If you are given an equation of a line and a set of points, you should determine the slope of the equation that is perpendicular to the given equation of line. Lastly, you should use the set of points to write an equation for the perpendicular line.

Mathematically, the slope-intercept or standard form of the equation of a straight line is given by this mathematical expression;

y = mx + c

Where:

In Mathematics, a condition that must be met for two lines to be perpendicular is given by this mathematical expression:

m₁ × m₂ = -1

Assuming the given equation of a line is y = 2x, the slope of the equation that is perpendicular to this line would be calculated as follows;

m₁ × m₂ = -1

2 × m₂ = -1

Slope, m₂ = -1/2.

In conclusion, you will use the newly calculated slope alongside the set of points to determine the equation for the perpendicular line either by using the slope-intercept form or point-slope form.

Answer:

Step-by-step explanation:

The magnitude of the acceleration of the particle is zero when the velocity of the particle is zero.

What is Acceleration ?

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Given,

Velocity  v= x² − 5x + 4

now, the acceleration

a = dv/dt

​a = 2x (dx/dt) - 5x(dx/dt)

​

given that, v= dx/dt =0

so, a = 2x*0−5*0

a=0 m/sec²

so, the acceleration is zero ,when the velocity is zero.

Hence ,The magnitude of the acceleration of the particle is zero when the velocity of the particle is zero.

Answer:

R = (3, 14 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint M is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula

calculate the midpoint of PR using this formula and equate x and y coordinates to the coordinates of the given midpoint

let coordinates of R be (x, y ) and P = (- 15, 4 ) , then

[tex]\frac{x-15}{2}[/tex] = - 6 ( multiply both sides by 2 )

x - 15 = - 12 ( add 15 to both sides )

x = 3

and

[tex]\frac{y+4}{2}[/tex] = 9 ( multiply both sides by 2 )

y + 4 = 18 ( subtract 4 from both sides )

y = 14

the coordinates R = (3, 14 )

Answer:

x = 3.66

Step-by-step explanation:

Area of a rectangle = length * width

In this case:

(x+10)x = 50

x*x + x*10 = 50

x² + 10x - 50 = 0

x = {-10±√((10²) -(4*1*-50))} / (2*1)

x = {-10±√(10² + 200)} / 2

x = {-10±√(100+200)} / 2

x = {-10±√300} / 2

x = {-10±17.321} /2        aprox,

It is a geometric figure so only the positive value is taken.

x = {-10+17.321} / 2

x = 7.321/2

x = 3.66

Check:

3.66(3.66+10) = 50

The ordered pairs to the system of linear inequality are (-1, 5), (0, 4), (-6, 7)

A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.

In the problem given;

x + 5y > 8 ...eq(i)

4x - y < 6 ...eq(ii)

From eq(i)

x + 5y > 8

What is Percentage?

A percentage is a relative figure that represents the hundredth part of any amount. One percent (symbolised 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.

Solution:

To find the net/effective change we can the use the formula:

(a + b + ab/100)

here a and b are the rate of change

a = 25% and b = 20%

Net change = (25 +20 + 500/100) = 45 + 5 = 50%

Answer:

For the first one x= 60 degrees

Second one x= 125 degrees

Step-by-step explanation:

a) To figure out this we can see that the total of angles in a 5- angled shape is 540 degrees.

So (2x X 4) + x = 540 degrees

= 9x= 540

= x = 60

b) To figure out this we can see that the total of angles in a 7- angled shape is 900 degrees.

So 60+2x+x+x+x+x+90= 900

= 150 +6x= 900

= 6x= 750

= x= 125

To calculate how much money David will have in this account after 5 years, we first need to find out how much interest the account earns each year. To do this, we need to multiply the interest rate by the amount of money in the account. In this case, the interest earned each year would be $800 * 0.023 = $18.40.

Next, we need to calculate how much interest the account earns over the 5-year period. Since the interest is compounded semiannually, this means that the interest is earned twice per year. Therefore, the total amount of interest earned over 5 years would be $18.40 * 2 * 5 = $184.

Finally, we need to add the interest to the original amount of money in the account to find out how much money David will have after 5 years. In this case, the total amount of money David will have after 5 years is $800 + $184 = $984.

Therefore, if David keeps the money in this account for 5 years, he will have $984.

Step-by-step explanation:

These prime numbers are the ones.

2678 = 2 * 13 * 103

A prime number is a natural number that is greater than one and is not a product of smaller natural numbers. For example,  3 is a prime number and we can write it as a product, 1 * 3 or 3 * 1, which involves 3 itself.

So, prime numbers are those numbers that have only two factors, which are 1 and the number itself.

A natural number that is greater than 1 and is not a prime number, is called a composite number. Every natural number which is greater than 1, is either a prime itself or can be factorized as a product of primes that is unique up to their order.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles. It is used to calculate lengths, angles, and other geometric figures. Trigonometry has applications in many fields, including engineering, astronomy, and navigation. The most common trigonometric functions are sine, cosine, and tangent. These functions are used to solve problems related to triangles, circles, and other geometric figures. Trigonometric identities are also used to solve algebraic equations. Trigonometry is an important tool for studying the physical world, as it allows us to calculate the position and motion of objects in space.
