angle 2 = 114°
supplementary angles sum to 180° thus
5y + 16 + 10y + 14 = 180
15y + 30 = 180
subtract 30 from both sides
15y = 180 - 30 = 150
divide both sides by 15
y = = 10
angle 1 = (5 × 10) + 16 = 50 + 16 = 66° and
angle 2 = (10 × 10) + 14 = 100 + 14 = 114°
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:
Step-by-step explanation:
The given functions are:
and
We want to to find
Note that:
We substitute the functions to obtain:
We now substitute x=7, to get:
This implies that
