Answer:
A
Step-by-step explanation:
Substitute the given values into the expression
2a² + cb
= 2(5)² + 3(11)
= 2(25) + 33
= 50 + 33
= 83 → A
The amount an employee has to pay for a pair of shoes, is $56, but there is no $56 option, so the only other answer it could be is C. $57
Step-by-step explanation:
The axis of symmetry: is the line that makes the parabola split in exactly half and lines up with the vertex. For that parabola x=1 is the line of symetry.
The vertex is where the minimum of the graph is, on this graph you can eyeball it to be (1,-9)
The x-intercept is where y is 0 so that's where the lines intersex with the x-axis. (-2,0) and (4,0)
The y-intercept of the function is where x is 0 and where the parabola intersects with the y-axis. On this graph it would be (0,-8)
Hope that helps :)
Answer:
2.50
Step-by-step explanation:
The average rate of change over the interval −2≤x≤2 is:
(f(2) − f(-2)) / (2 − -2)
From the table, we see that f(2) = 14 and f(-2) = 4.
(14 − 4) / (2 − -2)
10 / 4
