Answer:
Domain { 0 ≤ r≤ 18}
Range = {0≤ c ≤ 31.5}
Step-by-step explanation:
The domain is the values that r can take
He can goes on each ride up to 1 time
R can be from 0 rides to 18 rides since there are only 18 rides
Domain { 0 ≤ r≤ 18}
The range is the output
If r = 0 then he spends no money
if r =18 then 1.75*18 =31.5
Range = {0≤ C(r) ≤ 31.5}
Am sorry I really need this point sorry again
If ABCD is a square, then m∠A = 90°.
Therefore we have the equation:
30° + 48° + x° = 90°
78° + x° = 90° |-78°
x° = 12°
Answer: 12
Answer:
Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions. Two lines are skew if and only if they are not coplanar.
