(9x-2) - (5x+6) =
4x-8 , this is your profit function
part A)
we know that for every 1000 ft the temperature drops by 1.3.
so after 1000ft up it went down by 1.3(1)
2000ft up it went down by 1.3(2) or 2.6
3000ft up it went down by 1.3(3) or 3.9
after 10000 up it went down by 1.3(10) or 13.
part B)
well, the current temperature on the ground where the plane is sitting is -2.8°F, after 10000ft it dropped by 13°, so the temperature will just be -2.8 - 13 = -15.8°F.
The length of the hypotenuse will be equal to H=122.25 when value of x=14.
<h3>What is pythagorean theorem?</h3>
Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.
It is given that:
Value of x=14
The perpendicular is =6x+5=6x14+5=89
The base is =6x=84
So by using the Pythagorean theorem:-

Hence the value of hypotenuse will be H=122.25

Answer: 3
Step-by-step explanation:
Set them equal because they are the same so 15x+5=16x+2 so x+2=5 so x=3
<h2>
Answer</h2>
The answer to this question is 0.9
<h2>
Explanation</h2>
We know that
sequre of 9 is equal to 81 as 
Then sequre of 0.9 will be

So,
b = 
b = 
Exponent and square root cancel out each other
So, the answer is 0.9.
