after simplifying the expression sinx + cotx cosx, we get the result as cosec x.
We are given the expression:
sinx + cotx cosx
We need to simplify the expression.
We know that cot x can also be written as
cot x = cos x / sin x
Substituting it in the expression, we get that:
= sin x + ( cos x / sin x ) cos x
opening the brackets, we get that:
= sin x + cos² x / sin x
= (sin² x + cos² x ) / sin x
Using the trigonometric identity that sin² x + cos² x = 1, we get that:
= 1 / sin x
= cosec x
Therefore after simplifying the expression sinx + cotx cosx, we get the result as cosec x.

Work out the volume of the prism height of 12 4 and five
The calculated volume of the prism is 702 cubic cm
Finding the volume of the prismFrom the question, we have the following parameters that can be used in our computation
The trapezoidal prism (see attachment)
The formula of the volume of a trapezoidal prism is
Volume = Base area * Height
Where we have
Base area = 1/2 * (8 + 10) * 6
Evaluate the sum of 8 and 10
Base area = 1/2 * 18 * 6
Evaluate the products of 1/2, 18 and 6
Base area = 54
Also, we have
Height = 13
So, the volume is calculated as
volume = 13 * 54
Evaluate
volume = 702
Hence, the volume of the prism is 702 cubic cm

Consider the system described below with input f(t) and output y(t). Determine if the system is linear or nonlinear. Show all work. dy +3 +3ty(t)=1² f(t) dt 5. By direct integration find the Laplace transform of the signal shown. f (t) 1+6) t(s)
The system described above is nonlinear because it contains a term with y(t) multiplied by t. The Laplace transform of f(t) is (6/s²)+(1/s).
If we substitute y1(t) and y2(t) into the equation and add them together, we get:
dy1/dt + 3 + 3ty1(t) = 1² f(t) dt dy2/dt + 3 + 3ty2(t) = 1² f(t) dt
Then we can add these two equations together to get:
d(y1+y2)/dt + 3 + 3t*(y1+y2)(t) = 2*1² f(t) dt
This is not equal to the original equation with y(t), which means that the system is nonlinear.
To find the Laplace transform of f(t), we can use the formula:
L{f(at+b)} = (1/a) ×F(s-b/a)
where F(s) is the Laplace transform of f(t). In this case, we have:
f(t) = (1+6t)
So we can rewrite this as:
f(t) = (6×t+1)
Now we can use the formula to find the Laplace transform:
L{(6×t+1)} = (6/s²)+(1/s)
Therefore, the Laplace transform of f(t) is (6/s²)+(1/s).

You pick a marble, roll a die, and pick a card. How many outcomes are possible?
The total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.
How to determine How many outcomes are possibleTo determine the number of possible outcomes, we need to consider the number of outcomes for each event and then multiply them together.
1. Picking a marble: Let's assume there are n marbles to choose from. If there are n marbles, then the number of outcomes for this event is n.
2. Rolling a die: A standard die has 6 sides numbered 1 to 6. Therefore, the number of outcomes for this event is 6.
3. Picking a card: A standard deck of cards has 52 cards. Hence, the number of outcomes for this event is 52.
To find the total number of possible outcomes, we multiply the number of outcomes for each event together:
Total number of outcomes = (number of outcomes for picking a marble) × (number of outcomes for rolling a die) × (number of outcomes for picking a card)
Total number of outcomes = n × 6 × 52
Therefore, the total number of possible outcomes is given by the expression 6n × 52, where n represents the number of marbles to choose from.

The percentage that can be filled with $3 in 1990 is: 29.41%
How to solve percentage increase problems?To calculate percentage growth rate:
Beginning:
Calculate the difference (increase) between the two numbers you are comparing. after that:
Divide the increment by the original number and multiply the result by 100. Growth rate = increment / original number * 100.
We are told that it cost $3 to fill a gas tank as at 1970.
Now, there was a percentage price increase of (78.8 - 23.1)% = 55.2% from 1970 to 1990. Thus:
Cost of a gallon in 1970 = $0.36
Thus, number of gallons bought with $3 = 3/0.36 = 8.33 gallons at full tank
Now, in 1990, the cost is $1.23 and as such:
Quantity that can be bought = 3/1.23 = 2.45 gallons
Percentage of tank filled = 2.45/8.33 * 100% = 29.41%

Determine the seating capacity of an auditorium with 35 rows of seats if there are 20 seats in the first row, 25 seats in the second row, 30 seats in the third row, 36 seats in the fourth row, and so on.
Total number of seats=_____.
The total number of seats in the auditorium is 3500.
What is the arithmetic series?
An arithmetic series is a sequence of numbers in which the difference between any two consecutive terms is always the same. It can also be defined as a sum of a finite number of terms of an arithmetic progression.
The seating capacity of the auditorium can be found by using the formula for the sum of an arithmetic series.
The formula for the sum of an arithmetic series is:
S = n/2 (2a + (n-1)d)
Where:
S is the sum of the series (total number of seats)
n is the number of terms in the series (number of rows of seats)
a is the first term in the series (number of seats in the first row)
d is the common difference between terms in the series (increase in number of seats per row)
In this case,
a = 20 (number of seats in the first row)
d = 25 - 20 = 5 (increase in number of seats per row)
n = 35 (number of rows of seats)
So,
S = 35/2 (2(20) + (35-1)(5))
S = 35/2 (40 + 160)
S = 35/2 (200)
S = 35*100
S = 3500
Hence, the total number of seats in the auditorium is 3500.

Last week Forrest cut the grass exactly 3 times. It takes him between 55 and 75 minutes per cut.
CWrite an inequality to model all of the possible amounts of time (t) Forrest could have spent
cutting the lawn last week. Show or explain all your work.
Explanation:
If he mowed the lawn exactly once, then 55 ≤ t ≤ 75 describes all the possible values of t. Basically t is between 55 and 75 inclusive of both endpoints.
Multiply each value by 3
55*3 = 165
75*3 = 225
That's how we end up with 165 ≤ t ≤ 225 to represent the possible span of time values where he mowed the grass three times. His fastest possible time is 165 minutes (2 hr, 45 min) and his slowest possible time is 225 minutes (3 hr, 45 min).
Edwin sells jars of jam for $1.90 each. Determine how many jars of jam Edwin needs to sell to break even if the variable cost per jar is $1.10 and fixed expenses are $35,700.00 per year.
Edwin needs to sell 44,625 jars of jam to break even.
To determine how many jars of jam Edwin needs to sell to break even, we'll calculate the breakeven point using the following formula:
Breakeven Point = Fixed Expenses / (Selling Price per Unit - Variable Cost per Unit)
Given information:
Selling Price per Unit (SP) = $1.90
Variable Cost per Unit (VC) = $1.10
Fixed Expenses = $35,700.00 per year
Plugging in the values into the formula:
Breakeven Point = $35,700 / ($1.90 - $1.10)
Breakeven Point = $35,700 / $0.80
Breakeven Point = 44,625 jars
Therefore, Edwin needs to sell 44,625 jars of jam to break even.

Ana works 25 hours a week at the library. If she is paid $10 an hour, and her net salary each week is $212.50, what percent of her salary is withheld for taxes?
Approximately 17.65% of Ana's salary is withheld for taxes.
To calculate the percentage of Ana's salary that is withheld for taxes, we need to determine the amount of tax withheld and then express it as a percentage of her net salary.
Number of hours worked per week (H) = 25 hours
Hourly wage (W) = $10
Net salary (S) = $212.50
Calculate the total earnings before taxes:
Total earnings = Hours worked * Hourly wage
Total earnings = 25 hours * $10/hour
Total earnings = $250
Determine the amount of tax withheld:
Tax withheld = Total earnings - Net salary
Tax withheld = $250 - $212.50
Tax withheld = $37.50
Calculate the percentage of salary withheld for taxes:
Percentage withheld = (Tax withheld / Net salary) * 100
Percentage withheld = ($37.50 / $212.50) * 100
Percentage withheld ≈ 17.65%
Therefore, approximately 17.65% of Ana's salary is withheld for taxes.

Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9
I'm more confident with x=4 and y=2 because of the small size of the triangle.
