Answer:
D, 22x^9
Step-by-step explanation:
Here's a key for end behavior: Look at the leading term
x^even = x -> neg inf, f(x) -> pos inf; x -> pos inf, f(x) -> pos inf
-x^even = x -> neg inf, f(x) -> neg inf; x -> pos inf, f(x) -> neg inf
x^odd = x -> neg inf, f(x) -> neg inf; x -> pos inf, f(x) -> pos inf
-x^odd = x -> neg inf, f(x) -> pos inf; x -> pos inf, f(x) -> neg inf
Looks good! You have the right answers.
However, the graph for 12 and 15 is inaccurate! Because he starts from a stop sign/stop light, the graph's speed should start from the origin!
Not to confuse you or anything, but this means the graph does not follow the description of the problem. Please let your teacher know so s/he can fix the worksheet.
Answer:
n =-19
Step-by-step explanation:
3* (n+7) = -36
Distribute
3n+21 = -36
Subtract 21 from each side
3n+21-21 = -36-21
3n = -57
Divide by 3
3n/3 = -57/3
n =-19
Answer:

Step-by-step explanation:
Notice that
is a right triangle where its hypotenuse is
. We can also see that
. For this we must use the Pythagorean Theorem.
Recall:
The Pythagorean Theorem states that if you have a right triangle, the principal square root of the sum of the squares of each leg is the length the hypotenuse.
We can see that
and 

Origin = (0,0)
To find the units of distance subtract the given pair from origin
(0,4) - (0,0) = 4
