Answer:
element remained after 14 minutes = = 7.091 g =~ 10 g
Step-by-step explanation:
After every minute the amount remained will be
(100 - 26.9 ) % i.e. 73.1 %
which is 0.731 times as much as the amount was at the start.
if the number of minutes passed is represented by t the function f(t) represents the mass of element remaining our equation will be
f(t) = 570( 0.731) ^ t
t= 14 minutes
f(14) = 570 ( 0.731) ^ 14
= 7.091 g =~ 10 g
Sketch a right triangle, with hypotenuse = 425. Solve for y, the side opposite the 47-degree angle, using the sine function.
Sin 47 = opp / hyp
Sin 47 = y / 425
Y= 425 times (Sin 47)
Y= 425 times (????) [evaluate Sin 47]
