H=-16t^2+46t+6 after how many seconds will the ball hit the ground?
ANEK [815]
Ball hit the ground is when the function equals zero
0=-16t^2+46t+6
we can't factor so use quadraticformula

for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-46+/- \sqrt{46^2-4(-16)(6)} }{2(-16)}
x=\frac{-46+/- \sqrt{2116+384} }{-32}
x=\frac{-46+/- \sqrt{2500} }{-32}
x=\frac{-46+/- 50 }{-32}
x=\frac{-46+ 50 }{-32} or \frac{-46- 50 }{-32}
x=\frac{4}{-32} or x=\frac{-96}{-32}
x=-1/6 or x=3

we cannot have negative time because time starts at 0
disregard -1/6 as a possible answer


answer is after 3 seconds

Find all polar coordinates of point p where p = ordered pair 5 comma pi divided by 3.
Aleonysh [2.5K]

Find all polar coordinates of point p where p = ordered pair 5 comma pi divided by 3.

The polar coordinate of any point can be written as:

<span>(r, θ) = (r, θ + 2nπ)                                           --> when positive</span>

<span> (r, θ) = [ - r, θ + (2n + 1)π ]                           --> when negative</span>

<span> where n is any integer.</span>

The polar coordinates of this given point P is: P = (r, θ) = (5, π/3).

When the value of r is positive, the polar coordinate is written as P= (5, π/3) = (5, π/3 + 2nπ)

where n is any integer.

When the value of r is negative, the polar coordinate is written as P = (5, π/3) = [ - 5, π/3 + (2n + 1)π] where n is any integer.

 

Therefore all polar coordinates of point P are (5, π/3 + 2nπ) and [ - 5, π/3 + (2n + 1)π ].
