Which of the following is the equation of a line that passes through the point (3,2) and is parallel to the y-axis? a. x = 2 b. y = 3 c. x = 3 d. y = 2

Option C is right answer

Step-by-step explanation:

We have in coordinate geometry a straight line in slope intercept form as

y = mx+c

where m is the slope and c is the y intercept

There are special lines when m=0 and m = infinity.

When a line is parallel to y axis, it has slope = tan90 = infinity.

Hence line will have equation of the form x = a for some a.

Since the line passes through (3,2) we can find a using this.

Substitute x value to get 3 = x

Hence equation of the line is x =3

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
