1. In a concert hall, the number of seats in each row increases as you move farther from the stage. There are
the first row, 38 seats in the second row, and 45 seats in the third row.
a) If this pattern continues, determine what type of sequence this represents. Then write a function rule in simplified
form that can be used to find the number of seats in the nth row. Be sure to use the correct notation you have
learned this unit. Show ALL work.
b) Use the rule to determine which row has 290 seats. Show ALL work.
According to the situation described, we have that:
a) The arithmetic sequence that gives the number of seats in the nth row is given by:
\(a_n = 24 + 7n\)
b) The 38th row has 290 seats.
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
\(a_n = a_1 + (n - 1)d\)
Item a:
The first row has 31 seats, the second has 38, the third has 45 and so on, hence:
It is an arithmetic sequence.The common difference is d = 7.The first term is \(a_1 = 31\).Then, the rule is:
\(a_n = a_1 + (n - 1)d\)
\(a_n = 31 + 7(n - 1)\)
\(a_n = 24 + 7n\)
Item b:
This is the nth row, for which \(a_n = 290\), hence:
\(a_n = 24 + 7n\)
\(290 = 24 + 7n\)
\(7n = 266\)
\(n = \frac{266}{7}\)
\(n = 38\)
The 38th row has 290 seats.

Robin dropped a lacrosse ball from a building. After each bounce the height of the ball is measured and recorded in the table. What is the height of the ball after bounce 7?
Answer:
2.5 cm
Step-by-step explanation:
From the first 4 bounces, we find that the height of the lacrosse ball after each bounce is 1/4 the height that it was after the previous bounce. Therefore, since the 7th bounce is 6 bounces after the first bounce, we can set up an equation to find the balls height (y), after some number of bounces after the first one:
\(y=10240*(\frac{1}{4})^x\).
Plug-in 6 for x to get 2.5.

What is the distance between the points (-2,1) and (5,-4)
Considering the definition of distance between two points, the distance between the points (-2,1) and (5,-4) is √74= 8.6023.
Distance between two pointsThe distance between two points is equal to the length of the segment that joins them. Therefore, to determine the distance between two different points, you must calculate the squares of the differences between their coordinates and then find the root of the sum of said squares.
In other words, the distance between two points in space is the magnitude of the vector formed by said points.
So, given the coordinates of two distinct points (x1, y1) and (x2, y2), the distance between two points is the square root of the sum of the squares of the difference of the coordinates of the points:
distance= \(\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }\)
Distance between the points (-2,1) and (5,-4)In this case, you know:
(x1, y1): (-2,1)(x2, y2): (5,-4)Replacing in the definition of distance:
distance= \(\sqrt{(5-(-2))^{2} +(-4-1)^{2} }\)
distance= \(\sqrt{(5+2)^{2} +(-5)^{2} }\)
distance= \(\sqrt{7^{2} +(-5)^{2} }\)
distance= \(\sqrt{49+25 }\)
distance= √74= 8.6023
Finally, the distance between the points (-2,1) and (5,-4) is √74= 8.6023.

You want to know the image of the point (-4, -6) after reflection in the x-axis and translation 3 left and 1 down.
Composition of transformationsThe composition ...
\(T_{-3,-1}\circ r_{\text{x-axis}}\)
is interpreted to mean reflection in the x-axis occurs first, then translation by (-3, -1).
That is, a composition of transformations is evaluated right to left.
ReflectionReflection in the x-axis moves a point from below the x-axis to the same distance above the x-axis. That is, the sign of the y-coordinate changes:
(-4, -6) ⇒ (-4, 6) . . . reflection in the x-axis

The radius of a right circular cone is increasing at a rate of 1.4 in/s while its height is decreasing at a rate of 2.4 in/s. At what rate is the volume of the cone changing when the radius is 140 in. and the height is 186 in.
Answer:
The volume is increasing at a rate of 27093 cubic inches per second.
Step-by-step explanation:
Volume of a cone:
THe volume of a cone, with radius r and height h, is given by:
\(V = \frac{1}{3} \pi r^2h\)
In this question:
We have to differentiate implictly is function of t, so the three variables, V, r and h, are differenciated. So
\(\frac{dV}{dt} = \frac{\pi r^2}{3}\frac{dh}{dt} + \frac{2\pi rh}{3}\frac{dr}{dt}\)
The radius of a right circular cone is increasing at a rate of 1.4 in/s while its height is decreasing at a rate of 2.4 in/s.
This means that \(\frac{dr}{dt} = 1.4, \frac{dh}{dt} = -2.4\)
Radius is 140 in. and the height is 186 in.
This means that \(r = 140, h = 186\)
At what rate is the volume of the cone changing?
\(\frac{dV}{dt} = \frac{\pi r^2}{3}\frac{dh}{dt} + \frac{2\pi rh}{3}\frac{dr}{dt}\)
\(\frac{dV}{dt} = \frac{\pi (140)^2}{3}(-2.4) + \frac{2\pi 140*186}{3}1.4\)
\(\frac{dV}{dt} = -0.8\pi(140)^2 + 62*2\pi*1.4*140\)
\(\frac{dV}{dt} = 27093\)
Positive, so increasing.
The volume is increasing at a rate of 27093 cubic inches per second.

Solve for x. 24= -4(x-1)
Answer:24 = 24x
Step-by-step explanation:Cross multiply:
2 * 12 = x * 24
Simplifying
2 * 12 = x * 24
Multiply 2 * 12
24 = x * 24
Reorder the terms for easier multiplication:
24 = 24x
Solving
24 = 24x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-24x' to each side of the equation.
24 + -24x = 24x + -24x
Combine like terms: 24x + -24x = 0
24 + -24x = 0
Add '-24' to each side of the equation.
24 + -24 + -24x = 0 + -24
Combine like terms: 24 + -24 = 0
0 + -24x = 0 + -24
-24x = 0 + -24
Combine like terms: 0 + -24 = -24
-24x = -24
Divide each side by '-24'.
x = 1

But still owes $120,000 on the loan.
So, 19500 - 120000
⇒ 75000
He has $5,000 in savings and a balance of $1,400 on his credit cards.
So, 75000 + 5000+ 1400
⇒ 81400
There is a balance of $20,000 owed on Ben’s car which is valued at $38,000.
So, 81400 + 38000 - 20000
⇒ 99400
Thus, Ben’s net worth is $99400.

Answer:
How to simplify this:
Arcctg(tg(x) )
The expression arcctg(tg(x)) simplifies to arcctg(tan(x)).
To simplify the expression arcctg(tg(x)), we can apply trigonometric identities and properties.
The function arcctg(x) is the inverse cotangent function, which is the angle whose cotangent is x. Similarly, tg(x) represents the tangent function.
First, let's simplify the expression inside the arcctg function, which is tg(x):
tg(x) = sin(x) / cos(x)
Now, we can substitute this value into the original expression:
arcctg(tg(x)) = arcctg(sin(x) / cos(x))
Using the property of inverse trigonometric functions, we can rewrite this as:
arcctg(sin(x) / cos(x)) = arcctg(1 / tan(x))
Now, we can simplify further using the identity:
1 / tan(x) = cot(x)
Therefore:
arcctg(1 / tan(x)) = arcctg(cot(x))
Using another identity, we know that the cotangent function is the reciprocal of the tangent function:
cot(x) = 1 / tan(x)
Therefore, we can simplify the expression to:
arcctg(cot(x)) = arcctg(1 / tan(x)) = arcctg(tan(x))
Finally, we arrive at the simplified expression:
arcctg(tg(x)) = arcctg(tan(x))

b. P(odd, even) or P(even, odd)
P(same number on both) = 10/60 = 1/6 and P(odd, even) or P(even, odd) = 1/4
How to find the probabilitiesThere are 10 possible outcomes on the 10-sided die and 6 possible outcomes on the 6-sided die
The total number of possible outcomes is 10 x 6 = 60.
To get the same number on both, we need to get one of the 10 numbers on the first toss and then get the same number on the second toss. There are 10 ways to do this. Therefore, the probability of getting the same number on both is:
P(same number on both) = 10/60 = 1/6
b. To get an odd and an even number, we need to get an odd number on the first toss and an even number on the second toss, or vice versa.
There are 5 odd numbers and 5 even numbers on the 10-sided solid, and 3 even numbers and 3 odd numbers on the 6-sided solid.
Therefore, the probability of getting an odd and an even number, or an even and an odd number, is:

Define equation? What is Equation Modelling?
Equation is defined as a relation that equates two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given are the following equations -
0 . 3 + 1 = 3.0
6.1.0 = 6 + 1 + 0
7.1 = 0 + 7
1 + 1 = 1 : 1
We have -
0 . 3 + 1 = 3.0
0 x 3 + 1 = 3 x 0
0 + 1 = 3 x 0
1 = 0
false
6 . 1 . 0 = 6 + 1 + 0
6 x 1 x 0 = 7 + 0
0 = 7
false
7 . 1 = 0 + 7
7 x 1 = 7
7 = 7
true
1 + 1 = 1 : 1
2 = 1/1
2 = 1
false
Therefore, the only true equation is 7 . 1 = 0 + 7.

Vehicles generally decrease in value around 14% per year. If you buy a vehicle priced at $39,500 , this can be modeled by the equation A=39500(0.86)t . Estimate the value of the vehicle after 4 years. Round to the nearest cent and do not round until the final calculation.
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..
To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.
Substituting t = 4 into the equation:
A = 39500(0.86)^4
A ≈ 39500(0.5996)
A ≈ 23726.20
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.
This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.
