B & F Are The Only Two Points I Believe
Answer:
see the procedure
Step-by-step explanation:
we have
![12\ \frac{m}{s}](https://tex.z-dn.net/?f=12%5C%20%5Cfrac%7Bm%7D%7Bs%7D)
Remember that
![1\ km=1,000\ m](https://tex.z-dn.net/?f=1%5C%20km%3D1%2C000%5C%20m)
To convert m to km multiply by (1/1,000)
![1\ min=60\ sec](https://tex.z-dn.net/?f=1%5C%20min%3D60%5C%20sec)
To convert sec to min multiply by (1/60)
substitute
![12\ (\frac{(1/1,000)}{(1/60)})=12(\frac{60}{1,000})=0.72\ \frac{km}{min}](https://tex.z-dn.net/?f=12%5C%20%28%5Cfrac%7B%281%2F1%2C000%29%7D%7B%281%2F60%29%7D%29%3D12%28%5Cfrac%7B60%7D%7B1%2C000%7D%29%3D0.72%5C%20%5Cfrac%7Bkm%7D%7Bmin%7D)
These are the two equation
10-2
13-5
Answer:
x = log 10/log 3
Step-by-step explanation:
3^x - 4 = 6
3^x = 10
We take log base 3 of both sides since log_3 3^x is simply x.
log_3 3^x = log_3 10
x = log_3 10
We have an answer for x, but it is a log base 3. We want log base 10.
Now we use the change of base formula.
log_b y = log y/log b
x = log 10/log 3
Ralph's height is y
Ben's height is x
Ben's height is 1/20 of Ralph's height. How tall is Ralph?
