Given:
The initial population = 750,000
23% of the population becomes a zombie everyday.
To find:
The function that represents p, the number of unaffected people after x days.
Solution:
The general exponential decay function is:
...(i)
Where, is the initial population, r is the rate of decay and x is the time period.
We know that,
The initial number of unaffected people = 750,000
The unaffected people decreasing by 23% . The decimal form of 23% is 0.23.
Putting in (i), we get
Therefore, the required function is , where p is the number of unaffected people after x days.
I say the answer is C 2*X=8 8+4=12
The radii of the frustrum bases is 12
Step-by-step explanation:
In the figure attached below, ABC represents the cone cross-section while the BCDE represents frustum cross-section
As given in the figure radius and height of the cone are 9 and 12 respectively
Similarly, the height of the frustum is 4
Hence the height of the complete cone= 4+12= 16 (height of frustum+ height of cone)
We can see that ΔABC is similar to ΔADE
Using the similarity theorem
AC/AE=BC/DE
Substituting the values
12/16=9/DE
∴ DE= 16*9/12= 12
Hence the radii of the frustum is 12
Answer:
135 ft^2
Step-by-step explanation:
50% more than 10 feet is 15 feet; 50% more than 6 feet is 9 feet.
Thus, the area of the new rectangle is 15 times 9 feet squared, or 135 ft^2.
Answer:
the answer is 2.89
Step-by-step explanation:
u divide 289 to 100 or 289/100=2.89
hope this helps
