Ten women sit in 10 seats in a line. All of the 10 get up and then reseat themselves using all 10 seats, each sitting in the seat she was in before or a seat next to the one she occupied before. In how many ways can the women be reseated
Women can be seated in 89 ways.
Let Sn be the number of possible seating arrangements with n women. Consider n≥3 and focus on the rightmost woman. If she goes back to her seat, then there are Sn−1 ways to seat the remaining n−1 women. If he is sitting in the penultimate seat, then the woman who was sitting there before must now sit in the rightmost seat.
This gives us Sn−2 ways to seat another n−2 woman, so we get the recursion Sn=Sn−1+Sn−2. Starting with S1=1 and S2=2 we can calculate S10=89.

This question only requires to to substitute t = 0 and t = 1 into the equation to find the displacement.
Lets find the displacement at t = 0.
[tex]x(0)=4sin(\pi (0)+\frac{\pi }{2} )\\=4sin(\frac{\pi }{2} )\\= 4m[/tex]
Lets find the displacement at t = 1.
[tex]x(1) = 4sin(\pi (1)+\frac{\pi }{2} )\\=4sin(\pi +\frac{\pi }{2} )\\=-4m[/tex]
Total displacement = Final Position - Initial Position

One angstrom is the tenth billionth part of a meter. express this information in scientific notation
The scientific notation for the given information is 1 × [tex]10^{-10}[/tex]. Thus, one angstrom is written as 1 × [tex]10^{-10}[/tex] and denoted by A°.
How to write in scientific notation?Scientific notation is used to write very large numbers or very small numbers in a simple way that is easy to understand and easy for calculate.
A number is written in scientific notation as follows:
Scientific notation: m × [tex]10^n[/tex]
where m is the absolute value of the number or a decimal number and n is the power and 10 is the base.
Expressing the given information in scientific notation:The given information is,
One Angstrom = ten billionths part of a meter
Since ten billion = [tex]10^{10}[/tex]
So, ten billionth part of a meter = 1 ×1/[tex]10^{10}[/tex] = 1 × [tex]10^{-10}[/tex].

5.2 x 10²
5 x 10to the power of-2
7.4 x 10 to the power of 10
1.138 x 10to the power of6
Carter's salary is $1.1138⁶ more than Salma's salary.
How much larger is Carter's salary than Salma's?To perform the difference, we need to be able to take a common factor.
We know that Salma's salary is $6.2×10⁴
While Carter's salary is $1.2×10⁶
To get the same common factor, 10⁴, we can divide and multiply Carter's salary by 100, so we get:
[tex]1.2*10^6*\frac{100}{100} = (1.2*100)*(10^6/100) = 120*10^4[/tex]
Then Carter's salary is $120*10⁴
The difference between Carter's and Salma's salaries is:
$120*10⁴ - $6.2×10⁴ = $113.8*10⁴
If we return to the scientific notation, we get:
$113.8*10⁴ = $1.1138⁶
This means that Carter's salary is $1.1138⁶ more than Salma's salary.

A college student takes the same number of credits each semester. Before beginning college, the student had some credits earned while in high school. After 3 semesters, the student had 41 credits, and after 6 semesters, the student had 68 credits. If C(t), is the number of credits after t semesters, write the equation that correctly models this situation.
Answer:
C(t) = 9t + 14
Step-by-step explanation:
write two equations with the given information
x + 6y = 68
x + 3y = 41
(x and y are just random variables, with x being the number of credits from high school and y being the number of credits earned each semester)
subtract (x+3y=41) from (x+6y=68) to get 3y=27
y = 9
then plug back in to one of the equations to find x
x + 3(9) = 41
x + 27 = 41
x = 14
then write the equation for C(t)
C(t) = 9t + 14
because you start with 14 credits from high school then add 9 credits for each semester taken

In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, when x = 0, y = 2, hence the y-intercept is of b = 2. When x increases by 1, y decreases by -8, hence the slope is of m = -8, and the rule is given by:

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Sine rule is used to show the relationship between the sides and angles of a triangle.
In the triangle XYZ:
∠X + ∠Y + ∠Z = 180° (sine rule)
22 + 39 + ∠Y = 180
∠Y = 119°
Using sine rule:
XY / sinZ = XZ / sinY
XY / sin(39) = 29 / sin(119)
XY = 20.9
Also:
YZ / sinX = XZ / sinY
YZ / sin(22) = 29 / sin(119)

Keep the triangle that you created in part A. You will now copy the triangle to a different location on the grid using three of its sides:
In a different place on the grid, draw a new line segment that is parallel to and has the same length as AB. Label this segment DE.
Next, copy AC and BC . A reliable way to do this is to draw a circle centered on each endpoint of your new line segment. Make the radius of each circle equal to each of the lengths of the two remaining line segments on the original triangle. One of the intersection points of the two circles marks the third vertex of your new triangle. Place a point on the intersection, and label the point F.
Finish copying the triangle by drawing a polygon through the three points that you've established.

A cylindrical tank with radius 3 m is being filled with water at a rate of 4 m3/min. How fast is the height of the water increasing (in m/min)
Answer:
Let R be the radius of the tank, H(t) the height of the water at time t, and V(t) the volume of the water. The quantities V(t), R and H(t) are related by the equation
V(t) = πR²H(t) ___(1)
The rate of increase of the volume is the derivative with respect to time,
dV/dt
and the rate of increase of the height is
dH/dt
We can therefore restate the given and the unknown as follows
Given:
dV/dt = 4m³/min
Unknown:
dH/dt
Now we take derivative of each side of (1) with respect to t:
dV/dt = πR²dH/dt
So
dH/dt = 1/πR²dV/dt
Substituting R = 3 m and dV/dt = 4m³/min we have
dH/dt = 1/π(3)² ⋅ 4 = 4/9π
Answer: the height of the water increasing at a rate of
dH/dt = 4/9π²
