$V=hb$

$h= \frac V b$

$h = \dfrac{ x^3 - 3x^2 + 5x - 3}{x^2 -2}$

Expressing that as a quotient and remainder,

$h =x - 3 = \dfrac{ 7 x - 9} { x^2 - 2}$

First choice.

Anna is draining water out of a 50 gallon rain barrel. The graph shows the relationship between time in minutes and the gallons

tatiyna

Answer:

6 < x ≤ 20

Step-by-step explanation:

First, let's use the points (0, 50) and (20, 0) to find the equation of the line.

m = Δy / Δx

m = (0 − 50) / (20 − 0)

m = -2.5

y = -2.5x + 50

Now find the time when y = 35.

35 = -2.5x + 50

-15 = -2.5x

x = 6

So there is less than 35 gallons in the barrel when 6 < x ≤ 20.

Which equation is a point slope form equation for line AB ?

Jobisdone [24]

For this case we have that by definition, the equation of a line of the point-slope form is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0}):$ It is a point through which the line passes

To find the slope, we need two points through which the line passes, observing the image we have:

$(x_ {1}, y_ {1}): (1,6)\\(x_ {2}, y_ {2}): (5, -2)\\m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-2-6} {5-1} = \frac {-8} {4} = -2$

Thus, the equation is of the form:

$y-y_ {0} = - 2 (x-x_ {0})$

We choose a point:

$(x_{0}, y_ {0}) :( 5, -2)$

Finally, the equation is:

$y - (- 2) = - 2 (x-5)\\y + 2 = -2 (x-5)$

Answer:

$y + 2 = -2 (x-5)$

You know that 15% of a number n is 12. How can you use this to find 30% of n? 45% of n? Explain.

Keith_Richards [23]

30% is 24
45% is 36
take 15% and multiply it by however much it takes to make the percentage than multiply that by 12
