every year 5 rows and 5columns are increased . derive the formula for the number of students in each row
The number of students in each row after any number of years, as long as the increase in rows and columns is uniform every year.
Assuming that the increase in rows and columns is uniform every year, we can derive the formula for the number of students in each row as follows:
Let's start with the initial number of rows and columns, which we'll call R0 and C0, respectively, and the number of students in each row, which we'll call S.
After one year, the number of rows and columns will increase by 5, so we'll have R1 = R0 + 5 and C1 = C0 + 5. The total number of students will be R1 x S. We can also express this in terms of the initial number of rows and columns as:
R1 x S = (R0 + 5) x S
Expanding the brackets, we get:
R1 x S = R0 x S + 5 x S
Subtracting R0 x S from both sides, we get:
(R1 - R0) x S = 5 x S
Dividing both sides by 5 x (R1 - R0), we get:
S = 5 / (R1 - R0)
We can use this formula to calculate the number of students in each row after any number of years, as long as the increase in rows and columns is uniform every year.

The value of x in the trapezoid is 2.
How to find the side of a trapezoid?The mid points of a trapezoid is a line that goes across from the middle of one leg to the middle of the other leg.
Using the mid point theorem, let's find the value of x in the trapezoid as follows:
PS = 1 / 2 (QR + TU)
PS = x + 33
QR = -6x + 37
TU = 2x + 41
Therefore,
x + 33 = 1 / 2 (-6x + 37 + 2x + 41)
x + 33 = 1 / 2 (-4x + 78)
x + 33 = -2x + 39
x + 2x = 39 - 33

The value of sin(θ) is 0.31 and it lies in the third and fourth quadrants. if the value of the cosine of θ is −0.95.
cos(θ) = -0.95
To calculate the value of sin(θ), we can use the Pythagorean theorem:
[tex]sin^{2}[/tex] (θ) +[tex]cos^{2}[/tex] (θ) = 1
We can rearrange the Pythagorean identity to solve for sin(θ):
[tex]sin^{2}[/tex] (θ)= 1 - [tex]cos^{2}[/tex]
sin(θ) = ±[tex]\sqrt{1-cos^{2}}[/tex] *(θ)--------- (equation 1)
Substitute the value of the cosine of θ = −0.95 in Equation 1
sin(θ) = ±[tex]\sqrt{1-cos^{2}}[/tex] *(θ)
sin(θ) = ±[tex]\sqrt{(1 - 0.9025)}[/tex]
sin(θ) = ±[tex]\sqrt{0.0975}[/tex]
The positive value determines that the value is in the first and second quadrants, Negative shows the third and fourth quadrants.

OC. The number of years between adjustments in the interest rate
D. The interest rate of the initial, fixed-rate loan period

As far as a 5/1 ARM is concerned, note that the "1" refers to how often the rate can be adjusted after the initial fixed-rate period ends.
What is 5/1 ARM?A 5/1 ARM is an adjustable rate mortgage loan (ARM) that has a fixed interest rate for the first five years. Following that, the 5/1 ARM transitions to an adjustable interest rate for the remainder of its term. The terms "variable" and "adjustable" are frequently used synonymously.
If you want a low monthly payment and don't expect to stay in your house for long, a 5/1 adjustable-rate mortgage (ARM) loan may be worth considering. For the first five years, rates on 5/1 ARMs are typically lower than rates on 30-year fixed-rate mortgages.

The chambered nautilus is a fascinating marine animal that belongs to the family of cephalopods.
It is notable for its unique, spiral-shaped shell that is divided into a series of chambers.
The nautilus lives in the outermost chamber of its shell, which it can control by adjusting the amount of gas and fluid inside it. This allows the nautilus to regulate its buoyancy and move up or down in the water column.
The nautilus has been around for millions of years and is sometimes called a "living fossil" because of its ancient lineage.

Find the y intercept for a line with a slope or 2 that goes through (5, 4)
Answer:
y- intercept = - 6
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here slope m = 2 , then
y = 2x + c ← is the partial equation
to find c substitute (5, 4 ) into the partial equation
4 = 2(5) + c = 10 + c ( subtract 10 from both sides )
- 6 = c
that is the y- intercept c = - 6
