Answer:

37.52 feet

Step-by-step explanation:

Given in the question the equation

h = -16t² + 47t + 3

<em>where h is height in feet </em>

<em>             t is time in minutes</em>

<em />

a = -16

b = 47

c = 3

To find the maximum height of the football

  1. If a, the coefficient of the x² term, is positive, then the parabola opens upward. If a is negative, then the parabola opens downward. In this case it is -16 which is negative so it open downward.
  2. The value of -b/2a tells you the x value of the vertex of the curve at which it is maximum
  3. Plug this value in the equation to find h, maximum height.

t = -b / 2a

 = -47 / 2(-16)

 = 1.47 sec  

h = -16(1.47)² + 47(1.47) + 3

  = 37.52 feet

The midpoint of AB is M(−3,2). If the coordinates of A are−7,1), what are the coordinates of B?
sergejj [24]

Answer:

B = (1,3)

Step-by-step explanation:

(- 7 + x)/2 = -3

-7 + x= -3 * 2

x = -6 + 7

x = 1

(1 + y)/2 = 2

1 + y = 2*2

y = 4 - 1

y = 3

Using these coordinates, find the slope. (0, -6), (3, -2)
seropon [69]

Answer:

The slope between the points (0, -6) and (3, -2) will be:

  • m=\frac{4}{3}

Step-by-step explanation:

Given the points

  • (0, -6)
  • (3, -2)

The slope between the points (0, -6) and (3, -2) will be:

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:-6\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)

m=\frac{-2-\left(-6\right)}{3-0}

m=\frac{4}{3}

Therefore, the slope between the points (0, -6) and (3, -2) will be:

  • m=\frac{4}{3}
