Answer:
4,022.5 m
Step-by-step explanation:
When an observer watches an object lying on the ground from an elevated point on the ground then the angle formed between horizontal line and the line of vision is known as ANGLE OF DEPRESSION.
When an observer watches an object from a point on the ground situated at some height from the ground from the ground then the angle formed between horizontal line and the line of vision is known as ANGLE OF ELEVATION .
Let the distance of the rock from the airplane be x meters.

The generic equation of the line is:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
Substituting values:
m = (20-15) / (10-5)
m = (5) / (5)
m = 1
We choose an ordered pair:
(xo, yo) = (5, 15)
Substituting values:
y-15 = 1 (x-5)
y = x - 5 + 15
y = x + 10
Answer:
An equation of the line that passes through the points (5 15) and (10 20) is:
y = x + 10
gf(x)=g(f(x))
f(x)=3x and g(x)=5x-3
gf(x)=g(f(x))=g(3x)=5(3x)-3=15x-3
Answer: Juan buys 2.47 pounds of cheese in all.
The question is asking you how many pounds of cheese he bought. He buys 1.09 pounds of cheddar cheese and 1.38 pounds of mozzarella cheese. All we need to do is add 1.09 and 1.38.
Step one: Set up the equation (make sure the decimals are lined up)
1.09
+1.38
Step two: Add
1.09 *<em>make sure to bring down the decimal </em>
+ 1.38
------
2.47
So all together Juan bought 2.47 pounds of cheese.
Answer:
The correct option is C). proportional; congruent; similar
Step-by-step explanation:
Theory :
If triangle is dilated from the origin at a scale factor of 2 to create Triangle then, image of triangle and original triangle are similar to each other
Also, for similar triangles, corresponding angles are equal or congruent and corresponding sides are in ratio or scaled
For example : Figure show that triangle ABC is dilated by factor of 3 and centered at (-5,-4)
Question say: The triangles' corresponding sides are ________, and their corresponding angles are ________; therefore, the triangles are ________.
Answer : The triangles' corresponding sides are <u>proportional</u> and their corresponding angles are <u>congruent </u>therefore, the triangles are <u>similar</u>
