Answer:
f(x)=(3x-5)(4x+2) is a quardatic function.
Step-by-step explanation:
f(x)=(3x-5)(4x+2)
simplify
f(x)=3x(4x+2)-5(4x+2)
f(x)=
adding the coefficients of x, we get
f(x)=
which is quardatic equation since it contains the terms 12

Answer:
Step-by-step explanation:
In order to determine if James and Paco earn different amounts of money per hour, you must find how much money they make in one hour.
James:
James makes $35.40 in 3 hours. So, in 1 hour, he would make 35.40/3 = 11.8.
James makes $11.80 an hour.
Therefore, his equation would be d = 11.8h
Paco:
Paco makes $24.00 in 2 hours. So, in 1 hour, he would make 24/2 = 12.
Paco makes $12.00 an hour.
Therefore, his equation would be d = 12h
Hence, Paco and James make different amounts of money. Paco makes 20 cents, or $0.20, more than James.
This question is incomplete, the complete question is;
In an interval whose length is z seconds, a body moves (32z + 2z²) ft.
What is the average speed v of the body in this interval?
Answer: the average speed v of the body in this interval is 32 + 2z ft/s
Step-by-step explanation:
Given that;
Length of travel = z seconds
also the body moves (32z + 2z²) ft
i.e
distance travelled = (32z + 2z²) ft
average speed v of the body in this interval = ?
Now to get the Average Speed
we simply say;
Average Speed V = (32z + 2z²) / z
Average Speed V = 32 + 2z ft/s
Therefore the average speed v of the body in this interval is 32 + 2z ft/s
