What is the equation of the circle with center (-6,7) that passes through the point (4,-2). A. (x+6)^2+(y-7)^2=181 B. (x-6)^2+(y

pychu [463]

The equation of a cricle passing through (h,h) and with radius r is
$(x-h)^2+(y-k)^2=r^2$
so

cente ris (-6,7) and passing through (4,-2)
$(x-(-6))^2+(y-7)^2=r^2$
$(x+6)^2+(y-7)^2=r^2$
subsitute (4,-2) to find r^2

$(4+6)^2+(-2-7)^2=r^2$
$(10)^2+(-9)^2=r^2$
$100+81=r^2$
$181=r^2$

so it is

$(x+6)^2+(y-7)^2=181$
A is the answer

Which equation should be used to calculate the 43rd partial sum for the arithmetic sequence.

MariettaO [177]

Answer: First Option : Sₙ= n/2(a₁ + aₙ)

Step-by-step explanation:

The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.

It is calculated using the formula:

Sₙ= n/2(a₁ + aₙ)

Where :

a₁ = First term

aₙ = last term

n = number of terms
