Answer:

the second option is correct

Step-by-step explanation:

A(n)=-2.5ⁿ-¹

for first term

let n=1

A(1)=-2.5¹-¹

=-2.5^(0)

=-2(1)=-2

for fourth term

let n=4

A(4)=-2.5⁴-¹

=-2.5³

=-2.125

=-250

for eighth term

let n=8

A(8)=-2.5^(8-1)

=-2.5^7

=-2.78125

=-156,250

Answer:

<1 = 33 degrees

<2 = 33 degrees

<3 = 114 degrees

Step-by-step explanation:

<1 and <2 = x

<3 = 3x+15

<1 + <2 + <3 = 180 degree

x + x + 3x + 15 = 180

5x = 180 - 15

x = 165/5

x = 33

<3 = 3(33)+15

= 114 degrees

The sector area and the arc length are 34.92 square inches and 13.97 inches, respectively

<h3>How to find a sector area, and arc length?</h3>

For a sector that has a central angle of θ, and a radius of r;

The sector area, and the arc length are:

$A = \frac{\theta}{360} * \pi r^2$ --- sector area

$L = \frac{\theta}{360} * 2\pi r$ ---- arc length

<h3>How to find the given sector area, and arc length?</h3>

Here, the given parameters are:

Central angle, θ = 160

Radius, r = 5 inches

The sector area is

$A = \frac{\theta}{360} * \pi r^2$

So, we have:

$A = \frac{160}{360} * \frac{22}{7} * 5^2$

Evaluate

A = 34.92

The arc length is:

$L = \frac{\theta}{360} * 2\pi r$

So, we have:

$L = \frac{160}{360} * 2 * \frac{22}{7} * 5$

L = 13.97

Hence, the sector area and the arc length are 34.92 square inches and 13.97 inches, respectively

Direct variation is when $\dfrac{y}{x}$ is the same for each coordinate.

Indirect variation is when x · y is the same for each coordinate.

11. Answer: Direct Variation

<u>Step-by-step explanation:</u>

$\begin {array}{c||c|c|c|c|c}x&12&18&23&29&34\\y&132&198&253&319&374\\\\\dfrac{y}{x}&\dfrac{132}{12}=11&\dfrac{198}{18}=11&\dfrac{253}{23}=11&\dfrac{319}{29}=11&\dfrac{374}{34}=11\\\end{array} \\\\\\\text{The coordinates x and y show a direct variation.}$

12. Answer: Indirect Variation

<u>Step-by-step explanation:</u>

$\begin {array}{c||c|c|c|c|c}x&4&6&8&8.4&12\\y&21&14&10.5&10&7\\x\cdot y&4\cdot 21=84&6\cdot 14=84&8\cdot 10.5=84&8.4\cdot 10=84&12\cdot 7=84\\\end{array} \\\\\\\text{The coordinates x and y show an indirect variation.}$
