1 answer:

7 0

The initial value is 3. The common ratio is -9/3 = -3. The general formula is
.. an = a1*r^(n-1)

So, for your values, ...
.. an = 3*(-3)^(n -1)

Austin takes 1 minute and 45 seconds to run three-quarters of a circular track. His rate of motion is /

castortr0y [4]

Length of circular track is:

L = 2*r*pi

He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi

To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds

v = L'/t = 3*r*pi/2*105

v = r* pi/70

If we take that r = 1

answer
$\pi /70$

PLEASE HELP ITS DUE TODAY URGENT!

vlada-n [284]

Step-by-step explanation:

7. ∆ABC = ∆ILH by SSS

as, AB = IL , BC = LH , CA = HI

8. ∆DEF = ∆AMS by ASA

as , angle D = angle A, EF = MS , angle F = Angle S

9. ∆JKL = ∆HAT by SAS

as, JK = HA , KL = AT , angle L = angle T

10. ∆ABC = ∆KPG by ASA

as , CA = GK, Angle c = angle G and Angle B = angle P

11. ∆ABC = ∆YDE by ASA

as , angle A = angle Y, AB = YD , angle B = angle D

12. ∆MNO = ∆SAK by ASA

as , Angle M = angle S, NO = AK, angle O = angle K

hope this answer helps you dear...and may u have a great day ahead!

4 1/3 into a fraction

katrin [286]

I think you have to make 4 1/3 into an improper fraction that is 13/1 because 4*3=12 12+1=13. Then you divided 13/1(on a calculator you get a decimal) your will be 1 3/11
