1/5 of a foot
Simply subtract the height of Pancho’s sandcastle (3/5 of a foot) minus the height of his sister’s sandcastle (2/5 of a foot) to find a difference of 1/5 of a foot, meaning Pancho’s sandcastle was 1/5 of a foot taller than his sister’s sandcastle.
Answer:
The other rational number is
.
Step-by-step explanation:
First rational number is 
Let other rational number is 
The product of two rational numbers is 
According to question,

Multiplying both sides by (-3/2) such that,

So, the other rational number is
.
We have been given two functions
and
. We are asked to find
.
We will use composite function property
to solve our given problem.
Now we will combine like terms as:


Therefore, the value of
would be
.
<span>sin A cos B=1/2[sin(A-B)+sin(A+B)]
sin(at)*cos(2at)=1/2[sin(3at)-sin(at)]</span>
