Answer:

Answer:

The first four terms of the sequence are: {-10,-23,-62,-179}

Step-by-step explanation:

Given recursive formula is:

a_n = 3a_(n-1)+7

First term = a1 = -10

The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.

Putting n=2

a_2 = 3a_(2-1)+7\na_2 = 3a_1+7\na_2 = 3(-10)+7\na_2 = -30+7\na_2 = -23

Putting n=3

a_3 = 3a_(3-1)+7\na_3 = 3a_2+7\na_3 = 3(-23)+7\na_3 = -69+7\na_3 = -62

Putting n=4

a_4 = 3a_(4-1)+7\na_4 = 3a_3+7\na_4 = 3(-62)+7\na_4 = -186+7\na_4 = -179

Hence,

The first four terms of the sequence are: {-10,-23,-62,-179}

Answer:

Let fertilizer be F

and peat moss be P

since F is proportional to P

F = kP

where, k = constant of proportionality

k = F/P

putting in the values,

k = (3/4) /12

k = 3/4 * 1/12

k = 1/16

Therefore the constant of proportionality is 1/16.

Find the value of z such that 0.11 of the area lies to the right of z. Round your answer to two decimal places.

Answers

Final answer:

To find the value of z such that 0.11 of the area lies to the right of z, use the standard normal probability table. The value of z is approximately 1.96.

Explanation:

To find the value of z such that 0.11 of the area lies to the right of z, we can use the standard normal probability table. The area to the right of z is equal to 1 minus the area to the left of z.



Using the information given, the area to the left of z that corresponds to a value of 0.025 is 0.975. The area to the left of 1.96, which can be found using the standard normal probability table, is 0.975.



Therefore, the value of z is approximately 1.96.

John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour. How many kilowatt hours can he use and keep his monthly cost no more than $109

Answers

Answer:

71.63 kilowatts hours

Step-by-step explanation:

We are told in the question:

John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour.

We are to find, How many kilowatt hours can he use and keep his monthly cost no more than $109.

Step 1

$109 - $20.90

= $88.1

$88.1 is the amount left to spend on killowatts of electricity per hour after removing the normal monthly electricity bill in a month

Step 2

$1.23 = 1kilowatts per hour

$88.1 = y kilowatts per hour

Cross Multiply

= $1.23 × y kilowatts per hour = $88.1 × 1 kilowatts per hour

y kilowatts per hour = $88.1 × 1 kilowatts per hour/ $1.23

= 71.62601626kilowatts hour.

Approximately = 71.63 kilowatts hour

Therefore, John can use 71.63 kilowatts per hour and keep his monthly cost no more than $109

Answer:

71

kilowatt hours can he use and keep his monthly cost no more than $109
