Answer:
a) No
b) Yes
Step-by-step explanation:
a) The value Temp = 2 maps to more than one value of Time, so Time is NOT a function of Temp.
b) Each value of Time only maps to one value of Temp, so Temp IS a function of Time.
First Question
A is not correct. If you have one point, you wouldn't know where the line would extend. You need at least two points to determine a line. You need at least three points if you don't know if the line is linear.
B is correct. A ray has one endpoint and extends infinitely in one direction.
C is not correct. A line segment has two endpoints and does not extend infinitely.
D is not correct because a line is infinitely extending. It has no endpoints.
Second Question
A is not correct. Skew lines are two or more lines that do not intersect, are not parallel, and are not coplanar.
B is correct. Perpendicular lines must intersect at a right angle.
C is not correct. Two parallel lines can lie in the same plane.
D is not correct. A transversal is a line that intersects two or more other lines. This does not have to be four other lines (but it can).
Answer:
OC. $57.28
Step-by-step explanation:
It depends on how much she sells them for.
Let's say Anne sells them for $x.
Then her profit is:
8x-(8*7.16)
=8x-57.28
To make a minimum to at least make even is $57.28 and sell for $7.16 a piece.
Answer:
A=54
Step-by-step explanation:
A=
Use u subsitution
the derivitive of eˣ+2 is eˣ
u=eˣ+2
du/dx=eˣ
du=eˣdx
we see a eˣdx in the problem
sub du for that and u for eˣ+2
remember
sub eˣ+2 for u
don't forget to add a constant since the derivitive of a constant is 0
the original function is
where C is a constant
