A(n) = a₁.(r)ⁿ⁻¹, where a₁ = 1st term, r= common ratio and n, the rank

In the formula given a₁ = 5, r = 3/2 and n = 6 (we have to find the 6th term value).

a₆ = 5.(3/2)⁶⁻¹ = 5.(3/2)⁵ = 1215/32 (answer C)

Q3.) Write the standard form of the equation of the circle with the given center and radius.
vlada-n [284]
The center has coordinates h = -2, k = 5.  The radius is sqrt(6).  The equation for a circle is as follows: (x-h)^2+(y-k)^2=r^2.  Filling in using our given info we have (x-(-2))^2+(y-5)^2=( \sqrt{6})^2.  Simplifying that down we have an equation of (x+2)^2+(y-5)^2=6.  There you go!

a_sh-v [17]

Answer:

  • 9/160
  • 9/160

Step-by-step explanation:

Divide each number in the ratio by their greatest common divisor.

  4500 : 80000 = (4500/500) : (80000/500) = 9 : 160

  8100 : 144000 = (8100/900) : (144000/900) = 9 : 160

The perimeter of a 5-sided figure is 45.56 meters. Two of the sides have the same length. The sum of the other three side length
balandron [24]
10.68 each for the 2 same length sides. The total of the 5 sides is 45.56 less the 3 sides which total 24.2 leaves 21.36 remaining for the 2 equal length sides. So divide 21.36 by 2 = 10.68
(45.56 - 24.2)/2 = 10.68
