Answer:
The domains are;
0 < x < 3 for f(x) = 15
3 ≤ x ≤ 7 for f(x) = 22
7 < x ≤ 15 for f(x) = 30
Step-by-step explanation:
The duration the amusement park is opened, t = 15 hours
The number of days the amusement is opened = 7 days a week
The prices for the admission are;
x < 3 hours = $15
3 ≤ x ≤ 7 hours = $22
x > 7 hours = $30
The functions are;
f(x) = 15 when x < 3; The domain = 0 < x < 3
f(x) = 22 when 3 ≤ x ≤ 7; The domain = 3 ≤ x ≤ 7
f(x) = 30 when x > 7; The domain = 7 < x ≤ 15.
Answer:
x≥149.84
Step-by-step explanation:
solve for x the inequality
9.25x - 1201 ≥ 185
9.25x ≥ 185+1201
9.25x ≥1386
x ≥ 149.84

The first graph the X is 45° because it right angle is 90 degrees Larry give us 55 degrees so 55 subtract the equals 45
The second graph has a degree of 113 because 180 subtracted by 67 is 113 because they straight angle has 180.
The first one is 45
The second one is 113
Answer:
132.89 miles
Step-by-step explanation:
Let plane A travel at 130 mph and plane B travel at 150 mph.
After 1.5 hours, the total distance traveled by each plane is:
The law of cosines can be used to find the distance (D) between both planes as follows:
They are 132.89 miles apart after 1.5 hours.
