Answer:
Step-by-step explanation:
Assumed the starting point is the sea level 0.
<u>After 2.8 min the diver is at position:</u>
- 20 1/2 * 2.8 =
- 20.5 * 2.8 =
- 57.4 feet below sea level
<u>The position change after next 2 minutes:</u>
<u>The position of the diver after 4.8 min:</u>
- 57.4 - 50 = 7.4 feet below sea level
Answer:
65 on ED 2020.
for The measure of AngleMKJ is 80°. After analyzing the diagram, Janelle concludes that Ray K L is an angle bisector.
Point K has three lines extending from it. One line extends to point M, another to point L, and another to point J. Angle M K L is (2 x + 10) degrees. Angle L K J is (3 x minus 5) degrees.
Which statement best describes Janelle's conclusion?
Her conclusion is incorrect because 2x + 10 is not equal to 3x – 5.
Her conclusion is incorrect because the angles are not marked; therefore, no conclusion can be drawn.
Her conclusion is correct because the value of x is 15.
Her conclusion is correct because
mAngleLKM + mAngleLKJ = mAngleMKJ.
Step-by-step explanation:
Answer: option D) translated (x,y) (x-2, y+2) and rotated 90 degrees counterclockwise about the origin.
Justification:
1) Translation (x,y) → (x - 2, y + 2) ⇒ (9, 1) → (9 - 2, 1 + 2) = (7, 3)
2) Rotation 90° counterclokwise ⇒ (x, y) → (-y, x) ⇒ (7, 3) → (-3, 7)
So, there you have the demonstration that the translation of J (9,1) according to (x,y) → (x - 2, y + 2), followed by a rotation of 90° counterclockwise produces the image J' (-3, 7).
