Step-by-step explanation:
Since, K is the midpoint of JL.

I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
there are .001 meters in 1 millimeter
Answer:
v=520 -10t
Step-by-step explanation:
the rate of decrease is given a variable to calculate the rate of change. v is represented by 520 - the number of minutes.
Answer: 1.4 seconds
<u>Step-by-step explanation:</u>
The equation is: h(t) = at² + v₀t + h₀ where
- a is the acceleration (in this case it is gravity)
- v₀ is the initial velocity
- h₀ is the initial height
Given:
- a = -9.81 (if it wasn't given in your textbook, you can look it up)
- v₀ = 12
- h₀ = 3
Since we are trying to find out when it lands on the ground, h(t) = 0
EQUATION: 0 = 9.81t² + 12t + 3
Use the quadratic equation to find the x-intercepts
a=-9.81, b=12, c=3

Note: Negative time (-0.2) is not valid
