Answer: 3996 meters
Step-by-step explanation:
Given: Maya is camping at the top of mount armstrong at an elevation of 7832 meters.
Consider the pont of sea level be 0.
Then the height of the point where Mary is = +7832 meters (by using integers)
Juan is scuba diving 160 meters below sea level.
⇒The height of the point where Juan is =-160 meters
The distance between them =
The mid point of the distance=
Hence, Maya & Juan meet will meet at an elevation of 3996 meters .
Answer:
There are three diferent methods for solving linear equations. We get same answer by solving with any of them but each of them has its own advantages and disadvantages.
Step-by-step explanation:
The different methods for dolving the linear equations are:
- Substitution
- Elimination
- Graphing
The advantages and disavantages with examples are as follows:
A: Substitution- In this we write an equation for second variable when the first is given which gives an advantage. It is considered best when one or both the equation is solved for any one of the variable.
When we have one of the variable whoes coefficient is 1 it works well.
Example:
Let the equation be
x=
we can substitute this value in another equation,
Then in that case,
x=
=
⇒5y=35
⇒y=7.
Now, as we have value for one variable we will substitute it in the first equation given, we will get
x=3.
B: Elimination- It is the best method to use. it is used when both of the given equation are in standard form. It is also used when all the given variables have a coefficient other than 1.
C: Graphical representation- It is best used when a new student is trying to learn equation solving as it gives a visual idea of solving the linear equation. The disadvantages associated with it is that it takes more time than the other two methods and is also less exact. It should be recommended only when we get a question to be solved with a graph.
Answer:
l = 5.62 units
Step-by-step explanation:
The formula for measuring the length of an arc is expressed as;
r is the radius
is the central angle in radians
r = LM = 7units
Substitute into the formula
Hence the length of arc LN is 5.62 units to the nearest hundredth
