What is the relative minimum of the function?

Answer:

4. [tex]7\sqrt{x}=14[/tex]

Step-by-step explanation:

Radical equation is a equation that has a variable under the radical .

From the given options we have radical square root

We need to choose an option that has a variable under the square root.

1.[tex]x+\sqrt{5}=12[/tex]

This equation has 5 under the radical square root. Variable is outside, So this is not a radical equation.

2. x^2=16

Here there is not radical . So this is not a radical equation.

3. [tex]3+x\sqrt{7}=13[/tex]

This equation has 7 under the radical square root. Variable is outside, So this is not a radical equation.

4. [tex]7\sqrt{x}=14[/tex]

This equation has x under the radical square root. So this is a radical equation.

In the proportion a/b = c/d, if this is true then the product of the extremes (a*d) is equal to the product of the means (b*c). Any statement that contradicts this property is considered false.

Looking at the given condition, a/b = c/d, it represents a proportion or a statement of equality between two fractions. Within this proportion, `a` and `d` are referred to as the extremes, while `b` and `c` are known as the means.

If the proportion is true, meaning it accurately reflects a relationship of equality between two ratios, several properties become applicable. Importantly, the product of the means equals the product of the extremes. In other words, in a valid proportion, `a*d` is equal to `b*c`.

Consequently, if any statement contradicts these properties, it is false. So, without knowing the specific statements to analyze here, we cannot accurately decide on the false one. Always remember, you need to comply with the stated properties of a proportion in mathematical contexts.

The farmer originally planted 15 apple trees.

Let's denote the original number of rows as [tex]\( r \)[/tex] and the original number of columns as [tex]\( c \).[/tex]

In the original arrangement, the total number of trees is [tex]\( r \times c \).[/tex]

If 5 more rows and 3 fewer columns are added, the new number of rows becomes [tex]\( r + 5 \)[/tex] and the new number of columns becomes [tex]\( c - 3 \).[/tex]

According to the given information, the new arrangement has 25 more trees than the original arrangement. So, we can set up the equation:

[tex]\[ (r + 5) \times (c - 3) = r \times c + 25 \][/tex]

Expanding the left side:

[tex]\[ r \times c + 5r - 3c - 15 = r \times c + 25 \][/tex]

Now, let's simplify:

[tex]\[ 5r - 3c - 15 = 25 \][/tex]

[tex]\[ 5r - 3c = 40 \][/tex]

Now, let's solve this equation to find the relationship between [tex]\( r \)[/tex] and [tex]\( c \).[/tex]

Given the information, let's make some assumptions about the number of rows and columns to fit the situation realistically.

Let's start with 1 row and 3 columns ( [tex]\( r = 1, c = 3 \)[/tex] ):

[tex]\[ 5(1) - 3(3) = 5 - 9 = -4 \][/tex]

It doesn't satisfy the condition.

Next, let's try 2 rows and 4 columns ( [tex]\( r = 2, c = 4 \)[/tex] ):

[tex]\[ 5(2) - 3(4) = 10 - 12 = -2 \][/tex]

Still doesn't satisfy the condition.

Next, let's try 3 rows and 5 columns ( [tex]\( r = 3, c = 5 \)[/tex] ):

[tex]\[ 5(3) - 3(5) = 15 - 15 = 0 \][/tex]

This satisfies the condition.

So, the original arrangement had 3 rows and 5 columns, and the total number of trees is [tex]\( 3 \times 5 = 15 \)[/tex].

Final answer:

To provide 275 balloons when they are sold in packs of 2, the clown will need to purchase 138 packs, which will include one extra balloon as you cannot buy half a pack.

Explanation:

The clown needs 275 balloons for a party and they come in packs of 2. To find out how many packs of balloons the clown needs to buy, one must divide the total number of balloons by the number in each pack.

The calculation is as follows:

Since packs cannot be purchased in halves, the clown will need to buy 138 packs to have enough balloons, understanding that this means having one extra balloon.

Final answer:

The width of the garden is 15 meters and the length is 36 meters.

Explanation:

To solve this problem, we can use the formulas for perimeter and length. Let's assume that the width of the rectangular garden is x.

According to the given information, the length is 6 meters longer than twice the width, so the length can be represented as 2x + 6.

The perimeter is the sum of all four sides of the rectangle, which is given as 102 meters. We can set up the equation:

2(2x + 6) + 2x = 102

Simplifying the equation, we get:

6x + 12 = 102

6x = 90

x = 15

Therefore, the width of the garden is 15 meters and the length is 2(15) + 6 = 36 meters.

The mean of the combined group is 71.78.

Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations.

Let the total sum of the scores of the first class of 36 students be ∑x.

Here, the mean is 75.2 .

⇒  ∑x/36 = 75.2

⇒ ∑x = (75.2)(36)

⇒ ∑x = 2707.2

Also, let the total sum of the scores of the second class of 28 students be ∑y.

Here, the mean is 67.4.

⇒ ∑y/28 = 67.4

⇒ ∑y = (67.4)(28)

⇒ ∑y = 1887.2

The total students in combined group = 36+28 =64

The sum of their scores =  ∑x + ∑y = 2707.2  + 1887.2 = 4594.4

The mean of the combined group = (∑x + ∑y)/64

The mean of the combined group = 4594.4/64 = 71.78

Step-by-step explanation:

Use the given times and velocities to make two points:  (1,4) and (2,2)   

Part A: 

Slope is the change in Y over the change in X from the two pints you made:

 Slope =  (2-4) / (2-1 )= -2

Now you have the slope, calculate the Y-intercept

y = -2x + b

Using (1,4)

4 = -2(1) + b = 4 =-2 +b. b = 6

 Equation is: y = -2x+6

Part B:

using the above equation replace x with 1, 2, 3, and 4 and solve for the Y

 then plot those onto a graph

A ship's navigator can keep the ship in safe waters by staying outside the 300-degree arc between two lighthouses and using the beams as navigational guides. Additionally, in areas with water breaks, navigators should account for wave diffraction to determine the safest angles for mooring.

To navigate safely and avoid the unsafe waters near the coastline marked by the 300-degree arc between two lighthouses at points A and B, a ship's navigator should use both lighthouses as reference points for establishing a safe navigational path. Typically, lighthouses are equipped with rotating beams, which can serve as a guide to determine a ship's position relative to hazardous areas. If the ship maintains a course outside of the direct line of sight between the two lighthouses, it can stay within the safe waters.

The navigator should also consider wave action when near a coastline or harbor entrance. If any breakwater structure or water break exists, such as a rock barrier with an opening, the navigator would need to be mindful of the wave patterns. As waves enter the opening, they diffract, and boats are generally safest at angles where the wave intensity is minimized.
