What function models the height of the periscope lens at time (variable it t)? If the periscope reaches its maximum height after ascending for 22 seconds, what is the maximum height?
The answer is:
The height function modeled by the periscope is h(t) = 24 + 6 × t.The maximum height is 156 inches.The given parameters are:
Start = 24 inches
Rate = 6 inches/second
The function model of the height is determined using a linear function:
h(t) = Start + Rate × t
Where: t represents the time in seconds
So, we have:
h(t) = 24 + 6 × t
This gives
h(t) = 24 + 6t
After 22 seconds, the height of the periscope will be
h(22) = 24 + 6 × 22
Multiply
h(22) = 24 + 132
Add
h(22) = 156
Hence, the maximum height is 156 inches.

How do you plot and label points on a coordinate plane?.
Two parallel lines called the x axis and the y axis are employed for graph or plot points. The x axis is on the horizontal number line, while the y axis is on the vertical line. The positive and negative axes of the x axis are arranged to the right and left of the origin, respectively.
The following format is employed to plot a point's coordinates: (x, y). As is evident, the x-coordinate is frequently placed first. For example, we have determined the x and y coordinates for the respective points B and D in the diagram we have been using. Point B's x-coordinate is 100.
Any position on the plane may have its x- and y-coordinates established using its horizontal and vertical distances from the origin. In essence, what we do when we sketch a point is the complete antithesis of what we do here.
Labelling:
Our x-coordinate is as follows:
Positive if it's in the appropriate area of our plane.
If it is on the left side of our plot, it is not ideal.
If it is on the x-axis, then it is 0.
Our y-coordinate is as follows:
If it is in the top part of our plot, it is a good indicator.

The first two numbers in a sequence a are a(1) = 3 and a(2) = 12. If a is an arithmetic sequence, write a definition for the nth term of a. Explain or show your reasoning.
The formula of the nth term in the arithmetic sequence is a(n) = 3 + (n-1)9.
An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a fixed constant, called the common difference, to the preceding term.
The sequence can be represented by the general term an = a1 + (n-1)d, where a1 is the first term and d is the common difference
In an arithmetic sequence, the difference between consecutive terms is constant. Therefore, if a(1) = 3 and a(2) = 12, the common difference (d) is 12 - 3 = 9.
The nth term of an arithmetic sequence is given by the formula:
a(n) = a(1) + (n-1)d
where:
a(n) is the nth term of the sequence
a(1) is the first term of the sequence
d is the common difference
n is the position of the term in the sequence
So, for the given sequence, the nth term a(n) of the arithmetic sequence is:
a(n) = a(1) + (n-1)d = 3 + (n-1)9
This means that the nth term of the arithmetic sequence is found by adding the common difference (9) to the first term (3), and then multiplying the result by (n-1) which indicates the position of the term in the sequence.
Therefore, a(n) = 3 + (n-1)9 is the formula of the nth term in the arithmetic sequence.

Why is it called logarithm?.
The word "logarithm" is derived from the Greek meanings for "ratio" (logos) and "number" (arithmos).
In the 17th century, Scottish mathematician John Napier (1550-1617) developed logarithms as a tool for computing. He derived the phrase from the Greek words for ratio (logos) and number (arithmos).
Before mechanical (and later electronic) computers were developed, logarithms were essential for simplifying calculations in astronomy, navigation, surveying, and afterwards engineering. A logarithm is a mathematical formula that calculates how many times the base, or initial number, must be multiplied by itself to produce the target number. As a result of the relationship between logarithms and geometric progressions.
