Answer:
C. 2.0 < t < 2.5
Step-by-step explanation:
Diameter of track (D) = 2 miles, Average rate (A) = 3 miles per hour
A = distance/ time
time (t) = distance/A
distance around the track (circumference) = πD = 3.142 × 2 miles = 6.284 miles
t = 6.284miles/3miles/hour = 2.1 hour
Therefore, 2.0 < t < 2.5
To determine the volume of a cylinder, you need to use the formula V = pi*r^2*h
To calculate the radius, all we have to do is divide the diameter by 2.
7.5/2 = 3.75
Now we can plug in the values.
V = 3.14 * 3.75 * 11 = 485.7 (This answer is rounded to the nearest tenth. Original answer: 485.71875)
Your answer is 485.7
Answer:
(b) Along the straight line from (0, 0, 0) to (0, 1, 1), x = 0, y = 0, dx = 0, dy = 0, while z ... 6(1)(1)}dx + {2(1)+3x(1)} + {1 – 4x(1)(19°30 = S (3x' – 6)dx=-5 ... (c) The straight line joining (0,0,0) and (1, 1, 1) is given in parametric form by x = 1, y = 1, z = 1. ... From this it follows that the line integral around any closed path in R is zero, ...

Answer:
0.75x = 23.97
Step-by-step explanation:
The total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75.
