Answer:

C. 2x² - 2x + 2

General Formulas and Concepts:

Algebra II

Long Division and Synthetic Division

Step-by-step explanation:

Step 1: Define

Function f(x) = 2x³ + 2x² - 2x + 4

Divisor Root (x + 2)

Step 2: Synthetic Division

See Attachment.

If the Remainder equals 0, then the Divisor Root is indeed an actual root of the function polynomial. If the Remainder does not equal 0, the Divisor Root is not an actual root of the function polynomial.

A container is being filled with water at a steady rate. The graph shows how the volume of water in the container varies with th

Mkey [24]

Answer: a. $v=\dfrac{2}{3}t$ and b. $t=\dfrac{3}{2}v$ .

Step-by-step explanation:

Let as consider,

Volume (in gallons) of water in the container = v

The number of minutes = t

(a)

From the given graph it is clear that the line passing through the points (0,0) and (3,2). So, the equation of line is

$v-v_1=\dfrac{v_2-v_1}{t_2-t_1}(t-t_1)$

$v-0=\dfrac{2-0}{3-0}(t-0)$

$v=\dfrac{2}{3}t$

Therefore, the required formula is $v=\dfrac{2}{3}t$ .

(b)

We have,

$v=\dfrac{2}{3}t$

Multiply both sides by 3/2.

$v\times \dfrac{3}{2}=\dfrac{2}{3}t\times \dfrac{3}{2}$

$\dfrac{3}{2}v=t$

$t=\dfrac{3}{2}v$

Therefore, the required formula is $t=\dfrac{3}{2}v$ .

These two maps show the same area at two different scales. Colombus is not on Map A. Scale on Map A, 1 cm = 40 mi. Map B does no

dimaraw [331]

Answer:

144 miles

Step-by-step explanation:

The scale of map B is (3.4 cm)/(6.8 cm) = 1/2 that of map A. Then the distance (d) between the cities is ...

(1.8 cm)/d = (1/2)·(1 cm)/(40 mi)

Multiplying by d·80 mi, we get ...

144 mi·cm = d cm

Dividing by cm, we have ...

144 mi = d

The distance from Gladville to Columbus is 144 miles.
