Complete the synthetic division problem below. What is the quotient in polynomial form?

mr Goodwill [35]

A; you need to bring down the first term, 2, multiply it by -2, resulting in -4. Add -4 to 2 to get -2. Multiply -2 and get a product of 4, and add that to the third term, -4. That would give you 2, that would then be multiplied by -2 to get -4 and when added to 4, would give you a remainder of 0.

The quotient coefficients would be 2, -2, and 2, which becomes 2x² -2x + 2.

Hope this helped :)

Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒ $(1-\frac{1}{4})^5$

⇒ $(1-0.25)^5$

⇒ $(0.75)^5$

On solving the power, we get

⇒ $(0.237304)$

Now on multiplying the above value in 100, we get

⇒ $23.73$ %

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.

Answer:

$log_{b}(b^{x r})$

Step-by-step explanation:

A picture of the question is shown in the figure attached. There we can see that the step corresponding to Properties of exponents is the option:

$log_{b}(b^{x r})$

which is equivalent to

$log_{b}((b^{x})^{r})$

A building has an entry the shape of a parabolic arch 74 ft high and 28 ft wide at the base as shown below.

sergiy2304 [10]

The equation of a parabola with vertex at (h,k) is
y=a(x-h)²+k

vertex isi at (0,0)

y=a(x-0)²+0
y=a(x)²
y=ax²
find a

we see that one point is (14,-74)
x=14 and y=-74

-74=a(14²)
-74=196a
divide both sides by 196
-37/98=a

the equation is

$y= \frac{-37}{98} x^2$
