Answer:
The diameter decreases at a rate of 0.053 cm/min.
Step-by-step explanation:
Surface area of an snowball
The surface area of an snowball has the following equation:
In which d is the diameter.
Implicit differentiation:
To solve this question, we differentiate the equation for the surface area implictly, in function of t. So
Surface area decreases at a rate of 3 cm2/min
This means that 
Tind the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm.
This is 
when 
. So
The diameter decreases at a rate of 0.053 cm/min.

Answer:
(c) 144 m²
Step-by-step explanation:
The surface area can be calculated from ...
SA = 2(LW +H(L+W))
SA = 2((6 m)(6 m) +(3 m)(6 m +6 m))
= 2(36 m² +(3 m)(12 m)) = 2(36 m² +36 m²) = 2(72 m²)
SA = 144 m²

<em>Additional comment</em>
The units of area are square meters (m²). The units of volume are cubic meters (m³).

Answer:
Step-by-step explanation:
Given that interest rates are as follows:
Let P be 100 dollars for each.
A) 3.15% compounded monthly.
Hence amount = 
Final amount = 103.20 dollars
B) 2.25% compounded quarterly
Final amt. = 
=102.27
C) 2.05% compounded daily
Amount = 
=102.07
Obviously A is the best deal.
Answer:
4527.29
Step-by-step explanation:
P=3200(1+0.07/4)^4(5)
Formula
P=A(1+R/N) ^nt
A= amount=$3200
R=rate7% convert to decimal 0.07
T=time 5 years
N= quarterly(4)
Yearly would be 12
Daily 365 and
continuously would be a different formula
