Melissa used 4 cups of sugar to bake 54 cookies. If she’s only used 1 cup of sugar, what would be an equivalent ratio of cups to

daser333 [38]

Answer:

$\frac{2}{27}$

Step-by-step explanation:

We have given that melissa used 4 cups of sugar to bake 54 cookies.

That means 1 cup of sugar will be used to bake $\frac{54}{4}=\frac{27}{2}$ by unitary method

We have to find the ratio of cups to the cookies

We are using 1 cup of sugar

And cookies will be $\frac{27}{2}$

$\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}$

What is f(2) if the linearization of f(x) at a = 2 is l(x) = 12x + 4?

Sliva [168]

The linearization at f(a) is
.. l(x) ≈ f(a) +f'(a)*(x -a)
Then
.. l(a) = f(a)

f(2) = l(2) = 12*2 +4
f(2) = 28
