Answer:
B) y=10
Step-by-step explanation:
10+10=20
20*2/5=8
The angle of depression is 29.0521°. So it is a safe landing.
Step-by-step explanation:
Step 1:
The plane is flying at a height of 25,000 feet and 45,000 feet away from the landing strip. Assume it lands with an angle of depression of x°.
So a right-angled triangle can be formed using these measurements. The triangle's opposite side measures 25,000 feet while the adjacent side measures 45,000 feet. The angle of the triangle is x°.
To determine the value of x, we calculate the tan of the given triangle.

Step 2:
The length of the opposite side = 25,000 feet.
The length of the adjacent side = 45,000 feet.

So x = 29.0521°. Since x < 30°, it is a safe landing.
The rate of change is meaning the slope. The slope of A is 8, therefore, the answer would be 7.
hope this helps :)
4.5 boxes of nails are required for finishing 2 tables
Step-by-step explanation:
Given:
3.4 boxes of nails are required for finishing 1.5 tables
Required:
How much boxes of nails would he use for finishing 2 tables
Solution:
We can solve using Unitary Method:
Nails needed to finish 1.5 tables = 3.4 boxes
Nails needed to finish 1 table = 
Nails needed to finish 2 tables = 
So, 4.5 boxes of nails are required for finishing 2 tables.
