Answer:

Step-by-step explanation:
<u>Vertical Throw</u>
It refers to a situation where an object is thrown verticaly upwards with some inicial speed v_o and let in free air (no friction) until it completes its movement up and finally returns to the very same point of lauch. The only acting force is gravity
The projectile formula is given as

where t is time in seconds, h is the height in feet and v is the speed in ft/sec
We are required to find the time t where h=120 ft, knowing 

Rearranging

This is a second-degree equation which will be solved with the formula



Two solutions are obtained

Both solutions are possible because the ball actually is at 120 ft in its way up and then when going down
Answer:
They are both x units away from the y-axis.
Step-by-step explanation:
The x coordinates are x and -x so they are both x units away from the y-axis. The total distance between the 2 points is x -(-x) = 2x units.
no it is not correct. 18 divided by the sum of 3 and 3 equals 18 ÷ (3+3)
"sum of 3 and 3 " means 3+3 therefore 8/(3x3) = 8/9 and is completely different from the equation desired to be represented.
Answer:
12 inches
Step-by-step explanation:
Set up an equation:
Variable x = height of the scale model
3/18 = x/72
Cross multiply:
3 × 72 = 18 × x
216 = 18x
Divide both sides by 18:
12
Answer:
4
Step-by-step explanation:
The sides of a parallelogram are parallel, which means 25x and 100 are alternate angles and therefore equal.
25x=100
x=4
