We need to cancel out the discontinuity in x = 4
In order to do that, factorize the numerator:
5x⁴ - 20x³ = 5x³(x-4)
This way, your function will be:
f(x) = <span>5x³(x-4) / (x-4)
and the two parentheses cancel out, leaving
</span>f(x) = <span>5x³
</span>
which at x = 4 gives:
f(4) = <span>5·4³</span> = 5 · 64 = 320
Therefore K = 320.
Well its definitely not c i think not 100 percent might want to see another answer but my answer would be D.58
Answer:
136.34 m to the nearest hundredth.
Step-by-step explanation:
The runners paths and the distance between them after 30 second form a triangle.
The side opposite the 85 degree angle is 180 m and one of the other sides is 130 m.
We need to find the third side.
We can use the Cosine Rule to do this:
If the third side is x m then:
180^2 = 130^2 + x^2 - 2*130x cos 85
180^2 = 130^2 + x^2 - 260 * x * 0.08716
180^2 = 130^2 + x^2 - 22.6616 x
x^2 - 22.6616 x - 15500 = 0
x = [22.6616 +/- sqrt ((-22.6616)^2 - 4 * -15500) ] / 2
x= 136.34 m.
