The operations, along with their inverses are given as follows:

The operations are solved applying the inverse operations.

The first operation is solved as follows:

x + 10 = 25

x = 25 - 10

x = 15.

Hence the addition operation was solved applying the subtraction operation, which is the inverse operation of the addition.

The second operation is solved as follows:

2x = 28

x = 28/2

x = 14.

Hence the multiplication operation was solved applying the division operation, which is the inverse operation of the multiplication.

The third operation is given as follows:

4^x = 64.

log4(4^x) = log4(64)

x = 3. (as 4³ = 64, hence log4(64) = 3).

Hence the exponential operation was solved applying the logarithm operation, which is the inverse operation of the exponential.

What is compound interest?

Compound interest, also known as interest on principal and interest, is the addition of interest to the loan or deposit principal.

One plus the annual interest rate raised to the number of compound periods minus one is multiplied by the initial loan amount, or principal, to determine compound interest.

Given:

Jessica puts away $200 a month for 20 years.

P = $200

t = 20 years

r = 6% = 0.06

n = 12 (compounded monthly)

Consider the compound interest formula,

[tex]A = P(1+\frac{r}{n})^n^t[/tex]

Plug the values of P, r, n and t in the above equation.

⇒

[tex]A = 200(1+\frac{0.06}{12})^1^2^*^2^0\\ A = 200(1+0.005)^2^4^0\\A = 200(1.005)^2^4^0\\A = 662.04089\\A = 662.04[/tex]

Hence, the amount after 20 years is $662.04.

Now to find the interest does she earn.

Interest = Principle x time x rate

             = 200 x 20 x 0.06

Interest = $240

Hence, the interest does she earn is $240.

The depth of the river is 3.192 feet.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

Since last year the depth of the river was 4.2 feet deep and year it dropped 24%. The depth will be:

A formal power series that encodes the coefficients of a sequence of numbers is a generating function.

Here, the coefficients of the sequence {Sₙ} are encoded by the generating function S(x). where Sₙ is the number of lattice paths as described above.

Here we will use the fact that the generating function for a sequence satisfies a functional equation that relates the generating function to the sequence itself to prove that 1 + (x – 1)S(x) + xS(x)² = 0,

Here, the functional equation is

S(x) = 1 + xS(x) + xS(x)²

This equation implies that

The term 1 on the right-hand side corresponds to the fact that to reach the point (0,0) (the starting point), there is exactly one way which is to stay at the starting point.

The term xS(x) corresponds to the fact that by taking a step in the positive x-direction and then following a path to (n-1, n-1) we can reach any point (n,n)

The term xS(x)² corresponds to the fact that by taking a step in the positive x-direction and then following a path to (n-2, n-2), and then taking another step in the positive x-direction and following a path to (n-1, n-1) we can reach any point (n,n)

To find the Fourier cosine series of the function f(x), we first need to find the Fourier coefficients of f(x).

The Fourier coefficients of f(x) are given by:

an = (2/L) * integral of f(x) * cos(npix/L) from x=0 to x=L

bn = (2/L) * integral of f(x) * sin(npix/L) from x=0 to x=L

The rock will take 10.25 seconds to hit the ground, as the amount determined by the formula h=352-16t^(2).

The given equation is h=352-16t^(2). This equation can be used to calculate the time it will take for a rock to hit the ground after it has been dropped from a tower that is 352 feet high. The equation states that the rock's height (h) is equal to 352 minus 16 times the square of the time (t). To find the time it will take for the rock to hit the ground (h=0), we can rearrange the equation to solve for t. The rearranged equation is t=sqrt((352-0)/16), which simplifies to t=10.25. This means that the rock will take 10.25 seconds to hit the ground. This can also be expressed in tenths of a second as 102.5, which is the same as 10.25 seconds.

To find the probability that Y1 = 71 and Y2 = y2, we need to consider the possible values of X1 and X2 that could lead to these values of Y1 and Y2. The probability density functions (PDFs) of an exponential distribution with mean 1000 is f(x) = 1/1000 * e^(-x/1000). Therefore, the probability of this event is

Another possibility is that X1 = y2 and X2 = 71. The probability of this event is

Since these two events are mutually exclusive and exhaust all possible ways that Y1 can equal 71 and Y2 can equal y2, the probability of these events occurring is the sum of these probabilities. Therefore,

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

According to the given question:

Assume you have a fair coin, which means it will likely land tails up 50% of the time and heads up 50% of the time. Let's say you flip it three times, each time independently. What is the likelihood that it will land heads up first, followed by a tails up landing?

The solution is 1/8, or 12.5%.

coin flipped = 3 times.

probability of getting three heads = 0.125
