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:
Looking at the equation, k=23 is our constant of proportionality because 23 is the constant number we multiply x by.

GIVEN: Josiah is playing a computer game that lets him customize a story There are 
different eras and 
location to choose from.
TO FIND: How many different stories can Josiah construct.
SOLUTION:
Total different eras 
Total different locations 
He can choose one era and one location.
Total different stories that Josiah can construct 
Hence Josiah can construct 10 different stories.
