Answer:
1. b=-7
2. c= -10
Step-by-step explanation:
The standard form for the quadratic function is
ax^2 +bx+c
so we need to rewrite the function to be in this form
2x^2 -10 = 7x
Subtract 7x from each side
2x^2 -7x-10 = 7x-7x
2x^2 -7x-10 = 0
a =2, b= -7 c=-10
The factors in this expression are 3 and 4. Hope this helps! =)
The polar coordinates of (-4, 150°) will be and 5069.09939523°
<h3>What is the coordinate about?</h3>
The formula for this conversion will be:
