Maru [420]

Answer:

The installation fee is $150

Step-by-step explanation:

Ok so we need to see how much of the $210 is the installation fee. So first were going to multiply 5 by 12 which equals 60. So now were going to subtract that from the $210 so that gives us...

$210-$60=$150

What values of b satisfy 3(2b + 3)2 = 36?

KiRa [710]

the correct question is

What values of b satisfy 3(2b+3)^2 = 36

we have

$3(2b+3)^2 = 36$

Divide both sides by $3$

$(2b+3)^2 = 12$

take the square root of both sides

$( 2b+3)} =(+ /-) \sqrt{12} \\ 2b=(+ /-) \sqrt{12}-3$

$b1=\frac{\sqrt{12}}{2} -\frac{3}{2}$

$b1=\sqrt{3} -\frac{3}{2}$

$b2=\frac{-\sqrt{12}}{2} -\frac{3}{2}$

$b2=-\sqrt{3} -\frac{3}{2}$

therefore

the answer is

the values of b are

$b1=\sqrt{3} -\frac{3}{2}$

$b2=-\sqrt{3} -\frac{3}{2}$

You earn $9 per hour babysitting. This is $2 more than what you earned per hour last year. What did you earn last year?

slamgirl [31]

$7 is the correct answer for *per hour*, as 9-2=7. Notice how it says how much did you earn last year, implying total earned. How many hours did you work last year?

Consider f and c below. f(x, y, z) = (y2z + 2xz2)i + 2xyzj + (xy2 + 2x2z)k,

qaws [65]

$\dfrac{\partial f}{\partial x}=y^2z+2xz^2$
$f(x,y,z)=xy^2z+x^2z^2+g(y,z)$

$\dfrac{\partial f}{\partial y}=2xyz+\dfrac{\partial g}{\partial y}=2xyz$
$\dfrac{\partial g}{\partial y}=0\implies g(y,z)=h(z)$

$\dfrac{\partial f}{\partial z}=xy^2+2x^2z+\dfrac{\mathrm dh}{\mathrm dz}=xy^2+2x^2z$
$\dfrac{\mathrm dh}{\mathrm dz}=0\implies h(z)=0$

$\implies f(x,y,z)=xy^2z+x^2z^2+C$
