Answer:
7.92 years
Step-by-step explanation:
We want to find t such that ...
3 = 2^(t/5)
where 2^(t/5) is the annual multiplier when doubling time is 5 years.
Taking logs, we have ...
log(3) = (t/5)log(2)
t = 5·log(3)/log(2) ≈ 7.92 . . . years
It will take about 7.92 years for the population to triple.
Figure 4 is the image of the square LMNP after the translation.
<u>Step-by-step explanation:</u>
Let us see the coordinates of the pre image LMNP as,
L (-3,1)
M(-1,1)
N(-1,-1)
P(-3,-1)
after translation of (x,y) → (x+5, y -3) the coordinates of the image obtained as,
L'(2,-2)
M'(4,-2)
N'(4,-4)
P'(2,-4) which matches the image 4.
Answer:
Option A ![V_B=19\ cm^3](https://tex.z-dn.net/?f=V_B%3D19%5C%20cm%5E3)
Step-by-step explanation:
The volume of a cone is:
![V_B = \pi\frac{hr ^ 2}{3}](https://tex.z-dn.net/?f=V_B%20%3D%20%5Cpi%5Cfrac%7Bhr%20%5E%202%7D%7B3%7D)
The volume of a cylinder is:
![V_A = \pi(r ^ 2)h](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cpi%28r%20%5E%202%29h)
Both figures have the same height h and the same radius r.
The volume of the cylinder![V_A = 18\pi\ cm ^ 3](https://tex.z-dn.net/?f=V_A%20%3D%2018%5Cpi%5C%20cm%20%5E%203)
We want to find the volume of the cone.
Then, we find r and h:
![V_A = 18\pi = \pi(r ^ 2)h](https://tex.z-dn.net/?f=V_A%20%3D%2018%5Cpi%20%3D%20%5Cpi%28r%20%5E%202%29h)
We simplify.
![V_A = 18 = (r ^ 2)h](https://tex.z-dn.net/?f=V_A%20%3D%2018%20%3D%20%28r%20%5E%202%29h)
Then the product of
.
We substitute this in the cone formula and get:
![V_B =\frac{\pi}{3}(18)\\\\V_B = \frac{18}{3}\pi\\\\V_B=19\ cm^3](https://tex.z-dn.net/?f=V_B%20%3D%5Cfrac%7B%5Cpi%7D%7B3%7D%2818%29%5C%5C%5C%5CV_B%20%3D%20%5Cfrac%7B18%7D%7B3%7D%5Cpi%5C%5C%5C%5CV_B%3D19%5C%20cm%5E3)
