Answer:
Step-by-step explanation:
1. The coefficient of 2 is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.
This means that the answer is a = 2, b =1, c =5.
2. You can simply cancel out both 3s by dividing, which leaves us with 1±9.
3. The answer is c. Unfortunately, I can't explain that, it's just a well known formula.
I hope this helped!
Answer with explanation:
The equation of two curves are
y=8 sin x
y=8 cos x
The point of intersection of two curves are
→8 sin x=8 cos x
sinx = cos x
When you will look between points , 0 and ,the curve obtained is right angled triangle.
Now, rotate the curve that is right angled triangle along the line , y= -1, to obtain a shape similar or resembling with Right triangular prism.
Draw a circular disc in the right triangular prism , having radius =x,and small part on the triangle having length dx.dx varies from 0 to .
Required volume of solid obtained
=8-4√2 cubic units
