Answer:
Step-by-step explanation:
Given that:
The surface area (S.A)
Hence the S.A is of form z = f(x,y)
Then the S.A can be represented with the equation
where :
D = cylinder
In polar co-ordinates:
D = {(r, θ): 0≤ r ≤ 1, 0 ≤ θ ≤ 2π)
Similarly, and
Therefore;
Answer:
7 x > 4 x + 100
7 x - 4 x > 100
3 x > 100
x > 100 : 3
x > 33.33
Answer: they have to sell 34 pizzas to make a profit.
Step-by-step explanation:
(2x + 10)(x - 9)
2x(x - 9) + 10(x - 9)
2x(x) - 2x(9) + 10(x) - 10(9)
2x² - 18x + 10x - 90
2x² - 8x - 90
(1,4) you go right 1 time, and than go up 4.
Answer:
NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season
