Answer:
Father age is 40 and Son age is 16
Step-by-step explanation:
Let Father be x and Son be y.
If their ratio of their age is 5:2 then
Find Y:
2x = 5y
- x = 5y/2
- 5y/2 = y+24
- 5y= 2y + 48
- 5y-2y = 48
- 3y=48
- y=48/3
- y = 16
Find X
- x=y+24
- x=16+24
- x=40

Answer:
decay; 8% decrease per time period
Step-by-step explanation:
The growth factor is the base of the exponential term. The growth rate is 1 less.
growth rate = 0.92 -1 = -0.08 = -8%
When the growth rate is negative, it is exponential decay withe the amount of decrease equal to the magnitude of the rate.
A growth rate of -8% represents exponential decay, with a decrease of 8% per time period.
Answer:
Consider the equation 3x + 2y = 12
Now, square both sides:
(3x + 2y)^2 = 122
=> 9x^2 + 12xy + 4y^2 = 144
=>9x^2 + 4y^2 = 144 – 12xy
From the questions, xy = 6
So,
9x^2 + 4y^2 = 144 – 72
Thus, the value of 9x^2 + 4y^2 = 72
