Answer:

r = -2 or r = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

r2−r−6=0

Step 2: Factor left side of the equation.

(r+2)(r−3)=0

Step 3: Set factors equal to 0.

r + 2 = 0 or r − 3 =0

r = −2 or r = 3

PQ= 2x +1 and QR= 5x - 44; find PQ
Lena [83]

2x+1=5x-44 that would be your equation

next start to simplify 

subtract 1 from both sides so you are left with 2x=5x-45

then subtract 5x from both sides and you have -3x=-45

then finally divide -3 from -45 to get x=15

C) true, because the standard deviation describes how​ far, on​ average, each observation is from the typical value. a larger standard deviation means that observations are more distant from the typical​ value, and​ therefore, more dispersed.

Answer:

(B)1005 feet

Step-by-step explanation:

In the attached diagram

\angle y =82^\circ\\\angle x =60^\circ

|AG|=1400 feet

Distance from point C to point G=|CG|

Using Trigonometry in Triangle ACG

\tan 60^\circ=\dfrac{1400}{CG}\\ CG=\dfrac{1400}{\tan 60^\circ}\\\approx 808$ feet

Using Trigonometry in Triangle BCG'

\tan 82^\circ=\dfrac{1400}{CG'}\\ CG'=\dfrac{1400}{\tan 82^\circ}\\\approx 197$ feet

Therefore, the distance from balloon B from balloon A

=CG+CG'

=808+197

=1005 feet
