There is a drought and the oak tree population is decreasing at the rate of 5% per year. if the population continues to decrease at the same rate, how long will it take for the population to be half of what it is? if necessary, round your answer to the nearest tenth.

the population will reach half of its original value in approximately years.

13.5 years

Step-by-step explanation:

The multiplier of the population each year is 5% less than 1, so is 0.95. Then the population in t years is multiplied by 0.95^t. We want to find t such that this value is 1/2.

0.50 = 0.95^t

log(0.50) = t·log(0.95)

log(0.50)/log(0.95) = t ≈ 13.5134 ≈ 13.5

The population will decline to half its original value in approximately 13.5 years.

i have no idea just need points sorry

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
