48 is 80% of 60
48 of 60 can be written as 48/60
Multiply both the numerator and the denominator by 100
48/60 · 100/100 = 80/100 = .8 = 80%
If you are using a calculator, simply enter 48 ÷ 60 · 100 which will give you 80 as the answer.
Two lines intersecting at a right angle would be perpendicular. Parallel lines do not cross or touch each other, and rats don’t form right angles. Perpendicular lines are horizontal and vertical crossing together to form a right angle.
Hope this helps!
If I understand this correctly I would say $105. Hope this helps. :)
The solution to the given differential equation is yp=−14xcos(2x)
The characteristic equation for this differential equation is:
P(s)=s2+4
The roots of the characteristic equation are:
s=±2i
Therefore, the homogeneous solution is:
yh=c1sin(2x)+c2cos(2x)
Notice that the forcing function has the same angular frequency as the homogeneous solution. In this case, we have resonance. The particular solution will have the form:
yp=Axsin(2x)+Bxcos(2x)
If you take the second derivative of the equation above for yp , and then substitute that result, y′′p , along with equation for yp above, into the left-hand side of the original differential equation, and then simultaneously solve for the values of A and B that make the left-hand side of the differential equation equal to the forcing function on the right-hand side, sin(2x) , you will find:
A=0
B=−14
Therefore,
yp=−14xcos(2x)

Answer:
205
Step-by-step explanation:
Given
N(t) = 100 + 15t is the equation of the relation.
We're asked to find N(7)
Taking a look at the question again and putting it side by side the equation
N(t)
N(7)
We can deduce that t = 7, and as such, solve for it in the equation given
N(7) = 100 + 15(7)
N(7) = 100 + 105
N(7) = 205
Therefore, the number of unread mails after 7 days will be 205
