Answer: 11378.58 ft
Step-by-step explanation:
1. Draw a figure like the one attached, where A is the position of the airplane and B and C are the positions of the cars.
2. The distance between the cars is the length BC, then, you need to calculate the measure of BD and DC to add them and obtain BC.
<h2> 3. You know the opposite side and the angles of depression, then, you can calculate the distance between the cars as following:</h2>
Answer:
96 degrees
Step-by-step explanation:
you have two angles that each measure 42 degrees, giving you 84 degrees combined
there are 180 degrees in a triangle, therefore the vertex angle is equal to 180 minus 84, or 96 degrees
check:
42 + 42 + 96 = 180
180 = 180
Answer:
1:3
Step-by-step explanation:
3/3=1
9/3=6
Slope intercept form
y = mx + b
-2x + 5y = 10
5y = 2x + 10
Divide by 5
y = 2/5x + 2
You are correct! The problems that can arise with a function domain are:
- Denominators that become zero
- Even-degree roots with negative input
- Logarithms with negative or zero input
In this case, you have a denominator, and you don't have roots nor logarithms. This means that your only concern must be the denominator, specifically, it cannot be zero.
And you simply have
So, the domain of this function includes every number except 3.
