Graph the equation h=-16t^2+80. click on the graph until the correct solution appears

The graph of the equation h=-16t^2+80 is shown in the figure attached.

The y-intercept is obtained replacing t = 0 in the equation, as follows

h=-16(0)^2+80 = 80

The x-intercepts are obtained replacing h = 0 in the equation, as follows

0=-16t^2+80

16t^2 = 80

t^2 = 80/16

t = √5

t ≈ -2.236 or  t ≈ 2.236

With this 3 points, (0, 80) (-2.236, 0) (2.236, 0)  the curve of a quadratic equation is defined.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
