Let p represent her present test point total, and t represent the necessary average on the next two tests.
.. p +2t ≥ 450 . . . . she wants an A grade after the next two tests
.. t ≥ (450 -p)/2 . . . her required average on the next two tests
Answer:
280 miles
Step-by-step explanation:
in one hour, you would travel 70 miles because you are going at the speed of 70mph
so to find out how far you go in 4 hours you would multiply 70(mph)×4(hrs) which would be?
280 miles
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
