Answer:
y(t) = 391 - 30t
Step-by-step explanation:
The weekly difference is 391-361 = 30
y(t) = 391 - 30t.
With t being the number of weeks.
Answer:
B. the more inelastic is the demand for the final product.
Explanation:
Inelastic demand occurs when demand rises by a lower percentage as compared to the percentage of the price drop.
Take for instance, if price drops by 10% and then demand only rises by 4%.
Now, the derived demand curve for a product component will be more inelastic when there's more rises by lower percentages of the final product than price drop. The more inelastic the demand for a product is, the more inelastic the demand derive curve will be.

Given that a polynomial function P(x) has rational coefficients.
Two roots are already given which are i and 7+8i,
Now we have to find two additional roots of P(x)=0
Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.
conjugate of a+bi is given by a-bi
So using that logic, conjugate of i is i
also conjugate of 7+8i is 7-8i
Hence final answer for the remaining roots are (-i) and (7-8i).
