determine if the sequence is geometric or arithmetic and find the ratio or difference. -1, 6, -36, 216

Answers

Answer 1

Answer: The sequence is an geometric progression;
Nth=a₁r^(n-1)
a₁ is the first term=-1
r=ratio=a₂/a₁=6/-1=-6

Nth=-1(-6^(n-1)

NTh=an

a₁=-1(-6⁰)=-1
a₂=-1(-6¹)=6
a₃=-1(-6²)=-36
a₄=-1(-6³)=216

therefore this serie is rising at an increasing fast speed, it is an geometric progression.

Fish are sold at 10 for $8.64. What will be the cost of 16 fish

Answers

The cost of 16 fish would be $13.824.

How to determine What will be the cost of 16 fish

To find the cost of 16 fish, we can set up a proportion based on the given information:

10 fish cost $8.64

So, 1 fish would cost $8.64 / 10 = $0.864

Now, we can find the cost of 16 fish:

Cost of 16 fish = 16 × $0.864 = $13.824

Therefore, the cost of 16 fish would be $13.824.

A satellite television company charges a one-time installation fee anda monthly service charge. The total cost is modeled by the function
y = 40 + 90x. Which statement represents the meaning of each part
of the function?
(1) y is the total cost, x is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.
(2) y is the total cost, x is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(3) x is the total cost, y is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(4) x is the total cost, y is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.

Answers

Answer:

Option (2).

Step-by-step explanation:

A satellite T.V. company charges one time installation fees along with monthly service charge.

Total cost is modeled by the function y = 40 + 90x

Here y = Total cost charged by the company

A one time installation charges = $40

Service charge for a month = $90

and number of months for which service was used = x months

Therefore, Option (2) explains the function well.

the answer is 2 y= total installation cost. x is the variable representing the number of months of service and $40 is the fixed price while $90 is dependent on the xvalue
