Answer:
Step-by-step explanation: Sub -3 into where all the u’s are. So it would be
(-3)^2 - 2(-3) + 4
Which would equal 19
Assuming that the units of speed are also in minutes, for instance km/min or m/minute. Then you would not need to convert time into another unit. As for multiplying the bases of 10, remember that 10 = 10^1. So it would be 10^8+1 = 10^9. So the result would be 24 • 10^9 but in proper scientific notation it would be 2.4 • 10^10.
Yet, I believe you are working with the speed of light and thus you would need to convert 8 minutes into seconds which would be 8 • 60 = 480 seconds. Then do the following operation:
480 = 4.80 X 10^2
(4.80 X 10^2 seconds)(3.00 X 10^8 metres/second)
Simply multiply the whole numbers, and the bases of 10, and put in proper scientific notation.
Answer:
B i think
Step-by-step explanation:
The product of 1 and any number is the number (hence why it is most likely b). But instead of it being 4, it would be -4 because multiplying a negative by a positive results in a negative.
