1. Contaminated water is subjected to a cleaning process. The concentration of the pollutants is initially 5 mg per liter of wat

er. If the cleaning process can reduce the pollutant by 10% each hour, define a function that can represent the concentration of pollutants in the water in terms of the number of hours that the cleaning process has taken place.​

Answer:

C(t)=5\cdot(0.9)^t

Step-by-step explanation:

Ang exponential function ay karaniwang ginagamit para ilarawan ang natural na pagtaas o pagbaba ng mga proseso, kung saan ang pagbabago ay proporsyonal sa kasalukuyang halaga.

Ang isang exponential decaying function ay ipinapahayag bilang:

C(t)=C_o\cdot(1-r)^t

Saan:

C(t) ang aktwal na halaga ng function sa oras na t

Co ang paunang halaga ng C sa t=0

r ang rate ng pag-alis, na ipinahayag sa decimal

Ang konsentrasyon ng pollutants ay nagsisimula sa Co=5 mg/lt. Alam din natin na ang pollutant ay bumababa ng 10% ng konsentrasyon nito bawat oras. Kaya't ito ay nagbibigay ng r = 10% / 100 = 0.1

Pagpapalit sa pangkalahatang equation:

C(t)=5\cdot(1-0.1)^t

Pagsasagawa:

\boxed{C(t)=5\cdot(0.9)^t}

What are the eight-digit grid coordinates for benchmark 86 (circled in red)?
lawyer [4039]

Answer:

An eight-digit grid coordinate allows for precision within 10 meters.

Step-by-step explanation:

Grid coordinates are designed to direct accurately to a specific location by using a map that includes equally spaced vertical and horizontal lines, each assigned numbers to outline a place. The intersection of these vertical and horizontal lines has unique identifiers and creates small sections called grid squares.

The precision increases with the number of digits in the coordinate; an eight-digit designation gives accuracy to the nearest 10 meters.

If the area of the vegetable garden is 170 square feet which equation could be of use to find the length of the tomato patch? 0=
Svet_ta [4341]

Answer:

The equation 0 = 3x² + 17x - 160 might be useful in determining the length.

Step-by-step explanation:

The area of the vegetable garden is specified as 170 ft².

Now, regarding the provided equations;

1) For 0 = 3x² + 2x + 180, applying the quadratic formula results in:

x = [-2 ± √(3² - 4(3 × 180)]/(2 × 3)

x = [-2 ± √(-2151)]/6

The square root value is negative, indicating no real solution for x.

Thus, this equation does not help find the length.

2) For the equation 0 = 3x² + 10x + 180, employing the quadratic formula, the square root value is also negative, hence there's no natural root for x. This means this equation can't be used to determine the length.

3) For 0 = 3x² + 17x - 160, the roots when using the quadratic formula yield -10.67 or 5. The value 5 is viable since it is a whole number. Considering the area is also a whole number, this equation can be applied to ascertain the length.

4) For 0 = 3x² - 160, simplifying gives;

3x² = 160

x² = 160/3

x = ±√(160/3)

x = ±7.303

Since the area is a whole number but this length isn't, this equation may not accurately determine the length.

On her birthday, Sonia distributed chocolates in an orphanage. She gave 5 chocolates to each child and 20 chocolates to adults.
Svet_ta [4341]

Answer with explanation:

Total number of children = x

Total chocolates shared = y

In total, the chocolates distributed to the children equals 5 times the number of children, or 5 x.

Chocolates received by adults equal 20.

Let the number of adults be z.

Expressing this situation as an equation:

y = 5 x + 20 z

z=\frac{y-5 x}{20}

⇒Number of adults = z

       =\frac{y-5 x}{20}

The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used
babunello [3666]
Let x = 6.2
Define y as half of x: y = 0.5x
Calculate y: y = 0.5 × 6.2 = 3.1
Calculate z by subtracting x and y from 14.5: z = 14.5 - 6.2 - 3.1 = 5.2
Each variable corresponds to a triangle side
