Find the distance between two points. ENTER THE NUMBER THAT GOES BENEATH THE RADICAL SYMBOL.
iVinArrow [24]
<h2>The distance between two points is \sqrt{98} or 9.9 units</h2>

<em><u>Solution:</u></em>

<em><u>The distance between two points is given as:</u></em>

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}

From given,

(x_1, x_2) = (-5, 5)\\\\(x_2, y_2) = (2, -2)

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

d = \sqrt{(2+5)^2+(-2-5)^2}\\\\d = \sqrt{7^2+(-7)^2}\\\\d = \sqrt{49+49}\\\\d = \sqrt{98}\\\\d = 9.899 \approx 9.9

Thus the distance between two points is \sqrt{98} or 9.9 units

Algebra 1 Grade 9.
Leya [2.2K]

Answer:

627.65 times

2.51^(10 - m) times

Yes, it makes sense

Step-by-step explanation:

Given that,

A magnitude 9 star is 2.51 times as bright as a magnitude 10 star

To find

<h3>a) </h3>

How many times as bright is a magnitude 3 star as a magnitude 10 star

10 - 3 = 7

2.51^7

627.65 times

<h3>b)</h3>

Expression to compare a magnitude m star to a magnitude 10 star

2.51^(10 - m) times

<h3>c)</h3>

Yes, it makes sense as a full moon is magnitude -13

so,

2.51^(10 - (-13))

2.51^(23)

1557742231 times
