Answer:
- 3.46 pounds
- 6.92 pounds
- 13.84 pounds
Step-by-step explanation:
The most accurate ratio of pounds to dollars will be found using the given numbers that have the most significant figures. Those are found on the last row of the table:
pounds/dollar = 34.60/50 = 0.692
To find the other table values, multiply the dollar amounts by this constant of proportionality. The problem statement tells you to round the result to hundredths.
$5 ⇒ 5.00 × 0.692 = 3.46 pounds
$10 ⇒ 10.00 × 0.692 = 6.92 pounds
$20 ⇒ 20.00 × 0.692 = 13.84 pounds
_____
You can also fill in the table by recognizing that $5 is one tenth of $50, so the number of pounds will be one tenth of 34.60 = 3.46. Then each of the following rows doubles the amount on the previous row.
To solve this problem, you must follow these steps:
1. Multiply the graph by -1 (That will reflect the function towards the -y axis).
2. Add 5. That will move the function upwards and you will obtain y=5 as its cut point with the y axis.
You can know the graph of a function by knowing the graph of the function "father" and applying the corresponding transformations, until turning it into the function studied.
The graph of the function f(x)=<span>|x| </span>has the shape of a cone that passes through the point (0,0).
Answer:
x=43°
Step-by-step explanation:
on b the other side is 65°
180-65=115
115-72=43°
Of course there is no way for them to be both correct, since they contradict each other.
Here is how to prove Ray incorrect. Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form.
p(x)(x - s)(x - t)(x - u)(x - v), where p(x) is some non-zero polynomial
This polynomial has a degree of at least 4. It therefore cannot be cubic.
Now prove Kelsey correct. We have already proved that there can be no more than three roots. To prove that a cubic polynomial with three roots is possible, all we have to do is offer a single example of that. This one will do.
(x - 1)(x - 2)(x - 3)
This is a cubic polynomial with three roots, and four or more roots are not possible for a cubic polynomial. Kelsey is correct.
Incidentally, if this is a roller coaster we are discussing, then a cubic polynomial is not such a good idea, either for a vertical curve or a horizontal curve.
