It is also called as the constant of proportionality. It is also called as the constant of proportionality. *

Answers

Answer 1

Answer:

constant of variation

Step-by-step explanation:

Constant of variation and constant of proportionality mean the same and they are used in variations.

For instance:

[tex]y = 2x[/tex]

In the above equation, y varies directly as x and the constant of proportionality or variation is 2.

It is often represented with k (though, other alphabets can also be used)

Double 8 means to do 8 x 2 and you also need to do 4x2. In the end you need to subtract the two numbers so you need brackets.

This means (8x2)-(4x2) is the correct answer!!

Hope this helps :)

Answer:

The last one

Step-by-step explanation:

This is because 8x2 is doubling8 and then it also asks to multiply 4 and 2

Lastly it says subtract second number from first which means subtract 4 by 2 from 8 by 2

I am working of Circumference of circles rn and How do u find the Circumference of a circle if there is no circumference?

Answers

Hi, I’d need to see the specific question.
circumference=pie x diameter

Step-by-step explanation:

you need either:

the diameter- the distance from one side to the other, or

the Radius- the distance from the center to the edge

the diameter is always double the radius, and accordingly the radius is always half the diameter.

so, the circumference ca be figured out by multiplying the diameter times pi- which, for most calculations is 3.14

if you only have the radius, multiply that by 2 to get the diameter, then by 3.14.

hope that helps!

According to the discriminant of the quadratic equation, it will have equal roots for p = -16.

What is the discriminant of a quadratic equation and how does it influence the solutions?

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

The solutions are as follows:

If [tex]\mathbf{\Delta > 0}[/tex], and it is a perfect square, it has 2 rational solutions.If [tex]\mathbf{\Delta > 0}[/tex], and it is not a perfect square, it has 2 irrational solutions.If [tex]\mathbf{\Delta = 0}[/tex], it has equal roots.If [tex]\mathbf{\Delta < 0}[/tex], it has 2 complex solutions.

In this problem, the equation is:

[tex]f(x) = -x^2 + 8x + p[/tex]

Hence the coefficients are a = -1, b = 8, c = p.

It has equal roots if [tex]\Delta = 0[/tex], hence:

[tex]b^2 - 4ac = 0[/tex]

[tex]8^2 + 4p = 0[/tex]

[tex]4p = -64[/tex]

[tex]p = -16[/tex]

Answer:

Equation of the line in point-slope form: y - 5 = -⅚(x - 2)

Equation of the line in slope-intercept form: y = -⅚x + 20/3

Step-by-step explanation:

Equation of a line can be expressed in the point-slope form as y - b = m(x - a), where,

m = slope = -⅚

a = 2

b = 5

Substitute the values into y - b = m(x - a):

y - 5 = -⅚(x - 2) => point-slope form.

We can rewrite this in the slope-intercept form, such as:

Multiply both sides by 6

6(y - 5) = -5(x - 2)

6y - 30 = -5x + 10

6y - 30 + 30 = -5x + 10 + 30

6y = -5x + 40

Divide both sides by 6

y = -5x/6 + 40/6

y = -⅚x + 20/3
