
No. of girls in the school = 25x
Total students in the school = 12x+25x = 39x
Given, there are 120 boys
So, 12x = 120
x = 10
No. of girls in the school = 25x = 25(10)
No. of girls in the school = 250
Total students in the school = 39x = 39(10)
Total students in the school = 390
Hence, 250 girls are in the school and 390 total students in the school.

O y = 4x - 16
O y = 4x + 16
Answer:
4x +16 the slope is 4 because its parallel to the other equation
The solution is: the equation of the line that is parallel to the line
y - 1 = 4(x + 3) and passes through the point (4, 32) is y = 4x + 16.
What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
Here, we have,
When two lines are parallel, their slope stays the same. thus we have y = 4x (so far)
Then use the point (4, 32) to plug in the coordinates to y = 4x + b
y = 4x + b (because y-intercept changes)
32 = 4(4) + b
32 = 16 + b
b = 32 - 16
b = 16
now, we get,
the y-intercept is 16 and the equation of the line that passes through the point (4,32) and is parallel to the line y = 4x + 13 is y = 4x + 16.
Hence, The solution is: the equation of the line that is parallel to the line
y - 1 = 4(x + 3) and passes through the point (4, 32) is y = 4x + 16.

Answer:
[tex](x^{-3} )^{2}[/tex]
[tex]x^6 x^{-12}[/tex]
Step-by-step explanation:
[tex](x^{3} x^{-6} )^{2}[/tex] is the expression given to be solved.
First of all let us have a look at 3 formulas:
[tex]1.\ p^a \times p^b = p^{(a+b)}\\2.\ (p^a \times q^b)^c = (p^{a})^c \times (q^{b})^c\\3.\ (p^a)^b = p^{a\times b}[/tex]
Both the formula can be applied to the expression([tex](x^{3} x^{-6} )^{2}[/tex]) during the first step while solving it.
Applying formula (1):
[tex](x^{3} x^{-6} )^{2}[/tex]
Comparing the terms of [tex](x^{3} x^{-6} )[/tex] with [tex]p^a \times p^b[/tex]
[tex]p=x, a =3, b=-6[/tex]
[tex]\Rightarrow x^{3+(-6)}\\\Rightarrow x^{3-6}\\\Rightarrow x^{-3}[/tex]
So, [tex](x^{3} x^{-6} )^{2}[/tex] is reduced to [tex](x^{-3} )^{2}[/tex]
Applying formula (2):
Comparing the terms of [tex](x^{3} x^{-6} )^{2}[/tex] with [tex](p^a \times q^b)^c[/tex]
[tex]p=q=x, a =3, b=-6, c=2[/tex]
[tex]\Rightarrow (x^{3})^2\times (x^{-6})^2\\\text{Applying Formula (3)}\\x^6 x^{-12}[/tex]
So, [tex](x^{3} x^{-6} )^{2}[/tex] is reduced to [tex]x^6 x^{-12}[/tex].
So, the answers can be:

area of a semicircle with a radius of 3
Answer: 9π/2
Step-by-step explanation:
A semicircle is half of a circle. Therefore, you must divide the area by 2.
[tex]A=\frac{\pi r^2 }{2}[/tex]
Since we know the radius, we can directly plug it into the formula.
[tex]A=\frac{\pi (3)^2}{2} =\frac{9\pi }{2}[/tex]
Since the problem stated to give the answer in terms of π, 9π/2 is our answer.
Answer:
[tex]\frac{9\pi }{2}[/tex] cm²
Step-by-step explanation:
The area of a semicircle can be expressed by the formula [tex]\frac{\pi r^{2} }{2} = A[/tex].
When you plug in the radius, you get [tex]\frac{\pi 3^{2} }{2} = \frac{\pi 9}{2} = \frac{9\pi }{2}[/tex].

Christopher scored 7 more than two times the questions Mathew scored on the math test. If Christopher scored 87 on the math test, what was Mathew's score?
Answer:
40
Step-by-step explanation:
To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:
C = 2M + 7
(Variables are representative of the first letter of each name)
Seeing as Christopher scored 87, we can put that into the equation and solve for M.
So, the equation will be:
87 = 2M + 7
Subtract 7 from both sides in order to isolate variable M on the right side.
80 = 2M
Now solve for M, which is 40 (divide both sides by 2).
