A would be the correct answer
Answer:
square
Step-by-step explanation:
a square is all equal sides so its symmetric any way u go
The answer is c.) 2%. Since the question is talking about false negatives, meaning the chance that the results are false, then we take a look at the 98% which represents the chance of giving an accurate result for the people who are not infected meaning for those who are positive. Thus, the answer is 2% because this is the remaining percentage if 100-98%.
Answer:
1014.73 in³/s
Step-by-step explanation:
We know the volume of a cylinder, V = πr²h where r = radius of cylinder and h = height of cylinder.
Now, to find the rate of change of volume, we differentiate it with respect to time. So
dV/dt = d(πr²h)/dt
= πhdr²/dr × dr/dt + πr²dh/dh × dh/dt
= 2πrh × dr/dt + πr² × dh/dt
when r = 17 in, dr/dt = rate of change of radius = + 7 in/s, h = 5 in and dh/dt = rate of change of height = - 3in/s (negative since it is decreasing).
So, dV/dt = 2πrh × dr/dt + πr² × dh/dt
= 2π × 17 in × 5 in × (+ 7 in/s) + π(17 in)² × (- 3 in/s)
= 1190π - 867π
= 323π in³/s
= 1014.73 in³/s
Answer:
3 31/36
Step-by-step explanation:
11 1/9 = 100/9
7 1/4 = 29/4
100/9 = 400/36
29/4 = 261/36
400/36 - 261/36 = 139/36
139/36 = 3 31/36
