Answer: Choice C) 0.000042

$4.2 \times 10^{-5} = 0.000042$

There are four zeros between the decimal point and the 4.

==========================================

Explanation:

The exponent -5 means we move the decimal point five spaces to the left to go from 4.2 to 0.000042

If the exponent was positive 5, then we would move the decimal point five spaces to the right.

Elsie would like to take snowboarding lessons at powder mountain. She has saved $550 for lessons and a junior season pass that c

vlabodo [156]

So, she has 550 dollars saved. If the junior season pass costs 315, you subtract that from 550. You should then have 235 dollars. Next, you divide 235 by 45 dollars per lesson, and you should get 5.22. You can't buy half a lesson, so she only has enough for 5 lessons.

In which quadrant is the number –14 – 5i located on the complex plane?

loris [4]

Answer:

The complex number $r = -14 - i\,5$ belongs to the third quadrant of the complex plane.

Step-by-step explanation:

Let be $r = -14 - i\,5$ . In the complex plane, if $\Re (r) < 0$ (real component) and $\Im (r) < 0$ (imaginary component), the number belongs to the third quadrant of the complex plane. The complex number $r = -14 - i\,5$ belongs to the third quadrant of the complex plane.
