Answer:
N(h) = 2h + 6
Step-by-step explanation:
A model of the number of people that Denis can invite to his party:
N(x) = x/25.............(1)
Where x = amount of money saved
Amount of money saved can be modeled by the equation:
M(h) = 50h + 150...........(2)
In the above model, h = number of overtime hours
M(h) = amount of money saved = x
Therefore equation (1) can be re - written as:
N(x) = M(h)/25.................................(3)
Substituting equation (2) into equation (3)
Find an explicit expression that models the number of people that Denis can invite to his party if he worked h overtime hours this week can be expressed as:
N(h) = 2h + 6
Answer:
See explanation and proof below.
Step-by-step explanation:
For this case we want to proof this identity:
And we need to us the double angle formula given by:
If we use a substitution for example we see that the double angle formila is given by:
And we got:
And if we apply sqaure root on both sides we got:
And that complete the proof
