If s = 1/4 unit and A = 80s^2
A = 80 (1/4)^2
A = 80 (1/16)
A = 5
Answer
5 square units
Answer: 3
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
This is false. We can disprove this by plugging in the number into the function f(x) = lnx
f(0) = ln0
Since 
, 
This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.
Answer:
157.6m
Step-by-step explanation:
Given
Horizontal distance = 181m
Length of the rope =240m
To know how high above Kayla was, we will use the Pythagoras theorem.
According to the theorem;
d² = x²+y²
x is the horizontal distance
y is the vertical distance
d is the length of the rope
Substitute
240² = 181²+y²
y² = 240²-181²
y² = 24839
y = √24839
y = 157.6m
Hence the boat is 157.6m above Kayla
