Classify the limaçon represented by the equation r=(1/2)-(1/2)sin(theta)

1 answer:

4 0

We know that

Limacons are in the form
r=a(+-)b*sin (theta) or r=a(+-)b*cos (theta)

in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)

see the attached figure

the answer is the option
A. Cardioid

<RQT is a straight angle. What are m<RQS and m<TQS

never [62]

Answers:

x = 11
angle RQS = 106 degrees
angle SQT = 74 degrees

===========================================================

Explanation:

Straight angles are always 180 degrees in measure.

The two smaller angles shown add up to 180

(angle RQS) + (angle SQT) = angle RQT

(9x+7) + (6x+8) = 180

(9x+6x) + (7+8) = 180

15x+15 = 180

15x = 180-15

15x = 165

x = 165/15

x = 11

From here, we then know that,

angle RQS = 9x+7 = 9*11+7 = 99+7 = 106 degrees
angle SQT = 6x+8 = 6*11+8 = 66+8 = 74 degrees

Note how the two results add to 106+74 = 180 to help confirm the answers.

What type of function does this equation represent? 2 Y = 4 (1)

Sphinxa [80]

Answer:

2y=4 is a linear function

Step-by-step explanation:

Since 2y=4 is the same as 2y¹=4, then a degree of 1 makes the function linear, aka. a straight line.
