Find a polynomial function of degree 4 with − 2 as a zero of multiplicity 3 and 0 as a zero of multiplicity 1.

1 answer:

3 0

Degree 4 means you'll have x^4 as your leading term. Multiplicity of 3 means you have the same factor 3 times. So if x = -2, then (x + 2) = 0, so (x + 2) is used 3 times. FOIL that out 3 times and you get x^3 + 6x^2 + 12x + 8. Now multiply by (x + 0) to get a 4th degree polynomial of x^4 + 6x^3 + 12x^2 + 8x. There!

A fitness club has two options, one for members and one for nonmembers. Members pay a one-time registration fee of $12 plus $8 p

Liula [17]

Answer:

See below.

Step-by-step explanation:

Let's look at the cost for members (C1) first. Let x be the number of visits.

C1(x) = 12 + 8x

For non-members (C2), we can do the same.

C2(x) = 10x

You can graph these two equations.

x C1 C2

0 12 0

1 20 10

2 28 20

3 36 30

4 44 40

5 52 50

6 60 60

7 68 70

Let's make the two equations equal, to find out where the benefit is the same.

12 + 8x = 10x

2x = 12

x = 6

Up to 5 visits, the non-member cost is better. At 6 visits, there's the same price. For more than 6 visits, the member cost is better.

ser-zykov [4K]

The sale price S (in dollars) of an item is given by the formula

S=L−rL , where L is the list price (in dollars) and r is the discount rate.

Since, S = L -rL

rL = L -S

r = $\frac{L-S}{L}$

r = $1-\frac{S}{L}$

Since, the listed price of the shirt is $30, we have to find the discount rate.

Therefore, r = $1-\frac{S}{30}$ is the discount rate.
