Step-by-step explanation:
Given that,
A quadratic equation,
2x(x + 1.5) = -1
We need to solve the quadratic equation. Firstly we need to simplify the above equation to form it as .
So,
Here, a = 2, b = 3 and c = 1
The roots of the given equation can be given by :
Putting all the values we get :
So, the roots of the given equation is -1/2 and -1.
Answer:
$960
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.
<em>I = interest amount </em>
<em>P = principal amount </em>
<em>r = interest rate (decimal form) </em>
<em>t = time </em>
The first step is to change 3% into a decimal:
3% -> -> 0.03
Now, lets plug in the values into the equation:
Jameson will be charged $960 of interest after 4 years.
