For a better understanding of the solution provided here please find the diagram in the file that has been attached. As shown in the diagram, the sea level is taken as the "zero level" thus making 35 feet below sea level as -35 and making 2 feet above (or in the air) as +2 (or simply 2).
The fish was at P1 (35 feet below sea level or, -35) to start with and jumped to P2 (2 feet above sea level, or 2), so the total distance travelled by the fish is the distance between the positions of P1 and P2 which can be shown as:
feet.
Therefore, the fish travelled a total of 37 feet from it's previous position which was 35 feet below the sea level.
The level of radioactivity in the soil is decreasing by a factor of 1/2 each month
Answer:
A
Step-by-step explanation:
Just by looking at the graph you can eliminate some silly answers such as D and B, everything besides the slope is obvious at least:
The y int is -2
The line is negative
The standard parent function equation is just y = x with a slope of 1.
This graph is clearly a bit steeper than the normal parent function, so it has a slope that is great than -1, not less . So the only answer left is A
If you want to be sure, you can calculate the slope using rise over run and the slope should be somewhat close to -1.5 which is equal to -3/2
Thanks me later :)
M+4n=8
m=n-2
we see that m=n-2
so we can subsitute 'n-2' for m in the first equation
(n-2)+4n=8
n-2+4n=8
5n-2=8
add 2 to both sides
5n=10
divide by 5
n=2
subsitute
n=2
m=n-2
m=2-2
m=0
m=0
n=2
the answer is c. 0,2
