The diameter is about 49.1
You can find this using the equation: 31^2 = 15 x (15+diameter)
Hope this helped!!
Naw bruv i’m doing the same problems rn and i’m struggling gl tho
Answer:1
Step-by-step explanation:
The answer is C because when you use the vertical test it only passes through one line
The solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots
To determine the the type of roots the quadratic equation 9x² - 6x + 5 = 0, we use the quadratic formula to find the roots.
So, for a quadratic equation ax + bx + c = 0, the roots are
With a = 9, b = -6 and c = 5, the roots of our equation are
Since the roots of the equation are (1 + 2i)/3 and (1 - 2i)/3, there are 2 complex roots.
So, the solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots
