ANSWER

The period is

\frac{1}{60}

EXPLANATION

The equation that models the voltage, V, produced in an AC generator at time, t, in seconds is

V(t)=220 \sin(120\pi(t-1360))

The period of this function is given by:

\frac{2 \pi}{B}

Substitute the value of B to get;

=  \frac{2\pi}{120\pi}

Simplify

=  \frac{1}{60}

In the left column: how was the numerical part of the answer found (addition, subtraction )
Setler79 [48]
You can find the numerical part of the answer because it is the same on the right side.

For example:
 ¹      <<==== Regrouped
  89
+
  67
---------
146   <<=== I had to press space so I could position it.

So that also happens in subtraction, the left side can be found by doing the same steps in the right column.
For example:

67
-                    <<=== this time there was no regrouping
12
-------
55

A farmer wants to fence in a rectangular area that is 1/8 mile wide by 1/4 mile long. which of the following proportions can the
nikitadnepr [17]
1mi = 5280feet
 The first thing you should do in this case is to calculate the perimeter of the rectangle which will be given by:
 P = 2 * L + 2 * W
 Where
 L = long
 W = width
 Calculating we have:
 P = 2 * (1/4) + 2 * (1/8)
 P = 1/2 + 1/4
 P = 3/4 mi
 To calculate this distance to feet we have to use the following expression:
 (3/4) / (x) = 1/5280
 answer:
<span> B) 3/4 miles divided by x= 1 mile/5280ft

What is the solution to the equation −p − 13 = −4 /3 p + 2/3 ( 5p − 6 ) ?
jekas [21]

Answer:

The answer is p= 2 and 1/3

Step-by-step explanation:

This answer can be found using the order of operations to solve for p.

Start by distributing 2/3 by (5p-6)

add -4/3p to 10/3p equaling 6/3p or 2p

subtract 13 from both sides

-p= 2p - 7

p=2 and 1/3
