Answer:

part A) $f=2.75p$

par B) $38.5\ cups\ of\ flour$

Step-by-step explanation:

Part A)

Let

p ----> the number of pounds of cake

f ----> the number of cups of flour

we know that

A relationship between two variables, p, and f, represent a proportional variation if it can be expressed in the form $k=\frac{f}{p}$ or $f=kp$

Find the value of k

For p=3, f=8.25 ----> $k=\frac{8.25}{3}=2.75$

therefore

The linear equation is

$f=2.75p$

Part B) we have

For p=14

substitute in the equation and solve for f

$f=2.75(14)=38.5\ cups$

Express the terms of the following sequence by giving a recursive formula.

MAXImum [283]

The recursive formula for given sequence is: $a_n = a_{n-1}-7$

And the terms will be expressed as:

$a_1 = 11\\a_2 = a_{2-1} - 7 \\a_2= a_1 - 7\\a_2 = 11- 7\\a_2 = 4\\a_3 = a_{3-1} - 7 \\a_3= a_2 - 7\\a_3 = 4 - 7\\a_3 = -3\\a_4 = a_{4-1} - 7 \\a_4= a_3 - 7\\ a_4= -3 - 7\\a_4 = -10\\a_5 = a_{5-1} - 7 \\a_5= a_4 - 7\\a_5 = -10 - 7\\a_5 = -17\\$

Step-by-step explanation:

First of all, we have to determine if the given sequence is arithmetic sequence or geometric. For that purpose, we calculate the common difference and common ratio

Given sequence is:

11,4,-3,-10,-17...

Here

$a_1 = 11\\a_2 = 4\\a_3 = -3\\So,\\d = a_2 - a_1 = 4-11 = -7\\d = a_3-a_2 = -3-4 = -7$

As the common difference is same, given sequence is an arithmetic sequence.

A recursive formula is a formula that is used to generate the next term of the sequence using the previous term and common difference

So, the recursive formula for an arithmetic sequence is given by:

$a_n = a_{n-1} +d\\Putting\ d = -7\\a_n = a_{n-1}-7$

Hence,

The recursive formula for given sequence is: $a_n = a_{n-1}-7$

And the terms will be expressed as:

Digiron [165]

Answer:

Step-by-step explanation:

y = 32 – 1 is not true to (1,2) because y=2 and 2 does not equal 31.
