From the congruent alternate interior angles resulting from the parallel lines, we have the equation $8x-34=5x+2.$ Solving, we have $x=12^\circ$ and $\angle D E F =5x+2=\boxed{62^\circ}.$

How do you rearrange the formula for the variable indicated:

PSYCHO15rus [73]

Watch closely. I'll try to go slow:

You said <u>v² = 2 g t</u>

Divide each side by 2g : <em>v² / 2g = t</em>

Did you follow that ?

A method for determining whether a critical point is a minimum. True or false?

natita [175]

Answer:

We can find if a critical point is a local minimum or maximum by looking at the second derivatives.

Step-by-step explanation:

If you take the first derivative, you will find the slope at the given point, which if it is a minimum or a maximum will be 0.

Then we take the second derivative. If that number is a positive number, then we have a local minimum. If it is a negative number, then it is a local maximum.
