For this case we have the following expression:
We apply distributive property, which by definition establishes that:
So:
Answer:
There are two of them:
1). (n * a) means n + n + n + n + n + n + n + . . . 'a' times.
2). (n * a) also means a + a + a + a + a + a + a + a + . . . 'n' times.
Answer:
25 miles
Step-by-step explanation:
At 1 p.m. the maximum travel distance is reached. This is 25 miles.
Lets find the equation that represents that relationship:
y = zx^2
plug in data:
18 = z(6)^2
18 = z(36)
z = 1/2
then the equation is:
y = (1/2)x^2
now you just have to plot that equation
