first of all we have the 5th term and 2nd term
T5=768 =a*r^4
T2=-12=a*r ^1
make a subject of formula in the both equations
that is a=T2/r and T5/r^4
a=12/r and a=768/r^4
when u equate them u will get
-64=r^3 so r=-4 then to find a that is 1st term
since second term is T2=a*r=12 an r=-4 then
a=12/-4 hence a=-3
Arc length = angle (in rad!!) * radius:
45 degree = pi / 4 rad
Arc length = pi/ 4 * 15 = 15/4*pi feet or approx. 11.781 feet
Also in this case only, 45 degrees is 1/8 of the whole circle, so Arc length = 2pir/8 = pi/4*r, but only this case. the first formula always works!
Answer: brooke had the faster time
Step-by-step explanation:
This is because if you convert 1 hour 45 into minutes it would be stated as 105 minutes and if you do 115 - 105 you are left with 10 which the bigger number is the fastest so it would be brooke the reason I subtracted was to see if they were not similar. Hope this helps :)
