In 2004 the population in Morganton, Georgia, was 43,000. The population in Morganton doubled by 2010. If the growth rate remain
zheka24 [161]

Answer:

263,606.9

Step-by-step explanation:

In 2004 the population in Morganton, Georgia, was 43,000.

(0, 43000)

The population in Morganton doubled by 2010

In 6 years the population is doubled (86000)

(6,86000)

A= a(b)^t

Use (0,43000) in the above equation

A= a(b)^t\\43000= a(b)^0\\a=43000

Now plug in (6,86000)

A= a(b)^t\\A= 43000(b)^t\\86000=43000(b)^6\\2=b^6\\b=\sqrt[6]{2} \\b=1.12

A=43000(1.12)^t

Now find out A when t=16 (2020)

A=43000(1.12)^t\\A=43000(1.12)^{16}\\A=263606.9

A car rental company charges a base fee of $30 per day to rent a car, along with an additional $0.18 per mile driven. If George
sladkih [1.3K]

George's cost per day is

... c = 30 + 0.18m

We want c < 55, so we can write

... 30 + 0.18m < 55 . . . . . your inequality

_____

Here is the solution to the inequality

... 0.18m < 25

... m < 25/0.18

... m < 138.9

George must drive less than 138.9 miles that day.

If (a+b)^2=54, and (a-b)^=46, then a^2+b^2=?
erastovalidia [21]

(a+b)^2 =a^2 +b^2 + 2ab = 54~~~.....(i)\\\\(a-b)^2 = a^2 +b^2 -2ab = 46~~~.....(i)\\\\\\(i)+(ii):\\\\(a+b)^2 +(a-b)^2  = 54+46\\\\\implies a^2 +b^2 + 2ab + a^2 +b^2 - 2ab =100\\\\\implies 2a^2 +2b^2 =100\\\\ \\\implies 2(a^2 +b^2) =100\\\\\implies a^2 +b^2 = \dfrac{100}2 = 50

What expression is not equivalent to 1/343
GREYUIT [131]
1 / 343
This is just equal to 
1 / 7^3 = 7^-3

A. 7^-1 * 7^-2 = 7^(-1 + -2) = 7^-3
B. 7^7 * 7^-10 = 7^( 7+ -10) = 7^-3
C. 7^-2 * 7^-5 = 7^(-2 + -5) = 7^-7
D. 7^-5 * 7^2 = 7^(-5 + 2) = 7^-3

So the correct answer is letter C. 7^-2 * 7^-5
