The half-life of a certain substance is years. How long will it take for a sample of this substance to decay to % of its original amount? Use the exponential decay model, , to solve. e^8x-5 -3=25,059

i dont understand the question? ?

step-by-step explanation:

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

b. hoped i'm right lol
