You know the tangent point, so all you need for the tangent line equation is the slope. That is given by the derivative at x=3.
The derivative is
y' = 3x^2 -2
At x=3, this is y' = 3(3²) -2 = 25
Then your line in point-slope form is
y -22 = 25(x -3)
Answer:
x>3/2
Step-by-step explanation:
3 + 5 - 7 = 1
1, Hope this helps!
Answer:
x = 6
Step-by-step explanation:
2/(x-2) = 5/(4+x) - set up the ratios of similar sides
2(4 + x) = 5(x - 2) - cross multiply to solve
8 + 2x = 5x - 10 - simplify
18 = 3x - simplify to get x on one side of the equation
6 = x - divide both sides of the equation by 3 to isolate x
Answer:
Option (3)
Step-by-step explanation:
Given expression is,
(6 × 10⁸) ÷ (1.5 × 10⁻⁴)
We can rewrite the given expression as,
Now by solving this expression further,
[Since ]
=
=
Therefore, Quotient of the given expression is .
Option (3) will be the answer.
