The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of right angled triangle.
Let d represent the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:
Angle = 90 - 67 = 23°
Using trig ratio:
tan(23) = d/1143
d = 485.2 feet
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.

The given function is
f(x) = x⁵ ln(x)
Note that ln(x) is undefined as a real function for x ≤ 0.
Therefore the domain of the function is
0 < x <∞, or x = (0,∞).
Answer: x = (0, ∞) or 0 < x < ∞
Answering part A:
5x + -3x 7y + 3y + 2y 4xy doesn't have a like term
Step-by-step explanation:
like terms are when in an equation they might have variables that match like 4y + 7y they have the same variable which is y or 6 + 7 they don't have a variable at all but they are similar in that way. Btw why it says -3x is because I changed the equation to be all addition so I did kcc you don't have to do that if you find a different solution :) anyway lets move on to part b
Answering part B:
4xy + 2x −2y
Answer:
Step-by-step explanation:yes
Answer:
D: 4
Step-by-step explanation:
The degree of a vertex is the amount of connections it has to the point.
Vertex E has 4 connections so therefore the answer is D.
