lol nooooooooooooooooo
Step-by-step explanation:
The rate of interest is 25%
<u>Explanation:</u>
Given:
Principal, P = $2,000
Amount, A = $2500
Time, t = 1 year
Rate of Interest, r = ?
We know:
On substituting the value we get:
Therefore, the rate of interest is 25%
<span>180
n is the number of games. In this case it is 15. Enter this number into the function:
b(n) = 12n = 12(15) = 180.
Simply put, 12 balls are needed for each game.
15 x 12 = 180</span>
Answer:
<u>Option C. It is zero</u>
Step-by-step explanation:
The graph represents a quadratic equation
The quadratic equation has the form ⇒a x² + b x + c
The discriminant of the quadratic equation is D = b² - 4ac
From the discriminant of the quadratic equation, we can know the type of roots of the quadratic equation.
- If D > 0 ⇒ Two real roots.
- If D = 0 ⇒ one real roots
- If D < 0 ⇒ Two imaginary roots.
The roots of the quadratic equation are the x-intercepts of the function.
As shown at the figure, the quadratic equation has only one point of intersection with the x-axis
So, the function has only one root ⇒ D = 0
So, the discriminant of the quadratic equation = 0
<u>The answer is option C. It is zero</u>
