Answer: 
Step-by-step explanation:
Given
The tower is at a height of 
the angle of depression is 
Suppose the surfer is x ft away from the base of the tower

Therefore, the surfer is at a distance of 19.31 ft from the base of the tower.
Y= ∛(-x) - 3
for x = -8 → y = ∛-(-8) - 3 ↔ y = 2-3 ↔y = -1
for x= 8 → y= ∛(-8) - 3 ↔ y = -2 -3 ↔ y = -5
Then - 5≤ y≤ - 1
hence the range of y is {y|-5≤y≤-1}
Answer:
y=3x-1/5
Step-by-step explanation:
we have to move 1/5 to the other side
Answer:60
90-30=60
Step-by-step explanation:
Answer:
You both together can make 48 desserts in 20 minutes.
Step-by-step explanation:
It is a proportion.
5 minutes = 12 desserts
20 minutes = x desserts
Now let's form a proportion and find the value of "x"
5/20 = 12/ x
Cross multiplying, we get
5x = 240
Dividing both sides by 5, we get
x = 240/5
x = 48
You together can make 48 desserts in 20 minutes.
Hope this will helpful.
