First let's find the mesure of the missing ANGLE: Missing angle = 180° - (42°+ 87°) = 51°

cos 51° = (adjacent side)/(hypotenuse) = x/43
<u />0.629320.91 = x/43
and x = 27.1

You are downloading a song. The percent y(in decimal form) of megabytes remaining to download after x seconds is y=-0.1x+1.

I would make the equation have both of your variables on the same side:

0.1x+y=1

Then I would use the cover-up method and say that

x-intercept= 10

y-intercept= 1


*Cover-Up Method: If you were finding the X-intercept, you would just ignore the y variable and divide your whole number by x.

In this case the whole number is 1. 1/0.1=10

Vice Versa with finding the Y-intercept

What is the distance between the two points (-8,-6) and (-2,4)?
MAVERICK [17]

Answer:

\sqrt{136} = 11.66 units

Step-by-step explanation:

distance between 2 points (a,b) and (c,d) = \sqrt{(a^{2}-c^{2} ) +(b^{2}-d^{2} ) }

= \sqrt{((-8)^{2}-(-2)^{2} ) + ((-6)^{2}-4^{2})   }

=\sqrt{136}

= 11.66 units

Answer:

  a) x = -3

  b) y = (28/27)x -27

Step-by-step explanation:

a) College street has a slope of 0, so is a horizontal line. 2nd Ave is perpendicular, so is a vertical line, described by an equation of the form ...

  x = constant

For 2nd Ave to intersect the point (-3, 1), the constant must match that x-coordinate. The equation is ...

  x = -3

__

b) Since Ace Rd is perpendicular to Davidson St, its slope will be the opposite reciprocal of the slope of Davidson St. The slope of Ace Rd is ...

  m = -1/(-27/28) = 28/27

Using the point-slope equation for a line, we can model Ace Rd as ...

  y -y1 = m(x -x1)

  y -1 = (28/27)(x -27)

  y = (28/27)x -27
