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
1: 0.5 and 50%
2: .2 and 20%
3: .75 and 75%
10: (1/10) and 10%
11: (3/5) and 60%
12: (1/4) and 25%
Yes because if you multiply 0.6 by 10, it would equal 6. So yes, the 6 in 26.495 IS 10 times the value of the 6 in 17.64.
Answer:
see the explanation
Step-by-step explanation:
Observing the picture
1) For y=-1
The answer is undefined (there is no corresponding value for x)
2) For y=0
we have the points (-3,0) and (6,0)
therefore
x=-3, x=6
3) For y=2
we have the points
(-2.25,2)
(0.75,2)
(4,2)
therefore
x=-2.25, x=0.75, x=4
3) For y=3
we have the points belong to the interval [-2,0]
so
Answer:
132°
Step-by-step explanation:
because the lines are parallel x + 48° must be 180°
therefore x = 132°
