The length of a rectangle is 4 ft longer than its width. If the perimeter of the rectangle is 32 ft, find its area.
Answers
To find the area of a rectangle, we need to know its length and width. Let's solve the problem step by step:
Let's assume that the width of the rectangle is represented by "w" (in feet).
According to the given information, the length of the rectangle is 4 feet longer than its width, which means the length can be represented as "w + 4" (in feet).
The perimeter of a rectangle is calculated by adding up all the sides. In this case, the perimeter is given as 32 feet.
Since a rectangle has two pairs of equal sides (length and width), we can express the perimeter equation as the following:
2(length + width) = perimeter
Substituting the values into the equation, we get:
2(w + (w + 4)) = 32
Simplifying the equation, we have:
2(2w + 4) = 32
4w + 8 = 32
4w = 24
w = 6
Now we know that the width of the rectangle is 6 feet. To find the length, we can substitute this value back into the equation for the length:
Length = w + 4 = 6 + 4 = 10 feet
The width is 6 feet, and the length is 10 feet. Now we can calculate the area of the rectangle:
Area = Length × Width = 10 × 6 = 60 square feet
Answer: The area of the rectangle is 60 square feet.
Diseases tend to spread according to the exponential growth model. In the early days of AIDS, the growth factor (i.e. common ratio; growth multiplier) was around 1.9. In 1983, about 1600 people in the U.S. died of AIDS. If the trend had continued unchecked, how many people would have died from AIDS in 2003?
Answers
First, let's calculate the number of years between 1983 and 2003:
2003 - 1983 = 20 years
Using the exponential growth formula:
N = N0 * (growth factor)^t
Where:
N0 is the initial value (number of deaths in 1983)
(growth factor) is the common ratio or growth multiplier
t is the time in years
Given:
N0 = 1600 (number of deaths in 1983)
growth factor = 1.9 (common ratio)
t = 20 (years)
Using the formula, we can calculate:
N = 1600 * (1.9)^20
Calculating this expression:
N ≈ 1600 * 6.1917364224
N ≈ 9907.58
Therefore, if the trend had continued unchecked, approximately 9908 people would have died from AIDS in the U.S. in 2003.
peter is 24 years younger than his father. In 5 years time, his father will be 3 times as old as peter? a). how old is peter. b). how old will peter's father be in 25 year's time?
Answers
Step-by-step explanation:
Let Peter's present age be "p" and his father's age be "x"
So, p = x-24 ;
5 years from now,
Peter's age will be (x-24) + 5 = x-19
His father's age will be x+5.
It is given that 3(x-19)= x+5.
3x - 57 = x + 5 => 2x = 62.
On solving, his father's present age (x) is 31.
So Peter's present age is (p) is x - 24 = 31 - 24 = 7.
Now going in the reverse oder to check the answer.
Peter's present is 7.
5 years from now, it will be 12.
His father's age is 31.
5 years from now, his age will be 36 (which is 3x12).
Hence , the answer to the given problem is 7

What is the average rate of change in f(x) on the interval [5,9]?
A)-1.5
B)6/4
C)4
D)-6
Answers
Answer:
A) -1.5
Step-by-step explanation:
We can find the average rate of change of a function over an interval using the formula:
(f(x2) - f(x1)) / (x2 - x1), where
(x2, f(x2)) is the rightmost part of the interval. In this problem, 9 is our x2 and f(x2) is 3 since 3 is the y-coordinate when you plug in 9 for f(x))(x1, f(x1)) is the leftmost part of the interval of the interval.In this case, 5 is our x1 and f(x1) is 9 since 9 is the y-coordinate when you plug in 5 for f(x).Thus, we can plug in (9, 3) for (x2, f(x2)) and (5, 9) for (x1, f(x1)) to find the average rate of change in f(x) on the interval [5,9].
(3 - 9) / (9 - 5)
(-6) / (4)
-3/2
is -3/2.
If we convert -3/2 into a normal number, we get -1.5
Thus, the average rate of change in f(x) on the interval [5,9] is -1.5
Answer:
Step-by-step explanation:
The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
[tex]\boxed{\textsf{Average rate of change}=\dfrac{f(b)-f(a)}{b-a}}[/tex]
In this case, we need to find the average rate of change on the interval [5, 9], so a = 5 and b = 9.
From inspection of the given graph:
f(5) = 9f(9) = 3Substitute the values into the formula:
[tex]\textsf{Average rate of change}=\dfrac{f(9)-f(5)}{9-5}=\dfrac{3-9}{9-5}=\dfrac{-6}{4}=-1.5[/tex]
Therefore, the average rate of change of f(x) over the interval [5, 9] is -1.5.

Triangle ABC has the following coordinates: A=(5,-5), B=(3,-3), C=(5,-3) What are the coordinates of triangle A'B'C' if it is created by dilating triangle ABC with the origin (0,0) as the center of dilation and with a scale factor of 3?
Answers
Answer:A' = (15, -15), B' = (9, -9), and C' = (15, -9)
Step-by-step explanation:
To dilate triangle ABC with a center of dilation at the origin (0,0) and a scale factor of 3, you need to multiply the coordinates of each vertex by the scale factor.
Let's calculate the coordinates of triangle A'B'C':
For point A:
x-coordinate of A' = scale factor * x-coordinate of A = 3 * 5 = 15
y-coordinate of A' = scale factor * y-coordinate of A = 3 * (-5) = -15
Therefore, A' = (15, -15)
For point B:
x-coordinate of B' = scale factor * x-coordinate of B = 3 * 3 = 9
y-coordinate of B' = scale factor * y-coordinate of B = 3 * (-3) = -9
Therefore, B' = (9, -9)
For point C:
x-coordinate of C' = scale factor * x-coordinate of C = 3 * 5 = 15
y-coordinate of C' = scale factor * y-coordinate of C = 3 * (-3) = -9
Therefore, C' = (15, -9)
Hence, the correct coordinates of triangle A'B'C' are A' = (15, -15), B' = (9, -9), and C' = (15, -9).
Ki Tae uses 54 meters of fencing to make a 6-sided outdoor dog pen. Two of the sides of the dog pen are each 15 meters long. The remaining 4 sides each have the same length.
Answers
Ki Tae used 54 meters of fencing to construct a 6-sided outdoor dog pen. Two of the sides are each 15 meters long, while the remaining four sides are each 6 meters long.
Let's solve the problem step by step. We know that Ki Tae used a total of 54 meters of fencing to construct a 6-sided outdoor dog pen. Two of the sides have a length of 15 meters each.
Let's denote the length of the remaining four sides as "x."
Since the dog pen has six sides, we can set up an equation based on the total length of the fencing:
15 + 15 + x + x + x + x = 54
Simplifying the equation, we have:
30 + 4x = 54
Subtracting 30 from both sides, we get:
4x = 24
Dividing both sides by 4, we find:
x = 6
Therefore, each of the remaining four sides has a length of 6 meters.

Answers
The estimated population of the state in the year 2022 is 19,280,700 people.
The given equation represents the population of a certain state as a function of time, where p is the population in thousands of people and t is the number of years since 2010.
The equation is given as p = 80.7t + 18,312.3.
To estimate the population of the state, we substitute the value of t into the equation. For example, if we want to estimate the population in the year 2022 (12 years since 2010), we substitute t = 12 into the equation:
p = 80.7(12) + 18,312.3
= 968.4 + 18,312.3
= 19,280.7.
The estimated population of the state in the year 2022 is 19,280,700 people.
We can estimate the population for any given year by substituting the corresponding value of t into the equation.
It's important to note that the population is given in thousands of people, so we multiply the final result by 1,000 to obtain the population in actual numbers.

Dylan's mom told him that she would replace each one of his dimes with a quarter. If he uses all of his coins, determine if Dylan would then have enough money to buy a game priced at $20.98 if he must also pay an 8% sales tax.
Answers
First, we need to know the initial value of Dylan's dimes and the number of dimes he has. Since the value of a dime is $0.10, we'll assume that each dime is worth $0.10.
Let's say Dylan initially has "x" dimes. Therefore, the initial value of his dimes would be 0.10x.
Now, since his mom replaces each dime with a quarter, the value of each quarter is $0.25. So, the value of his quarters would be 0.25x.
The total value of his coins after the replacement would be the sum of the initial value of dimes and the value of quarters, which is 0.10x + 0.25x = 0.35x.
Now, to determine if Dylan has enough money to buy the game priced at $20.98, we need to consider the 8% sales tax. To calculate the total amount including tax, we multiply the game price by (1 + tax rate):
Total amount including tax = $20.98 * (1 + 0.08) = $22.65.
Now, we can set up an inequality to check if Dylan has enough money:
0.35x ≥ $22.65.
Dividing both sides of the inequality by 0.35, we get:
x ≥ $22.65 / 0.35.
x ≥ $64.71.
Therefore, Dylan would need to have at least $64.71 worth of dimes (before replacement) in order to have enough money to buy the game after his mom replaces each dime with a quarter.
Note: If Dylan has fewer dimes, the total value of his coins would be lower, and he would not have enough money to buy the game.

Second, factor the parts of the fraction:
[1 / [3 · (x - 1) · (x +1)]] / [5 / (x + 1) - (x + 4) / [(x - 4) · (x + 1)]]
[1 / [3 · (x - 1) · (x +1)]] / [[5 · (x - 4) - (x + 4)] / [(x - 4) · (x + 1)]]
Third, eliminate the rational fraction:
[(x - 4) · (x + 1)] / [- 120 · (x - 1) · (x + 1)]
Fourth, eliminate common binomials:
- (x - 4) / [120 · (x - 1)]
