Answer:

Rational

Step-by-step explanation:

-1.8 is a rational number. It has a terminating and non repeating decimal.

-1.8=-\frac{18}{10} =-\frac{9}{5}

Hope this helps.

As a little bonus: -8.1 would be rational for the same reason.

-8.1=-\frac{81}{10}

Whitney kicks a football off the ground. The height, h , in feet, of the football above the ground after t seconds is given by h
malfutka [58]

Answer:

<em>after 4seconds</em>

Step-by-step explanation:

Given the height, h , in feet, of the football above the ground after t seconds expressed by h ( t ) = − 8 t^2 + 32 t, the height of the ball on the ground is 0feet.

Substitute h(t) = 0 into the expression and calculate t;

h ( t ) = − 8 t^2 + 32 t

0 = − 8 t^2 + 32 t

8t² = 32t

8t = 32

Divide both sides by 8

8t/8 = 32/8

<em>t = 4s</em>

<em>Hence the football hits the ground after 4seconds</em>

10/18 divided by 15/18= 10/18 x 18/15 = 180/270

180/270= 2/3
