The farmer originally bought 41 pigs.
Let x be the number of pigs the farmer originally bought.The total cost of the pigs is $180.After 3 died, he was left with x - 3 pigs.He sold these pigs at a profit of $8 per pig,Resulting in a total profit of 8(x - 3).We know his total profit was $109. So, we can set up an equation:Profit = Selling price - Cost price8(x - 3) = 109 (his total profit) + 180 (cost price)
Combining like terms:8x - 24 = 289
Adding 24 to both sides:8x = 313
Dividing both sides by 8:x = 39.125
Since the farmer can't buy parts of pigs, we round x up to the nearest whole number, which is 40.However, there's a slight discrepancy because the profit wouldn't be exactly $109 if he had 40 pigs. This is because the profit is calculated per pig, and a fraction of a pig wouldn't generate a proportional profit.Therefore, let's try with x = 41:Profit = 8(41 - 3)= 8 * 38
= $304
Total earnings = Profit + Cost price= $304 + $180 = $484
Since the cost price is $180 and the total earnings are $484,The profit would be $484 - $180 = $304, This matches the calculation with 8 pigs sold at a profit of $8 each.Therefore, the farmer originally bought 41 pigs.

Answer:
If two events are mutually exclusive then they cannot occur at the same time.
Step-by-step explanation:
If two events are mutually exclusive then they cannot occur at the same time.
For example: If you take a coin, the two possible outcomes on flipping a coin will be mutually exclusive as when you flip a coin, it cannot give both heads and tails at the same time.
Hence, the two mutually exclusive events cannot occur at the same time.

Michael and Imani go out to eat for lunch. If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill?
Answer:
The bill total is $27.32
Step-by-step explanation:
how to figure out tax amount: 25.30 x .08 = $2.024
add tax to cost of meal : 25.30 + 2.024 = $27.32
To calculate the total cost of the meal including an 8% tax, multiply the cost of the meal by the tax rate and add this to the original meal cost. The tax comes to $2.02. So, the total cost of the meal, including tax, is $27.32.
Explanation:The question asks how much the total bill is for Michael and Imani when they go out to eat for lunch. The food and beverages cost $25.30 and there is an 8% meal tax. To calculate the total cost of the meal including the tax, we can multiply the cost of the meal ($25.30) by the tax rate (8%) and add this to the original cost for the meal.
First, let's convert the tax rate from a percentage to a decimal. 8% is equivalent to 0.08 as a decimal. Then, we multiply $25.30 by 0.08:
$25.30 * 0.08 = $2.02
This amount ($2.02) is the tax on the meal. To get the total cost, add this tax amount to the cost of the meal:
$25.30 + $2.02 = $27.32
So, Michael and Imani's bill, including the 8% meals tax, will be $27.32.

In the figure below, A shows the position of a house on the shore and B shows the position of a house on an island. To find the distance between the two houses,a surveyor measures from the house on shore to point C. An instrument is used to find
The surveyor is using a trigonometric method to calculate the distance between the two houses. They form a right triangle with points A, B and C, measure the length AC and the angle at point A or C, and then calculate the distance AB using trigonometric ratios.
Explanation:In this scenario, the surveyor is using a method resembling triangle-based methods in Mathematics, which specifically relates to trigonometry. To determine the distance between points A (house on shore) and B (house on island), the surveyor measures line AC, forms a right triangle ABC, and uses an instrument (like a theodolite) to measure one of the corners (usually angle at point A or C). With the measured length and angle, the distance AB can be calculated using trigonometric ratios (like sine, cosine, or tangent), depending upon the given scenario. For instance, if the angle at point A and length AC are known, then the distance AB can be calculated as AB = AC / cos(A), where A is the angle at point A.

Suppose you have $30 to spend on bags of tootsie rolls that are worth $3 and bags of lollipops worth $5. If you have to use all of their money, what combinations of candy bags can they buy?
Construct a linear equation and find/explain the y-intercept, x-intercept, and slope.
Finally, if you have $45 to spend on the candy, how would that impact everything?
Answer:
see below
Step-by-step explanation:
Let x = tootsie rolls
y = lollipops
Toosie rolls are 3 dollars and lollipops are $5 and you only have 30 dollars.
3x+5y =30
To find the x intercept, set y=0 and solve for x
3x +0 = 30
3x = 30
Divide by 3
3x/3 = 30/3
x = 10
The x intercept is 10. This means if you get no lollipops, you can have ten tootsie rolls.
To find the y intercept, set x=0 and solve for y
0 +5y = 30
5y = 30
Divide by 5
5y/5 = 30/5
x = 6
The y intercept is 6. This means if you get no tootsie rolls you can have 6 lollipops.
To find the slope, solve the equation for y
3x+5y =30
Subtract 3x from each side
3x-3x+5y = -3x+30
5y = -3x+30
Divide by 5
y = -3/5 x +30/5
y = -3/5 x +6
The slope is -3/5. For every three less lollipops you get, you can have 5 more tootsie rolls.
If you have $45 dollars instead of 30, this will change the x and y intercepts, but not the slope.
3x+5y =45
To find the x intercept, set y=0 and solve for x
3x +0 = 45
3x = 45
Divide by 3
3x/3 = 45/3
x = 15
The x intercept is 15. This means if you get no lollipops, you can have 15 tootsie rolls.
To find the y intercept, set x=0 and solve for y
0 +5y = 45
5y = 45
Divide by 5
5y/5 = 45/5
x = 9
The y intercept is 9. This means if you get no tootsie rolls you can have 9 lollipops.
To find the slope, solve the equation for y
3x+5y =45
Subtract 3x from each side
3x-3x+5y = -3x+45
5y = -3x+45
Divide by 5
y = -3/5 x +45/5
y = -3/5 x +9
The slope is -3/5. For every three less lollipops you get, you can have 5 more tootsie rolls.
Solve the system of equations in three variables
We start from the third equation:
4z = 16 divide both sides by 4
z = 4Put the value of z to the second equation:
y + 4 = 5 subtract 4 from both sides
y = 1Put the values of y and z to the first equation:
3x + 2(1) - 4 = 4
3x + 2 - 4 = 4
3x - 2 = 4 add 2 to both sides
3x = 6 divide both sides by 3
x = 2Keiko makes 8 dollars for each hour of work. Write an equation to represent her total pay p after working h hours.
Answer:
8h = pStep-by-step explanation:
So if p is the total amount paid, and h is the amount of time spent working, it'll be worked out something like this.
The amount of money she makes per hour x the amount of time spent working = the amount she is paid.
Thus making it...
8 x h = p
but in algebra expressions, we don't normally use arithmetic symbols. So if we get rid of that, we get the answer of 8h = p.

Answer:
D. f^-1(x) = log2(x -6)4x^2 -3 . . . . x ≤ 0B. √(x^5) -3√(x^3) -18√xStep-by-step explanation:
1. When you replace f(x) by x and x by y, you have
... x = 2^y + 6
The first thing you do is subtract 6; then you take the base-2 logarithm:
... (x -6) = 2^y
... log2(x -6) = y = f^-1(x)
You know that to get the y-term by itself, you must subtract 6. Anything else you do will operate on (x-6). Only answer choice D has that sort of construction.
2. When you swap x and y and solve for y, you have ...
... x = -1/2√(y+3)
... -2x = √(y +3) . . . . . . multiply by -2
... (-2x)^2 = y +3 . . . . . square
... 4x^2 - 3 = y = f^-1(x) . . . . subtract 3
The range of f(x) is (-∞, 0], so that is the domain of f^-1(x). That is, f^-1(x) is defined for x ≤ 0.
3. The product of the two functions is ...
... (x -6)(√x)(x +3) = (√x)(x^2 -3x -18)
Every term will have a factor of √x, and the coefficients will be 1, -3, -18. Only selection B matches those conditions.
Answer:
Question One: log_2(x - 6) = y
Question Two: First blank: 4 Second blank 0
Question Three: B
Step-by-step explanation:
f(x) = 2^x + 6
y = 2^x + 6 Interchange the x and y
x = 2^y + 6 Subtract 6 from both sides
x - 6 = 2^y Take the log of both sides
log(x - 6) = log 2^y The power can be multiplied by the log of 2
log(x - 6) = y log(2) Divide by the log of 2
log(x - 6)/log(2) = y This to me is the preferred answer. It allows you to calculate what the actual number is or graph it on Desmos
The answer I have given is equivalent to using base 2 as your log, but calculating that is not always easy.
log_2(x - 6) = y
Answer: D
Problem Two
You want the inverse of y = - 1/2 sqrt(x + 3) x ≥ - 3
Note: you cannot have any number less than -3 because if you do, you will be taking the square root of -x which involves complex numbers. In addition x ≥ -3 is a domain. You have to keep that in mind when doing this question.
y = - 1/2 sqrt(x + 3) Interchange the x and yx = - 1/2 sqrt(y + 3) Multiply by - 2-2x = sqrt(y + 3) Square both sides(-2x)^2 = sqrt(y + 3)^2 4x^2 = y + 3 Subtract 3 from both sidesy = 4x^2 - 3The domain and range of this is a little harder to figure out. The range of f(x) becomes the domain of f-1(x)
The range of f(x) is 0 <=y < - infinity
So the domain of f-1(x) <= 0
Answer: The first blank is 4 and the second one is 0
Graph: the graph is given you below the question. What it shows is the f(x) and f^-1(x) are symmetrical about y = x. Most inverses are. If you want to check your work, it is best to include a graph when doing inverses.

The best way to begin this problem is to apply the associative property of multiplication and start by rewriting the givens as x^(1/2)[(x - 6)(x + 3)]. Do what is in the square brackets first.
x^(1/2) [x^2 - 6x + 3x - 18]x^(1/2) [x^2 - 3x - 18]Now deal with the x^(1/2) which must be multiplied by all three terms in the square brackets.
x^(1/2)*x^2: x^(2 + 1/2) = x^(4/2 + 1/2) = x^(5/2)x^(1/2)*(-3x): - 3 x^(2/2 + 1/2) = - 3x^(3/2)x^(1/2)*(-18): - 18x^(1/2)Result: x^(5/2) - 3x^(3/2) - 18x^(1/2)

Answer:
72,220 inches per minute
Step-by-step explanation:
A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches.
1 revolution = [tex]2\pi[/tex] radians
[tex]\frac{theta}{tome}=\frac{1000 \ revolution}{1 \ minuite} = \frac{1000* 2\pi }{1} =\frac{2000\pi}{1 \ minute}[/tex]
Speed [tex]V= \frac{r*theta}{t}[/tex]
r is the radius , theta is the angle and t is the time
We know diameter = 23 , then radius = 23/2
Speed [tex]V= \frac{23}{2}*\frac{2000\pi}{1}[/tex]
Value of pi = 3.14
speed = 23000* 3.14= 72220 inches/ minute

The amount of data left on a cell phone plan is 6 GB after 8 days. 1.5 GB of data is used each day. How much data is available at the beginning of the cycle?
Answer:
The answer is 18 GB
Step-by-step explanation:
Okay to the breakdown:
This is a word problem that requires basic knowledge of equality.
So lets say that the total amount of data at the beginning of the cycle is equal to X.
We are told that the data has been used for 8 days at a daily rate of 1.5GB per day, so the total data already used will be "Days × Rate" => 8 × 1.5 = 12GB.
We are also made to know that after the 8 days we still have 6 GB left out of the initial amount X.
Let put all the above in an equation:
X - 12 = 6;
Using the approach of putting liked them together we will add 12 to both sides:
X -12 + 12 = 6 + 12 => X = 18;
So the amount at the beginning of the cycle is 18 GB.

Compare the graph of the function, g(x)=(1)/(x-1)-3(, with the graph of its parent function. ) Which of the following options best describes the transformations undergone by g(x)? Select all that apply.
left 1
up 3
right 1
left 3
down 3
up 1
right 3
Answers:
right 1, down 3 (these two answers only)
Step-by-step explanation:
There are two transformations going on. The first of which is the horizontal or x translation (aka shifting) where the 'x' turns into 'x-1'. This moves the xy axis 1 spot to the left, giving the illusion that the graph moves 1 unit to the right.
The "-3" at the end shifts the graph down 3 units. If g(x) = f(x) - 3, then g(x) is the output of f(x) but 3 less than that, which is why it shifts down 3 units.
The function g(x) represents two transformations from its parent function f(x) = 1/x: a horizontal shift to the right by 1 unit and a vertical shift down by 3 units.
Explanation:When comparing the graph of the function g(x) = (1)/(x-1) - 3 with its parent function f(x) = 1/x, the transformations undergone by g(x) include:
The addition of -1 inside the parentheses with the independent variable x, which shifts the graph to the right by 1 unit.The subtraction of 3 from the entire expression, which translates the graph down by 3 units.These transformations can be understood with the help of given examples. For instance, adding or subtracting a number to/from the independent variable x, like f(x+1), results in a horizontal shift of the graph. Multiplying the independent variable by a number, say 2 as in f(2x), would cause a horizontal compression of the graph. In our case, since the function g(x) includes x-1, it is indicating a horizontal shift to the right, and since the -3 is subtracted from the entire function, it denotes a vertical shift downward.
