A closed container has 2.04 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10−24 grams. Which of the following shows

and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
0.34 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068 ⋅ 10−1
0.37 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71 ⋅ 10−1
3.41 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068
3.71 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71

write the slope intercept equation. the graph of f passes through (-6,4) and is perpendicular to the line that has an x-intercep
Nimfa-mama [501]

Answer:

y = -\frac{1}{3} x + 2

Step-by-step explanation:

The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:

Slope(s) = Change in y ÷ change in x

s = \frac{0 - -6}{2 - 0} = 3

The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = -\frac{1}{3}

Reason: The product of slopes of lines perpendicular to each other have to be -1

So the slope of the perpendicular line that passes through (-6,4) is -\frac{1}{3}

As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x

Taking another point (x,y) on the line,

-\frac{1}{3} = \frac{y - 4}{x - -6}

-\frac{1}{3} = \frac{y - 4}{x + 6}

y - 4 = -\frac{1}{3}x - 2

y = -\frac{1}{3}x + 2

Please answer with explanation of how you got the answer !!
Irina18 [472]

Answer:

−24

Step-by-step explanation:

Since there is only one negative, this means when all the values are multiplied together the product will be negative. Just multiply all three together to get −24.

(3)(−4)(2)

(−12)(2)

−24

It doesn't matter which order you multiply in in this case.
