Answer:

Step-by-step explanation:

Standard Form means to change it into a decimal that is not scientific notation.

The question you have given is

.0012

The way you think of it is the number of zeros is numerically 1 less than the power when the power is minus.

Write the decimal in expanded form using Powers of 10 with exponents. 562.816
Firdavs [7]

562.816 = 5×10² +6×10¹ +2×10⁰ +8×10⁻¹ +1×10⁻² +6×10⁻³

<em>Comment on this problem</em>

Understanding this representation of place value goes a long way toward understanding scientific notation. It also helps understanding of numbers written in bases other than 10.

Use inductive reasoning to determine the units digit of the number 3 to the 58 power
I am Lyosha [343]

We must find a pattern in the powers of 3:

3^0 = 1

3^1 = 3

3^2 = 9

3^3 = 27

3^4 = 81

So, as you can see, both 3^0 and 3^4 end with 1. So, we can generalize as follows:

3^{4k+0} \text{ ends with } 1

3^{4k+1} \text{ ends with } 3

3^{4k+2} \text{ ends with } 9

3^{4k+3} \text{ ends with } 7

Since 58 = 14\cdot 4 + 2, we can deduce that 3^{58} ends with 9.

Stan drove for h hours at a constant rate of r miles per hour. How many miles did he cover during the final 20 minutes of his dr
igor_vitrenko [27]

rDistance (D) = Speed (S) * Time (T)
S * T = r*20/60 mins = r / 3

So r/3

What is the minimum value of the graph of y=sin x assumes
Alex
Short answer: - 1
The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)

You will find no lower value that y = - 1 (nor any value greater than y = 1)
