Answer:

Correct option is C ) r=3+2\,cos\theta

Step-by-step explanation:

Limacons are polar functions of the type:

r=a\pm\,b\,cos\theta

r=a\pm\,b\,sin\theta

Where |\frac{a}{b}|

In provided options part (a) and (d) constants 'a' and 'b' does not satisfied the condition,

in part (b) and (c) both satisfies the condition but in part (b) we get loop  inside the sketch.

so,  r=3+2\,cos\theta satisfies the condition of graph.

hence correct option is c )  r=3+2\,cos\theta .

Answer:

c. 3 + 2 cosθ

Step-by-step explanation:

a = 3, b = 2

Since a > b, 1 < \frac{3}{2} <2

we get a dimpled limacon.

50 POINTS PLEASE HELP ME HURRY
tankabanditka [31]

Answer:

Q1)

Rx = 3

in this reflection, the image has been reflected along the x = 3 line. then all the points on the image are reflected along this vertical line. the distance between each point and the vertical line is noted and by that same distance its moved to the opposite side of the vertical line, while the y coordinates stay the same.

A(2,-5)- x coordinate is 2, its 1 unit away from x=3, it should move by 1 unit to the other side of x = 3, then x = 4. y stays as it is.

A' - (4,-5)

B(-4,6) - distance from x = 3, is (-4-+3) is seven units, moves by 7 units to the other side

B' (10,6)

C(3,1) = distance from 3 = 0, therefore the point stays at is,

C' (3,1)

Q2)

next is a translation, in translation the size nor shape changes, each point in the original image moves the same distance in the same direction.

T (3,-6) (x,y) = this means that the x coordinates move by +3 points to the right and y coordinates move downwards by 6 units

A (2,-5) ---> (2+3,-5-6)

A' (5,-11)

B (-4,6) ---> (-4+3,6-6)

B' (-1,0)

C (3,1) ---> (3 + 3, 1-6)

C' (6,-5)

Q3)

r(90°,0)

this is a rotation done in the clockwise direction. then the image takes a rotation to the right direction around the origin. 

then the x, y coordinates of the preimage become ;

(x,y) = (y,-x)

A(2,-5) --> A' = (-5,-2)

B(-4,6) ---> B' = (6,4)

C(3,1)  ---> C' = (1,-3)

Which of the following answer choices is an equation for the circle with a center of (-2, 3) and a radius of 3?
mamaluj [8]

Answer:

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 2, 3) and r = 3 , then

(x + 2)² + (y - 3)² = 9 ← expand left side using FOIL

x² + 4x + 4 + y² - 6y + 9 = 9  ( subtract 9 from both sides )

x² + y² + 4x - 6y + 4 = 0 → A

a cylindrical can of soup has a height of 4 inches and a radius of 3 inches. what is the volume of the can? round your answer to
grandymaker [24]
The equation for volume is V= (pi)(R^2)xH 
For Pi use 3.14
So switch the variables for the numbers that we know 
V= (3.14)(3^2)x4
3^2= 9 
3.14 x 9= 28.26
28.26x9 = 113.04
113.04 to the nearest tenth would be 113.
