The easiest way to do this is to plug everything in the left side and see what equals 10, but you could also solve for c (which I will show you).
2c+5(c-5)=10
2c+5c-25=10
7c-25=10
7c=35
c=5

(3y^0 x^2)^6 times y^-3 zx8

timurjin [86]

Ok so some basic rules

$(x^m)(x^n)=x^{m+n}$
$(ab)^c=(a^c)(b^c)$
$(x^m)^n=x^{mn}$
$x^0=1$
$x^{-m}= \frac{1}{x^m}$

so
$[(3y^0x^2)^6][y^{-3}zx^8]$
$[(3(1)x^2)^6][y^{-3}zx^8]$
$[(3x^2)^6][y^{-3}zx^8]$
$[(3^6)((x^2)^6)][y^{-3}zx^8]$
$[(3^6)(x^{12})][y^{-3}zx^8]$
$(3^6)(x^{12})(y^{-3})(z)(x^8)$
$(3^6)(x^{12})(x^8)(y^{-3})(z)$
$(3^6)(x^{20})(\frac{1}{y^3})(z)$
$\frac{3^6x^{20}z}{y^3}$
$\frac{729x^{20}z}{y^3}$

Mike is building a rectangular dog pen the length of the pen is 20 feet greater than its with w

Temka [501]

Answer:

$f(W)=W^{2} +20W$

Step-by-step explanation:

we know that

The area of a rectangle is equal to

$A=LW$ -----> equation A

we have

$L=W+20$ -----> equation B

substitute the equation B in equation A

$A=(W+20)W$

Rewrite as a function

$f(W)=(W+20)W$

$f(W)=W^{2} +20W$

A cooling tower for a nuclear reactor is to be constructed in the shape of a hyperboloid of one sheet. The diameter at the base

zaharov [31]

Okay so the equation you need to use is (x2/a2)+(y2/b2)-(z2/c2)=1

So an equation describing the shape of the tower in the coordinates where the origin is at the center of the narrowest part of the tower would be:

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
