1. According to the plots, the curves intersect when
and
.
We can confirm this algebraically.





(where
is an integer)


We get the two solutions we found in the interval [0°, 360°] with
in the first case, and
in the second case.
2. We have
when
. For the given plot domain [0°, 360°], this happens when
.
3. The domain for both equations is all real numbers in general, but considering the given plot, you could argue the domains would be [0°, 360°].
is bounded between -1 and 1, so
is bounded between -1 + 2 = 1 and 1 + 2 = 3, and its range is [1, 3].
Likewise,
is bounded between -1 and 1, so that
is bounded between -1 + 3 = 2 and 1 + 3 = 4, so its range would be [2, 4].
Answer:
Step-by-step explanation:
Alright, lets get started.
The original photo size is 4 inches wide and 6 inches tall.
So, the ratio of width and height will be = 
The new enlarged photo will be of the same ratio means 2:3
The width of enlarged photo is given as 12 inches.
Suppose new height of enlarged photo is H, so

Cross multiplying

Dividing 2 in both sides
inches
So the height of new enlagred photo will be 18 inches. : Answer
Hope it will help :)
Answer:
Answer E. is correct
Step-by-step explanation:
b = 3 * c --> c = 1/3 * b
c + 3 = 1/3 * b + 3 --> E.
Divide total price by quantity:
15.60 / 6 = 2.60
Unit price = $2.60
