Answer:
3.5 hours
Step-by-step explanation:
The buses are separating from each other at a speed of 73+79 = 152 miles per hour. Since time = distance/speed, the time it takes to be 532 miles apart is ...
time = (532 miles)/(152 miles/hour) = (532/152) hours = 3.5 hours
the height can be given as
AB = a sin theta
here a = 4 and theta is 60 so
AB = 4 sin 60 = 4 × √3/2 = 2√3
so area of a parallelogram is
= base × height
= 7 × 2√3 = 14√3
I'm really sorry, I'm not the best at this, but I did all the equations the best to my knowledge and came up with these 3 answers
(2,-1) which equaled -7
(5,4) which equaled -11
and (0,-9) which equaled - 9
Again I'm really sorry if this didn't work. :( God bless and good luck with future lessons.
X + 1 + X + 1 + X +1+ X +1 = 2X -3+ 2X -3+ X -1+ X -1
4x + 4 = 4x-6+2x-2
4x+4=6x-8
12=2x
6=x
Side lengths:
6-1=5
6+1=7
2(6)-3=9
Hope that helps! Stay safe!
