Answer:

Step-by-step explanation:
Starting with :
m g + r g = 2 H
extract "g" as a common factor on the left of the equal sign:
g (m + r) = 2 H
Now, in order to solve for "g" , divide both sides of the equal sign by the binomial (m + r):
g = (2 H )/(m + r)

0.96 or 19/20
0.96 as fraction = 96/100 = 19.2 / 20 5 into 96 is 19.2 and 5 into 100 is 20
So 0.96 is the same as 19.2/20
Since 19.2 / 20 and 19 / 20 have the same denominator, therefore the 19.2 / 20 is bigger than 19 / 20.
So the 0.96 is bigger than the 19 / 20.
So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
Hope this helps!
Answer:
a)
b)d(t)=500t
c)
Step-by-step explanation:
d = Horizontal distance
s = the distance between the plane and the radar station
The horizontal distance (d), the one mile altitude, and s form a right triangle.
So, use Pythagoras theorem


a) 
(b) Express d as a function of the time t (in hours) that the plane has flown.

d(t)=500t
(c) Use composition to express s as a function of t.
