The plane has searched 12,950 hectares. the ratio between hectares to square miles is: 1 hectare is 2.471 acres

we know that

one square mile is equal to 258.999\ hectares

so

by proportion

\frac{258.999}{1} \frac{hectares}{square\ miles} =\frac{x}{50} \frac{hectares}{square\ miles}\\\\ x=50*258.999= 12,949.95\ hectares

therefore

<u>the answer is</u>

12,950\ hectares

Thallium-210 has a half-life of 1.32 minutes. Find an equation for the percent of Thallium-210 sample that remains after t minut
Lady bird [3.3K]

Answer:

  p(t) = 100%·2^(-t/1.32)

Step-by-step explanation:

The equation for exponential decay is ...

  (remaining amount) = (initial amount)·2^(-t/(half-life))

Here, we can represent the percentage remaining by p(t) and the initial amount by 100%. Then, for a half-life of 1.32 minutes, the amount remaining is ...

  p(t) = 100%·2^(-t/1.32) . . . . . where t is in minutes

_____

Alternate functional forms are possible, such as ...

  p(t) = 100%·e^(-0.525112t)

  p(t) = 100%·0.591489^t

A carpenter is building a rectangular shed with a fixed perimeter of 54 ft. What are the dimensions of the largest shed that can
lutik1710 [3]

Answer:

the Largest shed dimension is 13.5 ft by 13.5 ft

Largest Area is 182.25 ft²

Step-by-step explanation:

Given that;

Perimeter = 54 ft

P = 2( L + B ) = 54ft

L + B = 54/2

L + B = 27 ft

B = 27 - L ------------Let this be equation 1

Area A = L × B

from equ 1, B = 27 - L

Area A = L × ( 27 - L)

A = 27L - L²

for Maxima or Minima

dA/dL = 0

27 - 2L = 0

27 = 2L

L = 13.5 ft

Now, d²A/dL² = -2 < 0

That is, area is maximum at L = 13.5 using second derivative test

B = 27 - L

we substitute vale of L

B = 27 - 13.5 = 13.5 ft

Therefore the Largest shed dimension = 13.5 ft by 13.5 ft

Largest Area = 13.5 × 13.5 = 182.25 ft²
