C is the circle with the equation x^2 + y^2=1
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]
i can you help me build the equation
i can graph it though :)

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

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