Answer=4000ft
There are 3280.84 feet in 1 kilometer
1km=3280.84ft
4000ft >3280.84 ft
therefore, 4000ft is longer than 1 km
4000ft>1km
Answer:c
Step-by-step explanation:
Answer:
Positive
Step-by-step explanation:
A line with a positive slope is one that as the x-value increases, the y-value increases as well.
As we go from left to right on this graph (the x-value increasing) the y-value of the graph increases. This means it has a positive slope.
Answer:
See explanation.
(Before continuing reading, I took the base to be 3. Please tell me if you didn't want the base to be 3.)
Step-by-step explanation:
I assume 3 is suppose to be the base. Let's list some values that can be written as 3 to some integer.
3^0=1
3^1=3
3^2=9
3^3=27
3^4=81
3^5=243
......
I could have also did negative integer powers, but this is all I really need to convince you that log_3(28) is between 3 and 4.
log_3(28) means the value x such that 3^x=28.
Since 28 is between 27 and 81 in my list above, that means 3^x is between 3^3 and 3^4. This means that x is a value between 3 and 4.
