Hello there,
Okay, well you have asked what quantities are equivalent to 250 meters well 250 meters would be...
- 25000 centimeters
- 0.25 kilometers
- 820.20 feet
Hope I helped,
Amna
The expression 4a^2c^2 - (a^2-b^2+c^2)^2 has to be factored.
4a^2c^2 - (a^2 - b^2 + c^2)^2
=> (2ac)^2 - (a^2 - b^2 + c^2)^2
=> (2ac - a^2 + b^2 - c^2)(2ac + a^2 - b^2 + c^2)
=> (b^2 - (a^2 - 2ac + c^2))((a^2 + 2ac + c^2) - b^2)
=> (b^2 - (a - c)^2)((a + c)^2 - b^2)
=> (b - a + c)(b + a - c)(a + b + c)(a - b + c)
<span>
The factorized form of 4a^2c^2 - (a^2-b^2+c^2)^2 is (b - a + c)(b + a - c)(a + b + c)(a - b + c)</span>
Using linear functions, it is found that the two planes will be at the same altitude in 7 minutes.
<h3>What is a linear function?
</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For the first plane:
- Initial altitude of 1000 meters, hence .
- Ascending t a rate of 400 meters per minute, hence .
Hence, the equation is:
For the second plane:
- Initial altitude of 5900 meters, hence .
- Descending t a rate of 300 meters per minute, hence .
Hence, the equation is:
They will be at the same altitude at the value of x for which:
Hence:
The two planes will be at the same altitude in 7 minutes.

<u>Answer</u>
See below
Step-by-step explanation:
The given line has equation
The slope intercept form is
The slope of this line is
The line perpendicular to this line has slope
If this line passes through (5,-4), the point-slope form is
The slope-intercept form is
The standard form is
