Zina spends 1.5 hours setting up her sewing machine and making one hat. The total amount of time spent making hats can be represented by the sequence below.1.5, 2.25, 3.0, 3.75, ...

Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously?

A. f(n + 1) = f(n) + 1.5
B. f(n + 1) = f(n) + 0.75
C. f(n + 1) = f(n)
D. f(n + 1) = f(n)

$\implies d=kv^2$

substitute the given values, $5=k(10)^2\implies k=\frac1{20}$

now, $d=\frac{1}{20}\times( 70)^2=\frac{70\times70}{20}=245$

A big blunder from my side, now fixed!

Answer:

2x+8y=20;y=2  

Solution :

{x,y} = {2,2}  

System of Linear Equations entered :

  [1]    2x + 8y = 20

  [2]    y = 2

Graphic Representation of the Equations :

   8y + 2x = 20        y = 2  

Solve by Substitution :

// Solve equation [2] for the variable  y  

  [2]    y = 2  

// Plug this in for variable  y  in equation [1]

  [1]    2x + 8•(2) = 20

  [1]    2x = 4

// Solve equation [1] for the variable  x  

  [1]    2x = 4  

  [1]    x = 2  

// By now we know this much :

   x = 2

   y = 2

We are done

Solution :

{x,y} = {2,2}

Answer:

The output value of f(-2) is, 14

Step-by-step explanation:

Given the function:

            ......[1]

We have to find the output of f(-2).

Substitute x = -2 in [1] we have;

⇒

Simplify:

therefore, the output value of f(-2) is, 12
