The mass number is the sum of protons and neutrons in the nucleus. The atomic number is the number of protons. Therefore, you can subtract the atomic number from the mass number to find the number of neutrons.

What is the inverse of y=pi/2+sin x​
Alekssandra [29.7K]

Answer:

f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})

Step-by-step explanation:

The given function is

y=\frac{\pi}{2}+\sin x

To find the inverse of this function, we interchange x and y.

x=\frac{\pi}{2}+\sin y

we now solve for y.

x-\frac{\pi}{2}=\sin y

Take the sine inverse of both sides to obtain;

\sin ^{-1}(x-\frac{\pi}{2})=y

Hence the inverse of the given function is;

f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})

where \frac{\pi}{2}-1\le x\le \frac{\pi}{2}+1

Round to the nearest whole number 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, 62
natulia [17]

The numbers 35, 2, 7, 33, 25, 70, 75, 40, 42, 12, 15, 7, 44, 20, 25, 3, 65, and 62 are all whole numbers.

  • All natural numbers and 0 are considered whole numbers. They are real numbers without fractions, decimals, or negative integers.
  • Rounding a number implies simplifying it while retaining its value close to what it was. The end output is less precise but more usable.
  • In a given base, a round number is an integer that ends with one or more "0s." So, 590 is more rounded than 592 but less rounded than 600. A round number is frequently understood in both technical and casual language to stand for a value or values close to the nominal value represented.
