Final answer:

The quotient of the polynomial division (3x³ - x² - x - 1) ÷ (x - 1) is 3x² + 2x + 1 using synthetic division.

Explanation:

To find the quotient of (3x³ - x² - x - 1) ÷ (x -1), we can use polynomial long division or synthetic division. In this case, the coefficient in front of x in the divisor (x - 1) is 1, so we can use synthetic division directly.

Set up the synthetic division by writing the coefficients of the dividend, which are 3, -1, -1, and -1, and the zero of the divisor, which in this case is +1. Carry out the synthetic division process to get the quotient.

The result of the synthetic division gives us the coefficients of the quotient, which are the coefficients for the powers of x in the quotient polynomial, starting from one degree less than the original polynomial because we are dividing by a first-degree polynomial.

The remainder, if there is one, would be the constant at the end or the remainder over the divisor.

The quotient of the polynomial division is (3x² + 2x + 1) with no remainder.

Answer:

The area of the corral is 2976 ft²

Step-by-step explanation:

Here, we have the perimeter of the rectangle given as 220 ft

Therefore, since in a rectangle, we have 2 sides of the four sides equal, that is;

Perimeter = 2×One side + 2×Other side

or Perimeter = 2×X + 2×Y

Here perimeter = 220 ft = 2×X + 2×Y

As one of the sides is 48 ft, we have;

220 ft = 2 × 48 + 2×Y

Therefore, 2×Y = 220 ft - 2×48 ft = 124 ft

∴ Y = 124 ft ÷ 2 = 62 ft

The area of the corral = Area of rectangle = Length × Width = 62 ft × 48 ft

Area of the corral = 2976 ft².

Answer:

9 fruit baskets.

Step-by-step explanation:

Given:

Steve sold 36 fruit baskets for a school fundraiser.

Evie sold 25% of the number of baskets that Steve sold.

Question asked:

How many fruit baskets did Evie sell?

Solution:

As given that Evie sold 25% of the number of baskets that Steve sold.

Number of baskets sold by Evie = 25% of 36

                                                      [tex]=\frac{25}{100}\times36\\\\ =\frac{900}{100}\\ \\=9[/tex]

Thus, 9 fruit baskets sold by Evie.

Final answer:

To solve the equation by factoring, we factor out common terms from both sides of the equation and set each factor equal to zero. We consider the factors separately and solve for θ to find the solutions.

Explanation:

To solve the given equation, we need to factorize the trigonometric terms. Let's start by factoring out the common factor of sin(θ) cot(θ) from the left side of the equation:

csc(θ) cot(θ) − sin(θ) tan(θ) = cos(θ)

sin(θ) cot(θ)(csc(θ) − tan(θ)) = cos(θ)

Now we have a product of two factors equal to zero, so we can set each factor equal to zero and solve for θ:

sin(θ) cot(θ) = 0

csc(θ) − tan(θ) = cos(θ)

To find the solutions for sin(θ) cot(θ) = 0, we can consider the factors separately:

sin(θ) = 0 or cot(θ) = 0

For sin(θ) = 0, the solutions are θ = kπ, where k is an integer.

For cot(θ) = 0, we can rewrite it as cos(θ)/sin(θ) = 0, which means cos(θ) = 0 and sin(θ) ≠ 0. The solutions for cos(θ) = 0 are θ = (2k + 1)π/2, where k is an integer.

Now let's solve csc(θ) − tan(θ) = cos(θ):

csc(θ) − (sin(θ)/cos(θ)) = cos(θ)

(1/sin(θ)) − (sin(θ)/cos(θ)) = cos(θ)

Using a common denominator, we can combine the fractions:

(cos(θ) − sin(θ))/sin(θ) = cos(θ)

Now we have a fraction equal to a constant. This can only be true if the numerator is zero:

cos(θ) − sin(θ) = 0

Using the identity cos(θ) − sin(θ) = −√2 sin(θ + π/4), we can rewrite the equation as:

−√2 sin(θ + π/4) = 0

Solving for sin(θ + π/4) = 0, we get θ + π/4 = kπ, where k is an integer.

Therefore, the solutions to the equation csc(θ) cot(θ) − sin(θ) tan(θ) = cos(θ) are:

θ = kπ (for sin(θ) cot(θ) = 0)

θ = (2k + 1)π/2 (for csc(θ) − tan(θ) = cos(θ))

The mean of the normal monthly precipitation for August in these 20 U.S. cities is obtained by adding all precipitation values and dividing by the total number of values, which gives a mean of 3.09 inches.

To find the mean of the data, we sum all the values and then divide by the number of values. After adding all the given 20 precipitation values, the total sum comes out to be 61.8 inches. So the mean of the data will be 61.8/20 = 3.09 inches. Therefore, the mean normal monthly precipitation for August in these 20 U.S. cities is 3.09 inches.

Answer:

10x^3+16

Step-by-step explanation:

Step-by-step explanation:

The concert organizers estimate people will attend if it is not raining = 19000

If its raining people will attend = 4000

On the day of the​ concert, meteorologists predict a 90​% chance of rain.

This means 10 % chance of not raining

The expected number of people = 90% (4000) + 10% (19000)

   = 360 + 1900

  = 2260

The expected number of people who will attend this concert = 2260

Answer:

125000 square feet

Step-by-step explanation:

Since there are only three sides of the rectangle, the perimeter of the fence is:

Let x and y be the sides of the rectangle, we are left with:

2 * x + y = 1000

solving for and:

y = 1000 - 2 * x

The area of the corral is:

A = x * y

replacing

A = x * (1000 - 2*x)

A = 1000 * x - 2*x^2

to find the maximum for the parabolic function A = 1000 * x - 2*x^2

The function has a maximum since the quotient before x ^ 2 is negative: -2 <0

Amax = c - b^2 /4*a

where a = -2, b = 1000, c = 0

A max = 0 - 1000^2/(4 * (- 2))

A max = 125000 ft^2

The maximum possible area of the pen is 125000 square feet.

Final answer:

125,000 square feet,

Explanation:

Let us denote the length of the rectangular area parallel to the creek as L and the width of the area as W. Given that the total amount of fencing available is 1000 feet, we can express the perimeter that Jake can fence as 2W + L = 1000 feet, since the creek forms one of the longer sides of the rectangle, and no fencing is required there.

The area A of the rectangle is given by the product of its length and width, i.e., A = L × W. Our goal is to maximize A. From the perimeter equation 2W + L = 1000, we can express L as L = 1000 - 2W.

Substituting this into the area formula, we get A = W * (1000 - 2W). This is a quadratic function and can be written as

A = -2W^2 + 1000W, which is a parabola opening downwards. The maximum value of this function can be found by completing the square or by using the vertex form of a parabola.

The vertex of the parabola, which gives the maximum area, occurs at W = -b/(2a), with 'a' being the coefficient of

W^2 (-2 in this case) and 'b' the coefficient of W (1000 in this case). Plugging these values in, we find that

W = -1000 / (2 * -2) = 250.

Therefore, the width that gives the maximum area is 250 feet. Substituting W back into the perimeter formula, we get

L = 1000 - 2*250 = 500 feet.

So, the dimensions for the maximum area are 500 feet by 250 feet, and the maximum area is A = 500 * 250 = 125,000 square feet.

Answer:

C. 14

Step-by-step explanation:

2 shirts in each pile x 7 piles of shirts = 14 shirts in total

2 x 7 = 14

Final answer:

To determine how many shirts Mark folded, multiply the number of shirts per pile (2) by the number of piles (7), which equals 14 shirts.

Explanation:

The question asks us to calculate the total number of shirts Mark folded if he put 2 shirts in each pile and there are 7 piles of shirts.

To find the total number of shirts, we need to multiply the number of shirts per pile by the number of piles. So, the calculation is as follows:

Determine the number of shirts per pile: 2 shirts.

Determine the total number of piles: 7 piles.

Multiply the number of shirts per pile by the number of piles: 2 shirts x7 piles = 14 shirts.

Therefore, Mark folded a total of 14 shirts.

Answer:

The value of k is 0.448.

Step-by-step explanation:

Given the exponential growth function is

[tex]A=23e^{kt}[/tex]

A= The population of the country

k= growth rate.

The population of the country increased by 10 million in 13 years after 1982.

Then the population is =(23+13)million = 36 million.

Here,

A= 36 million, t= 13

[tex]A=23e^{kt}[/tex]

[tex]\Rightarrow 36=23e^{13k}[/tex]

[tex]\Rightarrow e^{13k}=\frac{36}{23}[/tex]

Taking ln function both sides

[tex]\Rightarrow ln|e^{13k}|=ln|\frac{36}{23}|[/tex]

[tex]\Rightarrow {13k}=ln|\frac{36}{23}|[/tex]

[tex]\Rightarrow {k}=\frac{ln|\frac{36}{23}|}{13}[/tex]

[tex]\Rightarrow k=0.448[/tex]

The value of k is 0.448.

Answer:

Step-by-step explanation:

The ball hits the ground at t=0 or t=3 seconds. The maximum height of the ball is 9 feet. The ball reaches its highest point at t=1.5 seconds.

To find out how long after the kick the ball hits the ground, we need to solve the equation h=-4t^2+12t  for t when h=0. We can set the equation to zero and solve for t by factoring or using the quadratic formula. In this case, you can factor out a t from the equation and solve for t to find that t=0 or t=3.

To find out how high the soccer ball gets, we need to find the maximum height of the ball. The maximum height occurs at the vertex of the parabolic equation. The formula for finding the x-coordinate of the vertex is x = -b/2a. In this case, a = -4 and b = 12, so the x-coordinate of the vertex is x = -12/(2*-4) = 1.5. Substituting this value into the equation, we can find the maximum height by solving for h, which is h = -4*(1.5)^2 + 12*(1.5) = 9 feet.

The soccer ball hits its highest point at the x-coordinate of the vertex. In this case, the highest point occurs at t = 1.5 seconds.
