Answer:
y = 30(2)^x
Step-by-step explanation:
Initial deer population = 30 (in 2010)
Every year, deer population doubles ; this means there is an 100% increase in the population every year ;
Hence, using the exponential growth relation :
Final = initial * (1 + rate)^year
Here,
Final population y ; x years after 2010
Rate = 100% = 1
Hence,
y = 30(1 + 1)^x
y = 30(2)^x
Answer:
v = ± 
Step-by-step explanation:
Given
E =
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ± 
Answer:
The answer is (-0.7, -9.4)
Step-by-step explanation:
1) Since we are using the substitution method, and we know that y = 2x-1, in the first equation, plug that into y. It should look like this:
4x-2(12x-1) = 14
4x -24x + 2 = 14
2) Combine like terms and continue to simplify until you get a direct answer for each variable.
-20x + 2 = 14.
-20x = 12.
x = -7/10 (or -0.7)
3) Now we know what x equals, so to find our y-coordinate, we will plug this into either equation.
y = 12(-7/10) -1
y= -84/10 -1
y= -9.4
4) Now that we have our x value and y value, we know our point. The solution is (-0.7, -9.4).
To find 2/3 of an hour first we will divide 1 hour that is 60 mins into 3parts so we will get 20 mins.
