For these questions to be true and the equation of the tangent to have an equal y to the equation of the parabola i guess there has to be a "c" and in that case integrate the equation of the tangent you will have a = 5 and b = -18 then you substitute in the equation of the parabola with the point you have you will find that "c" = 21 and so the equation of the parabola becomes y = 5x^2 - 18 x +21

The ratio of the longer side of a rectangle to its shorter side is 4 to 3. If the shorter side of the rectangle is 21ft, what is
Eduardwww [97]

Answer:

28 ft


Step-by-step explanation:

Let longer side of rectangle be L and the shorter side be  S, thus we can write the ratio:

\frac{L}{S}=\frac{4}{3}


<em>Now putting 21 into S, we solve for L:</em>

\frac{L}{21}=\frac{4}{3}\\3L=4*21\\3L=84\\L=\frac{84}{3}=28


Hence, length of longer side is 28 ft.

The graph shows the velocity f(t) of a runner during a certain time interval:
omeli [17]

Answer:

Option B

Step-by-step explanation:

  • (0,2)
  • (6,8)
  • (8,0)

Slope

  • m=8-2/6
  • m=6/6=1

And

  • m=0-8/8-6
  • m=-8/2
  • m=-4

These are acceleration

Y intercept is (0,2) as x coordinate is 0

This is initial velocity 2m/s

The runner stopped at 8s
