You launch a water balloon. The function h=-0.08t^2+1.6t+2 models the height h (in feet) of the water balloon after t seconds. W
stellarik [79]

Answer:

The initial height of the balloon is 2 feet.

Step-by-step explanation:

The height of the balloon in feet after t seconds is given by the following equation:

h(t) = -0.08t^{2} + 1.6t + 2

What is the initial height of the balloon?

This is h when t = 0, that is, h(0). So

h(0) = -0.08*0^{2} + 1.6*0 + 2 = 2

The initial height of the balloon is 2 feet.

a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form
Elena L [17]

Answer:

\huge  \orange{y =  -  \frac{1}{9} x} \\

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have

y + 1 =  -  \frac{1}{9} (x - 9) \\ y + 1 =  -  \frac{1}{9} x + 1 \\ y =  -  \frac{1}{9} x + 1 - 1

We have the final answer as

y =  -  \frac{1}{9} x \\

Hope this helps you
