Find the value of f(-1) for the function below

mrs_skeptik [129]

Put the value of x = -1 to the equation of a function f(x):

$f(x)=\dfrac{2}{3}\times3^{3x+12}\\\\f(-1)=\dfrac{2}{3}\times3^{3(-1)+12}=\dfrac{2}{3}\times3^{-3+12}=\dfrac{2}{3}\times3^9=\dfrac{2}{1}\times3^8=13,122\to\boxed{B.}$

inessss [21]

Answer:

The answer is "94"

Step-by-step explanation:

Given data:

51,54,64,68,72,74,76,83,94,94,99

Find:

$P_{75}=?P_{75}= (\frac{75(n+1)}{100})^{th} \ \ observation\\\\$

$= (\frac{75(11+1)}{100})^{th} \ \ observation\\\\= (\frac{75(12)}{100})^{th} \ \ observation\\\\= (\frac{75 \times 12}{100})^{th} \ \ observation\\\\= (\frac{900}{100})^{th} \ \ observation\\\\= 9^{th} \ \ observation\\\\= 9^{th} \ number \ is = 94$

If mc008-1.jpg, what is f(5.9)?

yulyashka [42]

The answer:

the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?

9
10
11
12

first, [x - 2 ] is called the integer part of x-2,
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so f(5.9) = 3 [ 5.9 - 2 ] = 3 [ 3.9 ]

as we know that [ 3.9 ]=3

therefore
3 [ 3.9 ]= 3x3 =9

the answer is 9
