Answer:
14 years
Step-by-step explanation:
Using the general growth formula
where F is future population, P is present population, n is years and r is rate in percentage.
Substituting 26000 for future population F, 19000 for present population P and 2.3% for rate
Introducing natural logarithms on both sides
n ln 1.023=ln(\frac {26000}{19000})[/tex]
n=(ln 26/19)/(ln 1.023)=13.79351958 years
Rounding off, n=14 years
About 84.82
Step-by-step explanation:
The formula to find the volume of a cone is pi*r^2*(h/3). The formula to find radius is diameter/2. 6/2=3. Since r=3 and h=9, pi*3^2*(9/3)=84.82
Answer:
x=-6
Step-by-step explanation:
The x coordinates are the same, so we know that we have a vertical line.
Vertical lines have no slope, so they are in the form
x=
Since the x coordinate is -6
x=-6

Answer:
x = -1/4, y = 5/4.
Step-by-step explanation:
Because of the absolute value equation y = |x - 1| the value of y must be positive.
Solving x - 1 = 3x + 2 :
2x = -3
x = -3/2 and y = -5/2 so x= -3/2 is not a solution.
x - 1 xcan also be negative so we have the equation
- (x - 1) = 3x + 2
1 - x = 3x + 2
-1 = 4x
x = -1/4
y = 1 - - 1/4 = 5/4.
