Her first rate was faster. The 10 minutes with a change in elevation of -200ft.
In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the -200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone -400ft in 20 minutes while the second rate was only -300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.
Answer:
Two congruent figures
Step-by-step explanation:
Here we have to use the definition of congruent.
Congruent means equal to each other.
Example.
If the two triangles said be congruent, their corresponding angles and corresponding sides are equal.
They will have to same size of the sides and same measure of angles.
Two equal polygons, that is two congruent figures.
Hope this will help you.
Thank you.
|a+bi| = √(a² + b²)
-4-√2 i -> take a = -4 and b = -√2
|-4-√2 i| = √[ (-4)² + (<span>-√2)² ]
= </span><span>√[ 16 + 2<span> ]
</span></span><span>= √[ 18 ]</span> = <span>√[ 9 * 2 ]
= 3√2
the absolute value is 3√2</span>
