Answer:
Not geometric
Step-by-step explanation:
In a geometric sequence, each term is multiplied by a common ratio to get the next term.
So if this is a geometric sequence, then dividing each term by the one before it should result in the same common ratio.
42 / 21 = 2
126 / 42 = 3
504 / 126 = 4
The ratios are different. This is not a geometric sequence.
Answer:
B
Step-by-step explanation:
The right side is 2x larger than the left side of diagram B. So you can safely assume the right side is 10 and the left is 5.
Answer:
1.y=3x+1
2.y=1/3x+2
3.y=-2x+5
4.y=4x
5.y=4x-4
6.y=-2x-5
Step-by-step explanation:
(i)
y=mx+c
10=(m)3+1
10=3m+1
10-1=3m
m =3
y=3x+1
And so on...
95° because the angle is mirrored with the other side
For this questions you need to memorize formula of triangle area. for question 5, just substitute the value into the formula. for Q6 you need to use pythagorean theorem formula to find the lenght of each triangle that i already seperated
