Answer:
Step-by-step explanation:
Direct variation has the form y=kx, given k=7 and x=20
y=7(20)=140
Answer:
Step-by-step explanation:
The continuous compound formula is
where P is the principle or starting value, r is the growth rate in decimal form, and t is the time in years. For us:
![y=3624e^{(.03)(2)}\\y=3624e^{.06}\\y=3624(1.061836547)\\y=3848.09](https://tex.z-dn.net/?f=y%3D3624e%5E%7B%28.03%29%282%29%7D%5C%5Cy%3D3624e%5E%7B.06%7D%5C%5Cy%3D3624%281.061836547%29%5C%5Cy%3D3848.09)
which would probably round to just 3848 people.
Answer:
66 cm
Step-by-step explanation:
Diameter (d) = 21 cm
![C = \pi \: d = \frac{22}{7} \times 21 = 22 \times 3 = 66 \: cm](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%20%5C%3A%20d%20%3D%20%20%5Cfrac%7B22%7D%7B7%7D%20%20%5Ctimes%2021%20%3D%2022%20%5Ctimes%203%20%3D%2066%20%5C%3A%20cm)
.70 yup that's it that's the answer
Question 1:
<h3>Answer: The number does <u>not</u> change</h3>
Removing the zero from 0.76 leads to .76 which is the same as before. Both lead to
in scientific notation.
Personally I prefer the zero up front to make the decimal point stand out easier. Of course it's just a preference, so its up to you to decide which you prefer.
===========================================
Question 2:
<h3>Answer: Yes the number changes</h3>
Taking the zero out of 10.25 leads to 1.25 which is definitely a different number (and smaller). Therefore, this zero is a significant digit compared to before.
