Answer:

$x(x-4)$

Step-by-step explanation:

Factor $x$ out of $x^2$

$x$ · $x$ $-4x$

Factor $x$ out of $-4x$

$x$ · $x$ + $x$ · $-4\\$

Factor $x$ out of $x$ · $x$ + $x$ · $-4\\$

$x(x-4)$

The rate of U.S. per capita sales of bottled water for the period 2007–2014 could be approximated by s(t) = 0.25t2 ? t + 29 gall

julsineya [31]

Answer:

117 gallons

Step-by-step explanation:

The expression that describes the rate of U.S. per capita sales of bottled water for the period 2007–2014 is:

$s(t) = 0.25t^2-t+29$

Since t=0 at 2007. At 2009 and 2013, t is:

$t_1=2009-2007 = 2\\t_2=2013-2007 = 6$

The definite integral of the expression from t=2 to t=6 is:

$s(t) = 0.25t^2-t+29\\\int\limits^6_2 {s(t)} \, dt= \int\limits^6_2 {(0.25t^2-t+29)} \, dt\\\int\limits^6_2 {s(t)} \,dt= (\frac{t^3}{12} -\frac{t^2}{2}+29t +c)|^6_2 \\S(6) -S(2) = (\frac{6^3}{12} -\frac{6^2}{2}+29*6 +c) - (\frac{2^3}{12} -\frac{2^2}{2}+29*2 +c)\\S(6) -S(2) = 117.333\ gallons$

Rounded to the nearest gallon, the estimated total U.S. per capita sales of bottled water from the start of 2009 to the start of 2013 is 117 gallons.

The volume of a cuboid is 176cm

IRISSAK [1]

Answer:

.08cm or 0.08cm

Step-by-step explanation:

First of all, we can see that 20mm is in millimeters, not centimeters.

If we convert the ones in centimeters to millimeters, it will result in decimals, which I want to avoid, but you could also do it that way.

There are 10 mm in 1 cm, so I multiply all of the values in cm by 10.

So now, we have that the volume is 1760mm, the length is 110mm, and the width is 20mm.

The formula for the volume of a cuboid is: $w*l*h = volume$

We have the width, length, and volume, so let's plug it in.

$20*110*h=1760$

To solve for h:

1. Multiply 20 and 100

$2200*h=1760$

2. Divide both sides by 2200

$h = 1760/2200$

3. Divide right side

h = 0.8

Keep in mind that this is in millimeters. In centimeters, it would be .08
