Consider that an = 4n-1 represents a sequence. what is the tenth term?n-1 is a exponent

Katen [24]

Geometric sequence since exponent
$a_n=a_1r^{n-1}$
a1=firs term
r=common ratio
n=which term

no first term given, or is there?
4^(n-1), first term is 1, common ratio is 4

just plug in 10 for n
$a_{10}=(1)4^{10-1}$
$a_{10}=4^{9}$
$a_{10}=4^{9}$
$a_{10}=262144$
tenth term is 262144

A circle is centered at the point (-7,-1) and passed through (8,7) what is the radius of the circle, what is the Y to the coordi

Kryger [21]

The formula of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center. Since (-7,-1) is the center, we have (x+7)^2+(y+1)^2=r^2. To find the radius, we need to find the distance between (-7,-1) and (8,7). Using the distance formula, we get the radius is 17 (make a right triangle with height 8 and base 15). Now, we have (x+7)^2+(y+1)^2=289. Plug in -15 for x and we have (y+1)^2+64=289. (y+1)^2=225. y+1=+-15. y=14, -16. So the Y is 14 and -16.
