Answer:
When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal. In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,
3.00 x 10⁻⁴
Answer:
ill explain better
Step-by-step explanation:
use distrubrity property and you get 6x + 6x -18y+6+(-9) then you add 18 because you have to get the y way so you do the opposite of subtracting which is adding so when you add the 18 to it self you then add the 18 to one of the 6x the you get 24x+6x+-4 which u add 6 to -9 the to combine like terms and get 30x+-4
Answer:
h=2/3
Step-by-step explanation:
6h-1=3
add one to each side
6h=4
divide by 6
h=4/6
Simplify (divide by 2)
h=2/3
Answer:
The measure of the angle between the vectors = Ф = 11.30°
Step-by-step explanation:
Given

Next, find the lengths of the vectors:

u = ⟨2, –3⟩


u = ⟨2, –3⟩


Finally, the angle is given by:

cos (Ф) = 5/√26
Ф = arc cos (cos (Ф)) = arc cos (5 √26) / (26)
Ф = 11.30°
Thus, the measure of the angle between the vectors = Ф = 11.30°
Answer:
x=6
Step-by-step explanation:
Hello There!
Our whole objective is to isolate the variable (x) by using inverse operations
2x-3=9
to get rid of the -3 we add 3
Remember whatever we do to one side we have to do to the other side so we add 3 to each side
-3+3 cancels out
9+3=12
now we have
12=2x
now to get rid of the 2 we divide by 2
so we divide each side by 2
2x/2=x
12/2=6
we´re left with
x=6
