    How far from the base of the house do you need to place a 10-foot ladder so that it exactly reaches the top of a 8-foot tall wall? (Use Pythagorean Theorem.)

    Explanation
    To find the distance from the base of the house to place the ladder, we can use the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the ladder acts as the hypotenuse, the height of the wall is one of the sides, and the distance from the base of the house to the ladder is the other side. By substituting the given values into the theorem, we can solve for the unknown distance. In this case, the correct answer is 6 feet or 6 ft.

  • 6. 

    A soccer field is a rectangle 60 meters wide and 80 meters long. The coach asks players to run from one corner to the corner diagonally across. What is this distance? (Use Pythagorean Theorem.)

    Explanation
    The distance from one corner to the corner diagonally across the soccer field can be found using the Pythagorean Theorem. According to the theorem, the square of the length of the hypotenuse (the diagonal distance) is equal to the sum of the squares of the other two sides. In this case, the two sides are the width (60 meters) and the length (80 meters) of the field. Therefore, the diagonal distance is equal to the square root of (60^2 + 80^2), which is approximately 100 meters.

  • 7. 

    The bottom of a ladder must be placed 3 feet from a wall. The ladder is 14 feet long. How far above the ground does the ladder touch the wall?  (Solve using the Pythagorean Theorem.)  Round answer to 2 decimal places.

    Explanation
    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 wall. The ladder is the hypotenuse, and its length is given as 14 feet. The distance from the bottom of the ladder to the wall is 3 feet. To find the height at which the ladder touches the wall, we can use the Pythagorean Theorem: (3^2 + h^2) = 14^2. Solving this equation gives h ≈ 13.67 feet. Therefore, the ladder touches the wall at a height of approximately 13.67 feet.

    Find the distance between the two points (-3, -2) and (3, -10).

    Explanation
    The distance between two points can be found using the distance formula, which is derived from the Pythagorean theorem. In this case, the x-coordinates of the two points are -3 and 3, and the y-coordinates are -2 and -10. Plugging these values into the distance formula, we get sqrt((3-(-3))^2 + (-10-(-2))^2) = sqrt(6^2 + (-8)^2) = sqrt(36 + 64) = sqrt(100) = 10. Therefore, the distance between the two points is 10.

    Rate this question:

  • 9. 

    Find the distance between the two points (3, 0) and (15, -5).

    Explanation
    The distance between two points can be found using the distance formula, which is derived from the Pythagorean theorem. The formula is: distance = sqrt((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the coordinates of the two points. Plugging in the coordinates (3, 0) and (15, -5) into the formula, we get: distance = sqrt((15 - 3)^2 + (-5 - 0)^2) = sqrt(12^2 + (-5)^2) = sqrt(144 + 25) = sqrt(169) = 13. Therefore, the distance between the two points is 13.

  • 10. 

    Find the distance between the two points (1, -1) and (5, 2).

    Explanation
    The distance between two points in a coordinate plane can be found using the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2). In this case, the x-coordinates are 1 and 5, and the y-coordinates are -1 and 2. Plugging these values into the formula, we get d = sqrt((5 - 1)^2 + (2 - (-1))^2) = sqrt(16 + 9) = sqrt(25) = 5. Therefore, the distance between the two points is 5.

    Rate this question:

  • 11. 

    Find the distance between the two points (14, -7) and (24, 3). Round answer to 2 decimal places.

    Explanation
    The distance between two points can be found using the distance formula, which is derived from the Pythagorean theorem. The formula is:

    distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

    In this case, the coordinates of the two points are (14, -7) and (24, 3). Plugging these values into the formula, we get:

    distance = sqrt((24 - 14)^2 + (3 - (-7))^2)
    = sqrt(10^2 + 10^2)
    = sqrt(100 + 100)
    = sqrt(200)
    ≈ 14.14

    Therefore, the distance between the two points is approximately 14.14.

    Find the distance between the two points (1, 8) and (7, 3).  Round answer to 2 decimal places.

    Explanation
    To find the distance between two points, we can use the distance formula: √((x2-x1)^2 + (y2-y1)^2). In this case, the coordinates of the two points are (1, 8) and (7, 3). Plugging in these values into the formula, we get √((7-1)^2 + (3-8)^2) = √(36 + 25) = √61. Rounding this to 2 decimal places gives us 7.81, which is the correct answer.

     The formula a2 + b2 = c2 works for all ______________ triangles.

    Explanation
    The formula a2 + b2 = c2, also known as the Pythagorean theorem, applies to right triangles. In a right triangle, one angle measures 90 degrees, and the square of the lengths of the two shorter sides (a and b) is equal to the square of the length of the longest side (c). This relationship holds true for all right triangles, regardless of their size or proportions.

    Rate this question:

  • 14. 

    The _______________________ Theorem states that a2 + b2 = c2.

    Explanation
    The Pythagorean Theorem is a mathematical principle that relates to right triangles. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery. The formula a2 + b2 = c2 represents this relationship, where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse.

    Rate this question:

  • 15. 

    In the Pythagorean Theorem, c is the ______________ of the triangle.

    Explanation
    In the Pythagorean Theorem, the letter "c" represents the length of the hypotenuse of a right triangle. The hypotenuse is the side opposite the right angle and is the longest side of the triangle. The theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Therefore, "c" is the correct answer as it represents the hypotenuse in the Pythagorean Theorem.

    Rate this question:

  • 16. 

    In the Pythagorean Theorem, a and b are the ______________ of the triangle.

    Explanation
    The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs. In this context, "a" and "b" refer to the lengths of the legs of the triangle. Therefore, the correct answer is "legs, leg".

    Rate this question:

  • 17. 

    To find how far apart two points are, you can use the _______________ formula.

    Explanation
    The distance formula is used to find the distance between two points in a coordinate plane. It involves finding the square root of the sum of the squared differences between the x-coordinates and the y-coordinates of the two points. By using this formula, you can accurately determine the distance between any two points in a coordinate plane.
