Answer:

81

Step-by-step explanation:

Any number, wether it is negative or postive, will always be postive when there is a even exponent.

In this case, we have a -9, and a exponent thats 2.

Since 2 is a even number, -9^2 will be a postive value.

Now, what is the actual value of this?

Well, a exponent of 2 basiclly means 2 numbers being multiplied together.

Or in this case, 2 negative 9s being multiplied together.

THis will be:

-9*-9

=

As I said above, a even exponent makes a negative number postive.

You see here that a negative 9 is being multiplied by -9. When two negative numbers multiply together, they make a postive.

THis is why a even exponent makes a postive.

Hope this helps!

The total number of ways in which elements from set-1 can be arranged in a line is given by the permutation of 10 elements, denoted by P(10), which is 10!. So, the total number of ways to arrange 10 elements in a line is 10! = 3,628,800.

If set-1 consists of 10 elements, the total number of ways in which elements from s1 can be arranged in a line is given by the permutation of 10 elements, denoted by P(10), which is:

P(10) = 10!

This means that there are 10 ways to choose the first element, 9 ways to choose the second element (since one element has already been chosen), 8 ways to choose the third element (since two elements have already been chosen), and so on, until there is only 1 way to choose the last element.

Therefore, the total number of ways to arrange 10 elements in a line is 10! = 3,628,800.

The function \(f(x) = 2x^2 - 3x + 2\) has a relative minimum at (3/4, 5/8) and an absolute minimum at (3/4, 5/8), and an absolute maximum at (3, 11).

To find the relative and absolute extrema of the function \(f(x) = 2x^2 - 3x + 2\) with domain [0, 3], we need to follow these steps:

Find the critical points of f(x) by solving f'(x) = 0.

Test the critical points and the endpoints of the domain to determine the relative and absolute extrema.

Step 1: Find the critical points of f(x) by solving f'(x) = 0.

\(f(x) = 2x^2 - 3x + 2\)

f'(x) = 4x - 3

Setting f'(x) = 0, we get:

4x - 3 = 0

4x = 3

x = 3/4

So, the critical point of f(x) is x = 3/4.

Step 2: Test the critical points and the endpoints of the domain to determine the relative and absolute extrema.

\(f(0) = 2(0)^2 - 3(0) + 2 = 2\)

\(f(3) = 2(3)^2 - 3(3) + 2 = 11\)

\(f(3/4) = 2(3/4)^2 - 3(3/4) + 2 = 5/8\)

To determine the relative and absolute extrema, we need to examine the sign of f'(x) around each critical point and at the endpoints of the domain.

When x < 3/4, f'(x) < 0, which means that f(x) is decreasing. When x > 3/4, f'(x) > 0, which means that f(x) is increasing. Therefore, the function has a relative minimum at x = 3/4.

Since f(3/4) is the lowest point on the function, it is also an absolute minimum.

The function has an absolute maximum at x = 3, and no other relative extrema.

Therefore, the function \(f(x) = 2x^2 - 3x + 2\) has a relative minimum at (3/4, 5/8) and an absolute minimum at (3/4, 5/8), and an absolute maximum at (3, 11).

Answer:

Step-by-step explanation:

You are correct in what you are doing. All you need do is show that what you got can be expressed algebraically.

Let x be the time in hours.

Let y be the snowfall in inches.

The first one does not work.

y = k * x

12 = k * 6                     Divide both sides by 6

12/6 = k/6

k = 2

All the rest will fit into this equation.

try x = 2.5

y = k * x

y = 2 * 2.5

y = 5           which is just the amount of snowfall you should get.

Answer:

The answer is 129.

Step-by-step explanation:

The two inequalities that define the shaded region in the diagram are:

y ≥ 4 and y < x

For the solid vertical line, the slope (m) is 0. The inequality sign we would use would be "≥"  because the shaded region is to the left and the boundary line is solid.

The y-intercept is at 4, therefore, substitute m = 0 and b = 4 into y ≥ mx + b:

y ≥ 0(x) + 4

y ≥ 4

For the dashed line:

m = change in y / change in x = 1/1 = 1

b = 0

the inequality sign to use is: "<"

Substitute m = 1 and b = 0 into y < mx + b:

y < 1(x) + 0

y < x

Thus, the two inequalities are:

y ≥ 4 and y < x

Step-by-step explanation:

Using Algebraic expression solution ,

The cost of three hats is $18 .

We have given that,

A hat company charge for design fee $4 per hat .

i.e design fee of one hat = $4

total cost of 5 hats = $30

let the cost of one hat without design fee be $x and total cost of one hat is $(x+4) .

using the above statement, we get an algebraic expression,

5( x+ 4)= 30

we solve the above algebra expression,

=> 5x + 20 = 30

=> 5x = 10

=> x = 2

so, cost of a hat without design fee is $2

and total cost of one hat is $6.

we have to calculate cost of 3 hats .

cost of one hat in hat company= $ 6

cost of three hats in hat company= $(6×3)

= $18

Hence, the total cost of 3 hats is $18.

Step-by-step explanation:

The slope of the straight line that passes through the points (5,11) and (14,-10) is \(\frac{-7}{3}\).

''A straight line is an endless one-dimensional figure that has no width. A straight line is a combination of endless points joined on both sides of a point.''

Given, two points are (5, 11) and (14, -10).

Let, the line that passes through both these points has a slope = m.

Where, m = \(\frac{y_2 - y_{1} }{x_2- x_{1} }\).

Here, (y₂ - y₁) = Change in the value of y.

(x2 - x₁) = Change in the value of y.

Therefore, \(\frac{y_2 - y_{1} }{x_2- x_{1} }\) = \(\frac{-10 - 11}{14 - 5}\) = \(\frac{-21}{9}\) = \(\frac{-7}{3}\)

The explicit solution to the given initial value problem

y′=(1−y)5/4 with y(0)=0 is

y(x) = \(1 - (1 - e^x)^4/5\)

The given first-order differential equation is separable, which means that we can separate the variables and write the equation in the form

\(dy/(1-y)^(5/4) = dx.\)

Integrating both sides, we get \((1-y)^(-1/4)\) = 5/4 * x + C, where C is the constant of integration. Solving for y, we get y(x) = 1 -\((1 - e^x)^4/5\).

Using the initial condition y(0) = 0, we can solve for C and get C = 1. Therefore, the explicit solution to the initial value problem is

\(y(x) = 1 - (1 - e^x)^4/5.\)

Answer:

To the nearest tenth, the length is 6.4 meters, and the width is 3.4 meters.

Step-by-step explanation:

Let w be the width of the rectangle. Then l = w + 3, and we have:

\( w(w + 3) = 22\)

\( {w}^{2} + 3w = 22\)

\( {w}^{2} + 3w - 22 = 0\)

Calculating the discriminant:

\( \sqrt{ {3}^{2} - 4(1)( - 22)} = \sqrt{9 + 88} = \sqrt{97} \)

So by the quadratic formula, and discarding the negative solution, we then obtain:

\(w = \frac{ - 3 + \sqrt{97} }{2} = 3.4\)

\(l = w + 3 = 3.4 + 3 = 6.4\)

The Cobb-Douglas utility function satisfies the properties of local non-satiation, decreasing marginal utility for both goods, quasi-concavity, and homotheticity.

The Cobb-Douglas utility function u(x1, x2) = xi^(α) * x2^(β), where α and β are both greater than zero, satisfies the following properties:

(a) Local non-satiation:

This property states that at each point of the consumption set, there is always another bundle that is arbitrarily close and strictly preferred. Thus, the function has local non-satiation.

(b) Decreasing marginal utility for both goods 1 and 2: The marginal utility of a good measures the utility obtained by consuming one more unit of it. The marginal utility of x1 can be obtained as:

MU1 = α * xi^(α−1) * x2^(β)

The marginal utility of x2 can be obtained as:

MU2 = β * xi^(α) * x2^(β−1)

Therefore, both marginal utilities are decreasing in x1 and x2, satisfying this property.

(c) Quasi-concavity:

The Cobb-Douglas function is quasi-concave. This means that the upper contour set of any level set of the function is convex. This can be proved by taking the second partial derivative of the function and checking whether it is negative or not.

(d) Homotheticity:

The Cobb-Douglas function is homothetic. This means that its shape is independent of the total level of utility. The proof can be achieved by checking whether the function is homogeneous of degree one or not. This is true, since multiplying the inputs by any positive scalar λ leads to a proportional increase in the output.

In conclusion, the Cobb-Douglas utility function satisfies all four properties - local non-satiation, decreasing marginal utility for both goods 1 and 2, quasi-concavity, and homotheticity.

Answer:

28.56

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56

The angle the tower makes with the hill is approximately 44.77 degrees.

To find the angle the tower makes with the hill, we can use trigonometry. Let's denote the angle the tower makes with the hill as θ.

Using the given information, we can form a right triangle with the tower, the guy-wire, and the horizontal distance between the anchor point and the base of the tower.

The vertical leg of the triangle represents the height of the tower, which is 127 feet.

The hypotenuse of the triangle represents the length of the guy-wire, which is 175 feet.

The horizontal leg of the triangle represents the distance from the anchor point to the base of the tower, which is 64 feet.

We can use the sine function to find the angle θ:

sin(θ) = opposite/hypotenuse

sin(θ) = 127/175

To find θ, we can take the inverse sine (sin^(-1)) of both sides:

\(θ = sin^(-1)(127/175)\)

Using a calculator, we find that θ is approximately 44.77 degrees

Therefore, the angle the tower makes with the hill is approximately 44.77 degrees.
