Answer:
3. 14 cm
Step-by-step explanation:
Solve for radius first using the equation for circumference:
C = 2πr
44 = 2πr
44/2π = r
r = about 7 cm
d = 2r
d = 2*7
= 14 cm
The perimeter (62 cm) is twice the length plus twice the width.
The length plus twice the width is given as 42 cm. The difference between these sums is the length, 20 cm.
There are three students. The student in front has 2 students behind them, the student in the back has 2 students in front of them, and there is a student in the middle.
Answer:
7, -3/4, -3
Step-by-step explanation:
Note that all three of the given functions are linear. We can read the slopes directly from these functions: 7, -3/4, -3. Between any two values of x, the slope is exactly the same in each of these three functions.
Thus,
1) the average rate of change of f(x) = 7x - 4 over the interval [2,4] is 7.
2) the average rate of change of g(x) over the given interval is -3/4.
3) the average rate of change of h(x) over the given interval is -3.
