Point D'' (-4,-2) is a vertex of a quadrilateral A'' B'' C'' D''. The original image was rotated 270 degress counterclockwise around the origin and then reflected over the x-axis.

Part A: What are the coordinates of the original image's point D before the composition of transformations?

A. (-4,-2)
B. (-2,-4)
C. (-2,4)
D. (2,-4)

Part B: The original image is quadrilateral ABCD. Point C is on the same y-axis of point D, but five units to the right of point D. If quadrilateral A'' B'' C'' D'' is transformed following the rule (x,y)---> (x-4, y+2), what are the coordinates of point C''?

Step-by-step explanation:

part A: D'' (-4 , -2)  (reverse) reflection over x axis -> (-4 , 2)

           (-4 , 2) rotated 270 degrees clockwise: -> D (-2 , -4)

Part B: C (-2+5 , -4) = (3 , -4)

Submarines use sonar systems, which are similar to radar systems, to detect obstacles. Sonar systems use sound to detect objects underwater.



a. You are traveling underwater in a submarine. The sonar system detects an iceberg 4000 meters ahead, with an angle of depression of 34∘ to the bottom of the iceberg. How many meters must the submarine lower to pass under the iceberg?



The submarine must lower at least ____ meters.


Question 2
b. The sonar system then detects a sunken ship 1500 meters ahead, with an angle of elevation of 19∘ to the highest part of the sunken ship. How many meters must the submarine rise to pass over the sunken ship?

The submarine must rise at least ____ meters.

Answers

Answer:

a. tan(34)= O/4000 and follow the solving to get the distance it must be lowered

b. (Same idea as a) tan(19)=1500/A and solve to get the distance

The submarine must lower at least 2698 meters and the submarine must rise at least 516.45 meters.

Given that, the sonar system detects an iceberg 4000 meters ahead, with an angle of depression of 34∘ to the bottom of the iceberg.

What are trigonometric angles?

Trigonometric angles are the angles in a right-angled triangle using which different trigonometric functions can be represented. Some standard angles used in trigonometry are 0º, 30º, 45º, 60º, 90º.

a) We know that, tan θ = (Perpendicular/Base)

Let the number of meters must the submarine lower to pass under the iceberg be x.

tan θ = x/4000

⇒ tan 34° = x/4000

⇒ 0.6745 = x/4000

⇒ x = 0.6745 × 4000

⇒ x = 2698 meters

b) Let the number of meters must the submarine rise to pass over the sunken ship be y.

tan θ = y/1500

⇒ tan 19° = y/1500

⇒ 0.3443 = y/1500

⇒ y = 0.3443 × 1500

⇒ y = 516.45 meters

Therefore, the submarine must lower at least 2698 meters and the submarine must rise at least 516.45 meters.

Which proportion can be used to find the arc length, s, in units?

Answers

Answer:

Option B

Step-by-step explanation:

Formula to be used to calculate the length of an arc,

Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = Angle subtended at the center by the arc

r = radius of the circle

By substituting values in the formula,

s = [tex]\frac{150}{360}(2\pi )(42)[/tex]

[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]

[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]

Therefore, Option B will be the answer.

X=17.


Hope this helps

Answer:

See below, please!

Step-by-step explanation:

Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.
