The given question have mistake. The correct question is written below.
Question:
A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?
Answer:
Option B:
Solution:
<u>General formula for the height of the projectile over time:</u>
(1) 
Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)
(2) 
Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)
Given initial velocity = 6.37 s and initial height is 0.
The height of the dog is in meters.
So, use second formula and substitute v = 6.37 and s = 0.
Hence option B is the correct answer.
X=10 because 76-26=50 and 50/5=10, z=104 because 180-76=104
Answer:
d
Step-by-step explanation:
In order to calculate the length of highest piece, You need to calculate the Greatest common divisor of 672 & 960 which is 96
So, the length of highest piece would be 96 cm
Now, Number of pieces of Iron-sheet = 672 / 96 = 7
Number of pieces of Copper-sheet = 960 / 96 = 10

Answer:
During the first year he had an annual interest of 12%, and in the second year of 25%
Step-by-step explanation:
To calculate the interest of the first year:
(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year
(300/336) - 1 = 0.12 = 12%
To calculate the interest of the second year:
(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year
(336/420) - 1 = 0.25 = 25%
