Answer:
Option C.
Step-by-step explanation:
If a line passes through two points and , then the equation of line is
The line passes through the points (1,0) and (0,-2). So, the equation of line is
It is a solid line and the shaded region lies below the line, so the sign of inequality must be "≤".
First inequality is .
The parabola intersect the x-axis at 0 and 3, so the equation of of parabola is
It is a solid curve and the shaded region lies above the curve, so the sign of inequality must be "≥".
Second inequality is .
Therefore, the correct option is C.
Answer:
70.4 meters
Step-by-step explanation:
A to B: 40²+10²=c² = 1600+100=c² = 1700=c² = c=√1700 = 41.23
B to C: 25²+15²=c² = 625+225=c² = 850=c² = c=√850 = 29.15
41.23+29.15=70.38
Answer:
Average rate of change = 0.4
Step-by-step explanation:
Average rate of change of a function in the interval [a, b] is defined by the formula,
Rate of change =
From the table attached,
Rate of change of the function in the interval 20 ≤ x ≤ 40 will be
=
=
=
=
= 0.4
Therefore, average rate change of the function in the given interval 20 ≤ x ≤ 40 is = 0.4
