Given;
The cross section of the bottom of a circular pound has the shape of a parabola
Now,
For the circular parabola, the equation is given as:
y² = 4ax
here,
y is the depth
x is the horizontal distance from the center
a is the constant
also,
at diameter of the pond = 24 feet
and,
at x = 0 ; y = 8 feet
now,
the point 2 feet from the shore with respect to the center of the pond = radius of the pond - The distance from the shore
= - 2 = 10 feet
thus,
at x = 10 feet ; y = 3 feet
thus,
we have
the equation as:
3² = 4a × 10
or
0.9 = 4a
or
a = 0.225
therefore,
we get the equation as;
y² = ( 4 × 0.225 ) × x
and, for point 6 feet away from the shore, i.e - 6 = 6 feet away from the center
we have
y² = ( 4 × 0.225 ) × 6
or
y² = 5.4
or
y = 2.32 feet (negative value is neglected as the depth cannot be negative)
Answer:
I wanna say 48 squared feet
Step-by-step explanation:
32.5 square feet
67.5 square feet
135 square feet
Answer:
67.5
Step-by-step explanation:
The temperature at the base camp on Friday evening was -6°C
The temperature at a mountain base on Thursday = -2°C
On Friday morning, the temperature was 1 degree Celsius lower than what it was on Thursday, hence:
The temperature at a mountain base on Friday morning = -2°C - 1°C = -3°C
By Friday evening, the temperature was 3 degrees Celsius lower than what it was that morning.
The temperature at a mountain base on Friday evening = -3°C -3°C = -6°C
The temperature at the base camp on Friday evening was -6°C

Answer:
-6
Step-by-step explanation:
starts at -2
then drops -1
and lastly drops -3
which leaves you at -6 degrees Celsius
Cost =16000
rate of depreciation = 35%
written down value = 2000
depreciation for one year =16000*35% = 5600
5600*2 = 11200+5600*6\12 = 2000
the car is 2.5 years old. It has been depreciated for 2 whole years and half years.
