Answer:

  1.  c) 62.5 mA
  2.  c) 9 seconds

Step-by-step explanation:

1. resistance is multiplied by 20/5 = 4, so current is multiplied by 1/4.

  (1/4)(250 mA) = 62.5 mA . . . . matches choice C

__

2. distance is multiplied by 144/16 = 9, so time is multiplied by √9 = 3. The time it takes to fall 9 times as far is ...

Answer:

  cos(θ) = (5√74)/74

Step-by-step explanation:

The length of the hypotenuse is given by the Pythagorean theorem:

  h = √(5² +7²) = √74

The cosine of the angle is the ratio of the adjacent leg to the hypotenuse:

  cos(θ) = 5/√74 = (5√74)/74

How to write fractions in simplest form?<br> ( I give brainliest )
diamong [38]

It's pretty easy, take the example of this fraction... \frac{2}{4}

What you do in here is that you note down the <em>factors</em> of 2 and 4 over here.

<u><em>Factors of 2 and 4:</em></u>

2 = 1, 2

4 = 1, 2, 4

Now, you see that the <em>GREATEST</em> Common Factor (GCF) over here is 2.

Now that we see the GCF of 2 and 4 is 2, what you do next is, you have to <u>divide 2 by 2 AND 4</u><u><em>. </em></u>When you do this, you will get your results. 2 = 1 and 4 = 2, now put this in the fraction form again, meaning switch 2 with 1, and 4 with 2 in the fractions... \frac{1}{2}

So your simplified fraction is \frac{1}2}!
