1 answer:

Answer: about 54 ft." .
__________________________________________________
Explanation:
____________________
A = L * w ;

A square is a rectangle that has all equation sides;

so; for a square. (L = w).

or, "A = s² " ; in which "s" in the length of any one side.
______________
Since "A = s² "

And "A = 182 ft² " ;

we need to solve for "s" ;

and then find the perimeter of the square with is: "4*s" .
_______________________
A = s² ; ↔ s² = A ; s² = 182 ft² ;

Take positive square root of each side of the equation; to isolate "s" on one side of the equation ; and to solve for "s" ;

√(s²) = √(182 ft²) ;

to get: s = √182 ft, = 53.9629502529281659 ft.
_________________________________
The perimeter: 4* s = 4√(182 ft) = 4* (13.4907375632320415 ft.) ;
_________________________________________________
= 53.9629502529281659 ft.
__________________________________________________
round to 54 ft.

Karo-lina-s [1.5K]

Answer: Fish A: 9 inches ; Fish B: 6 inches

Step-by-step explanation:

This can be turned into a systems of equation, where x equals the length of fish A and y equals the length of fish B:

3x + 2y = 39 → -3x - 2y = -39

3x + 4y = 51 → 3x +4y = 51

Combine: 0 + 2y = 12 → y = 6 inches.

Plug back in: 3x + 2(6) = 39 → 3x = 27 → x = 9 inches.

The table gives estimates of the world population, in millions, from 1750 to 2000. year population year population 1750 790 1900

Tems11 [23]

The poopulation exponential model is given by

$P(t)=P_0e^{kt}$

Where, P(t) is the population after year t; Po is the initial population, t is the number of years from the starting year; k is the groth constant.

Given that the population in 1750 is 790 and the population in 1800 is 970, we obtain the population exponential equation as follows:

$970=790e^{50k} \\ \\ \Rightarrow e^{50k}=1.228 \\ \\ \Rightarrow 50k=\ln{1.228}=0.2053 \\ \\ \Rightarrow k=0.0041$

Thus, the exponential equation using the 1750 and the 1800 population values is $P(t)=790e^{0.0041t}$

The population of 1900 using the 1750 and the 1800 population values is given by

$P(t)=790e^{0.041\times150} \\ \\ =790e^{0.6158}=790(1.8511) \\ \\ =1,462$

The population of 1950 using the 1750 and the 1800 population values is given by

$P(t)=790e^{0.041\times200} \\ \\ =790e^{0.821}=790(2.2729) \\ \\ =1,796$

From the table, it can be seen that the actual figure is greater than the exponential model values.
