Answer:
Step-by-step explanation:
If you want to find out how many times larger something is than something else, you have to divide. We will set up a problem that looks like this:
Diving 2.1 by 4.2 gives us .5; to divide the exponents, we remember that if we divide like bases we have to subtract the exponents. 10 is our base in both cases, so 8 - 2 gives us 6, resulting in:
However, this isn't in scientific notation. We need to move the decimal one more place to the right, which in trn reduces the exponent by 1:
Answer:
C. ![y=\sqrt[3]{-x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D%20-1)
Step-by-step explanation:
Consider the eparent function ![y=\sqrt[3]{x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7Bx%7D)
The graph of this function is shown in the attached diagram - red curve.
Reflect this graph across the y-axis, you'll get the blue line which equation is
![y=\sqrt[3]{-x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D)
Translate this graph 1 unit down, then you'll get green line (that is exactly the graph from your image) and the function for this line is
Answer:
0.75 kilograms
Step-by-step explanation:
All you need to do is move the decimal.
use 
to get 
then use 
and 
also, 
to get 
then again use the first identity In both pairs, i.e.
to get 
multiply and divide by 4 to get the RHS.
because, 
squaring both sides,
