When flying at an altitude of 5 miles, the lines of sight to the horizon looking north and south make about a 173.7 degree angle
oksian1 [2.3K]
5 miles high is one of the sides of a triangle depending on accuracy level
h^2=x^2+y^2
we don't have 2 distances
Tan A=O/a
O=a tan A
We solve for O because the angle is at the top of the line going up and we want the opposite angle that is along the ground
O=5×tan(173.7/2)=90.854033512
The distance he can see is:
90.85*2~181.7 miles

Now we need to find the distance between lines:
The north south distance between each line is 69 miles
thus the number of degrees he will see will be:
181.7/69
=2 19/30

An initial deposit of $7,000 earns 6.5% interest, compounded monthly. How
zavuch27 [327]

Answer:

$34,300

Step-by-step explanation:

First, we need to find how much interest is earned in one month : 7,000 * 6.5% = 455

455 is how much you gain monthly, multiply that by 12 to find the annual interest so 455 * 12 = 5,460

You then multiply that number by 5 to find the interest of the span of the 5 years

5,460 * 5 = 27,300

You add the original number to the interest with 27,300 + 7,000 = 34,300 in the account

1) If X = 2, calculate the value of: 2x squared - x
Marrrta [24]
Use PEMDAS
1. 2(2^2)-2
=2(4)-2
=8-2
=6

2. 2((-2)^2)-(-2)
=2(4)+2
=8+2
=10

The table shows the solution to the equation |2x - 4| - 3 = 3:
marissa [1.9K]
We are given the steps that are laid to determine the value of x in the expression |2x -4| - 3 =  3. First step is to add 3 to both sides, then simplify, then determine x. The first incorrect step is step 1 since we add not subtract.
