If 10 +30 +90+...=2657200, what is the value of n?
The number of terms n of the geometric progression is n = 12
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
10 + 30 + 90 + .... = 2657200
And , let the number of terms be n
common ratio r = 30 / 10 = 3
where sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
On simplifying , we get
2657200 = 10 ( 3ⁿ - 1 ) / ( 2 )
Divide by 5 on both sides , we get
3ⁿ - 1 = 5,31,440
Adding 1 on both sides , we get
3ⁿ = 5,31,441
Taking log on both sides , we get

What is the slope of the line through (-2,-2)(-2,-2)left parenthesis, minus, -2, comma, -2, right parenthesis and (2,-4)(2,−4)left parenthesis, 2, comma, minus, 4, right parenthesis?
Step-by-step explanation:
To find the slope of the line between two points, you can use the formula:
slope (m) = (y2 - y1) / (x2 - x1)
Plugging in the given coordinates, we have:
m = (-4 - (-2)) / (2 - (-2))
m = (-4 + 2) / (2 + 2)
m = (-2) / (4)
m = -1/2
The slope of the line through the points (-2, -2) and (2, -4) is -1/2.

Suppose we drop a ball from a height of 10 feet. After each bounce, it returns to a height that is k% of the height from which it last fell. After the 5th bounce, it returns to a height of 9.04 feet. We will ignore things like friction and air resistance so that the terms form a geometric sequence.

223
9. The ball returns to 98.00% of its previous height after each bounce Option B
10. It will take 183 bounce until the ball bounces back to a height less than 3 inches. Option B
How do we solve for k% of previous height?To solve for k% of previous height after each bounce, we say
10×(k/100)⁵ = 9.04
k = [tex](9.04/10)^{1/5}[/tex]×100
k = 98.00
To find out how many bounces it takes for the ball to bounce back to a height less than 3 inches (or 0.25 feet), we use the inequality
10 × (0.961)ⁿ < 0.25
The logarithm of both sides gives
n × log(0.961) < log(0.025)
n > log(0.025) / log(0.961)
n > 182.593

The solution of the function is as follows:
f(3) = 16
h(0) = -4
h(g(x)) = 3x + 5
g(y) = y + 3
f(x) - h(x) = x² - x + 5
How to solve function?A function relates input and output. In other words, a function is an expression that defines a relationship between one variable (the independent variable) and another variable(dependent variable).
Therefore, let's solve the function as follows:
f(x) = x² + 2x + 1
g(x) = x + 3
h(x) = 3x - 4
Therefore,
f(3) = (3)² + 2(3) + 1 = 9 + 6 + 1 = 16
h(0) = 3(0) - 4 = -4
h(g(x)) = 3(x + 3) - 4 = 3x + 9 - 4 = 3x + 5
g(y) = y + 3
f(x) - h(x) = x² + 2x + 1 - (3x - 4) = x² + 2x + 1 - 3x + 4 = x² - x + 5

Joe earns $25 mowing his neighbor’s lawn each week (w). He is saving his
money to buy a hoverboard that costs $168. Which inequality matches
this situation? (circle your answer)
a) $168-$25 < w b) $25w > $168 c) $25w < $168
"The correct option is (C) $25w < $168." This means that Joe needs to save for at least 7 weeks (since he can't save for a fraction of a week) to afford the hoverboard.
The hoverboard costs $168 and Joe earns $25 each week. To determine if Joe can afford the hoverboard, we need to determine how many weeks he needs to save to reach the cost of the hoverboard.
Let's represent the number of weeks Joe needs to save as "x". Each week, he earns $25, so the total amount he will have after "x" weeks is 25x. In order to buy the hoverboard, he needs to have saved $168. Thus, we can write the inequality:
25x ≥ 168
This inequality represents the fact that the amount of money Joe earns after "x" weeks must be greater than or equal to $168, the cost of the hoverboard, for him to be able to afford it. Simplifying this inequality, we get:
x ≥ 6.72.

If s5= -16.3804 and r=9/10,what is a₁?
The first term of GP is a₁ = -4.
Given that,
Sum of five terms of GP = s₅ = -16.3804
Common ratio = 9/10 which is less than 1
Number of terms = n = 5
We know that,
Sum of nth term of GP when common ration is less than 1,
s₅ = a₁(1-[tex]r^{n}[/tex])/(1-r)
Substituting the values,
⇒ -16.3804 = a₁(1-0.9⁵)/(1-0.9)
⇒ a₁ = -16.3804/4.0951
⇒ a₁ = -4
Hence, the value of a₁ is -4.

What value of x satisfies the equation −1.5x−2.7=20.1+4.5x
To solve for x in the equation −1.5x−2.7=20.1+4.5x, we need to isolate x on one side of the equation. We can do this by adding 1.5x to both sides of the equation and adding 2.7 to both sides of the equation, which gives us:
-1.5x - 2.7 + 1.5x = 20.1 + 4.5x + 1.5x
Simplifying the left side of the equation and combining like terms on the right side of the equation gives us:
-2.7 = 6x + 20.1
Subtracting 20.1 from both sides of the equation gives us:
-22.8 = 6x
Dividing both sides of the equation by 6 gives us:
x = -3.8
Therefore, the value of x that satisfies the equation is -3.8.

The values of x and y are proportional. proportionality (k) and find the missing values. 2. UX x 6 15 9 y 42 200 d. X 14 y 21 6 15 3 7 8 Determine the constant of proportionality
Step-by-step explanation:
To determine the constant of proportionality (k) in a proportional relationship, we need to compare corresponding values of x and y and calculate the ratio between them.
Let's examine the given values:
2. UX: x 6 15 9 y 42 200
To find the constant of proportionality (k), we can take any pair of corresponding values and calculate their ratio. Let's choose the first pair: (6, 42).
k = y / x
k = 42 / 6
k = 7
So, the constant of proportionality (k) is 7.
Now, let's find the missing values for the second set of values:
d. X: 14 y: 21 6 15 3 7 8
Since we know the constant of proportionality is 7, we can calculate the missing values of y by multiplying each corresponding x value by 7.
Missing values for y:
- For x = 21, y = 21 * 7 = 147
- For x = 6, y = 6 * 7 = 42
- For x = 15, y = 15 * 7 = 105
- For x = 3, y = 3 * 7 = 21
- For x = 7, y = 7 * 7 = 49
- For x = 8, y = 8 * 7 = 56
Therefore, the missing values of y are: 147, 42, 105, 21, 49, and 56.

Here,
we can see that the function C(x) = 25x + 75 represents the labor cost (in dollars) for Bob's Auto Repair to replace your alternator, where x is the number of hours. We can use this function to find the cost of replacing an alternator that is estimated to take 5 hours of labor.
C(5) = 25(5) + 75 = 125 + 75 = 200
We also have the labor cost for the main competitor, Budget Auto Repair, in a table format.
Hours Cost
1 $90
2 $130
3 $170
We can see that the cost of labor increases as the number of hours increases. From the information provided it's hard to say which company would be cheaper to hire, however the company with the function C(x) = 25x + 75 would be cheaper if the alternator takes more than 4 hours of labor, otherwise Budget Auto Repair would be cheaper.
It's important to check the warranty, prices of parts, and reputation of both companies. If a company has a good reputation and a good warranty, it may be worth paying a little more for labor.
It's also a good idea to get a second opinion or ask for a quote from both companies before making a decision.
In conclusion, it's hard to say which company would be cheaper to hire based on the information provided, but it's recommended to check the warranty, prices of parts, and reputation of both companies, and to get a second opinion or quote from both companies before making a decision.

For the line that passes through the points A(5, 8, -2) and B(-1, 3, 5), find:
a. a vector equation.
b. parametric equations.
c. Symmetric equations
The symmetric equations for the line are:
(36x + 40y - 28z - 100) / 0 = (x-5) / -6 = (y-8) / -5 = (z+2) / 7
To find the parametric equations for the line passing through A(5, 8, -2) and B(-1, 3, 5), we can use the vector equation:
r = A + t(B-A)
where r is the position vector of any point on the line, t is a scalar parameter, and A and B are the given points. Substituting the values, we get:
r = (5, 8, -2) + t((-1)-5, 3-8, 5-(-2))
r = (5, 8, -2) + t(-6, -5, 7)
The parametric equations for the line are:
x = 5 - 6t
y = 8 - 5t
z = -2 + 7t
To find the symmetric equations, we can use the fact that any point on the line is equidistant from points A and B. Thus, the distance from a point (x, y, z) to A must be the same as the distance from the same point to B. Using the distance formula, we get:
√[(x-5)² + (y-8)² + (z+2)²] = √[(x+1)² + (y-3)² + (z-5)²]
Squaring both sides and simplifying, we get:
36x + 40y - 28z - 100 = 0

The term (100 C 15) represents the number of ways to choose 15 defective screws out of 100 packs.
In a scenario where there are 2 defective screws out of 100 packs, each containing 500 screws, we can calculate the probability of obtaining 15 defective screws. Let's assume that each pack is independent of the others.
The probability of a single screw being defective is 2/500, as there are 2 defective screws out of 500 in each pack.
Conversely, the probability of a screw being non-defective is 498/500.
To find the probability of obtaining exactly 15 defective screws, we can use the binomial distribution formula. The probability (P) can be calculated as follows:
P = (100 C 15) * (2/500)^15 * (498/500)^85

Carly deposits money into a compound interest account in 2010. The equation P = 600(1.0375)
represents the amount of money in her account, P, after t years.
Determine how much money Carly has in her account in 2047. What was the growth rate?
How long does it take for Carly's account to reach $750? Round answer to the nearest tenth.
The compound interest is solved and the amount in her account in 2047 is given by A = $ 1315.46
Given data ,
To determine how much money Carly has in her account after 37 years, we need to substitute the value of t as 37 into the equation:
P = 600(1.0375)^t
P = 600(1.0375)^37
P ≈ 600(1.0375)^37 ≈ 600(2.19243) ≈ $ 1315.46
Therefore , Carly has approximately $1315.46 in her account after 37 years.
To calculate the growth rate, we need to find the rate of change between the initial and final amounts over the given time period.
Regarding how long it takes for Carly's account to reach $750, we'll assume you mean when the account reaches or exceeds $750. Let's set up the equation and solve for t:
750 = 600(1.0375)^t
Dividing both sides by 600, we get:
1.25 = 1.0375^t
Taking the logarithm of both sides (base 1.0375):
log(1.25) = t * log(1.0375)
t ≈ log(1.25) / log(1.0375) ≈ 8.5 years
Hence , it takes approximately 8.5 years for Carly's account to reach or exceed $750
