The equation of a circle in the x-y plane is shown above. What is the Radius of the Circle
2

Answers
Answer:
r = 2
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
Given
x² + y² + 4x - 2y = - 1 ← rearrange the x and y terms together
x² + 4x + y² - 2y = - 1
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(2)x + 4 + y² + 2(- 1)y + 1 = - 1 + 4 + 1
(x + 2)² + (y - 1)² = 4 ← in standard form
with r² = 4 ⇒ r = [tex]\sqrt{4}[/tex] = 2

Stock prices fell 250 points one day and 60 points the next day. What is the average change in stock prices over the two days
Answers
Answer:
the average change in stock prices over the two days is -155
Step-by-step explanation:
The computation of the average change in stock price over the two days is shown below:
= (-One day points - second day points) ÷ number of days
= (-250 points - 60 points ) ÷ 2 days
= -310 points ÷ 2 days
= -155
Hence, the average change in stock prices over the two days is -155
We simply applied the above formula so that the average change could come

The sum of two numbers is 58. If there difference is 28, find both numbers
Answers
Answer:
y = 15
x = 43
Step-by-step explanation:
this is giving us a system of equations because we know two things:
x + y = 58
x - y = 28
take the second equation and format it where you have simplified it for one variable:
x = 28 + y
(we did this by adding y to both sides)
now substitute this new value of x into the first equation:
28 + y + y = 58
simplify this to get 2y = 30
divide both sides by 2: y = 15
now substitute your new value of y into the second equation:
x = 28 + 15
x = 43

Sandy needs to create a triangular structure for her science project. She has two
pieces of bamboo measuring 6.5 inches and 8.1 inches. How long must her third piece
of bamboo be in order to create a triangle?
A 14.4 inches
B 14.6 inches
C 1.4 inches
D 1.6 inches
Answers
Answer:
The third piece must be 14.4 inches
Step-by-step explanation:
We use the triangle inequality theorem to get the third side
using the theorem, it must be that the sum of the two will be greater than the length of the third side
Hence we have it that;
a + b > c
6.5 + 8.1 > c
14.6 > c
So what this mean is that the third length is less than 14.6
the reasonable answer out of the options is thus 14.4 inches
reason for this is that the last two options will also not follow the inequality theorem

Answer:
The distance between points A and B is 13
Step-by-step explanation:
We need to find distance between points A and B
Looking at the graph,
Point A : (2,6) and Point B: (-3,-6)
We need to find the distance between these points.
The formula used is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\[/tex]
We have Points A : (2,6) and B: (-3,-6)
So, [tex]x_1=2, y_1=6, x_2=-3, y_2=-6[/tex]
Putting values in formula and finding distance
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\Distance=\sqrt{(-3-2)^2+(-6-6)^2} \\Distance=\sqrt{(-5)^2+(-12)^2} \\Distance=\sqrt{25+144} \\Distance =\sqrt{169}\\Distance = 13[/tex]
So, the distance between points A and B is 13

Domain: { 1,2,3,4,5,6}

Write first four terms of each sequence
2) f(n)=3n-1
Put n = 1, 3(1)-1 = 3-1 = 2
Put n = 2, 3(2)-1 = 6-1 = 5
Put n = 3, 3(3)-1 = 9-1 = 8
Put n = 4, 3(4)-1 = 12-1 = 11
So, First four terms are: 2,5,8,11
3) f(n)=n^2+2n+5
Put n = 1, (1)^2+2(1)+5= 1+2+5 = 8
Put n = 2, (2)^2+2(2)+5 = 4+4+5= 13
Put n = 3, (3)^2+2(3)+5 = 9+6+5 = 20
Put n = 4, (4)^2+2(4)+5 = 16+8+5 = 29
So, First four terms are: 8,13,20,29
4) f(n)=(n-1)(n-2)
Put n = 1, (1-1)(1-2) = 0(-1) = 0
Put n = 2, (2-1)(2-2) = 1(0) = 0
Put n = 3, (3-1)(3-2) = 2(1) = 2
Put n = 4, (4-1)(4-2) = 3(2) = 6
So, First four terms are: 0,0,2,6
5) f(n) = [tex]\sqrt{n-1}[/tex]
Put n=1 [tex]\sqrt{1-1}=\sqrt{0}=0[/tex]
Put n=2 [tex]\sqrt{2-1}=\sqrt{1}=1[/tex]
Put n=3 [tex]\sqrt{3-1}=\sqrt{2}= 1.41[/tex]

In right triangle, ABC m\angle A=37 find the measure of angle B.
Answers
Answer:
B = 53 degrees
Step-by-step explanation:
37+90=127
180-127=53
If the measure of the angle ∠A is 37°. Then the measure of the angle ∠B will be 53°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
In the right triangle ΔABC, the measure of the angle ∠A is 37°.
Angle A and angle B are complementary angles. Then the equation is given as,
∠A + ∠B = 90°
37° + ∠B = 90°
∠B = 90° - 37°
∠B = 53°
If the measure of the angle ∠A is 37°. Then the measure of the angle ∠B will be 53°.
