1)
x^-3y^-12 / x^15y^-15
answer is D. last choice
2)
answer is <B'C'D' (third choice)
4)
equivalent 3/9 = 0.33333(3 repeat)
answer is B. second choice
5)
1.7 x 3.5 = 5.95
10^-13 x 10^25 = 10^12
so
= 5.95 x10^12
answer is D. last choice
Answer:
b or g
Step-by-step explanation:
because u shade it and read it
3) We have
which has vertical asymptotes (i.e. infinite discontinuities) whenever the denominator is zero. This happens for
(where is any integer)
So the graph of has vertical asymptotes whenever and .
4) Given
we have the one-sided limits
and
The one-sided limits don't match, so the two-sided limit does not exist. In other words, the limit does not exist at because the function approaches different values from the left and right side of .
Remark
Three angles add to 180o.
The smallest angle = x
The middle angle = 2x
The largest angle = 3x
Solve
x + 2x + 3x = 180
6x = 180
x = 180 / 6
x = 30
Answers
The smallest angle is 30
The middle angle is 30*2 = 60
The largest angle is 30*3 = 90
This is a 30 - 60 - 90 right triangle
