Choose the missing exponent to create a polynomial:

1 answer:

3 0

-9, because in polynomials, they term with the highest exponent is in the front (when simplified, and on a question like this it is safe to assume the polynomial is simplified,) and -9 is the only exponent that is less than both 4 and 2.

Shaneen has $30 to spend on CDs that each cost $10. She wants to calculate n, the number of CDs she can buy with her $30. Which

weqwewe [10]

Answer:

$10n \le 30$

$n \le 3$

Step-by-step explanation:

Given

$Total = \$30$

$Cost (each) = \$10$

Required

Determine the inequality

Assume she wants to buy n CDs.

If 1 CD costs $10, then n CDs costs 10n.

So, the inequality is:

$10n \le 30$

We used $\le$ because the amount she wants to spend cannot exceed 30

Divide both sides by 10, to solve for n

$n \le 3$

an astronomer wishes to measure on a photograph the distance between the image of a certain star and three star other star image

Greeley [361]

The astronomer has to choose 3 star images out of 8.This is a problem of combinations. This can be expressed as 8C3 i.e. combination of 8 objects taken 3 at a time.

$8C3= \frac{8!}{3!*5!}=56$

This means, if 8 images are nearby the astronomer will have 56 choices of the three stars.
