Answer:
The distance is dependent
Step-by-step explanation:
Time is always the dependent variable because time will always stay the same when other things change, such as distance.
Answer:
15
Step-by-step explanation:
a²+20²=25²
a²=625-400
a²=225
a=15
The <u>Distance Formula</u> =

A(1,1) ⇒ the first 1 is

& the second 1 is

.
B(7,-7) ⇒ the first 7 is

& the second is -7 is

.
Now all you have to do is
SUBSTITUTE the variables into the distance formula to get:

.
After you plug that formula into your graphing calculator (or solve it manually & mentally), you should end up with the answer 10, therefore
d=10.
