829 rounded to the nearest tenth is 830

If the 9 would be a 4 or lower, then it would be 820, but in this case, it's a number larger than 5, so it would be 830.

What is the area of the shaded region?

-BARSIC- [3]

Answer:

25π - 24 cm²

Step-by-step explanation:

area of circle:

A = πr²

A = π(5²)

A = 25π

Area of triangle:

base = 6

height = 5 - 1 = 4

(1/2)(6 * 4) = 12

there are 2 triangles so unshaded area is 24 cm²

Area of shaded region = 25π - 24 cm²

9,-81, 729,-6561...<br> What is the common ratio?<br> Help which is the correct answer?

GrogVix [38]

Answer:

$r = -9$

Step-by-step explanation:

Given

$Sequence: 9,-81, 729,-6561...$

Required

Determine the common ratio

The common ratio r is calculated using:

$r = \frac{T_n}{T_{n-1}}$

Let $n = 2$

So, we have:

$r = \frac{T_2}{T_{2-1}}$

$r = \frac{T_2}{T_1}$

From the sequence:

$T_2 = -81$

$T_1=9$

So, the equation becomes

$r = \frac{-81}{9}$

$r = -9$
