Answer:
4.4 ft/s
Step-by-step explanation:
Height = 15ft
Rate= 5 ft/s
Distance from the man to the kite= 32ft
dh/dt = 5 ft/s
h = √32^2 - 15^2
h = √ 1025 - 225
h = √800
h = 28.28ft
D = √15^2 + h^2
dD/dt = 1/2(15^2 + h^2)^-1/2 (2h) dh/dt
= h(225 + h^2)^-1/2 dh/dt
= (h / √225 + h^2)5
= (28.28 / √225 + 28.28^2)5
= (28.28 / √1024.7584)5
= (28.28/32)5
= 0.88*5
= 4.4 ft/s
The population of Leavetown after 100 years would be 111,17.5681.
Step-by-step explanation:
Given that,
Initial Population = I = 123,000
Decreasing Rate = r = 2.375 = 0.02375
We have to find the population after 100 years. So,
n = 100
The formula to calculate the population (P) after n years with a decreasing rate r is:
Now, put the values in this formula.
Hence, the population of Leavetown after 100 years would be 111,17.5681.
Answer:
a=4/3
Step-by-step explanation:
Opening the brackets,
a+4-12+a+2+a+2
3a=4
∴a=4/3
