Answer:
(x) = ax 2 + bx + c has a negative leading coefficient and the vertex that has a negative y-coordinate. Determine the number of
real zeros of the function.
1 answer:
The number of real zeroes are the x intercepts or where the graph touches the x axis
negative leading coeficnet means it opens down
negative y coordinate means that the highest point is below the x axis
since it opens down and it is below the x axis, there is no x intercept or real solution (see attachment)
thereforr there are no real roots, there are zero real roots, nada, zip

Answer:
II case.
Step-by-step explanation:
Given that a catering company prepared and served 300 meals at an anniversary celebration last week using eight workers.
The week before, six workers prepared and served 240 meals at a wedding reception.
Productivity is normally measured by number of outputs/number of inputs
Here we can measure productivity as
no of meals served/no of workers
In the I case productivity =
In the II case productivity =
Obviously II case productivity is more as per worker 40 meals were served which is more than 37.5 meals per worker in the I case.
Answer:
Outside of the circle
Step-by-step explanation:
First, find the equation of the circle by plugging in the center point and radius:
(x - h)² + (y - k)² = r²
(x - 0)² + (y - 0)² = ()²
x² + y² = 12
Plug in point M to see where it lies:
x² + y² = 12
(-3)² + (2)² = 12
9 + 4 = 12
13 ≠ 12
Since this statement is false, point M lies outside of the circle.
