A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ____? units. The point (-7, __?) lies on this circle.
Answer:
the answer is 5 and (-7,5)
Step-by-step explanation:
The radius is 5, and the points (-7, 5) and (-7, -1) both lie on the circle.
Given that:
The points at which the circle is centered are (-3,2)
Passing points = (1,5)
The radius is calculated using the distance formula:
d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]
Substituting the coordinates, we have:
d =[tex]\sqrt{({1 - (-3))^2 + (5 - 2)^2[/tex]
= [tex]\sqrt{(1 + 3)^2 + (5 - 2)^2[/tex]
=[tex]\sqrt{(4^2 + 3^2)[/tex]
= [tex]\sqrt{(16 + 9)[/tex]
= 5
Therefore, the radius of the circle is 5 units.
The equation of a circle with center (h, k) and radius r is given by:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Substituting the values, we have:
[tex][-7 - (-3)]^2 + (y - 2)^2 = 5^2[/tex]
[tex](-7 + 3)^2 + (y - 2)^2 = 25[/tex]
[tex](-4)^2 + (y - 2)^2 = 25[/tex]
[tex]16 + (y - 2)^2 = 25[/tex]
[tex](y - 2)^2 = 9[/tex]
Taking the square root of both sides, we have:
y - 2 = ±3
Solving for y, we have two possible values:
y - 2 = 3
y = 5
y - 2 = -3
y = -1
The points (-7, 5) and (-7, -1) both lie on the circle.
Thus, the radius is 5, and the points (-7, 5) and (-7, -1) both lie on the circle.

Suzy drove to a hair appointment at 50mph. Her average speed on the return home was 40mph. The return home took 1/4hr longer because of heavy traffic. How far did she travel to her hair appointment?
Since Suzy return took 1/4 hr longer, how far Suzy travelled to her appointment is 50 mi
To answer the question, we need to know what distance travelled by Suzy is
Distance between Suzy's home and hair appointmentThe distance between Suzy and her appointment is d = vt where
v = Suzy's speed = 50 mph and t = time it takes to teach her appointment.So, d = 50t (1)
Now, since Suzy returns home at a speed of v' = 40 mph and takes her 1/4 hr longer to return home,her return time is , t' = (t + 1/4) h
Since the distance she ruturns home is the same, we also have that
d = v't'
= 40(t + 1/4) (2)
Equating (1) and (2), we have
50t = 40(t + 1/4)
50t = 40t + 10
50t - 40t = 10
10t = 10
t = 10/10
t = 1 hr
How far Suzy travelled to her appointmentSubstituting t = 1 into d = 50t, we have
d = 50(1)
d = 50 m
So, how far Suzy travelled to her appointment is 50 mi

(9,10)
Answer:
(3, 2)
(9, 10)
Step-by-step explanation:
Ordered pairs (3, 2) and (9, 10) is the solution of the equation 4x -1 = 3y + 5
4x -1 = 3y + 5 (given)Lets us check for (3, 2)L.H.S. = 4x - 1 = 4(3) - 1 = 12 - 1 = 11 (plug x = 3)R.H.S. = 3y + 5 = 3(2) + 5 = 6 + 5 = 11 (plug y = 2)-> L.H.S. = R.H.S.-> Ordered pair (3, 2) is a solution of the given equation.Similarly, ordered pair (9, 10) is also a solution of the given equation because L.H.S and R. H.S. are equal to 35 on plugging x = 9 and y = 10.Which of these ordered pairs is a solution to the linear inequality 3y – 2x ≥ 8?
(3, 1)
(1, 3)
(2, –4)
(–4, 2)
Answer:
(-4 , 2)
Step-by-step explanation:
Linear inequality:3y - 2x ≥ 8
The ordered point (-4 ,2) satisfies the inequality. So, (-4,2) is the solution for the equation.
3*2 - 2*(-4) ≥ 8
6 + 8 ≥ 8
14 ≥ 8
Find the Area and circumference of each circle below.
Answer:
2: area is ≈153.93804 and circumfrence is ≈43.9823
3: area is ≈706.85835 and circumfrene is ≈94.24778
Step-by-step explanation:
The formula for area is A = pi r^2
for 2 you would plug 7 in for r, then square it, then multiply it by pi.
for 3 you would divide the diameter, 30, by 2 to get r (15), then square it then multiply by pi.
The formula for cirumfrence is C = 2 pi r
for 2 you would multiply 7 by 2, then multiply that by pi
for 3 you dont need to do much since the diameter (30) is already 2r. Basically all you need to do for that one is multiply 30 by pi
