Answer:
7/12
Step-by-step explanation:
The nth term Tₙ = n(n-4) /n+3.
The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4
The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3
So, the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3
= (-9 + 16)/12
= 7/12
Answer: a=5+√5
b=5-√5
Step-by-step explanation:
a=?
b=?
P=20
A=20
P=a*b=20
A=a+b=20
------------------
ab=20
a+b=10
--------
a=10-b
(10-b)b=20
-b²+10b-20=0
b=-10±√100-80/-2
b=-10±√20/-2
b=-10±2√5/-2
b=-10-2√5/-2=5+√55
b=5-√5
a+b=10
a+5-√5=10
a=5+√5
a+5+√5=10
a=5-√5

Answer:
i believe the answer is A
Step-by-step explanation:
Hi there! The answer is ( - 7, 5)
The standard form of the equation of a circle is the following:
In this equation r represents the radius of the circle and the point (a, b) is its centre.
Therefore, the centre of the circle
is the point ( - 7, 5).
