The dependent variable is the cost of the pizza.
The Independent variable (or what you manipulate) is the toppings of the pizza, and the dependent variable (or what changes because you manipulated something) is the total cost of the pizza
Answer:

Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to

The y-intercept is equal to

so
substitute the given values

For this case we have the following expression:

By definition of properties of powers and roots we have to:
![a ^ {\frac {m} {n}} = \sqrt [n] {a ^ m}](https://tex.z-dn.net/?f=a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D%20%3D%20%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D)
Then, we can rewrite the expression as:
![\sqrt [8] {4 ^ 3}](https://tex.z-dn.net/?f=%5Csqrt%20%5B8%5D%20%7B4%20%5E%203%7D)
Answer:
![4 ^ {\frac {3} {8}} = \sqrt [8] {4 ^ 3}](https://tex.z-dn.net/?f=4%20%5E%20%7B%5Cfrac%20%7B3%7D%20%7B8%7D%7D%20%3D%20%5Csqrt%20%5B8%5D%20%7B4%20%5E%203%7D)
Answer:
10√2
Step-by-step explanation:
Lets cut the square into a triangle, making a line from one corner to another, then let's see what we have.
We shoupd have a triangle where we don't know the hypotenuse, which we can find using the formula: a^2 + b^2 = c^2
so:
10^2 + 10^2 = c^2
100 + 100 = c^2
c^2 = 200
now let's square root what we got
√200
there are 2 10's in 200, which will turn the equation to:
10√2
this can't be simplified further, so our answer is 10√2
