7.5cm distance a spring when a force of 270 newtons stretch the same spring.

A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Given Data

A force of 180 newtons stretches a spring 5 cm

If we consider F to be the force and x to be the extension, then:

F = kx

F = 180

x = 5

Equating

180 = 5k

k = 36

F = 36x

Force of 270:

270 = 36x

x= 7.5

7.5cm distance a spring when a force of 270 newtons stretch the same spring.

be alert m represents the MIDPOINT.

THE MIDPOINT IS (0,4)

Answer:

-1/7

Step-by-step explanation:

The inequality expression given as |-4/3x - 5| > 19 has a solution of 10.5 < x < -18

From the question, the inequality is given as

|-4/3x-5|>19

Rewrite properly as

|-4/3x - 5| > 19

Remove the absolute bracket

So, we have the following representation

-19 > -4/3x - 5 > 19

Add 5 to all sides of the inequality

So, we have

-14 > -4/3x > 24

Multiply through by -3/4

So, we have

10.5 < x < -18

Hence, the solution to the expression is 10.5 < x < -18

The exponential function that shows the amount of money paid for membership x months after the beginning of the year is given by y = 32(1.18)ˣ.

There are two possibilities for the exponential function: it can be increasing or decreasing. Being increasing means that as the value of x increases, the value of f(x) also increases; being decreasing means that as the value of x decreases, the value of f(x) also decreases.

Let y represent the amount of money paid for membership x months after the beginning of the year. Abby's gym membership will increase by 18% a month. This is an exponential function.She is currently paying $32 a month, hence:y = 32(1 + 0.18)ˣy = 32(1.18)ˣ

The value of t for the angles of the given triangle will be 30.67.

The straight angle is equal to the total of the angles of a triangle. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle. For a very long period, it was unknown if there were any alternative geometries for which the total is different.

The triangle has three sides and is a two-dimensional figure having the sum of the angles of 180 degrees.

In the given image the three angles are 2t, t + 8, and t - 12. The value of t will be calculated as:-

2t + t + 8 + t - 12 = 180

4t - 4 = 180

4t = 184

t = 184 / 4

t = 30.67

x = -14/9 is the solution to the equation ( 7x + 6 )/4 = ( 2x − 3 )/5 in a simplified improper fraction form.

Given the data in the question;

To solve for x, first we cross multiply

( 7x + 6 )/4 = ( 2x − 3 )/5

5( 7x + 6 ) = 4( 2x − 3 )

Remove the parenthesis using distributive property

7x×5 + 6×5 = 2x×4 − 3×4

35x + 30 = 8x - 12

Collect like terms by moving all terms containing x to the left and all constant terms to the right side of the equation.

35x - 8x = -12 - 30

27x = -12 - 30

27x = -42

Divide both sides by 27

27x/27 = -42/27

x = -42/27

x = -14/9

Answer:

2/3

Step-by-step explanation:

Using the rule for a dilation, it is found that:

1. The table with the coordinates is given by the first image.

2. The graph of the dilated triangle is given by the second image.

3. The rule is: (x,y) -> (1.5x, 1.5y).

When a figure is dilated by an scale factor of a, each vertex of the figure is multiplied by the scale factor of a, hence the rule is given by the following vector:

(x,y) -> (ax, ay).

The coordinates of the vertices of the pre-image are given as follows:

A(-2, -2), B(2,2), C(4, -2).

The dilation has a scale factor of 1.5, hence the rule for the calculation of each vertex of the image, considering the pre-image, is given as follows:

(x,y) -> (1.5x, 1.5y).

Then the vertices of the image will be given as follows:

A'(-3, -3), B'(3,3), C'(6, -3).

Each coordinate of A, B and C was simply multiplied by 1/2, and the triangle with these vertices is given by the second image at the end of the answer.

The launching angle of the plane which has reached a height of 35000 ft is 15°

Let the distance travelled by the airplane horizontally be AB

The height reached by the airplane be BC

Thus AB = 130000 ft

        BC = 35000 ft

The launching angle of the airplane can be found using the formula

                                   tanθ = opposite / adjacent

                                                    (or)

                                           tanθ  = BC / AB

Let us substitute the known values in the above equation, we get

                                          tanθ  = 35000/130000

                                          tanθ  = 0.2692

                                               θ  = tan⁻¹ (0.2692)

Answer: 14 : 12

Step-by-step explanation:

Answer: 14:12

Step-by-step explanation: To find the ratio, you would either multiply or divide the two numbers by the same number, and you would get a simplified ratio or an equivalent one. Because 7:6 is simplified, we have to find an equivalent ratio, meaning we multiply. If we multiply 7 by two, we get 14. Multiply 6 by two to get 12. So, the answer is 14:12. Divide both 14 and 12 by two to get back to 7:6.

The value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.

A straight line of the form  y = MX + c has its slope as 'm'

It is constant for a line. The more the slope is, the steeper the line is.

Sign convention takes bottom left to top right going line as positive sloped. And that line which goes from bottom right to top left is taken to have a negative slope. The horizontal line has 0 slopes and the vertical line has an infinite slope, as it is now at maximum steepness.

We have been given the equation cx+4y=12 which has a slope of  8.

Also cx+4y=12

4y = 12 - cx

y = 12/4 - cx/4

y = 3 - cx/4

Then we know that straight line of the form  y = mx + c

By comparing the formula;

y = 3 - cx/4

Slope = c/4 = 8

c/4 = 8

c = 8(4)

c = 32

Therefore, the value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.

An irrational number that lies between the two given ones, 0.6333.... and 0.64 is:

√7 - 2.01 =0.63575...

Remember that an irrational number is a number that can't be written as the quotient between two integers.

Here we want to find two numbers between 0.6333 (where the 3 repeats infinitely) and 0.64

So we cold try to find a number like:

6.3349412490184...

Such that there is no pattern (because if there were a pattern, it would not be an irrational number).

An example of this can be, for example:

√7 = 2.64575...

This is an irrational number.

Now, if we subtract 2.01 from that we will get:

√7 - 2.01 = 2.64575... - 2.01 = 0.63575...

This is an irrational number and lies between the two given ones, then we conclude that √7 - 2.01 =0.63575... is a correct option.

Let's write everything in slope-intercept format of y=mx+b, where m is the slope and b is the y-intercept.

x+3y=15

3y= -x + 15

y = (-1/3)x + 5

Parallel lines will have the sam slope, in this case -(1/3),  So the new line will be:

y = (-1/3)x + b

We need to fijnd a value of b that will force the ine through point (6,1).  Enter (6,1) in the equation and solve for b:
