Answer:
In parametric form:
Step-by-step explanation:
We first find the mid point:
Then, a vector parallel to the z-axis is:
Then remember the equation of a line passing through point
and parallel to the vector
is:
So, in this problem we get:
After combining the two vectors:
In parametric form:
Answer:
A
Step-by-step explanation:
you just foil them together and get that
Answer:
x = ± 2
Step-by-step explanation:
Given
12 - x² = 0 ( add x² to both sides )
12 = x² or
x² = 12 ( take the square root of both sides )
x = ±
= ±
= ± 2

so, that gives you the compounded amount, after 10 years, if you want to know how much interest was earned? well, just subtract the Principal from the Amount, or A - P <--- that's how much interest was earned
Answer:
2x+3y+5
Step-by-step explanation:
Firstly, we remove the parenthesis since there is nothing in front of it.
There is a “+” sign in front of the parenthesis, it stays the same.
Secondly, we combine like terms. We combine the x’s, the y’s, and the normal numbers without a variable.
Finally, after combining the like terms. You end up with “2x+3y+5”.
