Which expressions are algebraically equivalent to the correct usage of the distance formula to find the distance from point A(3,

egoroff_w [7]

Answer:

(5)

Step-by-step explanation:

The given two points are:

A(3,k) and B(h,4)

Now, using the distance formula that is= $\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}$ .

In the given points, $y_{2}=4$ , $y_{1}=k$ , $x_{2}=h$ and $x_{1}=3$ , thus,

$\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}$ = $\sqrt{(4-k)^{2}+(h-3)^{2}}$

which is the required equation, hence option 5 is correct.

If a current of 12 amps produces 480 volts across a resistor then how many volts does a 15 amp produce?

LekaFEV [45]

Answer:

600 volts

Step-by-step explanation:

Given =

A = 12 ampere

V = 480 volts

A2 = 15 ampere

Solution =

R = V/I

= 480 / 12

= 40 ohms

R = V / I

V = R x I

= 40 x 15

= 600 volts

What’s a real number between the square root of 13 and the square root of 14

Pie

Real numbers can be both rational and irrational.

sqrt(13) = 3.60555

sqrt(14) = 3.74166

If you're looking for a rational number, there are lots of them to choose from. Easiest is probably 3.7 = 37/10.

An irrational number in this range might be sqrt(27/2).

Hope this helps!
