Answer:
the value of 3 in 0.3947 is TENTHS
x=1 or x= 12
Step-by-step explanation:
x²-13x+12=0
x²-12x-x+12=0
x(x-12)-1(x-12)=0
(x-1)(x-12)=0
x-1=0 or x-12=0
x=1 or x=12

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
