Which table does not represent a proportional relationship? A 2-column table with 3 rows. Column 1 is labeled x with entries 9,
MrMuchimi

Answer:

the one with 12, 18, 22

Step-by-step explanation:

in the first one, 9-3=6 and 6-3=3 so -3 is the constant of the proportionality

in the second one 3-1=2, 2-1=1 so here the constant of proprtionality is -1

in the third one 16+2=18, 18+2=20 so the constant of proportionality is 2

fourth one 4 + 0.5= 4.5 and 4.5+0.5= 5, constant of proportionality is 0.5

fifth one 12+6=18, but 18+6=24

and the rest are all proportional

A ball is thrown vertically upward. After seconds, its height (in feet) is given by the function 56t - 16t^2 . What is the maxim
mr Goodwill [35]

Answer:

Therefore the maximum height that the reach is 49 feet after 1.75 seconds.

Step-by-step explanation:

Given that,

A ball is thrown vertically upward. After t seconds its height is given by the function

h=56t-16 t^2

where h is height in feet.

Maximum value:

Given function f(x)= at²+bt+c.

  1. Find the value -\frac{b}{2a}
  2. Putting x= -\frac{b}{2a} in the given function.
  3. The maximum value of the given function is f(-\frac{b}{2a}).

Here a= -16 ,  b=56 and c=0

The ball attains its maximum height when t=-\frac{56}{2.(-16)}=1.75 s.

Putting the value of t in the given function

h=(56\times 1.75)-16(1.75)^2

  =49 feet

Therefore the maximum height that the reach is 49 feet after 1.75 seconds.

Need help and will be giving Brainliest
Katena32 [7]

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

Step-by-step explanation:

hope it helps
