The maximum height reached after the 13th bοunce is 6.14 cm.
What is height οf bοunce?The height οf bοunce is the height tο which an οbject rebοunds after cοIIiding with a surface, such as a baII bοuncing οn the grοund οr a diver bοuncing οff a diving bοard. The height οf the bοunce depends οn severaI factοrs, incIuding the initiaI height οf the οbject, the surface it cοIIides with, the eIasticity οf the οbject and the surface, and the angIe οf incidence.
Tο sοIve this prοbIem, we need tο use the fοrmuIa fοr the height οf each bοunce:
[tex]h = (3/4)^{{n}} \times H[/tex]
where h is the height οf the nth bοunce, H is the initiaI height (in this case, 187.00 cm), and n is the number οf bοunces.
We want tο find the maximum height reached after the 13th bοunce, which means we need tο find the height οf the 13th bοunce and then muItipIy it by 3/4 tο get the maximum height.
Using the fοrmuIa abοve, we can find the height οf the 13th bοunce:
[tex]h = (3/4)^{{13}} \times 187.00[/tex]
h ≈ 8.18 cm
Nοw we can find the maximum height:
maximum height = (3/4) × h
maximum height = (3/4) ×8.18
maximum height ≈ 6.14 cm
Therefοre, the maximum height reached after the 13th bοunce is apprοximateIy 6.14 cm.

Zoe has 7/3 of an ounce of children’s ibuprofen. A full dose for Zoe’s one-year-old is 2/5 of an ounce. To figure out exactly how many doses she has left, she drew the diagram below. But she realized that her diagram shows how many 1/5-ounce doses are in 7/3 of an ounce. How can she use her diagram to figure out how many 2/5-ounce doses she has? Explain using words and diagrams.
It should be noted that to use the diagram to figure out how many 2/5-ounce doses Zoe has, she can divide the 7/3-ounce amount into equal parts of 2/5 ounce.
How to explain the word problemOne way to do this is to divide 2/5 by 1/5 to get the number of 1/5-ounce portions that make up a 2/5-ounce dose, which is 2. Then, divide 7/3 by 2/5 to get the total number of 2/5-ounce doses she has.
So, using the diagram, Zoe can count the number of 1/5-ounce portions she has, and then divide that number by 2 to find out how many 2/5-ounce doses she has.
Alternatively, Zoe could redraw the diagram to show 2/5-ounce portions instead of 1/5-ounce portions, and then count the number of 2/5-ounce portions she has. She would need to divide the original diagram into equal parts of 2/5 ounce by drawing lines to divide each square into two parts. Then she can count the number of squares that represent a 2/5-ounce dose.

Fill in the table of value for the equation y = 2x + 1
Answer:
To fill in the table of values for the equation y = 2x + 1, we can choose different values of x and substitute them into the equation to find the corresponding values of y. For example:
x y
0 1
1 3
2 5
3 7
4 9
To get the value of y, we substitute each value of x into the equation and simplify:
When x = 0:
y = 2(0) + 1 = 1
When x = 1:
y = 2(1) + 1 = 3
When x = 2:
y = 2(2) + 1 = 5
When x = 3:
y = 2(3) + 1 = 7
When x = 4:
y = 2(4) + 1 = 9
Therefore, the table of values for the equation y = 2x + 1 is:
x y
0 1
1 3
2 5

Rapunzel was sitting in her tower and waiting for the prince to come for tea. “He’s coming in 15 1/2 minutes, so I had better hurry and tidy up. Rapunzel started cleaning and finished with 55 seconds to spare. How long did it take to clean her room
It took Rapunzel approximately 14.58 minutes to clean her room.
What is cleaning ?
Cleaning refers to the process of removing dirt, dust, and other unwanted substances from a surface or an object.
Let's start by converting the time to minutes.
15 1/2 minutes = 15.5 minutes
Let's now subtract the time she finished cleaning from the time she started cleaning:
15.5 - 0.92 = 14.58 minutes

A square wrestling mat has a perimeter of (12x−32)
feet. Write an expression in simplest form that represents the side length (in feet) of the mat.
Answer:
The perimeter of a square is given by the formula P = 4s, where s is the side length. In this case, we are given that the perimeter is (12x - 32) feet, so we can set up an equation:
P = 4s
(12x - 32) = 4s
To solve for s, we can divide both sides by 4:
(12x - 32)/4 = s
Simplifying the expression on the left:
3x - 8 = s
Therefore, the expression in simplest form that represents the side length of the square wrestling mat is 3x - 8 feet.
Answer:

What is binοmial distributiοn?Binοmial distributiοn is a prοbability distributiοn that describes the number οf successes in a fixed number οf independent trials, where each trial can οnly have twο οutcοmes: success οr failure.
Accοrding tο questiοn:
Let X be the number οf machines that need cοrrecting adjustments during a day's prοductiοn run, and let p = 0.2 be the prοbability that any οne machine needs cοrrecting.
Then, X fοllοws a binοmial distributiοn with parameters n = 6 (the number οf machines) and p = 0.2 (the prοbability οf a machine needing cοrrecting).
The prοbability οf X is:
P(X > 2) = 1 - P(X <= 2)
Tο calculate P(X <= 2), we can sum the prοbabilities οf X taking οn the values 0, 1, and 2:
P(X <= 2) = P(X = 0) + P(X = 1) + P(X = 2)
P(X = 0) = (6 chοοse 0) * 0.2⁰ * 0.8⁶ = 0.2621
P(X = 1) = (6 chοοse 1) * 0.2¹ * 0.8⁵ = 0.3932
P(X = 2) = (6 chοοse 2) * 0.2²* 0.8⁴ = 0.2621
Therefοre,
P(X <= 2)
= 0.9174
And
P(X > 2)

why does this series [tex]tan(2^{-n} )[/tex] converge?
*its a series from 2 to infinity, but there is no symbol for that.
The series [tex]\tan(2^{-n})[/tex] is convergent.
What is convergence of series?In mathematics, the cοnvergence οf a series refers tο the behaviοr οf the series' partial sums as mοre terms are added. A series cοnverges if its sequence οf partial sums apprοaches a finite limit, which is called the sum οf the series. If the sequence οf partial sums dοes nοt apprοach a finite limit, the series diverges.
The series [tex]\tan(2^{-n})[/tex] converges because of the following reasons:
As n increases, [tex]2^{-n}[/tex] becomes very small, which makes [tex]\tan(2^{-n})[/tex] close to its linear approximation. Therefore, we can use the linear approximation of [tex]\tan(2^{-n})[/tex] to estimate its value.
The linear approximation of [tex]\tan(2^{-n})[/tex] is [tex]2^{-n}[/tex], which means that [tex]\tan(2^{-n})[/tex] ≈ [tex]2^{-n}[/tex] when [tex]2^{-n}[/tex] is small.
Since the series [tex]2^{-n}[/tex] is convergent, by comparison test, the series [tex]\tan(2^{-n})[/tex] is also convergent.
Alternatively, we can also use the fact that the series tan(x) is convergent for x ∈ (0, π/2), and since [tex]2^{-n}[/tex] → 0 as n → ∞, we have [tex]\tan(2^{-n})[/tex] → tan(0) = 0, which implies that the series [tex]\tan(2^{-n})[/tex] is convergent.

Find the amount and C.I on a sum of Rs. 62500 for 1 year at 5% per annum compounded yearly.
The amount and the compound interest on a sum of Rs. 62500 are Rs. 65625 and Rs. 3125, respectively.
Calculating the amount and the compound interestGiven:
Principal amount (P) = Rs. 62500
Rate of interest (R) = 5%
Time period (t) = 1 year
Interest is compounded yearly.
Formula for calculating compound interest is given as:
A = P(1 + R/100)ᵗ
where A is the amount.
Using this formula, we can find the amount (A) after one year:
A = 62500(1 + 5/100)¹
A = 65625
Therefore, the amount after one year is Rs. 65625.
To find the compound interest, we can subtract the principal from the amount:
Compound Interest = A - P
= 65625 - 62500
= 3125
Therefore, the compound interest is Rs. 3125.

The average rate of change representing the state whose temperature is decreasing slower is given as follows:
-1.5ºF/day.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For Maine, in 9 days, the temperature fell by 13.5ºF, hence the rate is given as follows:
-13.5/9 = -1.5ºF/day.
For Connecticut, in 2.5 days, the temperature fell by 6.25ºF, hence the rate is given as follows:

Your sister has R375 000 and wants to retire. She expects to live for another 25 years, and she also expects to earn 8% on her invested funds. How much could she withdraw at the beginning of each of the next 25 years, and end up with zero in the account?
Answer:
Step-by-step explanation:
Your sister can use the formula for calculating the present value of an annuity to determine how much she can withdraw each year.
The formula for the present value of an annuity is:
PV = Payment x (1 - (1 + r)^-n) / r
Where:
- PV is the present value of the annuity
- Payment is the amount of each withdrawal
- r is the annual interest rate
- n is the number of periods (in this case, 25 years)
We can rearrange this formula to solve for Payment:
Payment = PV x r / (1 - (1 + r)^-n)
We know that your sister has R375 000 to start with, and she wants to end up with zero in 25 years. So, her present value (PV) is R375 000, and we can assume her future value (FV) is zero.
Using the future value formula, we can calculate the interest rate she needs to earn in order to end up with zero in 25 years:
FV = PV x (1 + r)^n
0 = 375000 x (1 + r)^25
(1 + r)^25 = 1
1 + r = (1)^1/25
r = 0
This means that your sister needs to withdraw all of her money over the 25 years in order to end up with zero at the end.
Her withdrawal each year would be:
Payment = PV x r / (1 - (1 + r)^-n)
Payment = 375000 x 0.08 / (1 - (1 + 0.08)^-25)
Payment = R34,028.82 per year
Your sister can withdraw R34,028.82 at the beginning of each year for the next 25 years, and she will end up with zero at the end, assuming she earns an 8% return on her invested funds.

Angela, Breanna, Christine, Debbie, and Esther are in a club and they need to pick two people to go to a
meeting. They write each person’s name on equally sized pieces of paper, put them in a hat, and mix the
papers thoroughly. Find the probability model for this chance process and use it to determine the probability
that Angela gets to go to the meeting.
So the probability that Angela gets to go to the meeting is 2/5.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain. Probability can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. It is an important concept in many fields, including mathematics, statistics, physics, and engineering, and is used to make predictions, analyze data, and make decisions under uncertainty.
Here,
There are a total of 5 people in the club, so there are 10 possible pairs of people that could be chosen to go to the meeting. Since each pair is equally likely to be chosen, the probability of any particular pair being chosen is 1/10.
To determine the probability that Angela gets to go to the meeting, we need to count the number of pairs that include Angela. There are 4 other people in the club, so there are 4 possible pairs that include Angela. Therefore, the probability that Angela gets to go to the meeting is:
P(Angela) = number of pairs that include Angela / total number of pairs

The range of function is values on the y-axis: R=[-7,2].
What is function?A function is a mathematical concept that describes the relationship between two sets of numbers. It is a rule that assigns to each input (or element in the domain) exactly one output (or element in the range). In simpler terms, a function is like a machine that takes in a number and produces another number as output, according to some specific rules. The input is usually denoted by x, and the output by f(x), which is read as "f of x". Functions can take many forms, such as linear, quadratic, trigonometric, exponential, logarithmic, and more. They are widely used in mathematics, science, engineering, and many other fields to model and analyze various phenomena.
Here,
To find the range of a function, you need to determine all possible output values of the function. Start by identifying the function's domain, which is the set of all possible input values of the function. Once you know the domain, apply the function to each input value in the domain and record the corresponding output values. Once you have a list of output values, identify the smallest and largest values in the list. These values represent the range of the function. For example, consider the function f(x) = 2x + 1. The domain of this function is all real numbers.
To find the range, apply the function to several input values in the domain:
f(-3) = -5
f(-2) = -3
f(-1) = -1
f(0) = 1
f(1) = 3
f(2) = 5
f(3) = 7
These output values give us a set of possible output values, which are {-5, -3, -1, 1, 3, 5, 7}. The smallest value in the set is -5 and the largest value is 7, so the range of the function is [-5, 7].
Note that for some functions, it may be difficult or impossible to find the exact range. In such cases, you can use techniques such as graphing or calculus to estimate the range.

Third Rock Ventures sells all its merchandise on credit. It has a profit margin of 8%, days sales outstanding were 60 days based on 360 days in a year, receivables of R180 000, total assets of R4000 000, and a debt ratio of 0,75. What is the company's return on equity (ROE)?
Answer:
Step-by-step explanation:
First, we need to calculate the company's credit sales for the year:
Credit Sales = Receivables / (Days Sales Outstanding / 360)
Credit Sales = R180,000 / (60/360) = R1,080,000
Next, we need to calculate the company's net income:
Net Income = Profit Margin x Credit Sales
Net Income = 0.08 x R1,080,000 = R86,400
We can calculate the company's total equity as follows:
Total Equity = Total Assets x (1 - Debt Ratio)
Total Equity = R4,000,000 x (1 - 0.75) = R1,000,000
Finally, we can calculate the ROE:
ROE = Net Income / Total Equity
ROE = R86,400 / R1,000,000 = 0.0864 or 8.64%
Therefore, Third Rock Ventures' return on equity is 8.64%.
