These values match the given sequence, so the function that describes the sequence is:
an = 5(2.2 + 0.8182n)ⁿ⁻¹
What is the meaning of the word "function"?According to one definition, a function is a relationship between a number of inputs where each input has exactly one output.
To find the function that describes the given geometric sequence, we need to find the common ratio r. We can do this by dividing any term in the sequence by the previous term:
11/5 = 2.2
29/11 = 2.63636...
83/29 = 2.86206...
We can see that the common ratio is increasing, which suggests that the sequence is not a perfect geometric sequence. However, the differences between the ratios are getting smaller, so we can approximate the sequence as a geometric sequence with a changing common ratio.
Let's use the first two terms of the sequence to find an initial approximation for the common ratio:
r ≈ 11/5 = 2.2
Then, we can write the nth term of the sequence as:
an = 5(2.2)ⁿ⁻¹
However, we noticed that the common ratio is increasing, so we need to adjust our formula to account for this. Let's try a formula where the common ratio is a linear function of n:
an = 5(2.2 + 0.8182n)ⁿ⁻¹
Plugging in n = 1, 2, 3, and 4, we get:
a1 = 5(2.2 + 0.8182(1))⁰ = 5
a2 = 5(2.2 + 0.8182(2))¹ ≈ 11
a3 = 5(2.2 + 0.8182(3))² ≈ 29
a4 = 5(2.2 + 0.8182(4))³ ≈ 83
These values match the given sequence, so the function that describes the sequence is:
an = 5(2.2 + 0.8182n)ⁿ⁻¹
where n is the index of the term in the sequence.

The time can be obtained from 1/0.042 * ln (p(t)/1000)
What is an exponential function?
An exponential function is a mathematical function of the form f(x) = a^x, where a is a positive constant and x is a variable. The base a is usually a number greater than 1, although it can be any positive number.
Exponential functions have a distinctive characteristic that sets them apart from other types of functions: the value of the function increases or decreases exponentially as the value of x increases or decreases. In other words, the rate of change of the function is proportional to its current value, which results in a rapid growth or decay.
We have that;
p(t) = 1000e^0.042t
p(t)/1000 = e^0.042t
ln (p(t)/1000) = 0.042t
t = 1/0.042 * ln (p(t)/1000)

Find the slope of the line through the points (-2, -8) and (8, -8)
Answer:
The two points given are (-2, -8) and (8, -8), which lie on a horizontal line. Since the line is horizontal, the slope is zero.
To see this, we can use the formula for the slope of a line between two points:
slope = (y2 - y1)/(x2 - x1)
Substituting the coordinates of the two given points, we get:
slope = (-8 - (-8))/(8 - (-2)) = 0
Therefore, the slope of the line through the points (-2, -8) and (8, -8) is 0.

a) Determine if f is continous from the left at x =0
b) Determine if f is continous from the right at x =0
c) Determine if f is continous at f = 0
"f " is continuous at x = 0.
a) To determine if f is continuous from the left at x = 0, we need to evaluate the limit of f(x) as x approaches 0 from the left. This means we need to use the first piece of the function, x + sin x, since this is the piece that applies when x < 0:
lim(x->0-) f(x) = lim(x->0-) (x + sin x) = 0 + sin 0 = 0
Since the limit exists and is equal to the value of the function at x = 0 (which is 2), f is continuous from the left at x = 0.
b) To determine if f is continuous from the right at x = 0, we need to evaluate the limit of f(x) as x approaches 0 from the right. This means we need to use the third piece of the function, 2/(1+x^2), since this is the piece that applies when x > 0:
lim(x->0+) f(x) = lim(x->0+) (2/(1+x^2)) = 2/(1+0^2) = 2
Since the limit exists and is equal to the value of the function at x = 0 (which is 2), f is continuous from the right at x = 0.
c) To determine if f is continuous at x = 0, we need to make sure that the limits from the left and right both exist and are equal to each other and to the value of the function at x = 0. We already found that the limits from the left and right are both equal to 2, which is also the value of the function at x = 0. Therefore, f is continuous at x = 0.

Irons is trying to lay out the bases for a game of kickball such that the infield is a square as shown. She would like bases to be 25 feet apart. She first placed home base and then places first and third base 25 feet from home base
How far to the nearest tenth of a foot should first base and third base be from each other justify.
The answer of the given question based on the Irons is trying to lay out the bases for a game of kickball such that the infield is a square the answer is first base and third base should be about 35.4 feet apart.
What is Pythagorean theorem?The Pythagorean theorem is fundamental concept in geometry that relates to three sides of right triangle. It states that in right triangle, the square of length of hypotenuse (the side opposite the right angle) is equal to sum of the squares of lengths of other two sides.
We can use the Pythagorean theorem to find this distance.
Let's call the distance between home base and first base "a". We know that the distance between home base and third base is also "a", because the infield is a square. We also know that the distance between home base and second base (which is the hypotenuse of the right triangle formed by home base, first base, and second base) is 25 feet.
Using the Pythagorean theorem, we can solve for "a":
a² + 25² = a² + a²
2a² = 25²
a² = (25²)/2
a = sqrt((25²)/2) ≈ 17.7 feet
So the distance between first base and third base should be approximately 35.4 feet (2a). Rounding to the nearest tenth of a foot, this is 35.4 feet. Therefore, first base and third base should be about 35.4 feet apart.

Vinne Two weeks ago, the cost to fly from to was 210$. Now the cost is 300$. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
Step-by-step explanation:
for % questions always find 100% and/or 1%.
everything else can be easily calculated out of these 2.
the original price of $210 = 100%, as we want to know how many % the new price is different from that.
100% = $210
1% = 100%/100 = 210/100 = $2.10
the new price is $300.
the difference is 300 - 210 = $90
how many % are $90 compared to the original price ?
well, as many as the times 2.1 (1%) fits into 90 :
90/2.1 = 42.85714286...%
that increase from $210 to $300 was 42.85714286...%.
an additional $50 baggage fee ?
we have to add this to the $300 and get $350 as new price.
that difference is now 350 - 210 = $140.
how many % are $140 compared to the original price ?
140/2.1 = 66.66666666...%
that increase from $210 to $350 was 66.66666666...%.
A company makes wax candles in the shape of a rectangular prism. Each candle is 5 inches long, 4 inches wide, and 7 inches tall. How much wax will they need to make 420 candles?
The company will need 58,800 cubic inches of wax to make 420 candles.
How much wax will they need to make 420 candles?To calculate the amount of wax required to make 420 candles,
We need to first calculate the volume of wax required to make one candle,Then multiply that by the total number of candles to find the total amount of wax required.The volume of a rectangular prism is given by the formula V = l x w x h, where l is the length, w is the width, and h is the height.
So, we have
V = 5 in x 4 in x 7 in = 140 cubic inches
To find the total amount of wax required to make 420 candles,
We have
Total amount of wax = 140 cubic inches/candle x 420 candles
= 58,800 cubic inches
Hence, the company needs 58,800 cubic inches

The playground at a park is shaped like a trapezoid. The dimensions of the playground are shown in the diagram.
What is the area of the playground in square feet?
A.3,120 feet2
B.1,768 feet2
C.1,560 feet2
D.3,536 feet2
Answer:
To find the area of the trapezoid-shaped playground, we need to use the formula:
Area = (1/2) × (base1 + base2) × height
In the given diagram, the length of the top base is 24 feet, the length of the bottom base is 48 feet, and the height is 52 feet.
So, the area of the playground is:
Area = (1/2) × (24 + 48) × 52
= (1/2) × 72 × 52
= 1,872 square feet
Therefore, the area of the playground is 1,872 square feet.
The closest option to this answer is option B, which is 1,768 square feet. However, the correct answer is actually 1,872 square feet.
Find all values of m for which the equation has two complex (non-real ) solutions.
The answer of values of m for which the equation has two complex (non-real) solutions are all values greater than 1/8. In other words, m > 1/8
To find all values of m for which the equation has two complex (non-real) solutions, we need to use the discriminant of the quadratic formula.
The discriminant is the part of the quadratic formula under the square root: b²-4ac. If the discriminant is less than 0, then the equation will have two complex (non-real) solutions.
So, let's start by setting the discriminant to be less than 0:
b²-4ac < 0
Now, let's plug in the values from the equation into the discriminant. The equation is in the form ax²+bx+c=0, so we can plug in the values for a, b, and c:
(1)²-4(m)(2) < 0
Simplify:
1-8m < 0
Subtract 1 from both sides:
-8m < -1
Divide both sides by -8:
m > 1/8
So, the values of m for which the equation has two complex (non-real) solutions are all values greater than 1/8. In other words, m > 1/8.

If Jason claims no allowances this year, $17 more will be deducted from his weekly check for taxes compared to last year when he claimed one allowance.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
The amount of money deducted from Jason's paycheck for taxes depends on the number of allowances he claims.
Claiming more allowances reduces the amount of taxes withheld from his paycheck while claiming fewer allowances increases it.
If Jason claimed 1 allowance last year, his employer would have withheld taxes from his paycheck based on that information.
If he claims no allowances this year, more taxes will be withheld.
To calculate how much more will be deducted from his weekly check if he claims no allowances, we need to know his tax bracket and the amount of taxes that will be withheld for each allowance.
Assuming Jason is paid on a weekly basis, we can use the IRS tax withholding tables for 2021 to estimate the additional amount of taxes that will be withheld if he claims no allowances.
Using these tables, we find that for a single person earning $232.50 per week, claiming no allowances would result in an additional withholding of $17 per week.
Therefore, claiming no allowances would result in an additional withholding of $17 per week.

There are 120 coins made up of Php 5 and Php 10 amounting to Php 950. How many of each kind of coin are there?
To solve this problem, we can use a system of equations.
Let's call the number of Php 5 coins x and the number of Php 10 coins y. The first equation will represent the total number of coins: x + y = 120. The second equation will represent the total amount of money: 5x + 10y = 950. Now we can use the elimination method to solve for one of the variables. Let's multiply the first equation by -10 and then add the two equations together:
-10x - 10y = -1200
5x + 10y = 950
-----------------
-5x = -250
Divide both sides by -5 to get x:
x = 50. Now we can plug this value back into the first equation to solve for y:

To solve this problem, use logarithmic properties to combine the two equations into one.
First, use the product rule to combine the two equations:
$\log_2(32) + \log_2(x-4) + \log_2(x) = 5$
Then use the power rule to combine the last two terms:
$\log_2(32) + \log_2(x^2 - 4x) = 5$
Finally, use the quotient rule to separate the terms:
$\log_2\frac{32}{x^2 - 4x} = 5$
To solve for $x$, take the inverse logarithm of both sides:
$\frac{32}{x^2 - 4x} = 2^5$
Expand and simplify the left side to get a quadratic equation:
$x^2 - 4x - 32 = 0$
Solve the quadratic equation using the quadratic formula:
$x = \frac{4 \pm \sqrt{4^2 + 4(32)}}{2}$
$x = \frac{4 \pm \sqrt{136}}{2}$
$x = 4 \pm \sqrt{17}$
