By definition, an astronomical unit in miles is given by:

As it is in exponential notation, then we must rewrite.

Therefore, an astronomical unit is:
93 million miles

Answer:
1
Step-by-step explanation:
We have the function

and we want to know the value of
.
The first step is to find
; we can subtract 1 from it at the end! But what does
mean?
Basically, we're saying <em>"what is the value of the function when </em>
<em> ?"</em>
So, we simply replace
with 3 in the function, and we get:
.
Finally, we subtract 1 to find
.
Answer:
Volume= lxwxh
12 x 10 x 6= C
720 ft
Step-by-step explanation:
You are given the height of the building and the length of the shadow the building gives, so you can set that up as a proportion of Height of building over the length of the shadow so 31/28.
Now you can set the same proportion for Julian, using X for her height, so you would have x/6.
To solve for her height, set the two proportions equal and solve for x:
31/28 = x/6
Cross multiply:
31 * 6 = 28 *x
186 = 28x
Divide both sides by 28:
x = 186 / 28
x = 6.64 feet tall
