The change that increases the loudness is a > 1

From the question, the equation of the function that represents the musical note is given as

y = a sin(1320πx)

Where

In sound, the sound loudness is directly proportional to the amplitude.

This means that an increment in the amplitude, would cause the note to become louder

This change is represented as a > 1

This is so because a represents the amplitude, and the initial value is 1

She invested $2,400 in the 2.5% account and $3,600 in the 4% simple interest account

Here, we want to know the amount of money invested in each account

Let the amount invested in the 4% simple interest account be $x ----> (a)

While the amount invested in the 2.5% account be $y -------->(b)

So mathematically;

Both the interests are added to get total interest

x + y = 6,000 ••••••(i)

Let’s now evaluate the interest

for the 4% account , interest = 4/100 * x = 4x/100

For the 2.5% account, interest = 2.5/100 * y= 2.5y/100

The addition of both  interests gives the total simple interest;

4x/100 + 2.5y/100 = 204

Multiply through by 100

4x + 2.5y = 20,400 •••••••(ii)

From i, x = 6,000 - y

Putting this into equation ii

4(6,000-y) + 2.5y = 20,400

24,000 - 4y + 2.5y = 20,400

24,000-20,400 = 4y - 2.5y

1.5y = 3,600

y = 3,600/1.5

y = $2,400

Recalling it again,

x = 6000 - y

x = 6,000 - 2,400

x = $3,600

Therefore, Nina invested $2,400 in the 2.5% account and $3,600 in the 4% simple interest account

The length of the original sides of the rectangle are 72m and 24m.

The area of a rectangle formula is used to calculate the area occupied by the rectangle within its boundaries. A rectangle's area is calculated by multiplying its length and breadth.

Given:

One side is 3 times as long as the other in a rectangle.

Let the length of the rectangle be 3x and the breadth of the rectangle be x.

Area of original rectangle = length × breadth

                             = 3x² m²

Now, the longest side is extended by 4m.

Length of rectangle = 3x + 4

Area of rectangle = length × breadth

                             =  x(3x + 4) m²

It is given that this area will be 96 square meters larger than the former.

So, x(3x + 4) - 3x² = 96

⇒ 3x² + 4x - 3x² = 96

⇒ 4x = 96

⇒ x = 24 m

Original length of the rectangle = 3x = 3×24 = 72m

Therefore, the original length of the rectangle is 72m and the original breadth of the rectangle is 24m.

Given the circle, we can see the following facts:

Diameter= 24 ft ----> radius= 12 ft

Total arc length = 360°

The arc of a semi-circle is equal to 360/2 = 180 degrees

The red labeled arc is given by the difference between 360, the other 60 degrees and the semi-circle,

360° - 180° - 60° = 120°

So, representing this as a radian form:

Simplifying:

So, the answer is 8π ft

The value of BC is 60.6.

According to the segment addition postulate, if we have two locations on a line segment, A and C, a third point B lies on the line segment AC if and only if the lengths between the points match the requirements of the equation AB + BC = AC.

Given:

BC = 6x+6

AB = 8x+9  

AC = 142

We need to find BC.

As AB and BC combine to form AC, we add them together and equate them with the value of AC to determine the value of x.

Using the property of segment addition,

AB + BC = AC

8x + 9 + 6x + 6 = 142

Combine the variable terms and constants together,

14x + 15 = 142

14x = 142 - 15 (Subtracting both sides by 15)

14x = 127

x = 9.1

Hence the value of BC is,

BC = 6x + 6 = 6(9.1) + 6 = 60.6

If the sum of two angles is 180 then the angles are supplementary.This is true.

Supplementary angles are those that total 180 degrees. Angles 130° and 50°, for example, are supplementary angles since the sum of 130° and 50° equals 180°.

If the total of two angles is 180 degrees, they are considered to be supplementary angles since they form a linear angle when combined. If the total of two angles is 90 degrees, they are considered to be complimentary angles since they produce a right angle when combined.

If two angles add up to 180 degrees, they are considered to be supplementary angles in geometry. For example, if A + B = 180°, A and B are referred to as supplementary angles. When supplementary angles are combined, they always yield a straight angle (180 degrees).

Answer:

x = 400

Step-by-step explanation:

x + 146 = 546

We need to subtract 146 on both sides.

146 - 146 is equal to 0 so we cancel out. 546 - 146 is equal to 400.

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line = (1, -2)

A network of tissues, blood arteries, and organs called the lymphatic system collaborates to transport lymph, a colorless, watery fluid, back into your circulatory system. Every day, your body's arteries, smaller arteriole blood vessels, and capillaries circulate about 20 liters of plasma.

The right lymphatic duct receives drainage from the right cervical node. The thoracic duct receives drainage from the superficial popliteal, superficial inguinal, and lumbar nodes. The sides and back of the neck include the cervical lymph nodes.

Explanation:

If has 176 £1 coins then 176 drivers paid £1 and 20 p coins.

The rest of the driver paid with 20 p coins.

So the number of 20 p coins is:

320 - 176 = 144

Since £1 and 20 p need 6 coins of 20 p, the number of drivers who paid only for 20 p coins is:

144 / 6 = 24

The total number of drivers is:

176 + 24 = 200

The expression for volume is (28-2x)(22-2x)x and when x=6, the volume is 840 inch^3.

A 3D object's volume is the amount of actual space it occupies. It is a 2D shape's 3D equivalent of area. It is quantified in cubic units like cm3. It means that the amount of space a closed form can occupy in three dimensions depends on its volume. Volume is a gauge of a thing's potential. For instance, a cup is said to have a 100 ml capacity if the brim can hold 100 ml of water. Another way to measure volume is the amount of space a three-dimensional item takes up.

According to question,

Let x be the height of the cubic box

Length = (28-2x)

Breadth = (22-2x)

Volume = x(28-x)(22-x)

Answer:

The biker's pace is 25 miles per hour and the walker's speed is 50/3 miles per hour.

Answer:The speed of the walker is 16.67 miles per hour.

The speed of the cyclist is 25 miles per hour.

How to calculate the value?

Let the speed of a walker = x

Biker's speed = 1.5x

Their relative speed will be:

= 1.5x - x = 0.5x

Distance between them = 12.5 miles

Time taken = 1.5 hours.

It should be noted that distance will be:

= Speed × Time

12.5 = 1.5 × 0.5x

Divide through to get x

12.5 = 0.75x

x = 16.67 miles per hour.

Speed of cyclist = 16.67 × 1.5 = 25 miles per hour.

y = 6m - 13

Step-by-step explanation:

Parallel lines have the same slope.  The slope in the equation y = 6x -2 is 6.

To write an equation in the slope intercept form, we need a slope and a y-intercept.  We have the slope, we need to find the y-intercept.

To find the y intercept, we need a slope, and x on the line and a y on the line.  The point (3,5) gives us the x and the y.

slope = 6

x = 3

y = 5

y = mx + b  plug in what we know and solve for b

5 = 6(3) + b

5 = 18 + b  Subtract 18 from both sides of the equation

-13 = b

y = mx  + b

y = 6m - 13

Trina is closer to the surface of the ocean. She will not fly higher than Jessie did.

Consider the provided information.

The distance is the absolute value of a number.

Part (A) : It is given that Trina went scuba diving and reached an elevation of -85.5 meters, which is below sea level.

That means the distance she covers is: |-85.5| = 85.5 meters

Thus Trina covers 85.5 meters.

Jessie went hang gliding and reached 87.9 meters which is above sea level.

That means the distance she covers is: |87.9| = 87.9 meters

We know that 85.5 < 87.9

So, we can say that Trina is closer to the surface of the ocean as she covers less distance.

Part (B) : Trina wants to hang glide at the same number of meters above sea level as she scuba dived below sea level.

That means she will hang the glide at a height of 85.5 meters.

As we know 85.5 < 87.9

Thus, she will not fly higher than Jessie.
