Answer:
Step-by-step explanation:
The least number of degree is 3 and the third root should be (4 - i) to make polynomial rational.
<u>The polynomial is:</u>
- (x - 3)(x - (4 + i))(x - (4 + i)) =
- (x - 3)(x² -x(4 + i + 4 - i) + (4 + i)(4 - i)) =
- (x - 3)(x² - 8x + 16 - (-1)) =
- (x - 3)(x² - 8x + 17) =
- x³ - 8x² + 17x - 3x² + 24x - 51 =
- x³ - 11x² + 41x - 51
Answer: x = 16
Step-by-step explanation:
24 + 2 + 4x = 90
26 + 4x = 90
4x = 64
x = 16
Answer:
115.2 inches
Step-by-step explanation:
What we must do is calculate the ratio between the real version and the version to be imitated, in this case the ice cream cone.
To calculate the ratio, we will do it through the diameter:
48 / 2.5 = 19.2
So the ratio is 19.2: 1
Which means that one inch of the ice cream cone represents 19.2 inches in the real version.
Therefore, in the case of height it would be:
6 * 19.2 = 115.2
Therefore, the height should be 115.2 inches.
Answer:
Step-by-step explanation:
Look what happens if you do the multiplication of P(x):
P(x) = x^3 - 9x
This is a variation of the basic cubing function y = x^3.
The graph begins in QIII and ends in QI; in other words, if you go left the graph drops; if you go right, the graph rises (without limit, in both cases).
