Given the geometric sequence where a1=1 and the common ratio is 6 what is the domain for n

Mathematics
1 answer:
stellarik [79]4 years ago

Answer:

Domain: n\ge1

Step-by-step explanation:

For a geometric sequence, the n-th term is given by:

a_n=a_1r^{n-1}

From the question, a_1=1 and r=6.

Hence the explicit formula for the sequence is:

a_n=6^{n-1}, where n\ge1

Therefore the domain is natural numbers or positive integers.

Write in scientific notation <br><br> (2.3x10^8)x(7.84x10^4)
Keith_Richards [23]

Answer: 1.8032 x 10^13

Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the ten. If your decimal is being moved to the right, then the exponent will become negative. If your decimal is being moved to the left, then the exponent will become positive.

I hope this helps you out!

Answer:

a) $160

b) $116.50

Step-by-step explanation:

a) Let the original price of the yellow bicycle be $x.

Since both has the same original price,

original price of yellow bicycle= 100% x

original price of green bicycle= 100% x

Discounted price of yellow bicycle

= (100% -25%) x

= 75% x

Discounted price of green bicycle

= (100% -30%) x

= 70% x

Difference in cost

= 75%x -70%x

= 5% x -----(1)

From 2nd paragraph:

Discounted price of yellow bicycle

= Kyreen's money +3.50

Discounted price of green bicycle

= Kyreen's money -4.50

Difference in cost

= (Kyreen's money +3.50) -(Kyreen's money -4.50)

= Kyreen's money +3.50 -Kyreen's money +4.50

= 3.50 +4.50

= 8.00 -----(2)

Equating (1) and (2) together:

5% x= 8.00

\frac{5}{100} x = 8

x = 8 \div  \frac{5}{100}

x = 8 \times  \frac{100}{5}

x= 8 ×20

x= 160

Thus, the original price of the yellow bicycle is $160.

_______

b) Amount Kyreen has at first

= discounted price of yellow bicycle -$3.50

= 75%($160) -$3.50

= $120 -$3.50

= $116.50

Answer:

16.8

Step-by-step explanation:

just look at the length to the side of it (the "28") and look at the given answers. 4 seems way too small and because the line is shorter than 28 it cant be 43, so 16.8 is the most reasonable option.
