$T_n = a_1 + d(n-1)$

If a = 4 and d = 3,

$T_n = 4+ 3(n-1)$

$T_n = 4+ 3n-3$

$T_n = 3n + 1$

Which best describes the range of the function f(x)=2/3(6)^x after it's been reflected over the x-axis

Norma-Jean [14]

The function $6^x$ is an exponential with base greater than 1. So, its range is $(0,\infty)$ , with 0 being the horizontal asymptote as $x \to -\infty$ .

If you multiply the function by $\frac{2}{3}$ , the range remains the same.

If you reflect it over the x-axis, you're changing the sign of the function. So, the new range is

$(-\infty,0)$

Answer:

-569

Step-by-step explanation:

$20 - 30 + (40)(11) - 12 + 13 - 1000$
$-10 + (40)(11) - 12 + 13 -1000$
$-10 + 440 - 12 + 13 -1000$
$430 - 12 + 13 - 1000$
$418 + 13 - 1000$
$431 - 1000$

m_a_m_a [10]

Answer: $282.85\ cm^2$

Step-by-step explanation:

Given

Radius of cylinder $r=5\ cm$

The height of the cylinder is $h=9\ cm$

The surface area of a cylinder is $2\pi rh$

If only the outer is considered then, the area required is

$\Rightarrow A=2\times \dfrac{22}{7}\times 5\times 9\\\\\Rightarrow A=282.85\ cm^2$
