Answer:
Step-by-step explanation:
8 would be the common denominator, so you would multiply the 1/2 by 4/4 to get 4/8, and if you needed to add, 4/8 + 1/8 is 5/8
T is linear transformation, since we can represent t in a marix
I= PRT
I= 1400 X 0.015 X 0.5
I= 21 X 0.5
I= 10.5
if it was a full 12 months it would be
21 x 1= 21
if it was 1/5 years it would be
21 x 1.5 = 31.5 and so on
The solution to the problem is as follows:
let y = asinx + bcosx
<span>
dy/dx = acosx - bsinx </span>
<span>
= 0 for max/min </span>
<span>
bsinx = acosx </span>
<span>
sinx/cosx = a/b </span>
<span>
tanx = a/b </span>
<span>
then the hypotenuse of the corresponding right-angled triangle is √(a^2 + b^2) </span>
<span>the max/min of y occurs when tanx = a/b </span>
<span>
then sinx = a/√(a^2 + b^2) and cosx = b/√(a^2 + b^2) </span>
<span>
y = a( a/√(a^2 + b^2)) + b( b/√(a^2 + b^2)) </span>
<span>
= (a^2 + b^2)/√(a^2 + b^2) </span>
<span>
= √(a^2 + b^2)</span>
