<span>Paul is not correct. A good understanding of place value is important to solve this problem. From the left, you look at the ones, tens, hundreds, and thousands for place value. In the number 6367, one 6 is in the tens column and the other 6 is in the thousands column. This means that one six is 100 times as great as the other 6. If it was 10 times as great, it would be in the hundreds column.</span>
1 foot per second and the distance between them after five seconds is 5 feet
Answer:
$1781.53
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
Principle amount <em>P </em>= 1500
Rate <em>r</em> = 0.035
Years <em>n</em> = 5
Step 2: Substitute and Evaluate for A
A = 1500(1 + 0.035)⁵
A = 1500(1.035)⁵
A = 1500(1.18769)
A = 1781.53
The rate a which the surface area, S, decreases is
The surface area is
S = 4πr²
where r = the radius at time t.
Therefore
When r = 3 cm, obtain
![\frac{dr}{dt}]_{r=3} = - \frac{1}{3} \, cm/s](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdr%7D%7Bdt%7D%5D_%7Br%3D3%7D%20%3D%20-%20%5Cfrac%7B1%7D%7B3%7D%20%5C%2C%20cm%2Fs%20%20)
Answer: -1/3 cm/s (or -0.333 cm/s)
