Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to
print two random integers between (and including) 0 and 9. End with a newline. Ex: 5 7 Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again. (Notes)

Explanation:
No number is really ever random. It all has a seed, which is an initial value for the 'random' number to be generated. The rand() function uses an equation to generate its value, and all its 'random' value depend on the first number you plug in into your equation. The initial number you plug into your equation is what srand() do.
If you just call rand() alone without calling srand() then the generated numbers will automatically use srand(1) as a default seed. Using the same srand() value will always yield the same sequence of numbers.
To get a number between 0 and 9, take the modulus of it with 10 because modulus give you the remainder, so the number rand()%10 will never be equal to 10 or greater.

By applying the concepts of differential and derivative, the differential for y = (1/x) · sin 2x and evaluated at x = π and dx = 0.25 is equal to 1/2π.
<h3>How to determine the differential of a one-variable function</h3>
Differentials represent the <em>instantaneous</em> change of a variable. As the given function has only one variable, the differential can be found by using <em>ordinary</em> derivatives. It follows:
dy = y'(x) · dx (1)
If we know that y = (1/x) · sin 2x, x = π and dx = 0.25, then the differential to be evaluated is:

Answer:
fracture will occur as the value is less than E/10 (= 22.5)
Explanation:
If the maximum strength at tip Is greater than theoretical fracture strength value then fracture will occur and if the maximum strength is lower than theoretical fracture strength then no fracture will occur.
= 15 GPa
fracture will occur as the value is less than E/10 = 22.5
