Question 3 A 44-metres long fire-fighting ladder is leaned against a building, as shown in the diagram. The base of the ladder is 7 metres from the building and 3 metres above the ground. How high on the building will the ladder reach?
The ladder will reach a Height of approximately 43.46 meters on the building.
To find out how high on the building the ladder will reach, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the ladder forms a right triangle with the ground and the building. The base of the ladder is 7 meters, the height of the building is what we need to find, and the length of the ladder is given as 44 meters.
Using the Pythagorean theorem, we can set up the equation:
(Height of the building)^2 + 7^2 = 44^2
Simplifying the equation, we have:
(Height of the building)^2 + 49 = 1936
Subtracting 49 from both sides, we get:
(Height of the building)^2 = 1887
To find the height of the building, we take the square root of both sides:
Height of the building = √1887
Calculating the square root of 1887, we find that the height of the building is approximately 43.46 meters.
Therefore, the ladder will reach a height of approximately 43.46 meters on the building.

Show ALL your work here
Answer:
Step-by-step explanation:
2x - 5y = -11
ordered pair: (-5, -1)
x = -5 y = -1
plug into the equation.
2(-5) - 5(-1) = -11
a negative x a positive = a negative
2 x -5 = -10
a negative x a negative = a positive
-5 x -1 = 5
-10 + 5 = -11
5 ≠ 11
therefore its NOT solution.
. Read the paragraph and choose a sentence that describes it best. On the way across the Aegean Sea, Caesar was kidnapped by pirates and held prisoner. He maintained an attitude of superiority throughout his captivity. The pirates demanded a ransom of 20 talents of silver, but he insisted that they ask for 50. After the ransom was paid, Caesar raised a fleet, pursued and captured the pirates, before imprisoning them. He had them crucified on his own authority, as he had promised while in captivity—a promise that the pirates had taken as a joke.
a) Caesar was a vane man who thought 20 talents is too little of a ransom
b) Caesar was very brave and kept to his word to kill the pirates
c) Pirates didn’t believe Caesar will kill them because he was their prisoner
d) The pirates didn’t kill Caesar not only because he was promised to be paid for, but because he made them respect him
The sentence that best describes the paragraph is: "The pirates didn't believe Caesar would kill them because he was their prisoner." So, the correct option is c) Pirates didn’t believe Caesar will kill them because he was their prisoner.
The paragraph recounts the events of Caesar's kidnapping by pirates while crossing the Aegean Sea. Despite being held captive, Caesar maintained an attitude of superiority. The pirates demanded a ransom of 20 talents of silver, but Caesar insisted they ask for 50. This indicates that Caesar saw himself as more valuable than the initial ransom amount suggested by the pirates.
After the ransom was paid, Caesar did not forget the pirates' actions. He raised a fleet, pursued the pirates, and captured them. The sentence implies that the pirates didn't believe Caesar would actually kill them because he was their prisoner and they likely saw his promises as mere jest.
However, Caesar, true to his word, had the pirates crucified on his own authority.
This sequence of events highlights Caesar's determination, strategic thinking, and his ability to command respect even in dire circumstances. Despite being initially taken prisoner, he managed to turn the tables on the pirates, assert his authority, and exact his revenge. So, the correct option is c) Pirates didn’t believe Caesar will kill them because he was their prisoner.

Question 2:
Both parts are solved below:
Step-by-step explanation:
Given:
Purchase price = 150
Part A
As the online trailer marks up 30% so the price would be:
= 150 + 30% of 150
=150 + 0.3(150)
= 150 + 45
Price online= $195
° ♡ ₒ ♡ °
Part B
As the superstore marks up the price by 40% so the price would be:
= 150 + 40% of 150
=150 + 0.4(150)
= 150 + 60
Price at superstore = $210
° ♡ ₒ ♡ °
Difference
Difference = price at superstore - price online
Difference = 210 - 195
Difference = $15
Difference in markup = 40% - 30% = 10%
So a 10% difference leads to the difference of $15 in price.

Explain in words how you would graph the following inequality on a number line. 3x < 12 HELPPPPPPPPPPP PLSSSSSS
Answer:
x<4
Step-by-step explanation:
3x < 12
Divide with 3 on each side
x< 4
In words x has all the real numbers that are less than 4 or x belongs to any number from -ve infinity to 4.
The graph of the inequality 3x < 12 on a number line would consist of an open circle at 4, followed by a shaded region to the left of 4 and extending indefinitely in that direction.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
To graph the inequality 3x < 12 on a number line, we can follow these steps:
- Start by isolating x by dividing both sides of the inequality by 3, which gives us x < 4.
- Draw a number line and mark a point at 4, which is the boundary between the values of x that satisfy the inequality and those that don't.
- Since the inequality is strict (i.e., "less than" and not "less than or equal to"), we need to indicate that the point x = 4 is not included in the solution set.
We can do this by making an open circle (or "unfilled dot") at 4 on the number line.
- Shade the portion of the number line to the left of the point x = 4, since these are the values of x that satisfy the inequality 3x < 12.
We can use an arrow pointing to the left to indicate that the shaded region extends indefinitely in that direction.
Thus,
The graph of the inequality 3x < 12 on a number line would consist of an open circle at 4, followed by a shaded region to the left of 4 and extending indefinitely in that direction.

What are the solutions to the equation 0=|3x+3|+3
Therefore, the solutions to the equation 0 = |3x + 3| + 3 are x = -2 and x = 0.
To solve the equation 0 = |3x + 3| + 3, we need to eliminate the absolute value. Remember that the absolute value of a number is always non-negative.
First, let's isolate the absolute value term on one side of the equation:
|3x + 3| = -3
Since the absolute value cannot be negative, there are no solutions to the equation as it stands. However, if we modify the equation to make the right side positive, we can find a solution.
To eliminate the absolute value, we can rewrite the equation as two separate equations, considering both the positive and negative cases:
3x + 3 = -3
-(3x + 3) = -3
Solving equation 1:
3x + 3 = -3
3x = -6
x = -2
Solving equation 2:
-(3x + 3) = -3

By integrating, the function is f(θ) = -sin(θ) - cos(θ) + θ + 6
What is relationship between integrals and derivatives?
The derivative and the integral are related to each other through the fundamental theorem of calculus:
If f(x) is a continuous function on an interval [a, b], then the function F(x) defined by F(x) = ∫[a, x] f(t) dt is continuous on [a, b] and differentiable on (a, b), and F'(x) = f(x). This means that the derivative of the integral of a function is equal to the original function.
To find f(θ), we need to integrate f''(θ) twice.
f''(θ) = sin(θ) + cos(θ)
Integrating once gives:
f'(θ) = -cos(θ) + sin(θ) + C₁
Using the initial condition f'(0) = 2, we have:
f'(0) = -cos(0) + sin(0) + C₁ = 1 + C₁ = 2
Therefore, C₁ = 1, and we have:
f'(θ) = -cos(θ) + sin(θ) + 1
Integrating again gives:
f(θ) = -sin(θ) - cos(θ) + θ + C₂
Using the initial condition f(0) = 5, we have:
f(0) = -sin(0) - cos(0) + 0 + C₂ = -1 + C₂ = 5
Therefore, C₂ = 6, and we have:
f(θ) = -sin(θ) - cos(θ) + θ + 6
So, the function f(θ) is:
f(θ) = -sin(θ) - cos(θ) + θ + 6
And f''(0) is:
f''(0) = sin(0) + cos(0) = 1

a tuxedo rental service charges $150 flat fee for a suit plus $50 per additinal day. The total cost of the tuxedo is $300. How many days was the tuxedo rental for?
The tuxedo was rented for 4 days.
Let's start by assigning variables to the unknowns. Let "x" be the number of additional days rented, and "d" be the total number of days rented (including the first day).
From the given information, we know that the flat fee for the rental is $150, so the cost of the additional days is the total cost minus the flat fee, which is $300 - $150 = $150. We also know that the cost for each additional day is $50. Therefore, we can set up the equation:
$150 + $50x = $300
Subtracting $150 from both sides, we get:
$50x = $150
Dividing both sides by $50, we get:
x = 3

What makes an equation with a single unknown helpful in one of your examples but not the other?
The required, In simpler problems with a single variable and clear constraints, an equation with a single unknown variable can be very helpful. In more complex problems with multiple variables and complex relationships, more advanced mathematical tools may be necessary to find a solution.
What is the equation model?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
An equation with a single unknown variable can be helpful in situations where we need to find the value of that variable that satisfies certain conditions or constraints. For example, if we know the area of a square and we need to find the length of one of its sides, we can use an equation with a single unknown (in this case, the length of one side of the square) to solve for that variable.
On the other hand, an equation with a single unknown variable may not be helpful in situations where the problem involves multiple variables or complex relationships between variables. For example, if we need to optimize a manufacturing process that involves multiple variables, such as temperature, pressure, and flow rate, we may need to use a system of equations or more advanced mathematical tools to find the optimal values for each variable.
