Answer:
2.a)11.355 b)0.94625
3. divide 6 by 4
4. 0.8kg, 800g
Step-by-step explanation:
To convert one measurement to another you need to set it up so that the old measurement gets cancelled out when you multiply the conversion ratio.
2a) the gallons on top and bottom get cancelled out leaving you with the measurement that you want
2b)
3)
4)
Answer:
b.
Step-by-step explanation:
We have to look at sign changes in f(x) to determine the possible positive real roots.
There is only one sign change here, between the -8x and the +4. So that means there is only 1 possible real positive root.
Now we have to look at sign changes in f(-x) to determine the possible negative real roots.
There are 3 sign changes here. That means there are either 3 negative roots or 3-2 = 1 negative root. So we have:
1 positive
3 or 1 negative
We need to pair them up now with all the possible combinations.
If we have 1 positive and 1 negative, we have to have 2 imaginary
If we have 1 positive and 3 negative, we have to have 0 imaginary
Keep in mind that the total number or roots--positive, negative, imaginary--have to add up to equal the degree of the polynomial. This is a 4th degree polynomial, so we will have 4 roots.
