Answer:
Explanation:
In the given geometric sequence:
We see that:
• The first term, c1 = 4
Also:
• The common ratio, r= -1/3
The explicit formula for a geometric function is obtained using the formula:
Substituting a (the first term, c(1)) and r, we have the explicit formula below:

Answer:
The value of cos 0 = - 2 sqrt(85) / 85 = - 0.216930458
Step-by-step explanation:
cos 0 = ?
Point on the terminal side of 0 : (-2,9)=(x,y)→x=-2, y=9
cos 0 = x/r
r=sqrt(x^2+y^2)
Replacing the known values:
r=sqrt( (-2)^2+(9)^2)
r=sqrt(4+81)
r=sqrt(85)
cos 0 = x/r
cos 0 = -2 / sqrt(85) = -2/9.219544457 = -0.216930458
Rationalizing:
cos 0 = -[2 / sqrt(85)] [sqrt(85) / sqrt(85)]
cos 0 = - 2 sqrt(85) / [sqrt(85)]^2
cos 0 = - 2 sqrt(85) / 85
Answer:100/9
Step-by-step explanation:
3 1/3 x 3 1/3
(3x3+1)/3 x (3x3+1)/3
10/3 x 10/3=100/9
There are 5 yellow roses in each of Michelle's vases.
<u>Colise</u>
2 vases x 10 red roses = 20 total red roses
2 vases x 5 yellow roses = 10 total yellow roses
20 red roses + 10 yellow roses = 30 total roses
<u>Michelle</u>
30 total roses / 6 red roses in each vase = 5 yellow roses in each vase
