Answer:

The new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).

i.e. [(-4,0)→(4,0)]

Step-by-step explanation:

The rule for rotation a point 180° counterclockwise about the origin states that when a point (x, y) is rotated 180° counterclockwise about the origin, the new position of the coordinates of point P(x, y) becomes (-x, -y).

Hence,

So, when the given point  (-4,0) is rotated 180 degrees counterclockwise using center (0,0), the new coordinates of the image will be:

Therefore, the new coordinate of the image will be (4, 0) when the point (-4,0) is rotated 180 degrees counterclockwise using center (0,0).

i.e. [(-4,0)→(4,0)]

Answer: at new cost increase is 30%

               after additional $4.50 fee  increase  would be 45%

Step-by-step explanation:

use equation

30:100=39:x

30x=3900

x=3900/30

x=130

130-100=30%

39+4.50=43.5

30:100=43.5:x

30x=4350

x=4350/30

x=145

145-100=45%

The increase percent will be 30%

And, The percent increase if the ticket agent charges an additional​ $4.50 fee with the new ticket​ price is 45%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The old cost of the tickets = $30

And, New cost of the ticket = $39

Now,

The increase percent is calculate as;

Increase percent = (39 - 30) / 30 x 100

                           = 9/30 x 100

                           = 30%

And, When the ticket agent charges an additional $4.50 fee with the new ticket price.

Then, The new cost of the tickets = $39 + $4.50

                                                    = $43.50

Thus, The percent increase if the ticket agent charges an additional $4.50 fee with the new ticket price is calculated as;

Increase percent = (43.50 - 30) / 30  x 100

                          = 13.50/30  x 100

                          = 45%

Therefore, The increase percent will be 30%.

And, The percent increase if the ticket agent charges an additional​ $4.50 fee with the new ticket​ price is 45%.

Step-by-step explanation: since he has 24

Yaneliz has 24 X 1/6 = 4

Answer: y = 24 x 1/6

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Marcos: $24

Yaneliz: 1/6 of the amount of money Marcos has

So, to write an expression we have to multiply the amount of money Marcos has (24) by 1/6.

Mathematically speaking

Y = 24 x 1/6  

Where "y" is the amount of money Yaneliz has.

Solving:

24 x 1/6 = 4

Yaneliz has $4.

Final answer:

To form the quadratic equation, we consider the original time to cover 6 km at speed v km/h and the new time at speed (v+2) km/h, then equate the difference in time to 4 minutes. Solving for v using a common denominator and simplifying, we obtain the quadratic equation 15v^2 + 30v - 90 = 0.

Explanation:

To form a quadratic equation from the given scenario, we’ll first define the relationship between distance, speed, and time. The time taken to travel 6 km at the original speed v km/h is distance divided by speed, which is 6/v hours. If Wanni increased her speed by 2 km/h, her new speed would be v + 2 km/h, and the new time taken would be 6/(v+2) hours.

We are told that by increasing her speed, Wanni arrives 4 minutes earlier. Since 1 hour is 60 minutes, 4 minutes is 4/60 or 1/15 hours. We can now set up an equation relating the difference between the two times to 1/15 hours:

6/v - 6/(v+2) = 1/15

To solve for v, we first find a common denominator for the fractions on the left side of the equation, which is v(v+2). Multiplying both sides by the common denominator, we get:
6(v+2) - 6v = v(v+2)/15

Expanding the terms and moving everything to one side of the equation, we get our quadratic equation in terms of v:

15v2 + 30v - 90 = 0

26. irrational

Step-by-step explanation:

A rational number is a number that can be written as a fraction. It may have decimals that end or repeating decimals.

An irrational number cannot be written as a fraction. It's decimals continue on and do not repeat.

25.

When you multiply two rational numbers, the product is rational. The square root of 16 is 4, which is rational because it is a whole number. 4/7 is written as a fraction so it is rational.

26.

The square root of 2 is an irrational number because its decimals go on and do not repeat. 7 is a whole number so it is rational. Subtracting a irrational number from a rational number gives an irrational number.

Answer:

The volume of the larger solid is [tex]592.6\ mm^3[/tex]

Step-by-step explanation:

The question is

If these solids are similar, find the volume of the larger solid

step 1      

Find the scale factor

we know that

If two solids are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

x ----> the height of the larger solid in mm

y ----> the height of the smaller solid in mm

z ---> the scale factor

[tex]z=\frac{x}{y}[/tex]

we have

[tex]x=4\ mm\\y=3\ mm[/tex]

substitute

[tex]z=\frac{4}{3}[/tex] ---> scale factor

step 2

Find the volume of the larger solid

we know that

If two solids are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

x ----> the volume of the larger solid in cubic millimeters

y ----> the volume of the smaller solid in in cubic millimeters

z ---> the scale factor

[tex]z^3=\frac{x}{y}[/tex]

we have

[tex]z=\frac{4}{3}[/tex]

[tex]y=250\ mm^3[/tex]

substitute the values

[tex](\frac{4}{3})^3=\frac{x}{250}[/tex]

solve for x

[tex](\frac{64}{27})=\frac{x}{250}[/tex]

[tex]x=250(\frac{64}{27})[/tex]

[tex]x=592.6\ mm^3[/tex]

Answer:

Step-by-step explanation:

sin ^2x + cos ^2 x = 1, so

cos^2x = 1 - (5/11)^2 = 96/121

cos x = √96/11

= 4√6/11.

sin 2x = 2 sinx cosx  = 2 * 5/11 * 4√6/11.

= 40√6/121.

cos2x =  2cos^2 x - 1

= 2 * 96/121 - 1

=  192/121 - 121/121

= 71/121.

Answer:

The initial value of the function is 3.

The range of the function is y > 0.

The simplified base value of the function is 8.

Step-by-step explanation:

The given function is [tex]f(x) = 3(16)^{\frac{3}{4}x }[/tex]

Therefore, the simplified function will be [tex]f(x) = 3(16^{\frac{3}{4} } )^{x} = 3(8)^{x}[/tex] ........ (1)

Now, at x = 0, f(x) = 3.

Hence, the initial value of the function is 3. (Answer)

The value of x in the equation (1) can be any real value but for any value of x, the f(x) value will be greater than 0.

Hence, y > 0 that is the range that the function has. (Answer)

Again, from equation (1) we get the simplified base value of the function is 8. (Answer)

The sum of slopes b and c is 0

This statement is NOT always true

Step-by-step explanation:

(1) According to the graph, line a and b are parallel to each other. This, therefore, means that they have the same slope/gradient.

(2) Line c however, is perpendicular to both lines a and b. The slope of two lines that are perpendicular to each other is always the negative inverse of the slope of the other. This means that the product of their slopes will become -1.

An example is that if the slope of a line is 2, then a line perpendicular to it will have a slop of – ½
