Greta must volunteer 225 hours for a community service project. She plans to volunteer for 6 hours
klemol [59]

Answer:

A. "an arithmetic sequence with a common difference (d) of -6."

B. 33 hours

C. a_n=a_1+(n-1)d

D. See below

Step-by-step explanation:

A.

Since the sequence lessens by 6, this is an arithmetic sequence with a common difference (d) of -6.

B.

The formula for term of arithmetic sequence is:

a_n=a_1+d(n-1)

Wher a_1 is the first term and d is the common difference. Since we want to find after 33 weeks, we plug in 33 into n:

a_{33}=225 + (-6)(33-1)\\a_{33}=33

She will have left 33 hours

C.

We will use the arithmetic sequence term formula written above, that is:

a_n=a_1+(n-1)d

THis gives us the amount of hours left after a certain number of weeks.

D.

We plug in 40 into n and find the hours left:

a_{40}=225+(40-1)(-6)\\a_{40}=225-234\\a_{40}=-9

THis term is NEGATIVE, which means that Greta will not have to work 40 weeks to fulfill the target of 225 hours. She needs to work less.

The examples and solutions to the functions are illustrated below based on the information given.

<h3>How to illustrate the functions?</h3>

1st example: The cost of a bag of rice is $100 and subsequent bags cost $95. Illustrate. the function to calculate the cost for p bags of rice.

The function will be:

C = 100 + (95 × p)

C = 100 + 95p

<u>2nd example:</u><u> </u>The cost of a pen is $5. Find the cost of s pens.

The function will be:

C = 5 × p

C = 5p

<u>3rd example</u>: Calculate the total amount for m tickets if each ticket is $20.

The function will be;

C = 20 × m

C = 20m

<u>4th example:</u> Bon bought g mangoes at $2 each and d oranges at $3.40 each. Calculate the total cost.

C = (2 × g) + (3.40 × d)

C = 2g + 3.4d

<u>5</u><u>t</u><u>h</u><u> </u><u>example</u><u>:</u><u> </u>The average age of k number of boys is 7. Find their total age.

The function will be:

a = (7 × k)

a = 7k
