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
Answer:
5
Step-by-step explanation:
It's an equilateral triangle
Y= 2x-4
4x+Y=2
4x+2x-4=2
6x-4=2
+4=+4
6x=6
6/6X = 6/6 X=1
Y=2X-4
2(1)-4
Y=-2
Answer:
132 miles away from his startnig point
Step-by-step explanation:
1. num of minutes 2,
distance traveled 200 yds
average rate of speed 100 yds/min
2. num of minutes 2
distance traveled 400 yd
average rate of speed 200 yd/min
3. num of minutes 4
distance traveled 600
average rate of speed 150 yd/min
4 he ran faster in the last two minutes
5. yes because it passes the vertial line test. it is linear
