Answer:
Rectangular coordinates.
x = 10cos^2(θ)
y = 5sin(2θ)
Step-by-step explanation:
Using the conversion equations from polar coordinates to rectangular coordinates:
x = r cos(θ)
y = r sin(θ)
We can rewrite the equation r = 10cos(θ) as:
x = 10cos(θ) cos(θ) = 10cos^2(θ)
y = 10cos(θ) sin(θ) = 5sin(2θ)
Therefore, the equation in rectangular coordinates is:
x = 10cos^2(θ)
y = 5sin(2θ)

Question below. Write an equation.
Answer:
16=3*2+5x
Step-by-step explanation:
3 is how many notebooks, 2 is cost per notebook, 5 is the cost of binders where x is the amount to bought, and 16 is how much you spent
Answer:
16 = 5x + 6
Step-by-step explanation:
You spend $16 on 3 notebooks and x binders. Notebooks cost $2 each and binders cost $5 each.
From this, we can see that our total amount of money spent is $16. This goes on one side of the equation.
T = 16
You have bought 3 notebooks that cost $2 each. An equation would be
n = 2x with x the number of notebooks bought. Plug 3 into x.
n = 2(3)
n = $6
You spent $6 on notebooks.
Your overall equation will be:
T = 5b + n
T is the total amount of money spent, x is the number of binders purchased, and n is the total amount of money spent on notebooks only.
Plug in the values you know.
16 = 5x + 6
To solve for x, subtract both sides by 6.
16 - 6 = 5x + 6 - 6
10 = 5x
Isolate x further by dividing both sides by 5.
x = 2
You bought 2 binders.

help me I keep getting it wrong
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{3}[/tex] x - 6 ← is in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes , then
y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (9, 2) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = [tex]\frac{2}{3}[/tex] x - 4 ← equation of parallel line
-------------------------------------------------------------------
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex] , then
y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (9, 2) into the partial equation
2 = - [tex]\frac{27}{2}[/tex] + c ⇒ c = 2 + [tex]\frac{27}{2}[/tex] = [tex]\frac{31}{2}[/tex]
y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{31}{2}[/tex] ← equation of perpendicular line

Step-by-step explanation:
The function/equation can be rewritten to fit the variables better. C=10t+2. C stands for the total cost, and t stands for the number of tickets. The total cost of tickets is the amount of tickets ($10 each) plus another $2 (probably some kind of fee).

Ayako claims that there are centers of dilations through which a dilation of line n by a factor leaves n changed. Determine whether each point below represents a center of dilation that supports ayako's claim
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. The points are not given, but I can explain it.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Dilation is the enlargement or reduction in the size of an object by a factor k. If a line AB is dilated by a factor k, with a center of dilation on the line AB, if the new line formed is A'B', then A'B' would lie on the same line AB irrespective of the dilating factor.
Dilation of a line segment is to smaller or larger a line with a specific scale factor. The line n when dilated with the center of dilation on the line, it will bring no change on the original line.
Given information
The line which is dilated is n.
DilationDilation of a line segment is to smaller or larger a line with a specific scale factor. If this scale factor is more than 1 then the line segment will larger otherwise smaller.
In the given problem a line n is dilated with the a scale factor that leaves the changed of n.
If the entire line is dilated and the point of this line passes through center of dilation then the change will be nothing. If dilated from the center of dilation the scale factor does not matter.
To find center of dilation which supports Ayako's claim the point below which represents the center of dilation are not given in the problem.
Hence, The line n when dilated with the center of dilation on the line, it will bring no change on the original line.

a $528 video game console is on sale for 15% off. if sales tax is 6.25% what is total coast
The term "off" indicates that the price of the item is reduced by the percentage off. Sales tax is however, added to the price of the item.
The total cost of the video game console is: [tex]\$476.85[/tex]
Given that:
[tex]Game = \$528[/tex]
15% off means that, the price is reduced by 15%.
So, we have:
[tex]Sales =Game - Game \times 15\%[/tex]
[tex]Sales = \$528 - \$528 \times 15\%[/tex]
[tex]Sales = \$528 -\$79.2[/tex]
[tex]Sales = \$448.8[/tex]
The total cost (when the sales tax of 6.25% is added) is:
[tex]Total = Sales + Sales \times 6.25\%[/tex]
[tex]Total = \$448.8 + \$448.8 \times 6.25\%[/tex]
[tex]Total = \$448.8 + \$28.05[/tex]
[tex]Total = \$476.85[/tex]
Hence, the total cost of the video game console is: [tex]\$476.85[/tex]

Answer:
m<NOQ = 139°
Step-by-step explanation:
Since lines KM and NP are parallel, alternate exterior angles KLJ and QOP are congruent.
m<QOP = m<KLJ = 41°
Angles NOQ and QOP are a linear pair and are supplementary, so the sum of their measures is 180°.
m<NOQ + m<QOP = 180°
m<NOQ + 41° = 180°
m<NOQ = 139°

Ellen and Bob went to Olive Garden for dinner. Ellen’s dinner costs $24.95 and Bob’s dinner costs $21.95. If they leave an 18% tip, what is the total cost of their dinner, including tip? (Round your answer to the nearest cent, and do not include the $ sign.)
Answer: 55.34
Step-by-step explanation:
24.95 + 21.95 = 46.90
46.90 x 18%
18% = .18
46.90 x 18 = 8.442
8.44 = cost of tip
8.44 + 46.90 = 55.34
