Find the midpoint of the line segment with end coordinates of: ( − 2 , − 4 ) and ( 2 , − 10 )

Answer:

5.83 units

Step-by-step explanation:

See attached picture.  You can use the Pythagorean Theorem.  I added some lines to show the legs of a right triangle.  AB is the hypotenuse.

[tex]3^2+5^2=(AB)^2\\\\9+25 = (AB)^2\\\\34=(AB)^2\\\\AB=\sqrt{34} \approx 5.83[/tex]

Answer:

5.83

Answer:

dependent variable

Step-by-step explanation:

from what i have seen this is the right choice heres an example of how i came up with it you can decide off of this

Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). ... Example: Your test score affects how long you sleep.

Answer:

Round to the nearest tenth. The diagram is not drawn to scale. Solution: We know that. cosθ = adjacent/hypotenuse. Substituting the values. cos22 = x/11.

Problem 1

x = measure of angle N

2x = measure of angle M, twice as large as N

3(2x) = 6x = measure of angle O, three times as large as M

The three angles add to 180 which is true of any triangle.

M+N+O = 180

x+2x+6x = 180

9x = 180

x = 180/9

x = 20 is the measure of angle N

Use this x value to find that 2x = 2*20 = 40 and 6x = 6*20 = 120 to represent the measures of angles M and O in that order.

====================================================

Problem 2

n = number of sides

S = sum of the interior angles of a polygon with n sides

S = 180(n-2)

2700 = 180(n-2)

n-2 = 2700/180

n-2 = 15

n = 15+2

n = 17

====================================================

Problem 3

x = smaller acute angle

3x = larger acute angle, three times as large

For any right triangle, the two acute angles always add to 90.

x+3x = 90

4x = 90

x = 90/4

x = 22.5

This leads to 3x = 3*22.5 = 67.5

Answer:

x = 147

Step-by-step explanation:

all angles add up to 360

80 + 95 + 38 + x = 360

If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations. the intersection points (-3,3) Since the system is infinite it means there is 1 line on the graph-

Step-by-step explanation:

The solution (infinitely many solutions) in this case means the runners are at the same place at any point in time.

When a set of linear equations has a single solution,

In the case of coinciding lines with the same y-intercept, the number of solutions to the equation system is unlimited. The two lines are actually in the same line if they share the same slope and y-intercept.plied set then has a special solution.

We have two runners racing against each other.

The two equations form a system that has infinitely many solutions.

Thus, the solution (infinitely many solutions) in this case means the runners are at the same place at any point in time.

Answer:

16

Step-by-step explanation:

We know the midline is

(5.2,7)

And the minimum is (1.2,1.2)

Note that the distance from the midline to minimum or max is 1/4 the distance of the period.

The period is respected to x so only look at the the x values.

So

Step 1: Find the distance from minimum point and midline.

[tex] |5.2 - 1.2| = 4[/tex]

Step 2: Multiply that by 4

[tex]4 \times 4 = 16[/tex]

So the period is 16.

The constant of proportionality of the equation is 29.4

If the amount of money an accountant makes, m, is directly proportional to the time taken, this is expressed as:

m = kh

where;

k is the variation constant

Given that the amount of money an accountant makes, m, for working h hours is represented by the equation m = 29.4h, the variation constant is calculated as:

29.4h = kh

k = 29.4

Hence the constant of proportionality of the equation is 29.4

I think the answer would be 2x2y 2xy x2 xy

Step-by-step explanation:

Hope this helps sorry if I am wrong.

Let's call one ratio = x

So, the sides are 3x, 5x and 7x respectively.

Since the perimeter is 90 cm, the sum of 3 sides = 90 cm

-> 3x + 5x + 7x = 90 cm

-> 15x = 90cm
-> x = 6cm.

So, the 3 sides are 3x6, 5x6 and 7x6 -> 18,30 and 42.

Recheck : 18 + 30 + 42 = 90

18:30:42 = 3:5:7 (all divided by 6)

use pythag theorum you get 11.7 i thinkkk

Step-by-step explanation:

Try creating a triangle using the length of x and the length of y, so, you can tell the line goes from -5 to 5 on the x axis so that means its 10 long on x and 0 to 6 on y axis so its 6 long on y... then create a triangle and use the pythagorean theorem (the square root of (10 squared + 6 squared) which is around 11.7 .... i think, hope that helps! -prowl

Answer:

h = 20 km

Step-by-step explanation:

Mario's path forms a right triangle with legs 16 km and 12 km and hypotenuse h. Let's use the Pythagorean Theorem (a² + b² = c²) to solve for h.

16² + 12² = h²

256 + 144 = h²

400 = h²

h = 20 km

Answer:

[tex]\frac{1}{30}[/tex]

Step-by-step explanation:

Separate into Case 1 and Case 2:

Case 1: We want a yellow marble

There is only 1 yellow marble out of the 6 marbles.

Probability for a yellow marble = [tex]\frac{1}{6}[/tex]

Case 2: We want a blue marble

There is only 1 blue marble out of the 5 marbles remaining. (We took 1 yellow marble out already)

Probability for a yellow marble = [tex]\frac{1}{5}[/tex]

Multiply Case 1 with Case 2 because they are a combination:
