The first term of a geometric sequence is −8100 . The common ratio of the sequence is −0.1 .
What is the 6th term of the sequence?
Answer:
-8100 x (-0.1)5
Step-by-step explanation:
The 6th term of the sequence is -0.081.
What is geometric sequence?A geometric sequence can be defined as the sequence of numbers where any two consecutive terms have the same ratio. This ratio is called the common ratio of the sequence.
Given that,
The first term of the geometric sequence is, a₁ = -8100.
The common ratio is r = -0.1.
The general expression for the nth term is given as,
aₙ = a₁rⁿ⁻¹
Substitute n = 6 to obtain,
a₆ = -8100 × (-0.1)⁶⁻¹
= -8100 × (-0.1)⁵
= -0.081
Hence, the 6th term of the given sequence is -0.081.

For her cell phone plan, heather pays $30 per month plus $0.05 per month plus $0.05 per text. She wants to keep her bill under $60 per month. Which inequality represents the number of texts, t, Heather can send each month while staying within her budget?
A. T> 600
B. T<600
Answer:
A
Step-by-step explanation:
Answer: B. T<600
Step-by-step explanation:
if the monthly plan is $30, we subtract that from $60 to get that she has $30 left. Then divide 30 by 0.05 to get exactly 600. but, you can’t forget that other $0.05 per month so it would have to be less than 600 texts

The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

Basically what you do is multiply the distance by the time, for example:
7 1/2 miles = 1/2 hour
so to get the amount of miles in one hour you get the miles and times it by two so it would go like this:
7 1/2 | 15 |
= | = |
1/2 | 1 |
then for one and a half you get the 1 hour answer and add the first one like this:
22.5 miles = 1 1/2 miles
and you continue that pattern!!! If you need more help just reply to this answer i'm in 7th grade so i can help with this stuff

Represent the measurement of angle B in the figure.
In the figure, angle A and angle D are complementary. The measurement of angle D is 45°. Complete the equation to solve for b, the measurement of angle B.
180 = __ + (90 –__ ) + b
Answer:
angle b is 45° as it is alternative angle of d so equal to d.
Step-by-step explanation:
now....
180 = 90+(90-45)+b
90+45+45
90+90
