Answer: The refrigerator cost in this month is $4.5 approximately.

Step-by-step explanation:

Since we have given that

Amount of watt of electric power = 320 W

Number of days = 30

Unit cost of electricity = $0.13/Kwh

Hold factor = \dfrac{1}{4}

Number of hours in a month = 24

So, the refrigerator cost in this month would be

0.13\times 0.32\times \dfrac{1}{4}\times 30\times 24\\\\=\$7.488

Hence, the refrigerator cost in this month is $4.5 approximately.

Answer:

The answer is 40

Step-by-step explanation:

The reason for this is because. . .

(-1,-4) , (3,6)

so you have count from -1 to 3 and u will get 4, because if you can put (-1,-4) and (3,6) on a graph. If you did that then u must count horizantolly from -1 to 3 since they are on the x-axis. In the end you will get 4 since 3 minus -1 is 4. Also if your counting horizantally then that's ur width.

width = 4

To find the length, it is very simple. Subrtract 6 from -4 and you will get 10. And since the y-axis is being counted vertically, that is your length.

length = 10

To find the area, u have to do width times length so in this case you have to do 4 time 10 and you will get 40.

area = 40

Given that -6,-6 is on the graph of f x find the corresponding point for the function f(3/4x)
Liono4ka [1.6K]

Answer:

The corresponding point is <em>(-8, -6).</em>

Step-by-step explanation:

Given that

(-6,-6) lies on the graph of f(x)

A function is represented in the form:

y = f(x)

i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.

f(-6) = -6

Now, we have to find the corresponding point on f(\frac{3}{4}x).

We know the value of f(-6)

Let us find the value of x where \frac{3}{4}x becomes equal to -6

\dfrac{3}{4}x=-6\\\Rightarrow 3x=-24\\ \Rightarrow x =-8

So, let us put value of x = -8 in f(\frac{3}{4}x):

f(\frac{3}{4}\times (-8))\\\Rightarrow f(3\times (-2))\\\Rightarrow  f(-6) = -6(as per given statement)

So, the corresponding point is <em>(-8, -6).</em>
