Y= 6 because it is located in the same distance away from each point.
9 pieces 18 divided by 1 7/8 = 9.6 but you can’t have .6 so it’s just 9
Answer:
3.81 s
Step-by-step explanation:
Let's consider the following formula that represents the journey of a falling object.
d = 3 t + 5 t²
where,
- d is the distance measured in feet
- t is the time measured in seconds
We can find the time that it will take to travel 84 feet by replacing d = 84 in the equation.
84 = 3 t + 5 t²
5 t² + 3 t - 84 = 0
We have a = 5, b = 3 and c = -84. We apply the second grade solving formula.
![x_{1,2} = \frac{-b \pm \sqrt{b^{2}-4ac} }{2a} = \frac{-3 \pm \sqrt{3^{2}-4(5)(-84)} }{2(3)}](https://tex.z-dn.net/?f=x_%7B1%2C2%7D%20%3D%20%5Cfrac%7B-b%20%5Cpm%20%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%20%7D%7B2a%7D%20%3D%20%5Cfrac%7B-3%20%5Cpm%20%5Csqrt%7B3%5E%7B2%7D-4%285%29%28-84%29%7D%20%7D%7B2%283%29%7D)
x₁ = 3.81 and x₂ = -4.41
Since the time cannot be negative, the answer is t = 3.81 s
Answer:
![\large\boxed{x < -3.25}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%20%3C%20-3.25%7D)
Step-by-step explanation:
3 - 2x(-2) < -10
Multiply 2x(-2)
4x + 3 < -10
Subtract 3 from both sides of the equation
4x < -13
Divide both sides of the equation by 4
