The right answer is d. inverse variation; k=2
Inverse variation means that when increasing a variable the other decreases at the same rate or vice versa. So, we can write this statement as the following equation:
So, by plotting this equation, the result is shown in the Figure below. As you can see, this graph matches the graph above, so the conclusion is that the function has an inverse variation with k=2
Answer:
The number of miles Lori drive be 134 miles .
Step-by-step explanation:
Let us assume that the number of miles Lori be x.
As given
Lori rented a car for one day.
The daily rental rate was $12.50 plus 25 cents per mile.
As 1 dollar = 100 cent
As given
The total cost of her rental was $46.
Than the equation becomes
46 = 12.50 + 0.25x
46 - 12.50 = 0.25x
33.5 = 0.25x
x = 134 miles
Therefore the number of miles Lori drive be 134 miles .
That's the wrong right triangle to draw. Reading the problem carefully we want this one, figure attached.
So we have the usual 30/60/90 triangle but not to scale. The sides come in ratio 1:√3:2=x:100:hypotenuse. So
x = 100/√3 ≈ 57.735
We add that to our 133.2 for the total height of the Cyclone, 190.935.
Answer: 190.9
