Answer:
The require gradient is 3/5
Step-by-step explanation:
y(x) = 5x/(2x^2+4).................(1)
y(sqrt(3)) = sqrt(3)/2 => (sqrt(3), sqrt(3)/2) is a point on the curve of (1)
differentiate y(x) with respect to x using the quotient rule to get
y'(x) = 20x^2/(2x^2+4)^2 ................(2)
substitute x = (sqrt(3), sqrt(3)/2) in (2)
y'(sqrt(3))
= 20(sqrt(3))^2 / (2(sqrt(3))^2 + 4)^2
= 20*3 / (10)^2
= 60 / 100
= 3/5
Answer:
-1/7
Step-by-step explanation:
The first step is to isolate the variable, x. To do so, add x to both sides. This gives you the new equation: 2 + 7x = 1.
Now, subtract 2 from both sides to further isolate the variable, giving you 7x = -1.
Divide both sides by 7, giving you the final equation of x = -1/7.
