The voltage V of an audio speaker can be represented by V= 4 sqrt P , where P is the power of the speaker. An engineer wants to

Marysya12 [62]

Answer:

$Voltage=76\ volts$

Step-by-step explanation:

$Given\ V=4\sqrt{P}\\\\where\ V\ is\ voltage\ and\ P\ is\ Power.$

$Here\ power\ is\ given\\\\P=361\ watts\\\\Substitute\ P\ in\ the\ given\ equation\\\\V=4\sqrt{P}\\\\V=4\sqrt{361}\\\\V=4\sqrt{19\times 19}\\\\V=4\times 19\\\\V=76\ volts$

−3x+7y=5x+2y<br> Complete the missing value in the solution to the equation.<br> (-5,__)

Veronika [31]

Answer:

Y= -8. The complete point is (-5, -8)

Step-by-step explanation:

You have a two incognita equation.

To solve this you need another equation or some resolution number.

In this case, they tell you to complete an (X, Y) point this means they give you one of the incognitas -5.

So, use that number to replace the X and you'll have a simple one incognita equation.

$-3x+7y=5x+2y$

replace x = -5

$-3*(-5)+7y=5*(-5)+2y$

$15+7y=-25+2y$

Move the Y terms to one side and no Y terms to the other to solve

$15+25=+2y-7y$

$40=-5y$

$40/(-5)=y$

$-8=y$
