Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R

A pizzeria uses a 3-pound bag of cheese to make 8 pizzas. Use the given ratio to compute the number of pizzas the pizzeria can m

Arada [10]

Answer:

18 pounds = 48 pizzas

18 pounds = 48 pizzas 22.5 pounds = 60 pizzas

18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas

Step-by-step explanation:

1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)

2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)

3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)

What is the inverse of f(x)=e^x

enot [183]

Answer:

$f^{-1}(x)=\ln{x}$

Step-by-step explanation:

An <em>inverse</em> function is any function that "undoes" another function. If we think of the function $f$ as some kind of machine that takes in a number $x$ as input and produces a number $f(x)$ as an output, when we give inverse function $f^{-1}$ the number $f(x)$ as in input, we get $x$ , our original input, as the output $f^{-1}(x)$

We need a function that undoes $f(x)=e^x$ , and the natural choice for undoing an exponent is with a logarithm. Here, our base is $e$ , so we'll choose $\log_e{x}=\ln{x}$ as our inverse function. Let's see how that works:

$f^{-1}(f(x))=\ln{e^x}$

$\ln{e^x}$ is the power we have to raise $e$ to to get $e^x$ , which is $x$ , so

$f^{-1}(f(x))=\ln{e^x}=x$

And we have our function.
