Answer:

  process: substitute the given point values into the 2-point form of the equation for a line

Step-by-step explanation:

There are more than a half-dozen different forms of the equation for a line. They are useful for different purposes. One of them is the "two-point form".

Using x as the independent variable, and y as the dependent variable, the equation can be written as ...

  y -y1 = (y2 -y1)/(x2 -x1)/(x -x1)

where (x1, y1) and (x2, y2) are the two points.

__

Here, your two points are ...

  (t, s) = (10, 337) and (30, 349)

Using s in place of y, and t in place of x, these two points go into the formula like this:

  s -337 = (349 -337)/(30 -10)(t -10)

Simplifying the fraction, this is ...

  s -337 = (12/20)(t -10)

And writing it as a decimal, we get ...

  s -337 = 0.6(t -10)

_____

<em>Additional comments</em>

Adding y1 to both sides of the above form gives you ...

  y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

This is the form I usually prefer to use, because it can lead directly to slope-intercept form. For this problem, the form shown above gets you to the answer you're looking for.

__

This "two-point form" is an expansion of the "point-slope form", which is ...

  y - k = m(x -h) . . . . . . . line with slope m through point (h, k)

where the equation for slope is ...

  m = (y2 -y1)/(x2 -x1)

and (x1, y1) is used instead of (h, k).

What is DE ?<br><br> Enter your answer as a decimal in the box.<br><br><br> ____ units
Fantom [35]
<span>6.3 Looking at the triangle, you can see that point D bisects line segment AB and that point E bisects line segment BC. In fact, you can easily determine that triangles ABC and DBE are similar triangles with DBE having sides that are half the length of the respective sides in ABC. And since line segment DE corresponds to line segment AC which is 12.6 units long, line segment DE is 12.6/2 = 6.3 units long.</span>

Answer:

a = 36.37 cm

c = 18.19 cm

Step-by-step explanation:

to find a, use tan

⇒ tan = \frac{opposite}{adjacent}

⇒ tan 60 = \frac{21}{a}

tan of 60 is 1.732

⇒ 1.732 = \frac{21}{a}

multiply 21 on both sides

⇒ 1.732 x 21 = \frac{21}{a}x 21

⇒ 36.37 = a

to find c, use sine

⇒ sine = \frac{oppsosite}{hypotenuse}

⇒ sine 60 = \frac{21}{c}

sine of 60 is 0.866

⇒ 0.866 = \frac{21}{c}

muliply 21 on both sides

⇒ 0.866 x 21 = \frac{21}{c} x 21

⇒ 18.19 = c
