You must make 4 deliveries per hour with Plan A to earn as much as Plan B.
Step-by-step explanation:
Plan A;
Earning per hour = $5
Per delivery earning = $0.75
Let,
x be the number of deliveries.
A(x) = 5 + 0.75x
Plan B;
Earning per hour = $7
Per delivery earning = $0.25
B(x) = 7 + 0.25x
For earning as much as B.
A(x) = B(x)
Multiplying both sides by 0.5
You must make 4 deliveries per hour with Plan A to earn as much as Plan B.

Answer:
48,558
Step-by-step explanation:
The function which models the relationship between the elapsed time, t in years, since 2010 and the town's population, P(t), is given as:
Now, 2020-2010=10 Years
Therefore we are required to calculate the population of the town 10 years after.
To do this, we simply substitute t=10 in the function.
According to the model, the population in Fall River will be 48,558 in the Year 2020.
Answer:
Not a right triangle.
Step-by-step explanation:
If this triangle is a right triangle, then the Pythagorean theorem would work on it. According to the Pythagorean theorem, , so c would always be greater than a or b. In this scenario, the greatest number here is 18, so c = 18. Since a or b don't matter if given both legs, we have the following equation that may or may not be equal:
. We know 8 squared is 64, and 11 squared is 121, and 18 squared is 324. This means that
according to the Pythagorean theorem, and since 64 + 121 = 185, and 185 does not equal 324, the Pythagorean theorem does not work and the triangle is not a right triangle.
