x is greater than or equal to 2
Answer:
2932.4
Step-by-step explanation:
Plug h = 3 and g = 27 into the expression:
Answer: 918
Step-by-step explanation:
add 220+245+215+85 together and you get $765 and you multiply this with the 1.20 to get your solution/answer Plz rate and <3
To solve you need to set the equation equal to 6 (the height at which the player caught the ball.
6 = -16t^2 + 70t + 4
Next put the equation in standard form by subtracting 6 from both sides
-16t^2 + 70t - 2 = 0
This equation can be simplified by dividing by 2
-8t^2 + 35t - 1 = 0
This equation cannot be factored, but we can use the quadratic formula to find a value for x. Using the equation above we can find the values for a=-8, b = 35 and c = -1.
using the quadratic formula we can solve for x
-b +/- sqrt(b^2 - 4ac)

The solutions are
0.03 and 4.35. as 0.03 seems an unrealistic time to hit and catch a baseball we would expect the time to be 4.35 seconds.
