Answer:

IF TWO VALUES ARE <u>PROPORTIONAL</u> THEY CAN BE CONNECTED IN TERMS OF k BY MAKING THEM IN A STUCTURE OF AN EQAUTION LIKE GIVEN BELOW. HERE AS THE PROPORTIONAL VALUES ARE<u> RADIUS</u> AND <u>CIRCUMFERENCE </u>WE USE THE GIVEN VALUES AND CREATE EQAUTION LIKE BELOW

r=kC

⇒WE CAN TRASNPOSE THIS TO GET

kC/r=0

⇒C/r=1/k

RECIPROCATE IT TO GET

⇒r/C=k

Maybe this will be correct answer

Answer:

C = kr

Step-by-step explanation:

Given the circumference (C) is directly proportional to r , then the equation relating them is

C = kr ← k is the constant of variation

p2-5p-24=0  

Two solutions were found :

    p = 8

    p = -3  

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "p2"   was replaced by   "p^2".  

Step by step solution :

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  p2-5p-24  

The first term is,  p2  its coefficient is  1 .

The middle term is,  -5p  its coefficient is  -5 .

The last term, "the constant", is  -24  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -24 = -24  

Step-2 : Find two factors of  -24  whose sum equals the coefficient of the middle term, which is   -5 .

      -24     +     1     =     -23  

      -12     +     2     =     -10  

      -8     +     3     =     -5     That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -8  and  3  

                    p2 - 8p + 3p - 24

Step-4 : Add up the first 2 terms, pulling out like factors :

                   p • (p-8)

             Add up the last 2 terms, pulling out common factors :

                   3 • (p-8)

Step-5 : Add up the four terms of step 4 :

                   (p+3)  •  (p-8)

            Which is the desired factorization

Equation at the end of step  1  :

 (p + 3) • (p - 8)  = 0  

Step  2  :

Theory - Roots of a product :

2.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

2.2      Solve  :    p+3 = 0  

Subtract  3  from both sides of the equation :  

                     p = -3

Solving a Single Variable Equation :

2.3      Solve  :    p-8 = 0  

Add  8  to both sides of the equation :  

                     p = 8

Bob's Bagels sells 7 bagels for $8.00, and Betty's Bagels sells 9 bagels
puteri [66]

Answer:

3 of 4

The better deal will have the higher ratio of dollars per bagel.

To find the better deal, you must compare the fractions<u> 8/7 and 6/9. </u>

Comparng the fractions reveals that <u>Betty</u> has the better deal

Step-by-step explanation:

bobbs bagels: 8/7 equals 1.14, so each bagel would cost about $1.14

bettys bagels: 6/9 equals 0.66, so each bagel would cost about $0.66

$0.66 is better than $1.14 per bagel. therefore, bettys bagels are cheaper

hope this helps :)
