What is the explicit rule for the geometric sequence? 4.05, 1.35, 0.45, 0.15, ...

Mathematics

Lelu [443]3 years ago
5 0

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

4.05, 1.35, 0.45, 0.15, ...

Since it is a geometric sequence.

So, here, a = 4.05

r = \dfrac{a_2}{a_1}=\dfrac{1.35}{4.05}=0.33

So, we know the formula for nth term in geometric sequence.

a_n=ar^{n-1}\\\\a_n=4.05(0.3)^{n-1}

Hence, First option is correct.

Solve for 6y+12=3y-3
kherson [118]
6y + 12 = 3y - 3

Subtract 3y on both sides

3y + 12 = -3

Subtract 12 on both sides

3y = -15

Divide by 3 on both sides

y = -5

Apply the distributive property to factor out the greatest common factor. 35+50=35+50=?
a_sh-v [17]

Answer with explanation:

The given mathematical expression to solve : 35+50

The prime factorization of each term can be written as follows :-

35=5\times7

50=5\times5\times2

We can see that the greatest common factor of both the terms = 5

So we rewrite the given expression as :-

5\times7+5\times10

By using distributive property :-

ab+ac=a(b+c) , we have

=5(7+10)=5(17)=85

A discount store bought two dozen cameras for $14 each.
____ [38]

Answer:

72.24

Step-by-step explanation:

Price for each camera = 14

Number of camera = 2dozen = 12 x 2 = 24

Total cp = 24 x 14 = 336

~~~~~~~~~~~~~~

Price for each camera=  10.99

Number of cams = 24

Total sp = 10.99 x 24 = 263.76

Loss = 336 - 263.76  = 72.24
