That will be 5000
1km = 1000m sorta like m and cm
5×1000=5000
Answer:
AECG
Step-by-step explanation:
1
sqrt(49) = 7
sqrt(a^2) = a
sqrt(b^2) = b
For every two variables you can take one out from under the root sign and thorough the other one away.
Answer: E
2
sqrt(36) = 6
sqrt(a^2) = a See comment for 1.
b must be left where it is. There is only 1 of them.
6asqrt(b)
Answer: A
3. sqrt(25) = 5
sqrt(b^2) = b
a must be left alone. There's only 1 of them.
5b sqrt(a)
answer: C
4
sqrt(81 a b)
sqrt(81) = 9
The variables must be left alone. There's only1 of them
9 sqrt(ab)
Answer G
Answer:
Yes
Step-by-step explanation:
If you multiple 1/3 by 3/3 you would get 3/18
Answer:
An even function is:
f(x) = 7
Step-by-step explanation:
An even function accomplish the following condition:
f(x)=f(-x) (1)
Applying (1), we have:
- f(x)= (x-1)^2
f(-x)
(-x-1)^2 - f(x)= 8x
f(-x)
-8x - f(x)= x^2 -x
f(-x)
(-x)^2 +x
The last one is even.
