Centroid at___

Answer:

a) 5

b) -4/3

c) y = -4/3x - 11/3

Step-by-step explanation:

The length of the segment means the length in between two points. Use 2 dimensional distance formula.

[tex]d = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2 }[/tex]

Plug in your points.

x value is the first point in the set, the horizontal measure in units.

y value is the second point in the set, the vertical measure in units.

x values of 2 points: -2, -5

y values of 2 points: -1, 3

[tex]d = \sqrt{(-5--2)^2 + (3--1)^2 }[/tex]

A negative value subtracted by another negative value is the first negative value plus the inverse of the second negative value.

For example,

-5 - -6 = -5 + 6 = 1

Simplify.

[tex]d = \sqrt{(-3)^2 + (4)^2 }[/tex]

[tex]d = \sqrt{9 + 16}[/tex]

[tex]d = \sqrt{25}[/tex]

5

Square root of 25 is 5 because 5^2, which is 5 x 5 is 25.

The slope is how much the y-value changes when the x-value increases by 1.

To calculate this, plug your points into the slope formula.

[tex]Slope = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{3--1}{-5--2}[/tex]

[tex]\frac{4}{-3}[/tex]

-4/3

I'm going to assume that the problem is asking you to write it in the form of y=mx+b, or slope-intercept form, a way of easily graphing a line. If it  is asking you to express it in another way like Standard or Point-Slope Form, comment and I'll change it.

y = mx+b

m = slope

b = y-intercept, or the y-value of when the x-value is 0 on a line

y and x stays as variables if you want to graph it and for generally answering problems.

So, if x = 0, we can plug it into what we currently know.

We know the points: (-2,-1) or (-5,3)

Plug in either set of points into the slope-intercept equation.

I'll use -2,-1 but you can use either.

-1 = (-4/3) (-2) + b

Because we're solving for when x is 0, replace -2 for 0.

-1 = 8/3 + b

Subtract 8/3 on both sides.

-1 - 8/3 = 8/3 - 8/3 + b

-1 - 8/3 = b

b = -11/3

Now, the equation is:

y = -4/3x - 11/3

This is the beauty of the forms of linear equations. You can plug in any points to solve for the full set of points. You can convert any form of the linear equation to another form.

According to the given statement the answer of angle A is  [tex]\mathrm{m} \angle A=65^{\circ}[/tex].

A parallelogram with the opposing sides perpendicular is called a quadrilateral (and therefore opposite angles equal). A parallelogram among all right angles generally known as a rectangle, whereas a quadrilateral having equal angles is known as a rhombus.

[tex]\mathrm{m} \angle F G D=35^{\circ}\\\mathrm{m} \angle DFG=180^{\circ}-69^{\circ}\\\\[linear pair of angle]\\mathrm{m} \angle DFG=111^{\circ}\\\mathrm{m} \angle F DG=180^{\circ}-(35^{\circ}+111^{\circ})\\\\mathrm{m} \angle F DG=34^{\circ}[/tex]

because DC||AB, so  

[tex]\mathrm{m} \angle BDC={m} \angle ABD=Alternate angle[/tex]

[tex]so, \mathrm{m} \angle ABD=34^{\circ}[/tex]

because the sum of interior angle of a triangle = 180

[tex]so, \mathrm{m} \angle A=180^{\circ}-(81^{\circ}+34^{\circ})\\ \mathrm{m} \angle A=65^{\circ}[/tex]

Answer:

$0.27875 or $0.28 1 cup = 2 ounces Number of cups in 1 jar = 4 ounce

Step-by-step explanation:

The equations on the graph have no solution

From the question, we have the following equations that can be used in our computation:

y = -3(x - 1)

y = -3x - 1

Also, we have:

The lines are parallel to each other.

As a general rule:

Parallel lines are lines that do not intersect and they have the same slope

Because the lines do not intersect, it means that the system do not have any solution

Answer:

c=-35/4

Step-by-step explanation:

For this, we would use Vieta's theorem, which states the roots of the equation added together would equal -b/a, x₁ + x₂ = -b/a

Lets create a system with this:
x₁ - x₂ = 6 (This is given from the problem)

x₁ + x₂ = -b/a  or -1/1, plugging in the values from your equation

next, we would add these systems together

x₁ + x₂ + (x₁ - x₂) = 6 + (-1)
x₁ + x₁ = 5
2x₁ = 5

x₁ = 2.5

If we plug x₁ back in, we get:

2.5 - x₂ = 6

-x₂ = 3.5

x₂ = -3.5

Now that we have the roots, we can use Vieta's theorem again to say

x₁ * x₂ = c/a

Plugging this in, we get:

2.5 * -3.5 = c/a

Lets change things to fractions to make things easier

5/2 * -7/2 = c/a

Plugging in a, we get

-35/4 = c/1

-35 = 4c

c = -35/4

Hope this helps!

As a general rule, the y-intercept is the point in an equation or a function where x = 0

Using the above as a guide, we have the following:

For the function g(x), we have

g(x) = abˣ

Using the given points (1, -2) and the growth factor of 2, we have

g(x) = a(2)ˣ

This means that

a(2)¹ = -2

So, we have

2a = -2

a = -1

So, the equation is

g(x) = -1(2)ˣ

Set x = 0

g(0) = -1(2)⁰

g(0) = -1

So, the y-intercept of function g(x) = -1

When a population is subjected to directional selection over time, the traits that are selected for will remain stable while the traits that are selected against will disappear.

Evolution is the study of how populations change over time. Most traits have multiple genes controlling their structure, function, appearance, and other characteristics. Single genes only very infrequently control a trait.

As a result, most traits have a tendency to be continuous in nature and to have a wide range of values. One side of these values will be picked against during directional selection, while the other side will be selected in favor of. Look at the illustration of a lemur's fur color below.
