Answer:the answer is the first
Step-by-step explanation:
Because the expression can be written as -10r2/2r2+4+5r/2r2+4+3/2r2+4
Answer:
60cm
Step-by-step explanation:
perimeter of a square=4L
192cm=4L
L=48cm
Dilated by ratio 0.25
1 : 0.25 = 48 : 12
New length = 48+12 = 60cm.
Answer:
An explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Step-by-step explanation:
Given the geometric sequence

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

Determining the common ratios of all the adjacent terms

As the ratio is the same, so
r = 4
Given that f₁ = -1/2
substituting r = 4, and f₁ = -1/2 in the nth term


Thus, an explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Answer: 60
30
Step-by-step explanation: that’s the first two, good luck!
1/4= 4/16
4/16 is 1/4 simplified.
So, 4 beads are purple.
