Answer:

17.3 =x

Step-by-step explanation:

The Pythagorean theorem is

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

3^2 +17^2 = x^2

9+289 = x^2

298 = x^2

Take the square root of each side

sqrt(298) = sqrt(x^2)

17.2626765 = x

Rounding to the nearest tenth

17.3 =x

Answer:

17.3

x² = 9 + 289

x² = 298

x = 17.2626765

x = 17.3

The equation $y=-4.9t^2+3.5t+5$ describes the height (in meters) of a ball thrown upward at $3.5$ meters per second from $5$ met

Georgia [21]

Answer:

Step-by-step explanation:

The position function is

$s(t)=-4.9t^2+3.5t+5$ and if we are looking for the time t it takes for the ball to hit the ground, we are looking for the height of the ball when it is on the ground. Of course the height of anything on the ground is 0, so if we set s(t) = 0 and solve for t, we will find our answer.
