E=VIT how would I isolate the “V” variable

Zigmanuir [339]

Answer:

$V =\frac{E}{IT}$

Step-by-step explanation:

You can isolate the "V" variable by dividing by IT on both sides:

$\frac{E}{IT} =\frac{VIT}{IT}$

On the left, the IT from the top and bottom cancel, leaving you with just V:

$V =\frac{E}{IT}$

State the amplitude, period, phase shift, and vertical shift of the function h(t)= cos (t+1)

oksano4ka [1.4K]

Answer:

Option b.

Step-by-step explanation:

We can easily solve this problem by using a graphing calculator or plotting tool.

The function is

h(t) = cos (t +1)

Please, see attached picture below.

By looking at the picture, we can tell that the amplitude is equal to 1

The function has a period of T = 2π

We can see there is no vertical shift.

It has a phase shift of +1. (Which moves the graph to the left)

Option b.

A company that teaches self-improvement seminars is holding one of its seminars in Middletown. The company pays a flat fee of $1

Nutka1998 [239]

Answers:

To reach the breakeven point, how many attendees will that take? <u> 117 </u>

What will be the company's total expenses and revenues? <u> $1755 for each </u>

=============================================================

Explanation:

x = number of attendees

C(x) = cost function for the company

C(x) = 14x+117

This is because the company pays $14 per person, so x of them accounts for 14x dollars. Then we add on the flat fee of $117 to get 14x+117 dollars overall.

In contrast, the revenue is

R(x) = 15x

because each attendee brings in $15 for the company

The breakeven point is when the cost and revenue are the same. This produces a profit of $0.

R(x) = C(x)

15x = 14x+117

15x-14x = 117

x = 117

If 117 people attend the seminar, then the company breaks even.

To check this, we'll compute the cost and revenue

C(x) = 14x+117

C(117) = 14*117+117

C(117) = 1755

R(x) = 15x

R(117) = 15*117

R(117) = 1755

The cost and revenue is $1755 for each. Because we get the same value, this confirms the correct x value.

Since 117 people is the breakeven point, the company should aim for an attendee count above this, so they can get a positive profit. At some point, there is a max capacity so x can't go up forever.
