Answer:
1.330×10¹³
Step-by-step explanation:
d=m/v
m=dv
m=(3.12×10⁻²)(4.266×10¹⁴)
m=1.330×10¹³
To solve this question, we need to get x by itself. We can do that by subtracting 3.6 from each side. But, adding a negative is the same thing as subtracting a positive number. That means that you could also add -3.6 to both sides.
well, we know the common difference is -3, to go from the 4th term to the 8th term, we need to add "d" 4 times or namely 3+4(-3), likewise to go from the 13th term to the 19th term we have to add "d" 6 times, or namely -24 + 6(-3).
This is known as Einstein's proof, not because he was the first to come up with it, but because he came up with it as a 15 year old boy.
Here the problem is justification step 2. The written equation
BC ÷ DC = BC ÷ AC
is incorrect, and wouldn't get us our statement 2, which is correct.
For similar triangles we have to carefully pair the corresponding parts to get our ratios right:
ABC ~ BDC means AB:BD = BC:DC = AC:BC so BC/DC=AC/BC.
Justification 2 has the final division upside down.
