If the present value of an item is P
and we experience an inflation rate
of r for t years, what will the future
value of the item be?
P = $100
r = 4%
t = 15
Answers
inflation means, the same item costs more however is the same item, so if a tomato in January 1st costs $1 and by December 31st it costs $2, the price went up by twice, however is same tomato, it didn't become twice as large, anyhow, inflation eats away value and thus is a Decay case.
[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &100\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=\textit{elapsed time}\dotfill &15\\ \end{cases} \\\\\\ A=100(1 - 0.04)^{15}\implies A=100(0.96)^{15}\implies A\approx 54.21[/tex]
now, we can look at this value reduction as value that was eaten away from the original.
we can also see the inflationary effect as the new value of the tomato in money terms, that means the tomato went up in price, exponentially by 4% per year, so we can see that as a Growth case in terms of money spent on it.
[tex]\qquad \textit{Amount for Exponential Growth} \\\\ A=P(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &100\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=\textit{elapsed time}\dotfill &15\\ \end{cases} \\\\\\ A = 100(1 + 0.04)^{15} \implies A \approx 180.09[/tex]
now, this is how much the tomato will be priced in money terms in 15 years.
Crispy Clover, a popular vegetarian restaurant, introduced a new menu that has 20% more dishes than the previous menu. The previous menu had D dishes. Which of the following expressions could represent how many dishes Crispy Clover's new menu has?
Answers
Answer:
D*1.2 (OR) 1.2D
Step-by-step explanation:
Because the new menu has one hundred percent of the original menu (D), plus twenty percent, the new menu is 120%, or 1.2
You can then multiply the number of items on the original menu (D), by the new menu's value, which is 1.2 (or 120%).
This brings you to the answer of 1.2D

Using the uniform distribution, considering that the novel has 435 pages, the probability that the page is numbered something between 21 and 31 is:

Answer:
Graph of Modulus
The graph of a modulus or absolute value function is in a form of a 'V' shape whose vertex depends upon the coordinates. The equation for the graph is given as,
where,
(a, b) are the coordinates of the vertex of 'v' in the form of (x, y),
And h shows how wider or lean will be the function, for h=0, it is a straight line, while for a negative value the graph will face downwards and opposite for a positive value.
Given to us
y = |x-3|
On the coordinate plane
The graph will be in the shape of a 'V' whose vertex will lay at the coordinates (3, 0). As the value of a is 1 the graph will face upwards. As shown below on the graph.

Cynthia beach wants to buy a rug for a room that is 22 ft wide and 31 ft long.she wants to leave a uniform strip of floor around the rug.she can afford to buy 580 square feet of carpeting.what dimensions should the rug have?
Answers
The dimensions the rug should have is 20 by 29
How to determine the dimension?The dimension of the rug is given as:
22 ft by 31 ft
The area of the carpet is given as:
Area = 580
Represent the length of the empty space with x.
So, the dimension of the carpet is:
22 - 2x by 31 - 2x
The area is calculated as:
Area = (22 - 2x) * (31 - 2x)
Expand
Area = 682 - 62x - 44x + 4x^2
Evaluate the difference
Area = 682 -106x + 4x^2
Substitute Area = 580
682 -106x + 4x^2 = 580
Subtract 580 from both sides
102 -106x + 4x^2 = 0
Rewrite as:
4x^2 - 106x +102 = 0
Using a graphing calculator, we have:
x = 1 and x = 22.5
Substitute these values in 22 - 2x by 31 - 2x
So, we have:
Length = 22 - 2(1) = 20 or Length = 22 - 2(22.5) = -23
Width = 31 - 2(1) = 29 or Length = 31 - 2(22.5) = -14
The dimensions cannot be negative.
So, we have:
Length = 20 and Width = 29
Hence, the dimensions the rug should have is 20 by 29

find the perimeter of a triangular field whose length of edges are 14 m, 12m 10 m Also find the length of required to fence 4 times around it?
Answers
Answer: 36 m, 144 m
Step-by-Step Explanation:
a = 14 m
b = 12 m
c = 10 m
Perimeter = a + b + c
Therefore,
= a + b + c
= 14 + 12 + 10
= 26 + 10
=> 36
Perimeter = 36 m
Length of Fence required for Fencing 4 times = Perimeter * 4
Therefore,
= Perimeter * 4
= 36 * 4

Length of Fence required for Fencing 4 times = 144 m

We can now analyze each option using the above highlight

Alphabets = 26Probability of vowel = 5/26Probability of consonant = 21/26The probabilities of vowels and consonant are not equal.
Hence, this situation is not fair

Hence, this situation is fair
Situation 4
Numbers = 5 i.e. 2 to 6P(Prime) = 3/5P(Composite) = 4/6The probabilities of prime and composite numbers are not equal.

The probability that the dart lands inside the square but not on the circular dartboard is 22% option first is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
A dartboard consists of a circle inscribed in a square.
The area of the square is 64 square inches.
We know the area of the square:
A = a²
a is the side of the square.
64 = a²
a = 8 inches
As the circle inscribed in a square.
The diameter will be 8 inches
The radius of the circle r = 8/2 = 4 inches
Area of the circle = πr² = π(4)² = 16×3.14 = 50.24 inches
P(dart will land on circular dartboard) = 50.24/64 = 0.785
P(dart will not land on circular dartboard) = 1 - 0.785 = 0.215
or
P(dart will not land on circular dartboard) = 21.5% ≈ 22%
Thus, the probability that the dart lands inside the square but not on the circular dartboard is 22% option first is correct.
