Tan(29°) = opposite/adjacent = AC/CB ⇒
CB = AC/tan(29°) = 20/0.5543 ≈ 36.08

sin(29°) = opposite/hypotenuse = AC/AB ⇒
AB = AC/sin(29°) = 20/0.4848 ≈ 41.25

∠A = 180 - ∠B - ∠С = 180 - 29 - 90 = 61°

Find the exact volume of the cylinder.

netineya [11]

Step-by-step explanation:

The volume of a cylinder can be found with the equation

$\pi{r}^{2}h$

So, plug in the values. The diameter of the circle is 10m, which means that the radius is 5m. The height of the cylinder is 13m.

V = π (5)^2 (13)

V = 325π m^3

Answer:

D. 325π m^3

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for t

Marizza181 [45]

Answer:

$a_n = -2 + n$ is an expression which describe the given sequence

Step-by-step explanation:

Arithmetic sequence states that a sequence where the difference between each successive pair of terms is the same.

The general rule for the arithmetic sequence is given by;

$a_n =a_1+(n-1)d$ ......[1]

where

$a_1$ represents the first term

d represents the common difference

and n is the number of terms;

Given sequence: -1 , 0 , 1 , 2 , .....

This is an arithmetic sequence with common difference

Since,

0-(-1) = 1

1-0 =1

2-1 = 1 ....

Here, $a_1 = -1$

Substitute the value of $a_1 = -1$ , d =1 in [1] we get

$a_n = -1 +(n-1)(1)$

$a_n = -1 + n -1 = -2 +n$

Therefore,an expression which describe the given sequence is, $a_n = -2 + n$

What is the quotient when 2x^3-1 is divided by x - 1?

andrey2020 [161]

Answer:

Step-by-step explanation:

Use synthetic division:

The coefficients of 2x^3 - 1 are {2, 0, 0, -1}. Setting up synthetic division, we get:

1 / 2 0 0 -1

2 2 2

---------------------------

2 2 2 1

Note that the remainder is 1. The same result would be obtained through long division.

The quotient is 2x^2 + 2x + 2 with a remainder of 1.
