Answer:

2,340,208.5 or 2,340,209

Step-by-step explanation:

You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times.  But that would take a while.

we got 1.05 because the formula says that y = a( 1 + r ) power t

for a we will give it 1

so y = 1 ( 1 + 0.05) power t

it will give us 1.05

to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.

So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209

Write the equation of the line in
Brut [27]

Answer:

y - 3= 2(x - 0)  

Step-by-step explanation:

hello :

note 1 :

the point-slope formula is :

y - y_1 = m(x - x_1)   the point is A(x_1  , y_1 )  , m :  the slope

note 2 :

the slope is :   m = (y_2 - y_1)/(x_2 -x_1)  when given two points  :

A(x_1  , y_1 )  and  B(x_2  , y_2 )

in this exercice :  x_1 =0      y_1 =3            x_2 =1      y_2 =1

calculate now   m = (1 - 3)/(1 -0) =-2

an equation  in point-slope form is : y - y_1 = m(x - x_1)  

y - 3= 2(x - 0)

The value of a boat is $23,400. It loses 8% of its value every year. Find the approximate monthly percent decrease in value. Rou
Oduvanchick [21]
23400 x 8/100 = 1872 = the loss
1872 : 12 = 156= the loss each month
156/1872*100% = 8,33 % then round it

The equation of line QR is y = negative 1 over 2x + 1. Write an equation of a line perpendicular to line QR in slope-intercept f
Vesnalui [34]
Any perpendicular line has a negative reciprocal slope. So your slope would be 2. The. You would have the equation : y=2x+b. You would then replace the coordinate (5,6) with x and y on your line to solve for b. Your equation would be : y=2x-4
