Answer:

Absolute value is the distance from numbers on a number line. The absolute value of -7 is 7 b/c it is 7 units from 0. The absolute value of 5 is 5 b/c it is 5 units from 0.

A negative number is a number that is negative. On a horizontal number line negative numbers are to the left.

A positive number is a number that is positive. On a horizontal number line positive numbers are to the right.

I don't understand the last paragraph though. Hope this helped :D

What is 5.8x10^6 seconds in minutes
Troyanec [42]
Let x be the number of minutes of 5.8*10^6 seconds.
Each minute is made of 60 seconds. Let's then use the rule of three:

60 seconds --> 1 minute
5.8*10^6 --> x minutes

x = (5.8*10^6)*1 / 60
x ≈ 96,666.66 minutes.

So 5.8*10^6 seconds is about 96,666.66 minutes.

Hope this Helps! :)

R of breaths of all people in asia in 2016? Expressing your answer in scinentific notation in the form a *10^(b) what are the va
Andrew [12]

Answer:

a = 3.7464

b = 16

Step-by-step explanation:

Given

See attachment for complete question

Required

Express the answer in a * 10^b

From the question, we have:

People = 4.46 * 10^9

Breath = 8.4 * 10^6 breath/person in a year

The number of breath is calculated by:

Overall = People * Breath

So, we have:

Overall = 4.46 * 10^9 * 8.4 * 10^6

Reorder

Overall = 4.46  * 8.4* 10^9 * 10^6

Overall = 37.464* 10^{9+6}

Overall = 37.464* 10^{15}

Using scientific notation a * 10^b;

The value (a) must be in the following interval 0 \le a \le 1

So, we have:

Overall = 3.7464 * 10 * 10^{15

Overall = 3.7464 * 10^{16

By comparing the above with: a * 10^b

a = 3.7464

b = 16

Determine the intercepts of the line. yy y y -intercept: (\Big( ( left parenthesis ,, , comma )\Big) ) right parenthesis xx x x
BlackZzzverrR [31]

Question:

Give all the x and y intercept of the function

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30}

Answer:

The x intercepts are x = 5 and x = -4

The y intercept is at y = -2

Step-by-step explanation:

Factorizing the numerator of the expression we find the x intercepts as follows;

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30} =\frac{3(x-5)(x+4)}{2x^3 + 2x^2-34x+30}

Therefore, the x intercept are

x = 5 and x = -4

To find the y intercept, we put x = 0 to get y = -2

Therefore, the y intercept is at y = -2

Factorizing the denominator we find the values for which the equation is undefined

2·x³ + 2·x² - 34·x + 30 = 2·(x-1)·(x-3)·(x+5) which gives

x = 1, 3 and -5.
