Show that: (p¼- q¼)(p¼ + q¼)(√P+√q)= p-q.​
Irina18 [472]

Answer:

Step-by-step explanation:

let p¼ = a, q¼ = b

L.H.S. = (a - b)(a + b)(a² + b²) = (a² - b²)(a² + b²) = (a²)² - (b²)² = p - q = R.H.S.

A certain forest covers an area of 4600km. Suppose that each year this area decreases by 7.75%. What will the area be after 13 y
wolverine [178]

Answer:

1679.60\ km^2

Step-by-step explanation:

-We can use the exponential decay function to estimate the size after 13 years:

P_t=P_oe^{-rt}

Where:

P_t is the size after t years, t is the time, r is the rate of decay and P_o the original size.

#We substitute and calculate as:

P_t=P_oe^{-rt}\\\\=4600e^{-13\times 0.0775}\\\\=1679.60

Hence, the forest covers 1679.60\ km^2 after 13 years.
