Answer:
Step-by-step explanation:
The magnitude of 3D vector 
can be given by the following:
Plugging in given values, we have:
.
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:
29.187
Step-by-step explanation:
Cos38°= base/hypotenuse
Cos38°= 23/w
w= 23/Cos38°
w= 23/0.788
w= 29.187
Hope it helps :-)
Answer:
of fabric.
Step-by-step explanation:
-The amount of fabric needed is equivalent to the area of the two gardens.
-We calculate the combined areas as:
Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
Answer:
5x-3
Step-by-step explanation:
(3x + 5) + (2x - 8)
3x+5+2x-8
Bringing the like terms together,
3x+2x+5-8
5x-3
