Common household electric current is called alternating current because the current alternates direction within the wires. The v
Rainbow [258]

Answer:

n = 18 cycles

Step-by-step explanation:

To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:

n=ft         (1)

f: frequency of the oscillation of the current

t: time = 0.30s

The frequency is the number of cycles per second, that is, f = 60 cycles/s

You replace the values of f and t in the equation (1):

n=(60\frac{cycles}{s})(0.30s)=18\ cycles

In 0.30s the current oscillates 18 times

<u>Part 1</u>

By the inscribed angle theorem, arc PA measures 62 degrees.

<u>Part 2</u>

Angles inscribed in the same arc are congruent, so angle PRA measures 31 degrees.

<u>Part 3</u>

Diameters form semicircles, and the arc of a semicircle measures 180 degrees, so arc PAR measures 180 degrees.

<u>Part 4</u>

Subtracting arc PA from arc PAR, we get arc AR measures 118 degrees.

Complete the equation of the line through<br> (-6, -5) and (-4,-4).<br> Use exact numbers.
Nutka1998 [239]

Answer:

y = \frac{1}{2} x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 6, - 5) and (x₂, y₂ ) = (- 4, - 4)

m = \frac{-4+5}{-4+6} = \frac{1}{2}, thus

y = \frac{1}{2} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 6, - 5), then

- 5 = - 3 + c ⇒ c = - 5 + 3 = - 2

y = \frac{1}{2} x - 2 ← equation of line
