write the possible range of the measurement 214 ounces +1.2% round to the nearest hundredth if necessary

boyakko [2]

9514 1404 393

Answer:

[211.43,216.57]

Step-by-step explanation:

1.2% of 214 is ...

0.012 × 214 = 2.568 ≈ 2.57 . . . . rounded to hundredths

Then the minimum possible value is ...

214 -2.57 = 211.43

and the maximum possible value is ...

214 +2.57 = 216.57

The range is 211.43 to 216.57.

If f(x)=3x+2,find f(f^-1(14)).

lisov135 [29]

Answer: 14

<u>Step-by-step explanation:</u>

f(x) = 3x + 2

To find f⁻¹, swap the x's and y's and solve for y --> Note: f(x) is y

x = 3y + 2

x - 2 = 3y

$\dfrac{x-2}{3}=y$

$\implies f^{-1}(x)=\dfrac{x-2}{3}$

$\implies f^{-1}(14)=\dfrac{14-2}{3}$

$\implies f^{-1}(14)=\dfrac{12}{3}$

$\implies f^{-1}(14)=4$

f(f⁻¹(14)) = f(4)

f(4) = 3(4) + 2

= 12 + 2

= 14

NOTE: the simplified version is .... f and f⁻¹ cancel out, leaving you with 14
