Answer:
<em>Thang will pay $1620 interest</em>
Step-by-step explanation:
<u>Simple Interest</u>
Definition: Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Thang borrowed P=$6000 from his local bank. The loan was for t=3 years at a simple interest rate of r=9% = 0.09. The interest is calculated as:
I = 6000*0.09*3
I = 1620
Thang will pay $1620 interest
Answer:
103 ft
Step-by-step explanation: First, you find the area of the garage door as a whole (112 ft). Then, you find the area of each the three windows and add them together (their total area together is 9 ft). Lastly, you subtract this sum from the area of the whole door and the answer that you will get is 103 ft. Hope this helps :)
The surface is parameterized by
and the normal to the surface is given by the cross product of the partial derivatives of 
:
It looks like you're given
Then the normal vector is
Now, the point (2, 2, 0) corresponds to u and v such that
and solving gives 
, so the normal vector at the point we care about is
Then the equation of the tangent plane is
