The first and last one are true!
Answer:
43,000: 4.3×10^4
0.0072: 7.2×10^-3
0.0000901: 9.01×10^-5
Step-by-step explanation:
scientific notation: a×10^b, where should be 0<a<10
Step 1. Count the zeros
Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit
------------------------
43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)
0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)
0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)
Hope this helps!! :)

Answer:
year 2000: P = 50
year 2004: P = 24
Step-by-step explanation:
t is the number of years since 2000, so for the year 2000, we have that t = 0.
Using this value in the equation, we find that:
P = -6 * 0 + 50 = 50
The price of the stock in year 2000 is 50.
For the year 2004, we have that t = 4, so using this value in the equation for P, we have:
P = -6 * 4 + 50 = -24 + 50 = 26
The price of the stock in year 2004 is 24.
n^2>18
n^2 is n squared, > is the greater than symbol
