Let us model this problem with a polynomial function.

Let x =  day number (1,2,3,4, ...)
Let y = number of creatures colled on day x.

Because we have 5 data points, we shall use a 4th order polynomial of the form
y = a₁x⁴ + a₂x³ + a₃x² + a₄x + a₅

Substitute x=1,2, ..., 5 into y(x) to obtain the matrix equation
|   1     1    1    1    1  |  | a₁ |      | 42 |
| 2⁴  2³  2²  2¹  2⁰  |  | a₂ |      | 26 |
| 3⁴  3³  3²  3¹  3⁰   |  | a₃ |  =  | 61 |
| 4⁴  4³  4²  4¹  4⁰   |  | a₄ |      | 65 |
| 5⁴  5³  5²  5¹  5⁰  |  | a₅ |      | 56 |

When this matrix equation is solved in the calculator, we obtain
a₁ =      4.1667
a₂ =  -55.3333
a₃ =  253.3333
a₄ =  -451.1667
a₅ =   291.0000

Test the solution.
y(1) = 42  
y(2) = 26
y(3) = 61
y(4) = 65
y(5) = 56

The average for 5 days is (42+26+61+65+56)/5 = 50.
If Kathy collected 53 creatures instead of 56 on day 5, the average becomes
(42+26+61+65+53)/5 = 49.4.

Now predict values for days 5,7,8.
y(6) = 152
y(7) = 571
y(8) = 1631

What value of c makes the equation true?<br><br><br><br> −3−3/4(c−4)=5/4
Anuta_ua [19.1K]
C = -5/3 = -1 2/3



Write down the equation and solve for c

-3 - 3/4(c-4) = 5/4



Distribute the 3/4

-3 -(3/4)c + 3 = 5/4



Perform the addition of -3 and 3

-(3/4)c = 5/4



Divide both sides by -(3/4)

c = 5/4 / (-3/4) = 5/4 * (-4/3) = -20/12 = -5/3



So the value of c is -5/3. Let's verify it.

-3 - 3/4(-5/3 - 4) = x



Distribute the -3/4

-3 - (3/4)(-5/3) + (3/4)4 = x

-3 +15/12 + 3 = x



Combine terms

15/12 = x



Simplify

5/4 = x
