Answer:

≈ 22 cm

Step-by-step explanation:

the circumference (C) of a circle ( the perimeter ) is calculated as

C = 2πr ( r is the radius )

   = 2π × 7 = 14π

since divided into 2 equal parts then

\frac{1}{2} C = 14π ÷ 2 = 7π ≈ 22 cm ( to the nearest whole number )

12. Dominic drives a taxi. He charges a $2 flat fee plus $1.50 per mile.
r-ruslan [8.4K]

Answer:

The y-intercept represents the flat fee.

Step-by-step explanation:

The y-intercept on the graph would be the point at which the line cuts across or intercepts the y-axis. At this point, the value of x (miles travelled) would be 0. The y-intercept in this case, would be the flat fee which is given as $2.

At x = 0, f(0) = 2.

The y-intercept represents the flat fee on the graph of f(x).
