Answer:
f(x) = is the required polynomial.
Step-by-step explanation:
Given the zeroes (roots) of the polynomial are and
.
We know that complex roots occur in conjugate pairs.
So, this means that and
would also be the roots of the polynomial.
If are to be the roots of the polynomial then the polynomial should have been:
.
Now, to determine the polynomial for which would be the roots.
Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.
⇒
⇒
The required polynomial would be the product of all the above polynomials.
Multiply this to get the required equation.
⇒
∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.
The model of the granola bars is an illustration of <em>ratios and proportions</em>.
The model that shows the total serving is model A
The given parameters are:
So, the number of servings in both bars is:
Substitute 2 for Bars and 2/5 for Servings
Express as multiplication
The total number of servings is 5
The model that shows a total serving of 5 is model A (see attachment)
