Answer:

$26.50

Step-by-step explanation:

If tax is 0.72 for 12.00, divide 0.72 by 12 to find the percent.

You get 0.06, or 6% tax rate.

Lamp is $25, 6% of 25 is:

0.06 * 25 = $1.50

Add $1.50 to $25 and the price of lamp is $26.50

The polynomial of degree 3, P(x), has a root of multiplicity 2 at x=5 and a root of multiplicity 1 at x=−5.
satela [25.4K]

Answer:

P(x) = -0.7(x-5)^{2}(x+5)

Step-by-step explanation:

Root multiplicity of 2 means the root is repeated 2 times. Root multiplicity of 1 means root is repeated only once.

A polynomial of degree 3 means the largest exponent of x is 3.

Here, the polynomial P(x) has root 5 with multiplicity 2 and -5 with multiplicity 1.

So, P(x) = a(x-5)^{2}(x+5)

Where, a is a constant.

Now, it's given that the y intercept is -87.5. Therefore, value of x at y intercept is 0.

We obtain a by plugging in -87.5 for P(x) and 0 for x.

-87.5=a(0-5)^{2}(0+5)

-87.5=a(25\times5)\\ a=-\frac{87.5}{125}=-0.7

Therefore, the polynomial P(x) is given as:

P(x) =-0.7(x-5)^{2}(x+5)

Oceanside Bike Rental Shop charges 12 dollars plus 7 dollars an hour for renting a bike. Sandy paid 40
alexgriva [62]

x = # of hours the bike was rented.

$40 = $12 + $7x

Subtract $12 from both sides.

$28 = $7x

Divide both sides by $7

4 = x

Sandy rented the bike for 4 hours.
