Greg walks into a store at 6:30 a.m. 
The store opens at 8:00 a.m. 
How much time does Greg have until the store opens? 
8:00-6:30=. 1 hour and 30 minutes
        
             
        
        
        
 will represent this linear model shown in the data table.
  will represent this linear model shown in the data table.
<h3>What will be the linear model for the given data?</h3>
Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option 
So if we put the value x=1980 in the  then
  then


 
These values are closest to 70.1 whereas other options do not satisfy the condition. 
Thus  will represent this linear model shown in the data table.

Answer:2500mcg would be 2.5mg
Step-by-step explanation:
1000mcg = 1mg so 2500mcg = 2.5mg
 
        
             
        
        
        
Answer:
Step-by-step explanation:
In order to find the horizontal distance the ball travels, we need to know first how long it took to hit the ground. We will find that time in the y-dimension, and then use that time in the x-dimension, which is the dimension in question when we talk about horizontal distance. Here's what we know in the y-dimension:
a = -32 ft/s/s
v₀ = 0 (since the ball is being thrown straight out the window, the angle is 0 degrees, which translates to no upwards velocity at all)
Δx = -15 feet (negative because the ball lands 15 feet below the point from which it drops)
t = ?? sec. 
The equation we will use is the one for displacement:
Δx =  and filling in:

t = .968 sec (That is not the correct number of sig fig's but if I use the correct number, the answer doesn't come out to be one of the choices given. So I deviate from the rules a bit here out of necessity.)
Now we use that time in the x-dimension. Here's what we know in that dimension specifically:
a = 0 (acceleration in this dimension is always 0)
v₀ = 80 ft/sec
t = .968 sec
Δx = ?? feet
We use the equation for displacement again, and filling in what we know in this dimension:
Δx =  and of course the portion of that after the plus sign goes to 0, leaving us with simply:
 and of course the portion of that after the plus sign goes to 0, leaving us with simply:
Δx = (80)(.968)
Δx = 77.46 feet
