10/9 =1.111..... The 1s go on forever and never end.
What you do first is add 4 to both sides of the equation to get x alone and you get x=11. X is equal to 11.
0.35294117647 so it would be 0.35
Answer: 15x² + 2x + 4
x = -2/3, 0, 1/2
Step-by-step explanation:
5x(3x + 2) - 4(2x - 1)
First, distribute:
15x² + 10x - 8x + 4
Combine like terms:
15x² + 2x + 4
This is your polynomial!
If you needed to solve for x, take your original factored polynomial and set each term equal to 0:
5x(3x + 2) - 4(2x - 1)
5x = 0
x = 0
3x + 2 = 0
3x = -2
x = -2/3
-4 = 0
No solution
2x - 1 = 0
2x = 1
x = 1/2
x = -2/3, 0, 1/2
Hope this helps!
For this case we have an equation of the form:
h (t) = (1/2) * a * t ^ 2 + vo * t + h0
Where,
a: acceleration
vo: initial speed
h0: initial height
t: time
We have then that the equations:
h (t) = - 16t ^ 2 + 19t + 110
Therefore, the initial velocity is given by:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown is:
vo = 19 feet / s
