Find the perimeter of triangle ABC with vertices A(6, 3), B(6, - 2) , and C(- 4, 3) .

Answers

Answer:

26.2 units

Step-by-step explanation:

We are given the points/vertices

A(6, 3),

B(6, - 2) , and

C(- 4, 3)

Step two

Let us find the distances between the given points/vertices

A-B =A(6, 3) to B(6,-2)

d=√((x2-x1)²+(y2-y1)²)

Substitute

d=√((6-6)²+(-2-3)²)

d=√(-2-3)²)

d=√(-5)²)

d=5 units

B-C=B(6, - 2) to C(-4, 3)

d=√((x2-x1)²+(y2-y1)²)

Substitute

d=√((-4-6)²+(3+2)²)

d=√(-10)²+(5)²)

d=√100+25

d=√125

d=11.2 units

C-A=C(-4, 3) to A(6, 3)

d=√((x2-x1)²+(y2-y1)²)

Substitute

d=√((6+4)²+(3-3)²)

d=√(10)²

d=√100

d=10 units

Hence the perimeter is 5+11.2+10

P=26.2 units

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is a line segment as shown in the image.

We can write the equation as -

(4r - 3) + (r + 7) = 29

4r + r - 3 + 7 = 29

5r + 4 = 29

5r = 25

r = 5

Therefore, the value of [r] will be 5 units.

seth runs every day he jogs 6 miles a day onday through friday every saturday he jogs 8 miles and every sunday 5 miles how many miles in all will seth run in three weeks.

Show your work

Answers

Answer:129

Step-by-step explanation:You have 6 miles a day Monday through Friday,add that up to get 30 and multiply by 3 to get 90. Saturday is 8 so multiply that by 3 to get 24. Sunday is 5 miles so do times 3 to get 15 and add them all up

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The total miles covered in three weeks by Seth is 129 miles.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Seth jogs 6 miles a day from Monday to Friday. Therefore, the total of miles for which Seth runs on weekdays is,

Total miles in weekdays = 6 miles × 5 days

                                         = 30 miles

Also, Seth jogs 8 miles on every Saturday and 5 miles in every Sunday. Therefore, the total miles covered on week off days is,

Total miles on Saturday and Sunday = 8 miles + 5 miles

                                                             = 13 miles

Now, the total miles covered in a week is,

Total miles in a week = 30 miles + 13 miles = 43 miles

Further, the total miles covered in 3 weeks is,

Total miles in three weeks = 3 × 43 miles = 129 miles

Hence, the total miles covered in three weeks by Seth is 129 miles.

What is the nth term rule of the linear sequence below
5, 8, 11, 14, 17, ...
Tn=​

Answers

Answer:

The 12th term is 38

Step-by-step explanation:

Step one:

given the sequence 5, 8, 11, 14, 17, ...

We are required to find the nth term

the formula to find the nth term is given as

Tn = a1 + (n - 1 ) d

a1= the first term

n= the number of terms

d= the common difference

d = 8-5= 3 or 11-8= 3

Step two:

Now say we want to find the 12th term of the sequence n=12

substitute

T12= 5+(12-1)3

T12= 5+(11)3

T12= 5+33

T12= 38

The above formula is used to find the general (or nth) term of an arithmetic sequence.

z=15

Step-by-step explanation:

45 = 3z Because there are three z's, equal to one 45.

45 = 3z

z   = 15

Answer:

B. 45 = 3x

x = 15

Step-by-step explanation:

3 triangles worth "z" value each, is equal to 1 square equivalent to 45 in value. This means that 3z = 45. This means that z = 15, becuase, 3 * 15 = 45.

Use the distributive property to solve this equation:

Answers

X=15

Collect like terms
8x-10x=x-45

C is the circle with the equation x^2 + y^2=1

Answers

Answer:

a) The equation of the tangent to the circle

       x + √3y = 2

b)       [tex]a = \frac{-1}{\sqrt{3} } , b = \frac{2}{\sqrt{3} }[/tex]

Step-by-step explanation:

Step(i):-

Given the equation of the circle x² +y² =1

Tangent equation of the circle x² +y² =a²  is   xx₁ +yy₁ - a² =0

The tangent equation of the given circle

   xx₁ +yy₁ - 1² =0

This equation passes through the point ([tex](\frac{1}{2} , \frac{\sqrt{3} }{2} )[/tex]

       [tex]x(\frac{1}{2} ) +y(\frac{\sqrt{3} }{2} ) =1[/tex]

 ⇒   x + √3y = 2

The equation of the tangent to the circle

       x + √3y = 2

Step(ii):-

Slope - intercept form    y = ax +b

                                   √3y = - x + 2

                                    [tex]y = \frac{-x}{\sqrt{3} } + \frac{2}{\sqrt{3} }[/tex]

where  

           [tex]a = \frac{-1}{\sqrt{3} } and b = \frac{2}{\sqrt{3} }[/tex]
