Answer:
1. 2 real solutions
2. no real solutions
3. 2 real solutions
4. 1 real solution
Step-by-step explanation:
The 'solution' to a quadratic equation means the x - intercepts of a graph, so how many times the parabola crosses the x-axis.
Set up an system:
x+y=52
x=y-2
Substitute in:
(y-2)+y=52
2y-2=52
2y=54
y=27
27-2=25
The answers are 27 and 25
Answer:
c. 12.48
Step-by-step explanation:
The earnings per share after t years can be modeled by the following equation:
In which E(0) is the earnings last year and r is the growth rate, as a decimal.
Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year. Growth rate maintained.
This means that
So
If that growth rate were maintained, how many years would it take for Brockman's EPS to triple?
This is t for which E(t) = 3*E(0) = 3*3.50 = 10.50.
So
So the correct answer is:
c. 12.48
