Answer:
kjhg
Step-by-step explanation:
The answer is 1. This is because 5 is a prime number, so the only factors are 1 and 5. 5 is not a factor of 2.
Instead of using the quotient rule, you can first expand <em>y</em> :
<em>y</em> = (4<em>x</em> - 1)^2 / <em>x</em> ^2 = (16<em>x</em> ^2 - 8<em>x</em> + 1) / <em>x</em> ^2 = 16 - 8/<em>x</em> + 1/<em>x</em> ^2
Then the derivative is
d<em>y</em>/d<em>x</em> = -8/<em>x</em> ^2 - 2/<em>x</em> ^3
The tangent to the curve at (-1, 25) then has a slope or gradient of
d<em>y</em>/d<em>x</em> = -8/(-1)^2 - 2/(-1)^3 = -6
Answer:
600kW
Step-by-step explanation:
Referring to the fact that 10m/s of wind is 500kW so divide 500 by 10.
500/10=50
So there is 50 kW is 1m/s of wind. Now multiply 12 by 50
12x50=600
So for 12m/s of wind there is 600kW
