How to simplify 0.111111111 repeating as a fraction

Any numerical repeating pattern can be rationalized...let x=0.111 then:

10x=1.111 and upon taking differences:

10x-x=1.111-0.111

9x=1 then divide both sides by 9

x=1/9

(This method works for converting any repeating numerical pattern to a rational number)

Depending on how many times it repeats, and I used 9 1's from your question, the answer would be 1/9.

If g(x) = x3 - 5 and h(x) = 2x - 2, then h(g(-2))= ?

mixas84 [53]

Please, write "x^3" for "the cube of x," not "x3." "^" denotes exponentiation.

Then you have g(x) = x^3 - 5 and (I assume) h(x) = 2x - 2.

1) evaluate g(x) at x = -2: g(-2) = (-2)^3 - 5 = -8 - 5 = -13

2) let the input to h(x) be -13: h(-13) = 2(-13) - 2 = -28 (answer)

A projectile is launched upward from ground level with an intentional speed of 98 m/s. How high will it go? when will it return

viktelen [127]

Let h(t) represent the height of the projectile after t seconds. If the projectile is being launched from the ground, then h(0)=0, and h(t)=-4.9t²+98t. When the equation is in this form, the maximum height is determined by -98/2(-4.9), or after 10 seconds. Thus
-4.9(100)+98(10)=490 m as the highest point of the projectile
Then, when it hits the ground, h(t)=0, so
0=-4.9t²+98t
98t=4.9t²
4.9t=98
t=20
