Answer:

The mapping can also be represented as the set of ordered pairs: (4, 9) (5, 10) (6, 11) (7, 12). The ordered pair preserves the directional property of the relation. It is consistent with the order of points plotted on a Cartesian Plane represented by (",$). In the Arrow Diagram that follows.

The equation for a circle is x^2 - 8x + y^2 -8 =0. what is the equation of the circle in standard form?
yKpoI14uk [10]
You have to complete the square on this to get it into standard form of a circle.  Move the 8 over to the other side because that's part of the radius.  Group together the x terms, take half the linear term which is 8, square it and add it in to both sides.  Half of 8 is 4, 4 squared is 16, so add in 16 to both sides.  I'll show you in a sec.  You don't need to do anything to the y squared term.  This just means that the center of the circle does not move up or down, only side to side, right or left.  Here's your completing the square before we simplify it down to its perfect square binomial. ( x^{2} -8x+16)+ y^{2} =8+16.  Now break down the parenthesis into the perfect square binomial and do the addition of the right: (x-4) ^{2} + y^{2}=24.  This is the standard form of a circle that has a center of (4, 0) and a radius of \sqrt{24}

The function h is given by h ( t ) = ( 1 − t ) ( 8 + 16 t ) models the height of a ball in feet, t seconds after it is thrown.
Elena-2011 [213]

9514 1404 393

Answer:

  • zeros: t = 1, t = -1/2
  • no: the domain of the function is t ≥ 0
  • 8 feet

Step-by-step explanation:

The zeros are the values of t that make the factors zero.

  1 -t = 0   ⇒   t = 1

  8 +16t = 0   ⇒   t = -8/16 = -1/2

The equation is used to model height after the ball is thrown. We don't expect it to be a good model before the ball is thrown (t < 0), so the zero in that region is extraneous.

Only the positive zero is in the function's domain, so that is the only one that is meaningful.

__

When t = 0 (at the time the ball is thrown), the function value is ...

  h(0) = (1 -0)(8 +0) = 8

The ball is thrown from a height of 8 feet.
