Answer:

Not proportional.

Step-by-step explanation:

Let x represent number of hours and y represent total cost.

We have been given that the vista Marina rents boats for $25 per hour. In addition to the rental fee, there is a $12 charge for fuel.

The cost of rental for x hours would be 25x.

The total cost of rental for x hours and fuel would be 25x+12.

The equation y=25x+12 total cost of x hours.

We know that two proportional quantities are in form y=kx, where k is constant of proportionality.

We can see that our equation is in form y=kx+c as it includes a constant 12.

Therefore, the number of hours for renting a boat is not proportional to the cost.

Help pls i don’t get it

Answer:

A = 22.5 m²

Step-by-step explanation:

longest side length

b = √((-7 + 4)² + (-1 - 8)²) = √90

other sides

a = √((-1 + 7)² + (2 + 1)²) = √45

height

h = √((√45)² - (½√90)²) = √22.5

Area of triangle

A = ½bh = ½√90√22.5 = 22.5 m²

a little math shows that this triangle is a tilted half of a square with sides √45
