Answer:

Either the fraction 81/4 or the decimal number 20.25 (which is equivalent to that fraction). The answer format will depend on what your teacher wants.

Step-by-step explanation:

The x coefficient is -9. When you cut that in half you get -9/2. Squaring this fraction leads to (-9/2)^2 = 81/4 = 20.25

using the midpoint formula find the coordinates of the midpoint 9f each sigment with end points (4,2),(-5,-1)

exis [7]

Answer:

The midpoint of the segment is (-0.5,0.5).

Step-by-step explanation:

Midpoint of a segment:

The midpoint of a segment is given by the mean of its coordinates.

Segment with end points (4,2),(-5,-1)

x-coordinates: 4 and -5

y-coordinates: 2 and -1

x-coordinate of the midpoint:

$x = \frac{4-5}{2} = -\frac{1}{2} = -0.5$

y-coordinate of the midpoint:

$y = \frac{2-1}{2} = \frac{1}{2} = 0.5$

The midpoint of the segment is (-0.5,0.5).

If a ball is dropped from a height of 18 feet, the function f(x) = 18(0.75)* gives the height

NeTakaya

Answer:

<h2>At the 7th bounce, the ball reached 2.3 feet height.</h2>

Step-by-step explanation:

The given expression is

$f(x)=18(0.75)^{x}$

This exponential function represents the movement of a bouncing ball after being dropped.

$x$ represents the bounce number.

So, at 7th bounce means $x=7$ , replacing this value in the function, we have

$f(7)=18(0.75)^{7}=18(0.13) \approx 2.34$

Therefore, at the 7th bounce, the ball reached 2.3 feet height.
