The area (A) of the major sector is

A = area of circle × fraction of circle

   = πr² × \frac{255}{360}

   = π × 13.4² × \frac{255}{360}

Position to term rule of 2, 6, 10, 14, 18<br><br> multiply by _____ and subtract by _____
andreyandreev [35.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the sequence

2, 6, 10, 14, 18

An arithmetic sequence has a constant difference and is defined as

\:a_n=a_1+\left(n-1\right)d

compute the differences of all the adjacent terms

6-2=4,\:\quad \:10-6=4,\:\quad \:14-10=4,\:\quad \:18-14=4

The difference between all the adjacent terms is the same.

Thus,

d=4

and

a_1=2

Therefore, the nth term is computed by:

a_n=4\left(n-1\right)+2

a_n=4n-2

Thus, position to term rule of 2, 6, 10, 14, 18  multiply by __4___ and subtract by __2__.

Simplify: -10 - 90x + 6x - 60
antoniya [11.8K]

<u><em>Answer:</em></u>

- 84x - 70

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

We want to combine like terms:

-10 - 90x + 6x - 60

We can see (-10) and (-60) are both regular constants so:

- 10 - 60 = - 70

Then (-90x) and (+ 6x):

6x - 90x = - 84x

- 84x - 70

hammer [34]

Answer:

7. is G

8. f(4)=-120

Step-by-step explanation:

7. les do f(0)=4 since its the easiest

F. f(0)=0.4(0+5)(0-2)

    0.4*-2*5=-4                NOT IT. the ans. is +

G. f(0)=-0.4(0+5)(0-2)

    -0.4*-2*5=4               YESSSSSS

H. f(0)=-0.4(0-5)(0+2)

     -0.4*2*-5=4              YESSSSSS

J. f(0)=0.4(0-5)(0+2)

     0.4*2*-5=-4              NOT ITTTT

so G n H

 Put both equation=0

G. 0=-0.4(x+5)(x-2)

    x=-5,2     YASSSS this is the ans.
