The point (-3,2) lies on a circle whose equation is (x + 3)^2 + (y + 1 )^2 =r^2. Which of the following must be the radius of the circle?
Answers
Answer:
1. 3
2. A
Step-by-step explanation:
1. (-3+3)^2 + (2 + 1)^2 - r^2 = 0
0 + 9 - r^2 = 0
r^2 = 9
r = 3
2. 2x^2 + 4x + 2y^2 + 12y = - 6
Divide by 2.
(x^2 + 2x) + (y + 6y) = -3
Remember how to complete the square..
(b/2)^2
So...
(2/2) ^ 2 = 1
(6/2) ^ 2 = 9
(x^2 + 2x + 1) + (y^2 + 6y + 9) = -3 + 1 + 9 <--- You must remember to add whatever you add on the left to the right!
Now.. rewrite in standard form..
(x+1)^2 + (y+3)^2 = 7
Careful!! the circle equation is written as
(x - h)^2 + (y - h)^2 = r^2
Meaning that the radius is square root of 7. At center (-1, -3)

When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1
i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅
To find the slope of a line, we divide the vertical distance by the horizontal distance.
We'll use the trial and error method to find the right pairing
Let's start with A(3, 3) and B(12, 6)
Vertical distance =
Horizontal distance =
The slope AB = ³/₉ = ¹/₃
We want BC to have a slope -1 ÷ ¹/₃ = -3
Try C(16, -6); check the slope with B(12, 6)
Vertical distance =
Horizontal distance =
Slope of BC = -12 ÷ 4 = -3
The slope BC = -3 is the value we want so, tile 1 pair with tile 4
-------------------------------------------------------------------------------------------------------------
Let's do A(-10, 5) and B(12, 16)
Vertical distance = 16 - 5 = 11
Horizontal distance = 12 - -10 = 22
Slope AB = ¹¹/₂₂ = ¹/₂
The perpendicular slope would be -1 ÷ ¹/₂ = -2
Try C(18, 4) with B(12, 16)
Vertical distance = 16 - 4 = 12
Horizontal distance = 12 - 18 = -6
Slope BC = ¹²/₋₆ = -2
Slope BC and slope AB perpendicular, so tile 3 matches with tile 6
--------------------------------------------------------------------------------------------------------------
Let's try A(12, -14) and B(-16, 21)
Vertical distance = 21 - -14 = 35
Horizontal distance = -16 - 12 = -28
The slope AB = ³⁵/-₂₈ = ⁵/₋₄
We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅
Try C(-11, 25)
Vertical distance with B = 25 - 21 = 4
Horizontal distance with B = -11 - -16 = 5
The slope = ⁴/₅
Tile 7 matches tile 8
--------------------------------------------------------------------------------------------------------------
Take A(-12, -19) and B(20, 45)
Vertical distance = 45 - -19 = 64
Horizontal distance = 20 - -12 = 32
Slope AB = ⁶⁴/₃₂ = 2
We need the perpendicular slope to be -1 ÷ 2 = -¹/₂
We have C(6, 52) and checking the slope with B(20, 45)
Vertical distance = 45 - 52 = -7
Horizontal distance = 20 - 6 = 14
The slope is ⁻⁷/₁₄ = -¹/₂
Tile 9 pairs with tile 2
-----------------------------------------------------------------------------------------------------------
Conclusion
Tile 1 ⇒ Tile 4
Tile 3 ⇒ Tile 6
Tile 7 ⇒ Tile 8
Tile 9 ⇒ Tile 2
Tile 5 and Tile 10 do not have pairs

A tree was 63 inches tall. Several years later it was 107 inches tall.
What was the percent increase, to the nearest hundredth, of the height of the tree? Enter the answer in the box.
percent
Answers
Answer:
69.84%
Step-by-step explanation:
percentage increase
[tex]\frac{107-63}{63} \times 100\\=\frac{44}{63} \times 100\\=\frac{4400}{63} \\=69.84/%[/tex]
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The percentage increase in the height of the tree is 69.84%.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Height of the tree = 63 inches.
Height after several years = 107 inches.
Now,
The percentage increase in the height of the tree.
= (107 - 63)/63 x 100
= 44/63 x 100
= 69.84%
Thus,
The percentage increase in the height of the tree is 69.84%.

fifteen darts have landed on the dart board shown. each dart scores 3,5, or 7 points. in how many different ways can the fifteen darts score a total of 75 points
Answers
Answer:
The answer is "8".
Step-by-step explanation:
Let the number are a, b, c then value is as follows:
a= 3
b= 5
c= 7
The addition of equation ⇒ a+b+c =15....................(i)
multiply by the value ⇒ 3a + 5b + 7c = 75 ...............(ii)
let b= 15-a-c which subtract from equation (ii)
equation:
⇒ 3a + 5b + 7c = 75
⇒ 3a + 5(15-a-c) + 7c = 75
⇒ 3a +75-5a-5c+7c = 75
⇒ 3a -5a-5c+7c = 75-75
⇒ -2a + 2c = 0
⇒ 2(c-a) = 0
⇒ (c-a) = 0
⇒ c=a
if we put value in between 0 to 7 from it satisfies the two equations, with c=a and b = 15 - a - c. So, the correct answer is 8.

Answer:
The congruence statement tells you that both angle B and angle E are equal, since the triangles are identical!
Step-by-step explanation:
We want to set the equations equal to each other.
2x+31=7x-24
We need to isolate our variable, which is X.
1. Add 24 to both sides.
New Equation: 2x+55=7x
2. Subtract 2x from both sides.
New Equation: 55=5x

3 [tex]\frac{1}{2\\}[/tex] = [tex]\frac{7}{2}[/tex] and 4 [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{5}[/tex]
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take [tex]\frac{22}{5}[/tex] and mutiply both numbers by 2 and get [tex]\frac{44}{10}[/tex].

Answers
Answer:
Density: 1.6g/cm^3
Step-by-step explanation:
Density = mass/volume
Mass: 12.9g
Volume: 8cm^3
12.9/8 = 1.6125
Rounded to tenths place.
1.6 grams/cm^3
Answer:
1.61 g/cm³
Step-by-step explanation:
Density is measured as the mass divided by the volume:
d = m / v, where d is the density, m is the mass, and v is the volume
Here, our mass is 12.9 g and our volume is 8 cm cubed, so plug these in:
d = m / c
d = 12.9 g / 8 cm³
d = 1.6125 ≈ 1.61 g/cm³
The density is 1.61 g/cm³.
