Question

Help Me please!

Answer 1

Tony has been planting strawberries in a garden in his backyard. Tony started with strawberries in one square foot of garden modeled by the function s(x) = 20. He is allowed to convert more of the garden, and each additional square foot he maintains allows his strawberry plants to produce more by a rate of a(x) = 1.2x-1.

Explain to Tony how to create an equation to predict the number of strawberries he can expect based on the number of square feet he maintains. Describe how to determine the number of strawberries he will grow with 15 square feet. Use complete sentences.

Answer 2

This is like the last problem I helped you on. Let the out final function be f(x).
So, at f(1), 1 square foot, he was 20 strawberries.
f(x) = 20 + .....
And for every square foot more, we will add that to f(x) to figure out the amount of strawberries at x square feet.
f(x) = 20 + 1.2(x-1)

Answer 3

f(1) = 20 + 1.2(1-1) = 20; as we expected

Answer 4

lol I love you Josh! wait, I thought you helped me with Missy is organizing the seating arrangements for a concert in her local park. The first row's seats are modeled by the function f(x) = 10. To give everyone a good view, each row must have two more seats than the row before it. The number of additional seats a row has is modeled by the function s(x) = 2(x - 1).

Explain to Missy how to create an equation to predict the number of seats in any row. Describe how to determine the number of seats in the twentieth row. Use complete sentences.

Answer 5

I gave you this answer in a DM.

Answer 6

lol ik, and im sorry I forgot I thought i asked you to help me with the missy one not the tony one..im an idiot.

Answer 7

Well, I helped with both. XP

Answer 8

wait....omg u did?? can you explain the missy one to me again?? im really sorry. lol

Answer 9

It should be in your inbox, right? o.o

Answer 10

Oh, hold on. I'll paste my message here

Answer 11

thank you!!! XD

Answer 12

Your overall function will be 2(x-1) + 10.
Do you see when you plug in 1 for x, you will get 10 as answer? x=1 represents the first row.
x=20 will represent the 20th row.

Similar to the strawberry one.

Answer 13

thank you! Could you help me with one more, just one more????? Please Josh you're the best!!!

Answer 14

Ok.

Answer 15

omg you're a lifesaver!

Tom has taken out a loan for college. He started paying off the loan with a first payment of $200. Each month he pays, he wants to pay back 1.2 times as the amount he paid the month before. Explain to Tom how to represent his first 30 payments in sigma notation. Then explain how to find the sum of his first 30 payments, using complete sentences. Explain why this series is convergent or divergent.

Answer 16

thanks btw for the medal

Answer 17

Omg, this is calc 2. ._.

Answer 18

nah uh it's algebra 2. lol

Answer 19

\[\sum_{n = 1}^{30} 1.2(n-1) + 200\]

Answer 20

That Greek letter is a capital sigma, it means summation. When n=1, the answer equals 200, his first payment.
So, they want you to add up the answer you get when you plug in n from 1 to 30. :3

Answer 21

It should be convergent since we're going up a fixed amount, n = 1 to 30.

Answer 22

XD you need to be a math teacher lol. Thank you so much Josh!!! You've like saved my life! And I will repay you most definatley

Answer 23

No prob.

Answer 24

wouldn't it be summation of 200*1.2^(n-1)?

Answer 25

@SarahEZZMcK can u tell me what u got for the missy and tony questions? i only have 30 mins left to complete this and these are the only 2 quetions i dont understand

Answer 26

I dont remember love, this was last year
