Step-by-step explanation:

Estimation would give you an answer close to the actual answer so you can see if your answer is reasonable depending on how close the estimate is
The hypotenuse can be solved by this formula. X^2 = 6^2 +6^2
X^2=64
Usually you cut it down to 8 but it wants the squared form so 64.
7×10^7 = 70000000 (10^7 = 10000000)

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set
. In other words, we define the y-intercept (let's call it
as:

Setting
in our function we have:

So <em>in this context the y-intercept is -16</em>
