Answer:
V≈653
Step-by-step explanation:
In order to find the volume of a cylinder, you use the formula V=πr2h. In this case, the filled-in formula would be V=3.14*4*4*13. This equals 653.45. In your answer, you need to round to the nearest whole number. In this case, round down to 653. That is your answer. Hope this helps :)
Answer: B
Step-by-step explanation:
Complementary angles
Adjacent angles
Correct
Answer:
two real, unequal roots
Step-by-step explanation:
y is definied as y = 3x - 1. Substitute 3x - 1 for y in xy = 9, obtaining:
x(3x - 1) = 9. Then:
3x^2 - x - 9 = 0. In this quadratic, the coefficients are a = 3, b = -1 and c = -9.
Calculating the discriminant b^2 - 4ac, we get (-1)^2 - 4(3)(-9), or 1 + 108, or 109. Because the discriminant is positive, we have two real, unequal roots.
Answer:
OPTION B - 2
Step-by-step explanation:
What is the upper limit for the zeros of the function P(x) = 4x^4 + 8x^3 - 7x^2 - 21x - 9. Ans: 2 is an upper limit. Use synthetic division. and the remainder are all positive, 2 is an upper limit.
