The answer is 24,576.
P(x) = P(0) * nˣ
P(x) - the final population after period x
P(0) - the initial population
n - the growth factor in decimal
x - period of time
P(6) = ?
P(0) = 6
n = 4
x = 6 months
P(6) = 6 * 4⁶
P(6) = 6 * 4096
P(6) = 24,567
Answer: C
Step-by-step explanation: Cross multiply.
36/90 = x/100
3600/90 = 40
Call Martha's age 5 years ago is x So Martha father's age five years ago is 7x
We have : 7x + 5 = 4(x + 5)
3x = 25+5=30 so x = 5 so Martha's present age is 10 and her's father's present age is 40

Answer: B) x + y = 17
1.60x + 2.45y = 34
Step-by-step explanation:
Cost of x = $1.60 per pound
Cost of y = $2.45 per pound
Total pounds of x and y = 17
Cost per pound of mixture = $2
Total number of pounds of the mixture :
x + y = 17
Since the cost per pound of the mixture = 2
Hence ;
(Cost of x * number of pounds of x) + (Cost of y * number of pounds of y)
(1.60 * x) + (2.45 * y) = (cost per pound of mixture * total number of pounds of the mixture)
1.60x + 2.45y = 2 * 17
1.60x + 2.45y = 34
Answer:
5/2 or 3/2
Step-by-step explanation:
(2x-3)(2x-3)
FOIL it out
4x^2-6x-6x+9
4x^2-12x+9=4x-6
add 12x to each side
4x^2+9=16x-6
add 6
4x^2+15=16x
4x^2-16x+15=0
use quadratic formula
