A circle centered at the origin contains the point

Answer:

Yes, the distance from the origin to the point (8,√17) is 9 units.

Step-by-step explanation:

The equation of a circle centered at the origin with radius , r has equation:

{x}^{2}  +  {y}^{2}  =  {r}^{2}

Since the circle passes through (0,-9), the radius is 9 units because (0,-9) is 9 units from the origin.

We substitute the radius to get:

{x}^{2}  +  {y}^{2}  =  {9}^{2}

{x}^{2}  +  {y}^{2}  =  81

If (8,√17) lies on this circle, then it must satisfy this equation:

{8}^{2}  +  { (\sqrt{17} )}^{2}  = 64 + 17 = 81

This is True.

This means the distance from (8,√17) is 9 units from the origin.

Answer:

- time = 1second

- maximum height = 16m

Step-by-step explanation:

Given the height of a pumpkin t seconds after it is launched from a catapult modelled by the equation

f(t)=-16t²+32t... (1)

The pumpkin reaches its maximum height when the velocity is zero.

Velocity = {d(f(x)}/dt = -32t+32

Since v = 0m/s (at maximum height)

-32t+32 = 0

-32t = -32

t = -32/-32

t = 1sec

The pumpkin reaches its maximum height after 1second.

Maximum height of the pumpkin is gotten by substituting t = 1sec into equation (1)

f(1) = -16(1)²+32(1)

f(1) = -16+32

f(1) = 16m

The maximum height of the pumpkin is 16m
