2 is in the hundreds thousands place
Answer: 9 seconds
Step-by-step explanation:
When the object hit the ground,
Height h = 0
Therefore,
h(x)= -5(x+1)(x-9) = 0
0 = -5(x+1)(x-9)
Open the bracket
0 = (-5x - 5)( x - 9)
0 = -5x^2 + 45x - 5x + 45
0 = -5x^2 + 40x + 45
Divide all by -5
0 = x^2 - 8x - 9
Factorizing the equation gives
(x + 1)(x- 9)
x = -1 or 9
Since Time can't be negative
Therefore, the time seconds after launch the object will hit the ground is 9 seconds
D. 2 radians
Remember that: Radian=arc length/radius
In your case you have
arc length=2r
radius=r
so Radian=2r/r=2
Answer:
Step-by-step explanation:
See attachment.
The change from x to (x-4) moved the function to the right by 4. The - 5 moved it down by 5 (as measured from the crossover/inflection point.
Each person payed $8 because $24 divided amongst 3 people is $8 per person.
