Answer: $f'(1)=\dfrac{4}{2y+1}$

Step-by-step explanation:

To find the tangent, you need to find the derivative with respect to x.

Then substitute x = 1 into the derivative.

Given: 0 = 2x² - xy - y²

Derivative: 0 = 4x - y' - 2yy'

Solve for y': 2yy' + y' = 4x

y'(2y + 1) = 4x

$y'=\dfrac{4x}{2y+1}$

$\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}$

Convert 80 km per hour and 120 km per hour to meters per second

$\large \bold {ANSWER}$

$\large \boxed { \large \sf \green{ 80 km/h = 22.22 m/s }}$
$\large \boxed { \large \sf \green{ 120 km/h = 33.33 m/s }}$

$\large \bold {SOLUTION}$

The first thing we must do is convert kilometers to meters. We will do this by multiplying by 1,000, since 1 km corresponds to 1,000 meters.

80*1000 = 80,000
120*1000 = 120,000

Now that we've done that, let's divide the values by 3,600, because an hour is 60 minutes, and each minute is 60 seconds, so 60*60 is 3,600.

$\frac{80.0\not0\not0}{3.6\not0\not0}=22.22$
