On the first day of winter, an entire field of trees starts losing its flowers. The number of locusts remaining alive in this po
Temka [501]

Answer:

Every day, there is a 49% percent the locust population.

Step-by-step explanation:

To find the daily percent change of the locust population, we just need to find N(t) for t = 0, N(t) for t = 1, then subtract the second by the first, and then divide the result by the first:

N(t) = 8950*(0.7)^2t

N(0) = 8950*(0.7)^0 = 8950*1 = 8950

N(1) = 8950*(0.7)^2 = 8950*0.49 = 4385.5

Change = N(1) - N(0) = 4564.5

Percent change = Change/N(0) = 4564.5/8950 = 0.51 = 51%

As after one day, the population decrease by 51% of the inicial population, the remaining population is 100% - 51% = 49%, so we can write:

Every day, there is a 49% percent of the locust population.

What is the length of AB?
Tresset [83]

Answer:

angle B'CA'= angle BCA..... (common angle)

angle B'A'C = angle BAC.....(corresponding angels)

therefore,

ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)

therefore,

B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)

now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9

5 / BA. = 6 / 9

therefore, 5 / BA. = 2 / 3

ba \:  =  \frac{5 \times 3}{2 }  \\  =  \frac{15}{2}  \\  = 7.5

Answer : AB = 7.5 units
