Answer:
Equation: y(1.09)^x
After 10 years there will be about 12 squirrels.
Step-by-step explanation:
y(1.09)^x
=5(1.09)^10
=(approx.) 12 squirrels
Answer:
Diameter of the circle is twice it's radius D=2r.
Circumference of the circle is 2πr.
According to the above problem,
<u>2π(radius)</u>=20 inches
2(radius)=20/π=20/3.14
Diameter=<u>6.37 inches</u>
<h3><u>6.37 inches</u> is the right answer.</h3>
Let x be the height of the box and y be the length of one side of the base then:-
V = xy^2 = 108
x = 108/y^2
Surface area = y^2 + 4xy
S = y^2 + 4y* 108/y^2
S = y^2 + 432/y
Finding the derivative:-
dS/dy = 2y - 432/y^2 = 0
2y^3 = 432
y^3 = 216
y = 6
Check if this gives a minimum value:-
second derivative = 2 + 864/y^3 which is positive so minimum.
V = xy^2 = 108
36y = 108
y = 3
Answer :- dimensions of the box is 3*6*6 metres
