Physics students drop a ball from the top of a 100 foot high building and model its height above the ground as a function of time with the equation 2 ht . The height, h, is measures in feet and time, t, is 100 16 t measured in seconds. Be careful with all calculations in this problems and remember to do the exponent (squaring) first.

Complete question :
Physics students drop a ball from the top of a 100 foot high building and model its height as a function time with the equation h(t) = 100 - 16t^2.The height, h, is measured in feet and time, t, is measured is seconds.
Find the value of h(0). Include proper units. What does this output represent?
Answer:
Kindly check explanation
Step-by-step explanation:
The model given :
Height, h as a function of time :
h(t) = 100 - 16t^2
To find h(0): substitute 0 for t in the model defined ;
h(0) = 100 - 16(0)²
h(0) = 100 - 0
h(0) = 100
The output gives the height at which the ball was before it was dropped, it depicts the height when the travel time of the ball is 0

Step-by-step explanation:
To draw the plan of the class foundation using a scale of 5m to 4cm, you'll need to create a scaled-down representation of the room, including the door and windows. Here are the steps to draw the plan:
1. Determine the size of your drawing area. Since the scale is 5m to 4cm, you need to calculate the dimensions of your drawing area.
Length of the class: 20m
Breadth of the class: 10m
Using the scale, for every 5 meters in reality, you will represent it as 4 centimeters in your drawing. So, you'll need a drawing area that can accommodate these dimensions, and the scale conversion.
Length of drawing area = (20m / 5m) * 4cm = 16cm
Breadth of drawing area = (10m / 5m) * 4cm = 8cm
Therefore, your drawing area should be approximately 16cm by 8cm.
2. Draw the outline of the class: Using a ruler and a pencil, draw a rectangle with dimensions 16cm by 8cm to represent the classroom. This rectangle represents the foundation of the class.
3. Draw the door: The door is 8 meters long and 4 meters wide. Using your scale, you'll represent it as 4cm by 2cm in your drawing. Draw a rectangle within the classroom rectangle to represent the door. The top edge of the door should align with one of the longer sides of the classroom.
4. Draw the windows: The windows are 5 meters long and 3 meters wide. Using your scale, you'll represent each window as 4cm by 2.4cm in your drawing. Place the windows where they would be on the classroom walls, leaving space between them and the door.
5. Label the drawing: You can label the door and windows to indicate their dimensions if needed.

(n+2)! is equal to (n+2)*(n+1)*n*(n-1)*(n-2)...*3*2*1, using the same definition. This thus is equal to (n+1)!*(n+2), so we have:
(n+1)!/(n+1)!(n+2), or:
1/(n+2)
This is our final simplification.
What does 242,000 represent?
The present value of the house
The value of the house after x years
The increase in the value of the house each year
The increase in the value of the house after x years
Answers
Answer: The present value of the house
Step-by-step explanation:
Given: The following function represents the value of a house, in dollars, after x years:
When we substitute x=0 in the above equation, we get
Since at x=0, the function represent the initial value of a function.
Therefore, 242,000 represents the value of house in 0 years i.e. it represents the present value of the house.
