In 2011, there were approximately 2.8 million nurses in a large country, with demand for nurses expected to increase by 0.044 million each year. a. Assuming the number of nurses in 2011 represents the demand for that year, express the demand for nurses in the country, D, in millions, as a function of the number of years after 2011,x. b. If the demand increases as expected, during which year will demand for nurses in the country reach 3.5 million? a. D(x)=

Answers

The demand for nurses in the country can be expressed as the function D(x) = 2.8 + 0.044x. The year in which the demand for nurses in the country will reach 3.5 million is in 2027.

a. The demand for nurses in the country can be expressed as a function of the number of years after 2011, x, by using the equation D(x) = 2.8 + 0.044x. This equation represents the initial demand in 2011 (2.8 million) plus the expected increase in demand each year (0.044 million) multiplied by the number of years after 2011 (x).

b. To find the year in which the demand for nurses will reach 3.5 million, we can set D(x) equal to 3.5 and solve for x:

3.5 = 2.8 + 0.044x

0.7 = 0.044x

x = 0.7 / 0.044

x = 15.9

Since x represents the number of years after 2011, we can add 15.9 to 2011 to find the year in which the demand will reach 3.5 million:

2011 + 15.9 = 2026.9

Therefore, the demand for nurses in the country will reach 3.5 million during the year 2027.

One Monday in December, it was `-8`ºC in Harbin, China and `-2`ºC in Beijing, China. Which city was colder on that day?

Answers

Harbin was colder than Beijing on that particular day in December because the temperature difference between the two cities was -6ºC.

To figure out which city was colder, we need to compare the difference between the temperatures of the two cities. The temperature difference is the numerical value we get when we subtract one temperature from the other.

In this case, the temperature in Harbin was -8ºC and the temperature in Beijing was -2ºC. To find out which city was colder, we need to calculate the temperature difference between the two cities.

To do this, we subtract the temperature in Beijing from the temperature in Harbin:

-8ºC - -2ºC = -6ºC

So the temperature difference between the two cities is -6ºC. This means that Harbin was colder than Beijing on that day.

We can see that the temperature difference is negative, which tells us that the temperature in Harbin was lower than the temperature in Beijing.

You go to the park on a windy day to fly a kite. You have released 40 feet of string. The string makes an angle of 30°with the ground. How high is the kite in the air?

Answers

Answer:

20 feet

Step-by-step explanation:

You can use trigonometry to solve this problem. The height of the kite can be found using the sine function. The sine of an angle in a right triangle is equal to the length of the side opposite the angle divided by the length of the hypotenuse.

In this case, the side opposite the 30° angle is the height of the kite (h), and the hypotenuse is the length of the string (40 feet). So we have:

sin(30°) = h / 40

Solving for h, we get:

h = 40 * sin(30°)

Since sin(30°) = 0.5, we have:

h = 40 * 0.5

So, h = 20 feet.

The kite is 20 feet high in the air.

Answer:

To solve this problem, we can use trigonometry. Let's assume that the height of the kite from the ground is h. Then, we can use the tangent function to find the value of h.

We know that the tangent of an angle is equal to the opposite side over the adjacent side. In this case, the opposite side is the height of the kite (h) and the adjacent side is the distance from you to the point directly below the kite on the ground, which is 40 feet.

So we have:

tan(30°) = h/40

Multiplying both sides by 40, we get:

h = 40 tan(30°)

Using a calculator, we can find the value of tangent of 30 degrees, which is approximately 0.5774. So:

h = 40 × 0.5774 ≈ 23.1

Therefore, the height of the kite in the air is approximately 23.1 feet.

Evaluate det (A) by a cofactor expansion along a row or column of your choice. A=[[-6,0,2],[2,4,1],[-1,0,3]]

Answers

The determinant of matrix A is -6.

A. To evaluate det(A) by a cofactor expansion along a row or column of your choice, we can choose any row or column and multiply each element by its corresponding minor and sign.

For example, let's choose the first row:

det(A) = (-6)(4*3-0*1) + (0)(2*3-(-1)*2) + (2)(2*0-(-1)*4)

det(A) = (-6)(12) + (0)(6) + (2)(4)

det(A) = (-72) + (0) + (8)

det(A) = -64

Therefore, the determinant of matrix A is -64.



B. Alternatively, we could have chosen any other row or column and the result would have been the same. For example, if we chose the third column:

det(A) = (2)(4*0-2*0) + (-1)(-6*3-2*0) + (3)(-6*0-2*4)

det(A) = (2)(0) + (-1)(-18) + (3)(-8)

det(A) = (0) + (18) + (-24)

det(A) = -6

Therefore, the determinant of matrix A is -6.

Note that the determinant of a matrix is a scalar value, and it is the same regardless of which row or column we choose to expand along.

a company is building square-bottomed boxes with no tops. the material for the bottom costs $2 per cm2 and the material for the sides costs $1 per cm2. the company has budgeted $96 to build one box. what is the box of largest volume the company can build for $96

Answers

The box of largest volume the company can build for $96 is the box that costs exactly $96.

The company can build a box of the largest volume for $96 by calculating the area of the bottom and sides of the box. To calculate the area of the bottom, use the formula A=l x w, where l is the length of one side and w is the width of one side. Since the bottom is square, l=w. Thus, A=l^2. The area of the bottom is then multiplied by the cost of the material for the bottom, which is $2 per cm2, to calculate the total cost of the bottom.

Similarly, to calculate the cost of the sides, use the formula A=2lh + 2wh, where h is the height of the box. The area of the sides is then multiplied by the cost of the material for the sides, which is $1 per cm2, to calculate the total cost of the sides.

The total cost of the box is the cost of the bottom plus the cost of the sides. Since the company has budgeted $96 to build one box, the total cost of the box must not exceed $96. Therefore, the box of largest volume the company can build for $96 is the box that costs exactly $96.

population 31,200 now... increase 10% per year... what ws the population 2 years ago?

Answers

The population two years ago was 28,080.

To calculate this, we need to use the following formula: Population two years ago = Population now - (Population increase rate x Number of years). Therefore, the population two years ago was 31,200 - (10% x 2) = 28,080.

We can also look at this another way. To calculate the 10% increase per year, we can use the following formula: Population increase rate = (Population now - Population two years ago) / Number of years. Therefore, 10% = (31,200 - 28,080) / 2 = 3,120.

We can use this same formula to calculate the population three years ago. Using the same formula, the population three years ago was 25,960.

To summarize, the population two years ago was 28,080 and the population three years ago was 25,960. The population has been increasing by 10% each year.

Answer:

Area = 15.6

Perimeter = 20.6

Step-by-step explanation:

Both smaller triangles are right triangles

The left triangle is isosceles right triangle since 2 angles are 45o so AB is hypotenuse and the other 2 sides are equal

so c^2 = a^2 + b^2

c^2 = 2a^2

(3√2)^2 = 2a^2

2a^2 = 18

a^2 = 9

a = 3

For the right triangle the angle at B is 60o, hypotenuse is BC

so cos(60) = adjacent/hypotenuse

1/2 = 3/BC

=> BC = 6

sin(60) = opposite/hypotenuse

√3/2 = opp/6

opp = 3√3

so AC = 3 + 3√3 = 6√3

Area of triangle = A = 1/2bh = 1/2(6√3)(3) = 9√3 = 15.6

Perimeter = 3√2 + 6√3 + 6 = 20.6

Teresa can paddle her kayak 6 miles per hour in still water. It takes her as long to paddle 9 miles upstream as it takes her to travel 27 miles downstream. Determine the speed of the river's current.

Answers

The speed of the river's current is 3 miles per hour.

How To determine the speed

To determine the speed of the river's current, we can use the formula d = rt, where d is the distance, r is the rate, and t is the time.

We can set up two equations, one for upstream and one for downstream, and solve for the speed of the river's current.

For upstream:

9 = (6 - c)t

For downstream: 27 = (6 + c)t

Since it takes her the same amount of time to paddle 9 miles upstream as it does to travel 27 miles downstream, we can set the two equations equal to each other:

9 = (6 - c)t = 27 = (6 + c)t

Simplifying and solving for c:

9(6 + c) = 27(6 - c) 54 + 9c = 162 - 27c 36c = 108 c = 3

Therefore, the speed of the river's current is 3 miles per hour.

The points F(8,-1), G(2,1), H(1, -2), and I(7,-4) form a quadrilateral. Find the desired slopes and lengths, then fill in the words that BEST identifies the type of quadrilateral.

Answers

The points F(8,-1), G(2,1), H(1, -2), and I(7,-4) form a quadrilateral. The desired slopes and lengths are follows:

Slopes:
FG: m = -1/3
GH: m = 3
HI: m = -1/3
IF: m = 3 Lengths:
FG: d = √ 2√(10)
GH: d =  = √(10)
HI: d =2√(10)
IF: d = √(10)

The type of quadrilateral that BEST identifies the given points is a parallelogram.

To find the slopes and lengths of the quadrilateral, we will use the slope formula and the distance formula.

Slope formula: m = (y2 - y1)/(x2 - x1)
Distance formula: d = √((x2 - x1)² + (y2 - y1)²)

Slopes:
FG: m = (1 - (-1))/(2 - 8) = -1/3
GH: m = (-2 - 1)/(1 - 2) = 3
HI: m = (-4 - (-2))/(7 - 1) = -1/3
IF: m = (-1 - (-4))/(8 - 7) = 3

Lengths:
FG: d = √((2 - 8)² + (1 - (-1))²) = √(40) = 2√(10)
GH: d = √((1 - 2)²+ (-2 - 1)²) = √(10)
HI: d = √((7 - 1)^2 + (-4 - (-2))²) = √(40) = 2√(10)
IF: d = √((8 - 7)² + (-1 - (-4))^2) = √(10)

From the above calculations, we can see that the slopes of FG and HI are equal, and the slopes of GH and IF are equal. This means that the opposite sides of the quadrilateral are parallel. Additionally, the lengths of FG and HI are equal, and the lengths of GH and IF are equal. This means that the opposite sides of the quadrilateral are also congruent.

Therefore, the type of quadrilateral that BEST identifies the given points is a parallelogram.

Answers

The number of fruits that Kim bought in all, given the apples and oranges was ;

8 oranges 11 apples

How to find the number of fruits ?

Let's call the number of oranges that Kim bought "O" and the number of apples that Kim bought "A".

From the problem, we know that Kim bought fewer than 20 pieces of fruit, so we can write:

A + O < 20

A = O + 3

Simplifying:

2O + 3 < 20

2O < 17

O < 8.5

Since O represents the number of oranges, we know that Kim bought fewer than 8.5 oranges. Since she can't buy a fraction of an orange, this means that she must have bought either 8 oranges or fewer.

Now we can use the equation A = O + 3 to find the number of apples she bought:

A = 8 + 3 = 11

Answers

The total number of popsicle sticks needed to make one snowman using the given conditions for system of equations is equal to 9.

Let us consider 'x' is the number of popsicle sticks required to make one pencil cup.

And 'y' represents the number of popsicle sticks required to make one snowman.

The required set up two equations are,

8x + 15y = 271  ___(1)

14x + 15y = 373 ___(2)

Multiplying both sides of equation (1) by 14 and both sides of equation (2) by -8 we get,

112x + 210y = 3794

-112x - 120y = -2984

Add both the above equations to eliminate the x variable we get,

⇒ 112x + (-112x) + 210y + (-120y) = 3794 + (-2984)

Simplifying the equation we get,

⇒90y = 810

Dividing both sides by 90 we get,

⇒ y = 9

Therefore, number of popsicle sticks required to make one snowman is equal to 9.

α = (1 2)(2 3)(3 4)(4 5)(5 1)(6 7)(7 8)(8 6)
β = (1 1)(2 3)(3 8)(8 4)(4 7)(7 1)(5 6)(6 5)
γ = (1 2)(2 3)(3 5)(5 1)(4 5)(5 6)(6 8)(8 4)
Since α and β have an even number of 2-cycles, they are even permutations. γ has an odd number of 2-cycles, so it is an odd permutation.

(d) The inverse of each permutation can be found by reversing the order of the elements in each cycle. The inverses can be written as a product of disjoint cycles as follows:
[tex]α^-1 = (1 2 3 4 5)(6 8 7)β^-1 = (1)(2 7 4 8 3)(5 6)γ^-1 = (1 5 3 2)(4 8 6 5)[/tex]

(e) The products αβ and βα can be found by performing the permutations in the given order. The products can be written as a product of disjoint cycles as follows:
αβ = (1 6 8 4 7 2 3 5)(5 1)
βα = (1 7 4 8 6 5 3 2)(2 1)
The order of αβ is lcm(8, 2) = 8, and the order of βα is lcm(8, 2) = 8.

A student used factor by grouping to factor the expression below. How can you tell that the student made an error when​ factoring? Explain the error.

​Student's work: ​ 6x² ​ – x​ – 12
6x² ​ – 9x​ + 8x ​ – 12
3x(2x ​ – 3)​ – 4(–2x​ +3)

Answers

The error made by the student is instead of taking +4 as common he has taken - 4 as common.

Factoring by grouping terms:

To factor an expression by grouping, we need to look for groups of terms that have common factors. Then, we factor out those common factors from each group and see if there is a common factor that can be further factored out.

Here we have

6x² ​ – x​ – 12  

The above expression can be factorized as follows

=> 6x² – x – 12

= 6x² – 9x + 8x – 12        [ Splitting the middle term ]

= 3x(2x – 3) + 4(2x – 3)     [ Grouping the terms ]  

= (3x + 4)(2x – 3)  

Hence, the factors of given expression are (3x + 4) and (2x – 3)  

The error made by the student is in step 3 instead of taking +4 as common he has taken - 4 as common which doesn't give the common factors in the next step taken.    

Therefore,

The error made by the student is instead of taking +4 as common he has taken - 4 as common.

Julian makes and sells wallets. He estimates that his income can be modeled by y = 18x - 140, where x is the number of wallets he sells. He estimates that his costs to make the wallets can be modeled by y = 7x+160. How many wallets does Julian need to make in order to break even?

Answers

Therefore , the solution of the given problem of equation comes out to be julian must  sell at least 28 wallets in order to make even.

How do equations operate?

Mathematical formulas frequently use the same variable letter to try to impose unity between two assertions. Many academic numbers are shown to be equal using mathematical fraction equations, also known as assertions. Using y + 6 as an illustration, the normalise does not divide 12 into two parts, but instead b + 6. It is possible to determine the connection between each sign part and the number of lines. The significance of a symbol usually contradicts itself.

Here,

For Julian to break even, his revenue must match his expenses. Therefore, we can equalise the two equations and find x:

=> 18x - 140 = 7x + 160

7x is subtracted from both lines to yield:

=> 11x - 140 = 160

140 added to both ends results in:

=> 11x = 300

When we multiply both parts by 11, we get:

=> x = 27.27 (rounded to two integer places) (rounded to two decimal places)

We can round up to the nearest whole amount because Julian cannot sell a fraction of a wallet. Julian must therefore sell at least 28 wallets in order to make even.

when an integer m is divided by 5 the remainder is 3. When m is divided by 7 the remainder is 1. If m is greater than 40 but less than 80, what is one possible value of m.

Answers

One possible value of m is 53.

A possible value of m can be found using the Chinese Remainder Theorem. The Chinese Remainder Theorem states that if two numbers a and b are relatively prime, then there exists an integer x such that:
x ≡ a (mod m)
x ≡ b (mod n)


In this case, we have:
m ≡ 3 (mod 5)
m ≡ 1 (mod 7)

Both 5 and 7 are prime so we can start by finding the smallest positive integer that is congruent to 3 (mod 5) and 1 (mod 7). This integer is 18:

18 ≡ 3 (mod 5)
18 ≡ 1 (mod 7)

Now, we can add multiples of 5*7 = 35 to 18 until we find a value of m that is greater than 40 but less than 80:

18 + 35 = 53

53 is greater than 40 but less than 80, so one possible value of m is 53.

Therefore, one possible value of m is 53.
