How do I find the missing sides in this triangle?
stiv31 [10]

Answer:

This is a 30-60-90 triangle so you would do this formula:

Short side (opposite the 30 degree angle) = x.

Hypotenuse (opposite the 90 degree angle) = 2x.

Long side (opposite the 60 degree angle) = x√3.

The sum of the angle measures of a triangle is 180°. Find the value of x. Then find the angle measures of the triangle.
MAXImum [283]

Answer:

  • x = 43
  • 43°, 51°, 86°

Step-by-step explanation:

The sum of the angles is ...

  x° + (x +8)° + 2x° = 180°

  4x +8 = 180 . . . . . . . . . . . collect terms, divide by °

  x +2 = 45 . . . . . . . . . . divide by 4

  x = 43 . . . . . . . . . . subtract 2

  x +8 = 51

  2x = 86

The angles are 43°, 51°, 86°.

Find an exponential model : Q is the population of bacteria in a Petri dish whose population was originally 150,000 but is tripl
Nadya [2.5K]

Answer:

150,000*3^t for 6 hour increments (t=1 is 6 hours t=2 is 12)

150,000*3^(t/6) for hourly increments, each t is 1 hour.  

Step-by-step explanation:

Well super simply you could do 150,000*3^t where t is measured in 6 hour intervals.  so t=1 is 6 hours, and to get 1 hour you would need to do t=1/6

If you want t to be an increase of every hour you would just need to adjust, like I showed before 1/6 gets one hour so 150,000*3^(t/6) would be the model where every t increases by 1 hour.

Write the following inequality in slope-intercept form. −6x + 2y ≤ 42
zubka84 [21]
Add the 6x to both sides. Then divide both sides by 2 to get y by itself.

y <= 6x + 42

Note: if it were a -2y, you’d have to flip the inequality sign when dividing by that negative 2.
