x+3-5 i think
Step-by-step explanation:
"and" means add so x+3 and subtract 5
Answer:
D
Step-by-step explanation:
literlay just count
13)
Circumference (C) = 2π·r
11π = 2π·r
11/2 = r
******************************
Area (A) = π·r²
= π·(11/2)²
= 121π/4
≈ 94.985 in²
14)
diameter = 2r
42 = 2r
21 = r
*******************
Area (A) = π·r²
= π·(21)²
= 441π
≈ 1384.74 in²
***************************
$280/1384.74 in²
x = $0.20
Answer: about 20 cents per square inch
the explicit formula for aₙ the nth term of the sequence will be:![a_{n}=6\times (\frac{2}{3})^{n-1}\\](https://tex.z-dn.net/?f=a_%7Bn%7D%3D6%5Ctimes%20%28%5Cfrac%7B2%7D%7B3%7D%29%5E%7Bn-1%7D%5C%5C)
Step-by-step explanation:
The explicit formula of geometric sequence is of the form:
![a_{n}=a_{1}r^{n-1}](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7B1%7Dr%5E%7Bn-1%7D)
where a₁ is the first term and r is the common ratio.
We are given:
a₁ = 6
r = 2/3
Putting values in the formula:
![a_{n}=a_{1}r^{r-1}\\a_{n}=6\times (\frac{2}{3})^{n-1}\\](https://tex.z-dn.net/?f=a_%7Bn%7D%3Da_%7B1%7Dr%5E%7Br-1%7D%5C%5Ca_%7Bn%7D%3D6%5Ctimes%20%28%5Cfrac%7B2%7D%7B3%7D%29%5E%7Bn-1%7D%5C%5C)
So, the explicit formula for aₙ the nth term of the sequence will be: ![a_{n}=6\times (\frac{2}{3})^{n-1}\\](https://tex.z-dn.net/?f=a_%7Bn%7D%3D6%5Ctimes%20%28%5Cfrac%7B2%7D%7B3%7D%29%5E%7Bn-1%7D%5C%5C)
