The Pythagoras is the sum of the square of two sides is equal to the square of the longest side. The height of the house is 12 feet, then the correct option is B.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
Miguel places his 13-foot ladder 5 feet from the edge of his house.
Then the height of the house is given by the Pythagoras theorem.
P² = H² - B²
P² = 13² - 5²
P² = 169 - 25
P² = 144
P = 12
Then the height of the house is 12 feet.

Find the value of x and the value of y.
A. x = 16, y = 9V2
B. x = 7, y = 16 V2
C. x= 16V/, y = 7.12
D. x= 7/3, y = 16
Answer:
[tex]A.\ ~~x=16,~ y=9\sqrt{2}[/tex]
Step-by-step explanation:
We have completed the diagram with some lengths that come directly from the figure's symmetry.
Note the triangle formed at the left side of the trapezium is isosceles because it has an angle of 90° and another angle of 45°.
This means the base of the triangle has the same length as the height of 9.
This means the total base of the trapezium is x = 9 + 7 = 16
The right triangle must satisfy Pythagora's Theorem:
[tex]y^2=9^2+9^2[/tex]
[tex]y^2=2*9^2[/tex]
[tex]y=\sqrt{2*9^2}[/tex]
Simplifying the radical:
[tex]y=9\sqrt{2}[/tex]
The correct answer is: [tex]\mathbf{A.\ ~~x=16,~ y=9\sqrt{2}}[/tex]

Find the product (у- 2)(5у2 + 3y - 1)
Answer:
5y^3 - 7y^2 - 97y + 2 <<<< Answer
Step-by-step explanation:
(у- 2)(5у2 + 3y - 1)
Multiply the three terms by y
5y^2 * y + 3y * y - 1*y = 5y^3 + 3y^2 - y
Multiply the three terms by - 2
-2*5y^2 -2*3y - 2*-1
-10y^2 - 6y + 2
Now combine the like terms
5y^3 + 3y^2 - 10y^2 - y - 6y + 2
5y^3 - 7y^2 - 97y + 2

One degree of longitude at the equator is approximately 111 km. As we move north or south the size of a degree changes. How many kilometers would 1° of longitude measure in kilometers at 45° latitude north? A. 55.5 kilometers B.222 kilometers C. 444 kilometers D. 0 kilometers
Answer:
B.
Step-by-step explanation:
55.5 kilometers would be 1° of the longitude measure in kilometers at 45° latitude north.
What are longitude and latitude?Latitudes are horizontal lines that indicate how far away from the equator a location is. Longitudes are vertical lines that represent the east and west directions relative to Greenwich, England's meridian. Cartographers, geographers, and others can pinpoint points or locations on the globe by combining latitude and longitude.
Given, At the equator, one degree of longitude is around 111 kilometers. The size of a degree fluctuates as we go north or south. since the equator is perpendicular to the pole. which is 90 degrees hence it's asking distance of 45 therefore from the proportionality concept in a right angle triangle. the distance at 1 is at 45 latitudes is 111/2 or 55.5.
Therefore, At 45° latitude north, 55.5 kilometers would represent 1° of the longitude measurement in kilometers.

In the rectangular prism, PQ is the diagonal. Find the length of
PQ given PR = 7, RS = 4, and QS = 4.
A 4
B 9
C 12
D 15
Answer:
Option (B)
Step-by-step explanation:
Length of PR = 4
RS = 4
QS = 4
For the length of PT,
PT² = RT² + PR² [Since, PT is the diagonal of rectangle PRT]
PT² = QS² + PR² [Since, RT ≅ QS]
PT² = 4² + 7²
PT² = 16 + 49
PT² = 65
Now for the length of PQ,
PQ² = QT² + PT²
PQ² = RS² + PT² [Since, QT ≅ RS]
PQ² = 4² + 65
PQ² = 16 + 65
PQ = √81
PQ = 9
Therefore, length of diagonal PQ is 9 units.
Option (B) will be the answer.

A fundraiser is being held to support a local nonprofit organization. Admission costs $10, and each raffle ticket costs $3. There are no other possible costs. If an event-goer pays the admission fee and buys x number of tickets, what type of function should be used to model the total amount spent by the event-goer at the event?
Answer:
y= 10+ 3x
10 is the admission fee
3x is the cost for each ticket
y is the total
The function for the total cost (y) spent by the event-goer at the event is
y = 3x+10
What is a function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Given that, Admission costs $10, and each raffle ticket costs $3. There are no other possible costs.
Let the total cost be y,
Therefore, establishing the function, for x number of tickets.
y = 3x+10
Hence, the required function is y = 3x+10
