Answer:
The time taken for the projectile to reach the given height is 1.2 s.
Step-by-step explanation:
Given;
height of travel, h = 25 ft
initial velocity of the projectile, u = 15 ft/s
The time taken for the projectile to travel a height of 25 ft is given by the following kinematic equation;
h = ut + ¹/₂gt²
25 = 15t + ¹/₂(9.8)t²
25 = 15t + 4.9t²
4.9t² + 15t - 25 = 0
solving the quadratic equation, we will have the following solution of t;
t = 1.2 s
Therefore, the time taken for the projectile to reach the given height is 1.2 s.
Answer:
C. 4x + 1.
Step-by-step explanation:
(5x+3)-(x+2) First remove the parentheses. Remember to distribute the negative over the second one:
= 5x + 3 - x - 2 Bring like terms together:
= 5x - x + 3 - 2 Simplify like terms:
= 4x +1.
Answer:
try 1.8 or .18
Step-by-step explanation:
To find 708/100 just divide! 708 divided by 100 is 7 with a remainder. Turn the remainder which is 8 as a fraction by placing the 8 over 100. Then simplify. 8/100=4/50=2/25
Your answer is 7 and 2/25
