Answer:
-1
Step-by-step explanation:
Given the equation:

Substitute
into this equation:

Subtract 4:

Answer: From what you wrote the I think the ball is drop
At time 0 you are 7 meters above ground
You basically just need to solve for
1.5 =7t-4.9t^2
by rearrange the equation you get
4.9t^2-7t+1.5=0
by using Quadratic Formula
t=1.166s
X=30
-75/-50=1.5 20x1.5=30
Answer:
78.5 cm
Step-by-step explanation:
The area of a circle is represented by A = πr². Since we are replacing the value of pi(π) with 3.14, and the diameter is 10, meaning the radius(r) is 5, we can plug both values into the equation, to get A = 3.14(5^2). This simplifies to 78.5.
It's probably in my answer is 1000/200 then you should get the right answer hopefully so basically 1000/200 then it should be 5
