Answer:

Option (3)

Step-by-step explanation:

Explicit formula of the sequence is,

a_n=3^n+4

From this explicit formula,

First term of the sequence will be,

a_1=(3^1)+4

a_1=7

Second term of the sequence,

a_2=(3^2)+4

a_2 = 13

3rd term of the sequence,

a_{3}=(3^3)+4

   = 31

Sequence formed,

7, 13, 31 ..........

From the given options,

Recursive formula,

a_n=3a_{n-1}-8

a_2=3(a_1)-8

a_2=3(7)-8

a_2=21-8 = 13

a_3=3a_2-8

a_3=3a_2-8

a_3=3(13)-8

    = 39 - 8

    = 31

Sequence formed from this recursive formula will be,

7, 13, 31........

Therefore, Option (3) will be the answer.

A 22 gram sample of a substance that's used to preserve fruit and vegetables has a k-value of 0.1011. Find the substance's half-
Eddi Din [679]
 <span>Formula for exponential decay is: 

N = No * e^-kt 

N = 1/2(45) = 22.5 

No = 45 

k = 0.1109 
The solution to your problem is as follows:

Let's try to solve the half-life if it is 45 grams, after which, you will now have an idea on how to solve the problem.

22.5 = 45 * e^(-0.1109t) 

1/2 = e^(-0.1109t) 

ln(1/2) = -0.1109t 

t = (ln(1/2))/(-0.1109) = 6.25 days


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

What is the y intercept to the question below<br><br> y=8x+7 (20 points)
irga5000 [103]

Answer:

7 is your answer

Step-by-step explanation:

Note the slope-intercept form:

y = slope(x) + y-intercept (or y = mx + b)

b is the y-intercept.

In this case, 7 is in the place of b, so 7 is your answer
