We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.
C.
don’t actually put that
39.58 and this is because the radius is half of the diameter so the diameter can be though of as 2r. The formula is C= 2pi r
5(x-5)^4(x+4)
you raise x-5 to the 4th power because 5 has a multiplicity of 4
3(3x - 2)
Distribute (multiply) 2 inside the parentheses.
3 * 3x and 3 * -2
9x - 6
