Answer:
x=6 cm
Step-by-step explanation:
As given in the question that ABCD is congruent to EFGH.
We can say that,
AD <-----> EH {Corresponding Parts Of Congruent Polygons}
AD=EH
We are given that,
5√18
= 5 *√9 *√2
= 5*3*<span>√2
= 15</span><span>√2</span>
Answer:
6967 years
Step-by-step explanation:
Given the exponential function :
R=100e−0.00043t
Time = t in years
R = final amount
Number of years in which only 5 grams of radium will be present :
R = 5
Plugging into our formula :
5 = 100 * e^−0.00043t
5 / 100 = e^−0.00043t
0.05 = e^−0.00043t
Take the In of both sides
−2.995732 = - 0.00043t
t = −2.995732 / - 0.00043t
t = 6966.819
t = 6966.819 years
t = about 6967 years
