Which equation can be simplified to find the inverse of y = 5x² + 10?

notsponge [240]

Answer:

See below

Step-by-step explanation:

Here is how to start....you didn't include the equations in question, so I do not know what the answer may be

solve for x

y-10 = 5 x^2 divide thru by 5

(y-10)/5 = x^2 'sqrt' both sides

± sqrt( (y-10) / 5 = x change x's and y's

± sqrt ((x-10)/5) = y

The electric potential in a circuit is given by

shtirl [24]

We are given with the equationL
V(t) = 320 e^(-3.1t)
At V = 200
200 = 320 e^(-3.1t)
t = 0.15 s

100 = 320 e^(-3.1t)
t = 0.36 s

It takes 0.36 - 0.15 = 0.21 s for the voltage to drop from 200 to 100 volts.

Find the distance between each pair of points

densk [106]

Answer:

Use Distance Formula

Step-by-step explanation:

You can find the distance between two points by using the distance formula which by definition is $\sqrt{(x_2-x_1 )^2+(y_2-y_1)^2 }$

For example take question 3. Plug your point values in to find the distance

Point 1 is (-1, 8)

Point 2 is (-3, -2)

You equation would look like:

$\sqrt{(-3-(-1))^2+(-2-8)^2}$

This simplifies to $\sqrt{(-2)^2+(-10)^2}$

= $\sqrt{4+100}$

= $\sqrt{104}$

= $\sqrt{2(2)(26)}$

= $2\sqrt{26}$

That is the distance between the points (-1, 8) and (-3, -2)
