The answer would be (x,y) —> (x-1,y). the reasoning being that all of the points on the x axis move to the left by one unit, and all points on the y axis stay the same.

Which expression is equivalent to StartFraction 3 x Superscript negative 6 Baseline y Superscript negative 3 Baseline Over 15 x
arsen [322]

Answer:

<h3>The correct expression is 1 Over 5 x Superscript minus 8 Baseline y Superscript minus 13 Baseline EndFraction</h3>

Step-by-step explanation:

Given the expression \frac{3x^{-6}y^{-3} }{15x^{2}y^{10}  }for x ≠ 0, y ≠ 0 to get the equivalent expression we will have to simplify the given expression.

\frac{3x^{-6}y^{-3} }{15x^{2}y^{10}  }\\= \frac{3}{15} x^{-6-2}y^{-3-10}\\ = \frac{3}{15}x^{-8}y^{-13}  \\ =\frac{1}{5}x^{-8}y^{-13}  \\

The correct expression is 1 Over 5 x Superscript minus 8 Baseline y Superscript minus 13 Baseline EndFraction

Which of the following functions gives the radius, r(v), of a conical artifact that is 20 inches tall as a function of its volum
irinina [24]
<h3><u>Radius as function of volume is:</u></h3>

r(v) = \sqrt{\frac{3v}{20 \pi }}\ inches

<em><u>Solution:</u></em>

<em><u>The volume of cone is given as</u></em>:

v = \frac{1}{3}\pi r^{2} h

Where,

r is the radius

h is the height

From given,

height = 20 inches

From formula,

v = \frac{1}{3}\pi r^{2} h

Rearrange , so that r is alone in left side of equation

3v = \pi r^2 h\\\\\pi r^2 h = 3v\\\\r^2 = \frac{3v}{\pi h}\\\\Take\ square\ root\ on\ both\ sides\\\\r = \sqrt{\frac{3v}{\pi h}}

Substitute h = 20

r = \sqrt{\frac{3v}{20 \pi }}

Thus, radius as function of volume is:

r(v) = \sqrt{\frac{3v}{20 \pi }}\ inches

Answer:

Angle PQW is equal to 35 degrees

Step-by-step explanation:

Angle PQW = 36x - 1

Angle WQR = 134x

Angle PQR = 169 degrees

To find angle PQW, Set Angles PQR and WQR to PQW. The equation should look like this:

PQR - WQR = PQW

Substitute in the values

169 - 134x = 36x - 1

Now add 134x to both sides and add 1 to both sides.

170 = 170x

Now divide 170 from both sides

x = 1

Plug x into angle PQW

36(1) - 1 = 35
