(x-h)^2 + (y-k)^2 = radius^2
Plug in h and k immediately because that is something you automatically know. H and k are derived from the center of the circle. The center of the circle is (h,k). Don’t get tripped up though, your center of a circle has negative coordinates. When you have two negatives, they become positive.
So now you have:
(x+4)^2 + (y-2)^2 = radius^2
So figure out what the radius is. Use the distance formula to find out. You have a change of 5 from -4 to 1 in x. You have a change of 2 from 2 to 4 in y. Distance formula has the distance as the square root of x distance squared and y distance squared. That would mean that the distance/radius is equal to the square root of (25 + 4). 5 squared is 25 while 2 squared is 4.
The radius of the circle is equal to the square root of (29). However, looking back at the circle equation the radius should be squared for the equation. Square root of 29 squared gets you 29.
Plug that in and you get:
(x+4)^2 + (y-2)^2 = 29

The solution to the geometric progression are
a) The geometric progression converges , r = 0.1
b) The geometric progression converges , r = 0.2
c) The geometric progression diverges , r = 5
d) The geometric progression converges , r = 0.2
e) The geometric progression diverges , r = 5

What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
A geometric progression is said to converge if the common ratio r lies between -1 < r < 1
So , If -1 < r < 1, the geometric sequence converges
a)
The geometric progression is A = 0.3 + 0.03 + 0.003 + ...
The common ratio r = second term / first term
The common ratio r = 0.03 / 0.3
The common ratio r = 0.1
So , -1 < r < 1 and the GP converges
b)
The geometric progression is A = 0.25 + 0.05 + 0.01 + ...
The common ratio r = second term / first term
The common ratio r = 0.05 / 0.25
The common ratio r = 0.2
So , -1 < r < 1 and the GP converges
c)
The geometric progression is A = 0.23 + 1.15 + 5.75 + ...
The common ratio r = second term / first term
The common ratio r = 1.15 / 0.23
The common ratio r = 5
So , r > 1 and the GP diverges
d)
The geometric progression is A = 0.75 + 0.15 + 0.03 + ...
The common ratio r = second term / first term
The common ratio r = 0.15 / 0.75
The common ratio r = 0.2
So , -1 < r < 1 and the GP converges
e)
The geometric progression is A = 0.00025 + 0.00125 + 0.00625 + ...
The common ratio r = second term / first term
The common ratio r = 0.00125 / 0.00025
The common ratio r = 5
So , r > 1 and the GP diverges
f)
The geometric progression is A = 128,750 + 25,750 + 5,150 + ...
The common ratio r = second term / first term
The common ratio r = 25,750 / 128,750
The common ratio r = 0.2
So , -1 < r < 1 and the GP converges
Hence , the geometric progression is solved

Answers
The best approach to solve the problem is writing an equation. Given Avelina earns half of what Gus earns, the equation becomes Avelina's earnings = Gus's earnings / 2. On substituting Gus's earnings with $125, we get Avelina's earnings to be $62.50.
Explanation:The best problem-solving strategy that would be apt to solve this problem, 'Avelina earned half as much money as Gus. If Gus earned $125.00, how much money did Avelina earn?' is to write an equation. We know that Avelina earned half of what Gus earned. This can be represented by the equation: Avelina's earnings = Gus's earnings / 2.
Since we know that Gus earned $125, we can substitute this value into our equation: Avelina's earnings = $125 / 2. Solving this equation gives us the answer: Avelina earned $62.50.

Step-by-step explanation:
Two points on the graph are (-4, 0) and (0, 3). Moving from the first point to the second, we see x (the 'run') increase by 4 and y (the 'rise') increase by 3. Thus, the slope of this line is m = rise / run = 3/4.
Using the point slope form, we get:
y - 3 = (3/4)(x - 0), or
4y - 12 = 3x, or

4 0
Let x be the number of rides taken and y be the number of tickets remaining. We can write the equation for this linear function as:
y = -6x + 24
The y-intercept, 24, tells us how many tickets Jamie has before taking any rides (x = 0). He has 24 tickets. His first ride reduces that amount by 6, so the slope of this line is -6 (Jamie uses 6 tickets per ride).
The y-intercept is written as (0,24): Jamie has 24 tickets before any ride is taken. This is option C.

Step-by-step explanation:
The "y" coordinate of the midpoint will be equal to the average of the y coordinates of the endpoints, and the x coordinate of the midpoint will be equal to the average of the x coordinates of the endpoints, and so we get that...
The x coordinate of the midpoint = (5 + 3) / 2 = 8 / 2 = 4
The y coordinate of the midpoint = (21 + 15) / 2 = 36 / 2 = 18
So the right answer is A (4, 18)

What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number
1. Cost of a paperback = 25 cents = $0.25
Cost of a hardcover book = $1.25
There were 54 paperbacks and 163 hardcover books sold.
Money library raised = (0.25 × 54) + (1.25 × 163) = $217.25
2. Cost for round trip airfare = $398.60
Cost of room per night = $115.70
Cost of room for two nights = 2 × $115.70 = $231.40
Cab fare from airport to hotel = $40.00
Total fare from airport to hotel and the return = 2 × $40.00 = $80.00
Total cost = $398.60 + $231.40 + $80.00 = $710
3. Total working hour of Paula = 48 hours
Earning for first 35 hours = $14.50/h × 35
= $507.50
Remaining hours = 48 - 35 = 13 hours
Earning for next 13 hours = ($14.50/h × 1.5) × 13
= $282.75
Total earnings = $507.50 + $282.75 = $790.25
4. Number of cards Will has = 26
Number of cards Liam has = 19
When they combine, total cards = 26 + 19 = 45
When father also shared, total number of cards = 3 × 45 = 135
Number of cards Nestor has = 4 × 8 = 32
Total number of cards = 135 + 32 = 167

If m ∠ P = (12x + 7), m ∠ Q = (6x - 7), and ∠ P and ∠ Q are complementary angles, find m ∠ Q.
Answers
The value of m ∠ Q is 23°.
What are complementary angles?
Because the three angles of a triangle sum up to 180° and the right angle has already taken up 90°, the two non-right angles in a right-angled triangle are complementary. We say two angles "Complement" one other when their sums equal 90 degrees.
Here, we have
Given: m ∠ P = (12x + 7), m ∠ Q = (6x - 7), and ∠ P and ∠ Q are complementary angles.
The sum of the measures of two complementary angles is 90°.
So, m∠P + m∠Q = 90°
Substitute 12x+7 for m∠P and 6x−7 for m∠Q.
12x+7 + 6x−7 = 90°
18x = 90°
x = 5°
To find m∠Q, substitute 5 for x in 6x−7.
6×5 - 7 = 23°
m ∠ Q = 23°
Hence, the value of m ∠ Q is 23°.
