Lucy's spaceship is low on fuel. Lucy is 1{,}2001,2001, comma, 200 light years (\text{l.Y.}l.Y.Start text, l, point, y, point, e

nd text) from the star system KA-7, as shown. She is 1{,}700\,\text{l.Y.}1,700l.Y.1, comma, 700, start text, l, point, y, point, end text from the system KA-11. Lucy sees an angle of 52\degree52°52, degree between KA-7 and KA-11. To decide whether to visit KA-11, Lucy needs to know the distance between the systems. How far apart are KA-7 and KA-11? Do not round during your calculations. Round your final answer to the nearest hundred light years.

Find the value of x. Write your answer as a simplified radical if necessary.
Andreas93 [3]

Answer:

x=5

Step-by-step explanation:

The right angle opposite is the hypotenuse

The 30° is the opposite

SohCahToa

Soh = Sin because you got Opposite and Hypotenuse (because you're trying to find the side, you'd do the opposite of dividing, which is times)

10×sin(30)=5

EXPLAIN THE ERROR Cody was given two points (1/2,4) and (2/3,1), on a line and asked to create a linear equation in standard for
inessss [21]

Answer:

Cody made a mistake when calculating the slope of the line and this affected every other steps after than.

She divided -3 by 6 instead of -3 by 1/6

Step-by-step explanation:

Given

(x_1,y_1) = (\frac{1}{2},4)

(x_2,y_2) = (\frac{2}{3},1)

<em>See attached for steps</em>

Required

Explain Cody's error

<em>Cody made a mistake when calculating the slope of the line and this affected every other steps after than.</em>

See Proof

Slope (m) is calculated as thus:

m =\frac{y_2 - y_1}{x_2 - x_1}

m =\frac{1 - 4}{\frac{2}{3} - \frac{1}{2}}

m =-\frac{ 3}{\frac{1}{6}}

m = -3/\frac{1}{6}

m = -3 * 6

m = -18

This is in contrast to m = -\frac{1}{2}, calculated by Cody

Solving further to determine the equation.

y - y_1 = m(x - x_1)

Where

(x_1,y_1) = (\frac{1}{2},4)

m = -18

y - 4 = -18(x - \frac{1}{2})

y - 4 = -18x + 9

Collect Like Terms

y + 18x = 9 + 4

y + 18x = 13
