Answer:
The mechanic will need to finish in 4 hours.
Step-by-step explanation:
100+40=140
40+40=80
40+40=80
40
140 +80 + 80+ 40= 340
The equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0) is
<h3><u>Solution:</u></h3>
We have to find the equation of a parabola that opens up and has the following x intercepts (-3, 0) and (4, 0)
x-intercepts of the parabola are (−3, 0) and (4, 0)
So, we can form an equation:
Also x = 4
x – 4 = 0
x – 4 = 0 is another factor of quadratic equation.
The quadratic function is:
Hence, the equation of the parabola is
