Start by adding 34 to both sides so that the equation becomes -7x^2 + 3x + 6 = 0. To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac)] /(2a)
x = [-3 ± √((3)^2 - 4(-7)(6)) ] / ( 2(-7) )
x = [-3 ± √(9 - (-168) ) ] / ( -14 )
x = [-3 ± √(177) ] / ( -14)
x = [-3 ± sqrt(177) ] / ( -14 )
x = 3/14 ± -sqrt(177)/14
The answers are 3/14 + sqrt(177)/14 and 3/14 - sqrt(177)/14.
The only zero of this function is (0, 0). this is where the graph goes through the x-axis. It's the only place, actually. So the zero is z = 0, and when x = 0, y also happens to equal 0
Answer:8 hours
Step-by-step explanation: There are 250 samples, but there are only actually 200, since 50 need to be on display. That means that they will last 200/25=8 hours.
Answer:
First way:
1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10 + 1/10
Second way:
4/10 + 3/10
