A drawbridge will sometimes open up to let boats and other water traffic pass
through. As it opens, the surface of the drawbridge raises above the level of
the roadway, as modeled by the function:
h+2
If the length of the drawbridge, r, is 25 meters, and the point Pis 16 meters
above the roadway, what is the distance d?
ANSWER IS 19.2
Answers
Answer:19.2
Step-by-step explanation:
The distance d is 19.2 meters.
What is Pythagoras theorem?The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The model forms a right angle triangle with the model given as
r = [tex]\sqrt{h^{2} -d^{2} }[/tex]
From the question we were asked to find d when r = 25 meters and the
h = 16 meters.
Make d the subject of the formula
r = [tex]\sqrt{h^{2} -d^{2} }[/tex]
square both sides
r² = h² + d²
d² = r² - h²
where
r = 25 m
h = 16 m
d² = r² - h²
d² = 25² - 16²
d² = 625 - 256
d² = 369
square root both sides
d = [tex]\sqrt{369}[/tex]
d = 19.2 meters
Hence, the distance d is 19.2 meters.

678.24 cm²
1,356.48 cm²
452.16 cm²
Answers
Answer:
452.16
Step-by-step explanation:
i got it right on test
The surface area of the cylinder is,
⇒ TSA = 452.16 cm²
We have to given that;
Height of cylinder = 6 cm
And, Diameter of cylinder = 12 cm
Hence, We get;
⇒ Radius of cylinder = 12 / 2 = 6 cm
We know that;
The formula for the total surface area of a given cylinder whose radius is r and height is h is,
TSA = 2πr (h + r)
Hence, We get;
TSA = 2πr (h + r)
TSA = 2 × 3.14 × 6 (6 + 6)
TSA = 37.68 × 12
TSA = 452.16 cm²
Thus, The surface area of the cylinder is,
⇒ TSA = 452.16 cm²

A rectangle lengths 12m and 17m and is dilated using the dilation (x, y) -> ( 0.4 x, 0.4y). What is the perimeter of the dilated rectangle?
Answers
Answer:
Perimeter of the dilated rectangle = 23.2 m
Step-by-step explanation:
If a point is dilated by a scale factor = k
Coordinates of the image point after dilation will follow the rule,
(x, y) → (kx, ky)
From the given rule,
(x, y) → (0.4x, 0.4y)
Which reveals that the figure has been dilated by a scale factor = 0.4
Length of the rectangle = 12 m
Width of the rectangle = 17 m
If the given rectangle is dilated by a scale factor of 0.4,
Length of the image rectangle = 12 × 0.4 = 4.8 m
Width of the image rectangle = 17 × 0.4 = 6.8 m
Perimeter of a rectangle = 2(length + width)
Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)
= 23.2 m
