Answer:

6138

Step-by-step explanation:

First, we have to find the population of the city in 2015

6% = 0.06

193,000 times 0.06 = 11580 people increase

We know it is increasing, so we have to add them

193,000 + 11580 = 204580 people in 2015

Now let's find the 3% decrease

3% = 0.03

204580 times 0.03 = 6137.4

So, about 6138 people decrease from 2015 to 2020

The value of 4 to the 3rd power =64

According to the power rule of exponents,

am = m times a x a x a

Thus, 43 can be written as 4 × 4 × 4 = 64.

Thus, the value of 4 to the 3rd power i.e., 4^3 is 64

Exponent is the process of representing huge numbers as powers, according to the definition. Exponent, then, is the number of times a number has been multiplied by itself. Using 6 as an example, multiply it by itself four times, or 6 6 6 6. You can write this as 64. In this case, the exponent is 4 and the base is 6.

f(x) = 20x4 + x3 + 8x2 + x - 12

All potential polynomial roots are represented by rational numbers, according to the Rational Root Theorem:

x = a/b

Where a is a factor of a constant term

b is the factor of coefficient of leading term

From the given polynomial:

-12 is the constant term and 20 is the coefficient of leading term

The possible factors of -12 are ±1, ±2, ±3, ±4, ±6, ±12

The possible factors of 20 are ±1, ±2, ±4, ±5, ±10, ±20

So the rational roots = (±1, ±2, ±3, ±4, ±6, ±12)/ (±1, ±2, ±4, ±5, ±10, ±20)

Solve for x when the given function is equal to zero

20x4 + x3 + 8x2 + x - 12 = 0

(4x - 3)(5x + 4)(x2 + 1) = 0

So we get:

Step-by-step explanation:

You want to know the amount Byron received from the distribution to Alyah, Byron, and Cecil, given Cecil received $40.

Let x represent the amount being distributed, and a, b, c represent the amounts received by Alyah, Byron, and Cecil, respectively.

The given relations tell us ...

  a = 1 + 1/3(x -1)

  b = 6 + 1/3(x -a -6)

  c = x -a -b = 40

Substituting for b gives us ...

  40 = x - a - (6 +1/3(x -a -6)) = x -a -6 -1/3x +1/3a +2 = 2/3x -2/3a -4

  44 = 2/3(x -a) . . . . . . . add 4, factor out 2/3

  66 = x -a . . . . . . . . . multiply by 3/2

Substituting for a gives us ...

  66 = x -(1 +1/3(x -1)) = x -1 -1/3x +1/3 = 2/3x -2/3 = 2/3(x -1)

  99 = x -1 . . . . . . . multiply by 3/2

  100 = x . . . . . . add 1

Then ...

  a = 1 + 1/3(100 -1) = 1 + 99/3 = 34

  b = 6 + 1/3(100 -34 -6) = 6 + 1/3(60) = 26

Byron received $26.

Answer:

$8.50

Step-by-step explanation:

To find Ryan's hourly rate, we need to first determine the total amount of money he made from commission. Since Ryan was paid 17% commission for all the products he sold, and he sold $1700 worth of products, he made 17/100 * $1700 = $289 in commission.

Next, we need to subtract this amount from his total pay to find the amount he was paid for working. Since Ryan was paid a total of $459, and made $289 in commission, he was paid $459 - $289 = $170 for working.

Finally, we can use this amount to calculate his hourly rate by dividing it by the number of hours he worked. Since Ryan was paid $170 for working 20 hours, his hourly rate is $170 / 20 = $8.50 per hour.

Therefore, Ryan's hourly rate is $8.50.

To find Ryan's hourly rate, we need to first calculate how much money he made from commissions. We can do this by multiplying his total sales by the commission rate: $1700 * 0.17 = $289.

Next, we need to subtract the commission from his total pay to find his base pay: $459 - $289 = $170.

Finally, we can divide his base pay by the number of hours he worked to find his hourly rate: $170 / 20 hours = $<<170/20=8.50>>8.50 per hour.

And the limit is 0 ≤ x ≤ 1/9

When we differentiate the function, then we get the value of y' as,

y' =  1/(1 - x²) × (-2x) = -2x/(1 - x²)

Now, we have to apply the values on the arc length formula, then we get,

[tex]s=\int\limits^{1/9}_0 {\sqrt{1+(\frac{-2x}{1-x^2} )^2 } } \, dx[/tex]

When we simplify this one then we get,

[tex]s=\int\limits^{1/9}_0 {\sqrt{\frac{1+x^4-2x^2+4x^2}{(1-x^2)^2} } } \, dx[/tex]

Answer:

To find out how long it will take for the police car to catch up to the speeding car, you can use the following formula:

t = d / v

Where t is the time it takes to catch up, d is the distance between the police car and the speeding car, and v is the relative speed of the police car compared to the speeding car.

In this case, the distance between the police car and the speeding car is given by the Pythagorean theorem:

d = sqrt((650 ft)^2 + (60 ft/s * 5 s)^2) = 674.22 ft

The relative speed of the police car compared to the speeding car is given by:

v = 80 ft/s - 60 ft/s = 20 ft/s

Plugging these values into the formula, we get:

t = d / v = 674.22 ft / 20 ft/s = 33.71 s

So it will take the police car approximately 33.71 seconds to catch up to the speeding car.

Note: This is just an approximation and the actual time required may vary depending on the exact positions and speeds of the two cars

Answer: it will take the police car 25 seconds and 2000 feet to catch up with the speeding car.

Step-by-step explanation: To determine the distance and time that the police car needs to catch up with the speeding car, we can set up the following system of equations:

Let x be the time it takes for the police car to catch up with the speeding car

Let y be the distance the police car needs to travel to catch up with the speeding car

The distance the speeding car travels in x seconds is given by the equation:

60x = distance

The distance the police car travels in x seconds is given by the equation:

80x = y

The distance between the two cars at the start is given by the equation:

(y - 650)^2 + 650^2 = x^2

We can solve this system of equations by substituting the second equation into the third equation, resulting in:

(80x - 650)^2 + 650^2 = x^2

Expanding and rearranging the terms, we get:

6400x^2 - 19600x + 422500 = x^2

Solving for x, we get:

x = 25 seconds

Substituting this value back into the equation for the distance the police car travels, we get:

y = 80 * 25 = 2000 ft

The group needs to sell at least 104 granola bars and any number of bottles of water in order to make a profit of at least $150.

The correct inequality is B. 1.4x + 0.75y ≥ 150. This inequality states that the group must sell at least $150 worth of items in order to make a profit. The cost of a granola bar is $1.40, and the cost of a bottle of water is $0.75. Therefore, the total cost of the items must be greater than or equal to $150. The formula for this inequality is 1.4x + 0.75y ≥ 150, where x represents the number of granola bars sold and y represents the number of bottles of water sold.

To solve this inequality, we can first multiply both sides of the inequality by 100. This will give us 140x + 75y ≥ 15000. Next, we can subtract 75y from both sides to get 140x ≥ 14250. Finally, we can divide both sides of the equation by 140 to get x ≥ 102.86. This means that the group needs to sell at least 103 granola bars in order to make a profit of at least $150. This can be further simplified by rounding up the granola bars sold to 104. Therefore, the group needs to sell at least 104 granola bars and any number of bottles of water in order to make a profit of at least $150.
