The requried, local minimum and maxium for the given function is √2 and -√2.

We need to find the local maximum and local minimum of the function [tex]f(x) = 2x + 4x^{(-1)}.[/tex]

First, we find the derivative of f(x):

[tex]f'(x) = 2 - 4x^{(-2)} = 2 - 4/x^2[/tex]

Setting f'(x) = 0 to find the critical points:

[tex]2 - 4/x^2 = 0[/tex]

Solving for x, we get:

x = ±√2

To determine whether these critical points are local maxima or minima, we need to examine the sign of the second derivative:

[tex]f''(x) = 8x^{(-3)}[/tex]

When x = √2, f''(√2) = 8/(√2)³ = 8√2 > 0, so x = √2 is a local minimum.

When x = -√2, f''(-√2) = 8/(-√2)³ = -8√2 < 0, so x = -√2 is a local maximum.

Answer:

d    ↔   - π

e    ↔    - √8

f     ↔    - 3/2

Step-by-step explanation:

Point d is to the left of -3

All points to the left of - 3 will be smaller than -3

Smaller than -3 means the absolute value will be greater than 3 but prefixed with a negative sign

Thus - 3.5 < - 3

-4 < -3

-99 < -3

etc

π = 3.14 approx

- π = - 3.14

- 3.14 < -3 and so it is to the left of -3. The only point to the left of -3 is point d

Similarly points to the right of -3 will have absolute values > 3 but prefixed by a negative sign

So -2.5, -2, -1, -0.5 etc are all greater than -3

√8 = √(4 · 2) = √4 · √2 = 2√2

√2 ≈ 1.414

so 2√2 ≈ 2.818

-√8 = - 2.818

so it is to the right of -3 but very close to -3

That would be point e

That leaves -3/2

-3/2 = - 1 1/2 and therefore lies halfway between -2 and - 1

That would be point f

A. The growth rate k is approximately 0.013, which means that the home value is increasing by about 1.3% per year

B.  The exponential model for the value of the home is V(t) = $95,000e^(0.013t).

C. The predicted value of the home in 2022 is approximately $123,539.

D. The value of the home reached $130,000 approximately 11.91 years after 2011, which is in 2023.

An exponential model is a mathematical model that describes exponential growth or decay. It is a function of the form [tex]y = ab^x[/tex], where a and b are constants, and x is the variable that represents time or another independent variable.

(a) To find the growth rate k, we can use the initial and final values of the home and the time period in between:

V(0) = $95,000 (the initial value in 2011)

V(7) = $105,000 (the final value in 2018, 7 years later)

Using the exponential model V(t) = V0ekt, we can set up the following equation:

V(7)[tex]= V(0)e^(k7)[/tex] = $105,000

$105,000/$95,000 = [tex]e^(k7)[/tex]

ln($105,000/$95,000) = k7ln(e)

k = ln($105,000/$95,000)/7 ≈ 0.013

The growth rate k is approximately 0.013, which means that the home value is increasing by about 1.3% per year.

(b) The exponential model for the value of the home is V(t) = $95,000e^(0.013t).

(c) To predict the value of the home in 2022, we can use t = 11 (since 2022 is 11 years after 2011) in the exponential model:

V(11) = $95,000e^(0.013*11) ≈ $123,539

The predicted value of the home in 2022 is approximately $123,539.

(d) To find the year when the value of the home reached $130,000, we can set up the following equation:

$130,000 = $95,000e^(0.013t)

ln($130,000/$95,000) = 0.013t

t ≈ 11.91

Hence, the area of the patio is approximately 226.98 square feet, rounded to the nearest tenth.

In geometry, the circumference is the perimeter of a  ellipse or circle . That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.

Area is the measure of a region size on a surface. The area of a plane area  or plane region  refers to the area of a planar lamina or shape , while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

To  determine the area of a  circular patio, we need to know its radius , by using  the formula:

Circumference = 2 *[tex]\pi[/tex]* radius

where [tex]\pi[/tex]  is  approximately 3.14.

radius = [tex]\frac{Circumference}{2 * \pi}[/tex]

according to  question,

radius = [tex]\frac{53.38}{2 * 3.14}[/tex] ≈ 8.5 feet

Now  , we know  that the area of a circle:

Area = [tex]\pi * radius^{2}[/tex]

Substituting the value of the radius

Area = 3.14 *[tex](8.5 feet)^{2}[/tex] ≈ 226.98 square feet

Therefore, the area of the patio is approximately 226.98 square feet, rounded to the nearest tenth.

The directed distance from point A to the curve at the angle theta = 5[tex]\pi[/tex]/6 is:

[tex]\sqrt(192 + 48\sqrt(3))[/tex]

To find the directed distance from point A to the curve at the angle theta = 5[tex]\pi[/tex]/6, we first need to find the equation of the tangent line to the curve at point A.

To do this, we can take the derivative of the curve equation with respect to x:

[tex]2x + 2y * dy/dx + 8 = 0[/tex]

Solving for dy/dx, we get:

[tex]dy/dx = -x / (y + 4)[/tex]

At point A, we have x = -4 and y = 4, so:

[tex]dy/dx = -(-4) / (4 + 4) = 1/2[/tex]

Therefore, the equation of the tangent line to the curve at point A is:

[tex]y - 4 = (1/2) * (x + 4)[/tex]

Simplifying, we get:

[tex]y = (1/2) * x + 6[/tex]

Now we can find the intersection point of the tangent line with the line passing through point A and making an angle of 5π/6 with the positive x-axis.

The line passing through point A with angle 5π/6 has slope:

[tex]tan(5\pi /6) = -\sqrt(3)[/tex]

So the equation of this line is:

[tex]y - 4 = -\sqrt(3) * (x + 4)[/tex]

Simplifying, we get:

[tex]y = -\sqrt(3) * x + 4\sqrt(3) + 4[/tex]

Now we can solve for the intersection point of the two lines. Setting the equations for y equal to each other, we get:

[tex](1/2) * x + 6 = -\sqrt(3) * x + 4\sqrt(3) + 4[/tex]

Solving for x, we get:

[tex]x = -8 / (2 + \sqrt(3))[/tex]

Now we can find the corresponding value of y using either equation for the tangent line or the line with angle 5π/6. Using the equation for the tangent line, we get:

[tex]y = (1/2) * (-8 / (2 + \sqrt(3))) + 6 = 11 - 4\sqrt(3) / (2 + \sqrt(3))[/tex]

The directed distance from point A to this intersection point is the distance between these two points along the line with angle 5π/6. This distance can be found using the distance formula:

[tex]d = \sqrt((x2 - x1)^2 + (y2 - y1)^2)[/tex]

Plugging in the values, we get:

[tex]d = \sqrt((-4 - (-8 / (2 + \sqrt(3))))^2 + (4 - (11 - 4\sqrt(3) / (2 + \sqrt(3))))^2)[/tex]

Simplifying, we get:

[tex]d = \sqrt(192 + 48\sqrt(3))[/tex]

Therefore, the directed distance from point A to the curve at the angle theta = 5π/6 is:

[tex]\sqrt(192 + 48\sqrt(3))[/tex]

The directed distance from point A to the point on the curve corresponding to θ = 5π/6 is 4 units.

What is curve?

In mathematics, a curve refers to a continuous and smooth line that has no corners or edges. Curves can be described using equations or parametric equations, and they can be represented in a two-dimensional or three-dimensional space.

To find the directed distance when θ = 5π/6, we first need to find the corresponding point on the curve.

The equation [tex]x^2 + y^2 + 8x = 0[/tex] can be rewritten as [tex](x + 4)^2 + y^2 = 16[/tex], completing the square. This is the equation of a circle with center (-4, 0) and radius 4.

To find the point on the circle corresponding to θ = 5π/6, we can use polar coordinates. Let r be the radius of the circle (r = 4), and let θ be the angle from the positive x-axis to the point we want to find. Then we have:

x = r cos(θ) = 4 cos(5π/6) = -2√3

y = r sin(θ) = 4 sin(5π/6) = 2

So the point on the curve corresponding to θ = 5π/6 is (-2√3, 2).

To find the directed distance from point A (-4, 4) to this point, we can use the distance formula:

distance = √[[tex](x2 - x1)^2 + (y2 - y1)^2[/tex]]

= √[[tex](-2\sqrt3 - (-4))^2 + (2 - 4)^2[/tex]]

= √[12 + 4]

= 2√4

= 4

Standard Deviation = 7.4

Standard deviation (denoted by symbol: σ ) is a measure of how dispersed or spread out the data is in relation to the mean. i.e, by how much the data deviates from the mean. A low standard deviation represents a sample that has its data clustered around the mean, and a high standard deviation represents indicates the data is more dispersed.

There are two primary ways of calculating the standard deviation. One is with the calculator, which will depend on what model/brand you use. The other method involves the formula for standard deviation:

144 = 28x + 2y

The second equation relates the number of shirts to the number of hours and the average rate:

y = 4x

This is the system of equations we need to solve:

The domain is 0 ≤ b ≤ 6 and the range is c ≥ 30.In this situation, the function that models the total weight of a shipping crate is given as c = 24b + 30, where c represents the total weight of the crate and b represents the number of boxes packed inside.

To determine the domain and range of this function, we need to consider the constraints of the problem. It is mentioned that each crate holds a maximum of 6 boxes.

Domain: The domain refers to the set of input values that the function can accept. In this case, the number of boxes (b) cannot exceed 6 since that is the maximum capacity of each crate. Therefore, the domain of the function is 0 ≤ b ≤ 6, where b is a non-negative integer.

Range: The range represents the set of possible output values of the function. The total weight of the crate (c) is determined by the number of boxes packed inside. Since the weight of the crate increases linearly with the number of boxes, there is no upper limit to the range. The range of the function is c ≥ 30, where c is a non-negative integer representing the weight of the crate.

Answer:

24 inches

Step-by-step explanation:

First, we need to convert the height of the wall to inches since the diameter of the window is given in inches:

18 feet = 18 x 12 inches = 216 inches

Next, we can find the distance from the floor to the top of the window by subtracting the height of the door from the height of the wall and then dividing by 2 (since the window will be centered above the door):

Distance from floor to top of window = (216 inches - 80 inches) / 2 = 68 inches

Finally, we can use the Pythagorean theorem to find the distance from the ceiling to the top of the window. We can consider the triangle formed by the height of the wall, the distance from the floor to the top of the door, and the distance from the floor to the top of the window. We can let x be the distance from the floor to the top of the window, then we have:

x^2 + 80^2 = 216^2

Simplifying this equation, we get:

x² = 216² - 80²

x² = 43,296 - 6,400

x² = 36,896

x = [tex]\sqrt{36,896}[/tex] = 192 inches

Therefore, the distance from the ceiling to the top of the window is:

Distance from ceiling to top of window = 216 inches - 192 inches = 24 inches

So the distance from the ceiling to the top of the window is 24 inches.

Answer:

If y varies directly with the square of x, we can express this relationship using the equation:

y = kx^2

where k is the constant of proportionality. To find the value of k, we can use the given information that y is 16 when x is 8:

16 = k * 8^2

Simplifying the equation, we get:

16 = 64k

Dividing both sides by 64, we get:

k = 16/64 = 1/4

So the equation that relates y and x is:

y = (1/4)x^2

We can use this equation to find the value of y for any given value of x. For example, if x is 10, we have:

y = (1/4) * 10^2 = 25

Therefore, when x is 10, y is 25.

The missing side of the triangle given the angle as 71° and hypotenuse as 17 to the nearest tenth is 16.1.

The correct answer choice is option C

Hypotenuse= 17

Opposite = x

Angle = 71°

Sin 71° = opposite / hypotenuse

sin 71° = x / 17

0.95105 = x / 17

cross product

0.95105 × 17 = x

x = 16.1 to the nearest tenth

In conclusion, the missing side of the triangle to the nearest tenth is 16.1

The sums are 48, 52, 39, and 50

According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.

Given here: The addition of three numbers

When adding, always line up the addends, the two numbers being combined, one on top of each other according to their place values. Add the numbers in the ones column first, then the tens column, and finally the hundreds column, to get the sum, or the total.

1) [tex]24+14+10=\bold{48}[/tex]

2) [tex]17+25+10=\bold{52}[/tex]

3) [tex]16+13+10=\bold{39}[/tex]

4) [tex]26+14+10=\bold{50}[/tex]

Thus the sums of the respective equations gives 48, 52, 39, and 50 respectively

The measure of the angle is 35 degrees.

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.

Let's assume that x is the measure of the angle in question.

The complement of x is the angle that, when added to x, forms a right angle (90 degrees). Therefore, the complement of x can be represented as 90 - x.

According to the problem, the measure of the angle is 130 less than three times its own complement. We can write this information as an equation:

x = 3(90 - x) - 130

Simplifying and solving for x, we get:

x = 270 - 3x - 130

4x = 140

x = 35

Therefore, the measure of the angle is 35 degrees.

Answer: 27

Step-by-step explanation:

V=lwh  

V=(3)(3)(3)

Answer:

27 units

Step-by-step explanation:

If we say the cube is broken up into smaller cubes, volume is the number of tiny cubes total.

An easier way to do this is to remember that the volume equation is V=L*w*h= length*width*height, where the width is 3 cube units, the height is 3 cube units, and the length is 3 cube units. So:

V=3*3*3= 27

If this does not make sense, here is another way to think about volume.

First, lets determine what the area of one surface of the cube is. Area is length times width, so the answer is 9. We can also count the number of cubes, if that is easier.

So we found the area of one face. Now we need to know how many of these square areas makes up the cube. That is, how many 3 by squares will make the cube? From the diagram, we see that there are three cube units across, and if each face area has a width of one cube, then we multiply.

3*9= 27
