Slav-nsk [51]

The logarithmic model for the length when the strength is of 8 Pascals is given by:

  • f^{-1}(8) = \log_{2}{8} = \log_2{2^3} = 3
  • That is, the length is of 3 units.

<h3>What is the function?</h3>

The strength in Pascals for a building of length x is given by:

f(x) = 2^x

To find the length given the strength, we apply the inverse function, that is:

2^y = x

\log_{2}{2^y} = \log_2{x}

y = \log_2{x}

Hence, when the strength is of 8 Pascals, x = 8, and the length is given by:

f^{-1}(8) = \log_{2}{8} = \log_2{2^3} = 3

What is -11+6x+25-3x
evablogger [386]

Answer:

3 x + 14

Step-by-step explanation:

Simplify the following:

6 x - 3 x - 11 + 25

Grouping like terms, 6 x - 3 x - 11 + 25 = (6 x - 3 x) + (-11 + 25):

(6 x - 3 x) + (-11 + 25)

6 x - 3 x = 3 x:

3 x + (-11 + 25)

25 - 11 = 14:

Answer:  3 x + 14

Answer:

  B.  Up 1 and 2 to the left

Step-by-step explanation:

The second graph (blue) is up 1 and 2 left of the first graph (red).

__

You can compare the given equations to the form ...

  y = a(x -h)^2 +k

For the first graph, we have (h, k) = (6, -1).

For the second graph, we have (h, k) = (4, 0).

Then the amount added to the first to make the second is ..

  (4, 0) -(6, -1) = (-2, 1) . . . . . . a translation 2 left and 1 up
