Find the distance between points M and N.<br>M= (3,-2)<br>N= (5,-6)

MaRussiya [10]

Answer:

12

Step-by-step explanation:

The formula for distance between points is $\sqrt{(x.2-x.1)^{2} +(y.2-y.1)^{2}$

So when you inserts the coordinates in this formula, it would be $\sqrt{(-2-3)^2+(-6-5)^2}$

$\sqrt{(-5)^2+(-11)^2}$

$\sqrt{25+121}$

$\sqrt{146}$

=12.08305

Usually, distance is round to whole number. So, it would be 12

How do I do a question 5* “I, J, k, and L

7nadin3 [17]

Answer:

Step-by-step explanation:

5 (i) 243 ÷x = -81

243 ÷ -81 = x

x = -3

5 (j) 50 ÷ x = -50

50 ÷ -50 = x

x = -1

5(k) -92 * x = 184

x = 184 ÷ -92

x = -2

5(l) -800 ÷x = -20

-800 ÷ -20 = x

x = 40

Which of the graphs best represents a system of equations that has no solution?

Lesechka [4]

When the lines are parallel then there is no solution to the system of equations.
This happens because the intersection is the solution. And when there is no intersection then there is no solution.

Solve the triangle A=21 C=105 c=5

gregori [183]

Answer:

Granted that uppercase letters are the angles measurements and lowercase letters are the side lengths. I also was unable to round as I don't know to what decimal you need to round to.

First to find the measure of angle B, we must subtract A and C from 180

$180-21-105=54$

B=54

Next, we can use the law of sines in order to find the measures of a and b

As a reminder, The law of sines is

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

First, lets solve for b

$\frac{b}{sin54}=\frac{5}{sin105} \\\\b=\frac{(5)sin54}{sin105}\\\\b=4.187780119$

Next lets solve for a

$\frac{a}{sin21}=\frac{5}{sin105} \\\\a=\frac{(5)sin21}{sin105}\\\\a=1.85504901$

Find the perimeter of the figure to the nearest hundredth.<br><br><br> Ps: it is not 30

frutty [35]

Answer:

Perimeter = 36.8 ft

Step-by-step explanation:

<u>Step 1: Add the straight sides together</u>

3+3+3+3+3+3 = 18 ft

<u>Step 2: Find the perimeter of the semi-circles</u>

The formula for the perimeter of semi-circle: 1/2 π × d

Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.

Now, 1/2π * 6 = 9.4 ft

But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft

<u>Step 3: Add all of them</u>

18 + 18.8 = 36.8 ft
