a) The half-life equation is given by:
b) Using the decay equation we have:
we need to find t when
Therefore, it will take 4820 years to decay to half the original amount.
I hope it helps you!
Answer:
no solution
Step-by-step explanation:
ya gotta use your eyes and brain huney. it aint that hard. kk? but ill still explain for you.
since x+y=6 and x+y=4. then 4=6. but that is false so no solution.
YOUR WELCOME!
You can use the sin function to solve this.
Think of a triangle with the conveyor being the longest side (hypotenuse). The height (the vertical side) is H=17m. The angle of elevation is a=36.2. We are looking for length of the hypotenuse, L.
The sin is the ratio of height to hypotenuse: sin(36.2) = H/L = 17/L
Now solve for L:
L = 17/sin(36.2) = 17m/0.59 = 28.78m
The conveyor needs to be approx. 28.8m long to get close to the max. efficient angle.
Answer:
7/40
Step-by-step explanation:
12-5=7
54-14=40
7/40
For the given expression, there is a -1 inside the function and + 4 with the function.
Because of -1 inside the function, the graph shift by 1 unit towards right and because of +4 with the function, the graph shifts to 4 units up .
So the correct option is the first option .
