The graph represents a linear function, because the graph is a line.
Linear basically means straight line. If you look at the line, it always goes left once and up once and this is always the same. This means the graph follows the equation of y = mx + c and so is linear. In this case, the equation is y = -x + 1
Answer:
Step-by-step explanation:
Distance traveled by Mike in 12 hours = 4 * 12 = 48 km
This will become the radius of the circle
r = 48 km
Area of the circle to be searched = πr²
= 3.14 * 48 * 48
= 7234.56 square km
Answer:
1 - 5i
Step-by-step explanation:
(-2 + 4i) + ( 3 -9i) = -2 + 4i + 3 - 9i
= -2 + 3 + 4i - 9i
= 1 - 5i
Divide the distance by the average speed to find the time. 30 miles 20.04 mph 1.497 hrs. So it would take about 1.5 hours.
