Answer:
D
Step-by-step explanation:
Volume = lwh
120 = l(4)(3)
l = 10 feet
<h2><em>The range and mid-range are equal</em></h2><h2><em>the range is 75-25=50
</em></h2><h2><em>
the mid-range is (75+25)/2 = 100/2 = 50
</em></h2><h2><em>
50 = 50</em></h2><h2><em> HOPE IT HELPS (◕‿◕✿) </em></h2><h2><em> SMILE!!</em></h2>
1. Observe that the f(t) is change by 4 per time t => there's a acceleration of 4 => f''(t) = 4; Take the derivative of it we can get a velocity function. f'(t) = 4t + c. Since the velocity from 100 to 80 is -20 (average), this means at t = 0, f'(0) = -22 => f'(t) = 4t - 22; Take the derivative again to get the position function: f(t) = 2t^2 - 22t + d, here d = 100 should be trivial. So, the function that models the relationship is f(t) = 2t^2 - 22t + 100.
2. By the compound interest formula:
A = P (1 + r/n)^(nt) , since it's yearly, so n = 1;
results A(t) = 100 (1+0.12)^t.
3. The average rate of change is basically finding the slope, m = y1 - y2 / x1 - x2.
12+ 9.6+ 7.2=28.8 miles is the perimeter
28.8
