See the attached figure
t<span>he angle of the last turn was angle alfa in the point C
tan(alfa)=3/3.5=0.8571
alfa=arctan(0.8581)=40.60</span>°
<span>Round to the nearest degree---------> alfa=41</span>°
the answer is 41°
Answer: Total cost at Aqua town = 4.50+0.75x
Total cost at Splash world = 2.50+1.25x
Step-by-step explanation:
Total cost = Admission charge + Charge per ride x Number of rides
Let x= Number of rides.
Aqua town charges 4.50 admission plus 0.75 for each ride.
Total cost at Aqua town = 4.50+0.75x
Splash world is 2.50 admission plus 1.25 per ride.
Total cost at Splash world = 2.50+1.25x
The required expressions:
Total cost at Aqua town = 4.50+0.75x
Total cost at Splash world = 2.50+1.25x
25%... so yea it's just 25/100 that's 1/4 which is 25%
The domain and range is [-4, 4] and [0, 4]
<h3 /><h3>What is Domain and range?</h3>
The domain of a function is the set of values that we are allowed to plug into our function.
The range of a function is the set of values that the function assumes.
x² + y² = 16
y = √16 - x²
For domain under root should not be negative quantity,
16 - x²≥0
16≥x²
So, x≤4 or x≥4
Thus, the domain is [-4, 4]
Range:
y is maximum at x=0, y=4
y is minimum at x=4, y=0
Thus, range = [0, 4]

I understand now, it is 180 degrees.
