Answer:

and x=4
Step-by-step explanation:
We are given that a curve

We have to find the equation of tangent at point (4,2) on the given curve.
Let y=f(x)
Differentiate w.r.t x

By using the formula 
Substitute x=4
Slope of tangent

In given question


By comparing we get a=4
Point-slope form

Using the formula
The equation of tangent at point (4,2)




answer: x=6
Step-by-step explanation:
move all terms that don't contain x to the right side and solve.
7.0717 million
Lets see:
1 million = 1.000.000
So, 7.0717 million = 7.071.700
7.071.700 can be read as "seven million seventy one thousand and seven hunred"
If you wanna split it you can split in
seven million = 7 million
seventy one thousand = 71 thousand
seven hundred = 7 hundred
