What Is The Recursive Formula For This Geometric Sequence? 6, -24, 96, -384, ...

Answers

Answer 1

Answer:

Option (C)

Step-by-step explanation:

Geometric sequence has been given as,

6, -24, 96. -384.......

First term of this sequence = 6

[tex]a_1=6[/tex]

Recursive formula of geometric sequence is given by,

[tex]a_n=a_{n-1}(r)[/tex]

Here r = common ratio of successive and previous term

From the given sequence,

r = [tex]\frac{a_2}{a_1}[/tex]

 = [tex]\frac{-24}{6}[/tex]

 = (-4)

Recursive formula of the given sequence will be,

[tex]a_n=a_{n-1}.(-4)[/tex]

Therefore, Option (C) will be the correct option.

3 3/4 = r + 1/8

Answers

Answer:

r = 29/8 or 3 5/8

Step-by-step explanation:

so you need to make them have the same denominator so you multiply 3/4 by 2/2 to get that

this equals 6/8

add 3 so 24/8

then you subtract 1/8 from both sides

r = 29/8

simplify so 29/8 = 3 5/8

Jerome and his brother stayed at the carnival from 4pm to 8pm they spent 90 minutes watching the magic show what percentage of the evening did they spend at the magic show

Answers

Answer:

Percentage of time spend in magic show = 37.5%

Step-by-step explanation:

Given:

Total time 4pm to 8pm = 4 hours = 4 x 60 = 240 minutes

Time spend in magic show = 90 minutes

Find:

Percentage of time spend in magic show

Computation:

Percentage of time spend in magic show = [Time spend in magic show / Total time]100

Percentage of time spend in magic show = [90 / 240]100

Percentage of time spend in magic show = 37.5%

Answer:37.5%

Your grandmother is worried about the heat during the family reunion picnic yesterday between 10 am and noon the temperature rose 6 degrees then between noon and 3pm it rose 4 degrees what was the average rate of increase in temperature between 10am and 3pm

Answers

Answer:

Average rate of temperature increase is 2 degrees per hour

Step-by-step explanation:

Here, we want to calculate the average rate of increase in temperature

From what we have above, we can calculate this by dividing the total temperature rise by the number of hours

The total temperature rise is 6 + 4 = 10 degrees

This means that the temperature rose by 10 degrees between 10 am and 3 pm

The number of hours between 10 am and 3 pm is 5 hours

So the average rate of temperature increase is 10 degrees/ 5 hours = 2 degree per hour

write the equation. the output of a function is 6 more than 2 times the input.

Answers

Answer:

y = 2x+6

Step-by-step explanation:

Let the output value be y

Let the input value be x

the output of a function is 6 more than 2 times the input

2 times the input is expressed as 2x

6 more than 2 times the input is expressed as 2x + 6

Since the output of a function is 6 more than 2 times the input, we will equate y to the resulting equation to have;

y = 2x + 6

Hence the required equation is y = 2x+6

What is the solution to 0.3(12x - 16) = 0.4(12 - 3x)?

Answers

Step-by-step explanation:

The solution is one-solution

.3(12x-16)=.4(12-3x) (you do the distributive property)

3.6x-4.8=4.8-.12x (you add 1.2 to both sides)

3.6x-3.6=4.8 (You add 3.6 to both sides)

3.6x=8.4 ( You divide 3.6 both numbers)

x=0.4285...

Its a one-solution
