The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27/125 of a volt and it has

been reduced three times. Write the voltage in exponential form. What was the original voltage in the circuit?

The <em>correct answer</em> is:


x³ = 27/125; and

x = 3/5.


Explanation:


Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us

x³.


The current voltage is 27/125; this gives us the equation

x³ = 27/125.


To solve this, take the cubed root of both sides:

∛(x³) = ∛(27/125)

x = (∛27)/(∛125)

x = (∛(3*3*3))/(∛(5*5*5))

x = 3/5

Exponential form: F(x)= 3/125^x+1
Original voltage: 3/125 of a volt

Answer: top right

Step-by-step explanation: in order to seperate p, we need to multiply each side by 6, as this will make the right side just p. Then, since we mutiplied by 6 on the right side, we multiply by 6 on the left side too, so we get 5.5*6

Identify the equation in slope-intercept form for the line with the given slope that contains the given point. Slope =2; (1,4)
Elina [12.6K]

Slope-intercept form: y=mx+b, with m being the slope and b being the y-intercept. First, plug in the given slope into the slope form:

y=2x+b

Now, given the coordinates (1,4), you can plug the coordinates into the equation for x and y respectively, to solve for b (the y-intercept).

4=2(1)+b

4=2+b

Subtract 2 from both sides.

2=b

The y-intercept is 2.

Now, plug that into the equation:

y=2x+2

The answer is y=2x+2.

I hope this helps :)

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
mixas84 [53]

Answer:

<h2><em>D. (-7, 3)</em></h2>

Step-by-step explanation:

The standard form of a point slope equation of a line is expressed as shown;

y-y₀ = m(x-x₀) where;

m is the slope of the line

(x₀, y₀) is the coordinate of the point that lies in the line.

Comparing the standard equation given with the equation in question

y - 3 = 4(x + 7) to get the point on the line we will have;

y₀  = 3 and -x₀ = 7

for -x₀ = 7;

multiply both sides with a minus sign

-(-x₀) = -7

x₀ = -7

<em>Hence the coordinate of the point required (x₀, y₀) is (-7, 3).</em>

The relantionship between the number of $12 dvds you buy and the total cost
Elodia [21]
Y = kx

Y is the total cost

The number of dvds is x

The cost of each one ($12) is k

y = $12x

Or instead of Y you can but T for total cost

t = $12x
