Answer:

f(-4) = 5

Step-by-step explanation:

Explanation of

      _

     |   5,             x < -3

f(x) | 2x² - 4,       -3 ≤ x ≤ 4

     | 1 - 6x ,       x > 4

     _

When the x in f(x) is less than -3 than f(x) = 5

When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4

When the x in f(x) is greater than 4 than f(x) = 1 - 6x

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now that we know this lets look back at the question.

We want to find f(-4).

Looking at the piece wise function we see that f(-4) follow x < -3 as "x" or -4 is less than -3. When x is less than -3, f(x) = 5, hence f(-4) = 5

Write a recursive formula for
algol13

9514 1404 393

Answer:

  • a[1] = 3
  • a[n] = a[n-1] -7

Step-by-step explanation:

A recursive formula consists of two parts:

  • initialization (rule for the first term(s))
  • rule for the next term

When we look at the differences between terms in the sequence 3, -4, -11, ..., we find that they are constant at -7. That is each term can be found from the previous one by subtracting 7. This is our recursive rule. The first term is obviously 3, so the recursive formula is ...

  a[1] = 3

  a[n] = a[n-1] -7

Solve for F in terms of K:<br><br> <img src="https://tex.z-dn.net/?f=K%3D%5Cfrac%7B5%7D%7B9%7D%28F%2B459.67%29" id="TexFormula1"
Pepsi [2]

Answer:

see explanation

Step-by-step explanation:

Multiply both sides by 9 to eliminate the fraction

9K = 5(F + 459.67) ← divide both sides by 5

F + 459.67 = \frac{9}{5} K ( subtract 459.67 from both sides )

F = \frac{9}{5}K - 459.67
