A battery with

Mathematics
2 answers:
drek231 [11]3 years ago
7 0

Answer:

Given,

The original percentage of battery = 20 %,

Also, Every minute that passes, an additional  5%,

So, the increment in percentage after x minutes = 5x percentage

Thus, the final battery after x minutes = ( 20 + 5x ) %

Let y represents the total percentage of battery after x minutes,

⇒ y = 20 + 5x

Which is the required function that shows the given situation.

For graphing,

y = 20 + 5x is a line having x-intercept = (-4,0)

And, y-intercept = (0,20)

Also, battery's capacity and time can not be negative,

⇒ x ≥ 0 , y ≥ 0

Y = 5x + 20

Start at (0, 20).
Then plot a point at (1, 25).

The line should be going through points (2, 30), (3, 35), (4, 40), (5, 45), etc.

For every time the x number goes up, the y number goes up 5 times for the 5%.

Can you ever use a calculator to determine if a number is rational or irrational?
timofeeve [1]
A rational number is simply a term that can be expressed as a fraction. Otherwise, that is an irrational number. So, you can use a calculator to verify if the number is rational or not.

The key characteristic of an irrational number is when it contains a long line of decimal places. For example, the term π and the Euler's number e are irrational numbers. The exact values of π and e are 3.14159 and <span>2.71828182846, respectively. In reality, those decimal places go on a long way. Particularly, </span>π<span> has a total of 2.7 trillion digits. Numbers inside radicals or roots can also be irrational numbers. For example </span>√3 is irrational because it is equal to 1.732050808. However, not all radicals are irrational. For example √15.3664 is equal to 98/25 or 3.92. That is a rational number. So, therefore, use the calculator to know the exact value of the term to properly distinguish rational from irrational.

How do you write and equation of a linear function using two points
Margaret [11]

Answer:

Step-by-step explanation:

Find the difference between the 2 points.

For example, (8, 9) (5, 3).

Compare the difference between the x's, in this case 8 and 5. The difference is 3. Do the same with the y's, 9 and 3. The difference is 6.

To find the slope, it's y/x. The slope in this situation is 6/3. Simplify. The slope is 2.

To find the y-intercept, insert the slope and one of the 2 points in the beginning into y = mx + b & solve for b.

For example, if we use the ordered pair (5, 3) the equation would look like:

3 = 2(5) + b, Solve for b.

Multiply. 3 = 10 + b

Get b by itself by adding - 10 to both sides.

-7 = b

The y-intercept is -7. So, in this case, the equation is y = 2x - 7.

Write an ordered pair for the point
aleksandr82 [10.1K]

Answer:

(0, 1)

Step-by-step explanation:

The point lies on the line x = 0.

The point lies on the line y = 1.

Where both lines intersect, that is the coordinate.

(x, y)

(0, 1)

Kipish [7]
Well, the first 16 were about 16*75=$1200 extra. The last 8 were $720 lost. Thus, the total profit is $480. He bought them with $7200, which means the profit is around 6.67%.
