Solve and graph the equation x2+x-6=0

Mathematics
1 answer:

Y=x²+x-6 (original form ax²+bx+c)

1) this is a parabola open upward since the coefficient of x² is positive
so it has a minimum.

2) Its symmetry line = -b/2a = -1/2 & for x=-1/2, y= 23/4
So its minimum is (-1/2, 23/4)

3) Now to see if the parabole intercepts the x-axis we calculate the roots of
x²+x-6. As you will notice Δ <0 so there is no roots & consequently it doesn't intersect with x-axis
Your graph is wrong, and the parabola should be above the x-axis & it will intersect with the y-axis at y=23/4 =5.75nunits

A basketball team took a total of 100 shots. One player took 70% of all 100 shots, and
NemiM [27]

The player took a total of 70 shots and missed about 28 shots.

<h3>Percentage</h3>

Percentage is used in expressing a fraction number or decimal in fraction of 100. It is expressed using the '%' sign.

Given a total shot of 100, since the player took 70% of the shot, hence:

Total shot taken by the player = 70% of 100 = 0.7 * 100 = 70 shots.

Total shot shot missed = (100% - 60%) of 70 = 40% of 70 = 0.4 * 70 = 28 shots.

The player took a total of 70 shots and missed about 28 shots.

HELP!!
taurus [48]

Lets convert

  • 1mile=5280ft
  • 1h=3600s

\\ \rm\longmapsto 1mph

\\ \rm\longmapsto \dfrac{5280}{3600}ft/s

\\ \rm\longmapsto 1.46ft/s

If rounded

\\ \rm\longmapsto 1.5ft/s
