The formula for compound interest is:
where A is the total amount, p is the principal invested, r is the interest rate as a decimal number, n is the number of times per year the interest is compounded, and t is the number of years.
The principal in this problem is 25,000; the interest rate is 3% = 3/100 = 0.03; the number of times the interest is compounded is 4; and the number of years is 8:
Which one of the following is not a power equation?
p= v2/r= vxi
p= v2xi p= i2xr
The equation that is not a power equation is p = v²×i
Power equationsFrom the question, we are to determine which of the given equations is not a power equation
Where the Voltage, V, and the Current, I, are given, the power, P is given by
P = IV
When the Voltage and the Resistance, R, are given
P = V²/R
When the Current and the Resistance are given,
P = I²R
∴ P = V²/R, P = IV, and P = I²R are power equations.
Hence, the equation that is not a power equation is p = v²×i

The numbers of seats in the first 16 rows in a curved section of another arena form an arithmetic sequence. If there are 20 seats in Row 1-23 seats in Row 2, how many seats are in Row 16?
The total number of seats are there is row 16 is 65.
What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between two different arithmetic orders is a fixed number (AP). Arithmetic Sequence is another name for it.
We'd come along through a few specific terms in AP that had been labeled as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP can also be referred to in terms of common differences.
The following is the procedure for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, as the values given in the question;
There are total 16 rows in the arena.
Thus, n = 16.
There are 20 seats present in row 1.
Consider the first term as 'a₁' = 20.
Similarly, there are 23 seats present at row 2.
Consider 'a₂' = 23 is the second term.
Now, calculate the common difference;
d = a₂ - a₁
Put the values in the 'd'.
d = 23 - 20 = 3.
Now, compute the total number of seats in 16th row bu nth formula.
n-th term: an = a + (n − 1) × d
a₁₆ = a₁ + (n - 1)d
a₁₆ = 20 + (16 - 1)3
a₁₆ = 20 + 45
a₁₆ = 65
Therefore, the total number of seats present in the 16th row is 65.

log_(2) (sqrt((2+14 )*(1+3))
The value of the expression is 3 using the concept of the logarithm.
A base must be raised to a certain exponent or power, or logarithm, to produce a specific number. If bˣ=n, then x is the logarithm of n to the base a, which is expressed mathematically as x = logₐ n.
Given the expression log₂√(2+14)(1+3)
Solving the square root we obtain,
[tex]log_{2} \sqrt{(16)(4)}\\[/tex]
Simplifying further we get,

c. What is the mode subscription fee?
d. If Marshal is looking to add another subscription how much would it have to be so the mean

subscription is exactly $7 per month?
For the given subscriptions, we have that:
a) The mean is of $6.42.
b) The median is of $5.
c) The modes are of 5 and 10.
d) Marshall would have to add a subscription of $12.25.
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
For this problem, the observations are given as follows:
10, 5, 10, 4, 12, 5, 6, 2.75, 3.
Hence the mean is:
M = (10 + 5 + 10 + 4 + 12 + 5 + 6 + 2.75 + 3)/9 = $6.42.
With another observation, we want a mean of $7, hence:
(10 + 5 + 10 + 4 + 12 + 5 + 6 + 2.75 + 3 + x)/10 = 7
57.75 + x = 70
x = 12.25.
Hence, for item d:
Marshall would have to add a subscription of $12.25.
What is the median?The median of a data-set is the middle value, which is the value that 50% of the data-set is greater and 50% is lesser.
The ordered data-set in this problem is:
2.75, 3, 4, 5, 5, 6, 10, 10, 12.
The middle value is of 5, which is the median.
What is the mode of a distribution?The mode of a distribution is the observation that appears the most times in the distribution.
In this problem, those observations are 5 and 10, both of which appears twice, hence the distribution is bimodal.

Using supplementary angles, it is found that the value of x is of x = 10.75.
What are supplementary angles?Supplementary angles are angles whose measures add to 180º.
An entire pizza is 360º, hence half the pizza is 180º, meaning that angles AOB and BOD are supplementary.
Their measures are given as follows:
m<AOB = 2x - 4.m<BOD = 14x + 12.Since they are supplementary, they add to 180º and we can add their measures and solve for x as follows:
2x - 4 + 14x + 12 = 180

What is the meant by the term distributive property?To "distribute" something means to divide it or give a fraction or portion of it.The distributive property corresponds to the distributive law of multiplication over basic arithmetic operations such as addition and subtraction.This property states that multiplying a sum of two or even more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.In other words, the distributive property requires an expression of the form: A (B + C) can be written as AB + BC.This property also applies to subtraction: A (B - C) can be written as AB - BC.This indicates that other two operands share operand A.From the given options;
Consider option D; 15 + 40 = 5(3 + 8).
It is the case of distributive addition.

Write the equation of the circle that passes through the given point and has a center at the origin. (Hint: You can use the distance formula to find the radius.) (-6,-4)
The equation of the circle that passes through the point (-6 , -4) and has a center located at the origin is x^2 + y^2 = 52.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-6 , -4).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(-6 - 0)^2 + (-4 - 0)^2
radius= √36 + 16
radius = √52
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = √52

I will mark brainliest!
we can't say that "both square roots for 16, the area of the square, are the length of each side of the square"
Because one of these solutions does not have a meaning in the given contest.
Why is the statement incorrect?So we have a square with an area of 16 square units, then the side length of that square will be given by:
S^2 = 16 square units
Now, there are two solutions for the above equation, these are:
S = 4 units
S = -4 units.
But being a solution of the equation does not mean that the solutions have sense in the context of the problem.
When we talk about dimensions of figures, negative numbers are not really well defined. We can't say that a square has a side length of "negative 4 units"
That does not make sense, remember that math is just a language, and it should be used to communicate things to others.
So the logical solutions (4 and -4) is not the only thing we need to look at when we state the solutions of a problem, but also the problem itself.

A bouncy ball is dropped such that the height of its first bounce is 6.5 feet and each successive bounce is 78% of the previous bounce's height. What would be the height of the 10th bounce of the ball? Round to the nearest tenth (if necessary).
Answer:
Approximately [tex]0.7\; {\rm ft}[/tex].
Step-by-step explanation:
If the current bounce is of height [tex]h\; {\rm ft}[/tex], the next bounce would be of height [tex](78\%\, h)\; {\rm ft}[/tex], which is equal to [tex](0.78\, h)\; {\rm ft}[/tex].
It is given that the first bounce is of height [tex]6.5\; {\rm ft}[/tex]. Relative to this first bounce:
The [tex]n = 2[/tex] bounce is dampened [tex](2 - 1) = 1[/tex] time. The height of this bounce would be [tex]((0.78)\, 6.5)\; {\rm ft} = ((0.78)^{2 - 1} \, 6.5)\; {\rm ft}[/tex].The [tex]n = 3[/tex] bounce is dampened [tex](3 - 1) = 2[/tex] times. The height of this bounce would be [tex](0.78)\, ((0.78)\, 6.5)\; {\rm ft} = ((0.78)^{3 - 1} \, 6.5)\: {\rm ft}[/tex].In general, the [tex]n[/tex]th bounce would have been dampened [tex](n - 1)[/tex] times. The height of that bounce would be [tex]((0.78)^{n - 1}\, 6.5)\; {\rm ft}[/tex].
Thus, the [tex]10[/tex]th bounce would have been dampened [tex](10 - 1) = 9[/tex] times. The height of that bounce would be [tex]((0.78)^{10 - 1} \, 6.5)\; {\rm ft} \approx 0.7\; {\rm ft}[/tex] (rounded to the nearest tenth, one digit after the decimal point.)
