1 answer:

4 0

Answer: n = -rt/10 + 1/10

Explanation: isolate the variable by dividing each side with the factors that don’t contain n, then isolate n to get this answer.

Hope this helps!

A conservative estimate of the number of stars in the universe is 6 x 10^22. The average human can see about 3,000 stars at nigh

Ilia_Sergeevich [38]

$2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

<h3><u>Solution:</u></h3>

Given that, conservative estimate of the number of stars in the universe is $6 \times 10^{22}$

The average human can see about 3,000 stars at night with only their eyes

To find: Number of times more stars are there in the universe, compared to the stars a human can see

Let "x" be the number of times more stars are there in the universe, compared to the stars a human can see

Then from given statement,

$\text{Stars in universe} = x \times \text{ number of stars human can see}$

<em><u>Substituting given values we get,</u></em>

$6 \times 10^{22} = x \times 3000\\\\x = \frac{6 \times 10^{22}}{3000}\\\\x = \frac{6 \times 10^{22}}{3 \times 10^3}\\\\x = 2 \times 10^{22-3}\\\\x = 2 \times 10^{19}$

Thus $2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

Find at least three ordered pairs for slope equation y=2/5x-1

Westkost [7]

Subsitute values for x and evaluate to get values for y
when x=5, y=1
when x=0, y=-1
when x=-5, y=-3

remember, ordered pairs are in (x,y) form

so 3 ordered pairs are
(5,1)
(0,-1)
(-5,-3)
