Please help . I watched so many videos and still don’t understand
erastova [34]
Each cup equals 8 ounces so the 4 times 8 will eqaul 32. The next part will be multiplying 1/4 by 8/1, so as to multiply a fraction by a fraction and make it simpler. By removing the common factor of 4 from 8 and 4, you are left with 1/1 times 2/1, which ultimately equals 2 ounces. The complete answer will be 34 ounces, a whole number.

Laplace Transform f(t) = cos(t), 0 ≤ t < π 0, t ≥ π Complete the integral(s) that defines ℒ{f(t)}. ℒ{f(t)} = π dt + [infinity
tensa zangetsu [6.8K]

Answer:

L[f(t)=s/(1+s^2)]

Step-by-step explanation:

The Laplace Transform is given by the integral:

L[f(t)]=\int_0^\infty e^{-st}\ f(t)dt

by replacing f(t)=cost we get

\int_0^{\infty} e^{-st}costdt=[e^{-s(\infty)}sin(\infty)-1sin(0)]-s\int_{0}^{\infty}e^{-st}sintdt\\\\=0+s[-e^{-s(\infty)}cos(\infty)+e^{s(0)}cost(0)-s\int_0^{\infty}e^{-st}costdt]\\\\=0+s[0+1-s\int_0^{\infty}e^{-st}costdt]=s-s^2\int_0^{\infty}e^{-st}costdt\\\\(1+s^2)\int_0^{\infty}e^{-st}costdt=s\\\\\int_0^{\infty}e^{-st}costdt=\frac{s}{1+s^2}

hope this helps!!

Find the remainder when x51+x is divided by x+1
tatuchka [14]

Answer:) Let p(x) = x51 + 51 . …(i)

When we divide p(x) by x+1, we get the remainder p(-1)

On putting x= -1 in Eq. (i), we get p(-1) = (-1)51 + 51

= -1 + 51 = 50

Hence, the remainder is 50.
