What are the next 4 terms to this sequence<br><br>2, 6, -4, 10, -14,

Kay [80]

Answer:

24, -38, 62, -100

Step-by-step explanation:

The recursive formula is a_n = a_(n-2) - a_(n-1)

so. we try this 4 times after the -14 term

a_3 = -4 = 2 - 6 = a_1 - a_2

...

a_6 = a_4 - a_5 = 10 - (-14) = 24

a_7 = a_5 - a_6 = -14 - (24) = -38

a_8 = a_6 - a_7 = 24 - (-38) = 62

a_9 = a_7 - a_8 = -38 - 62 = -100

a_10 = a_8 - a_9 = 62 - (-100) = 162

The total revenue for dante's villas is given as the function r(x)=300x−0.2x2, where x is the number of rooms filled. What numbe

FinnZ [79.3K]

Solution:- Given that the total revenue function

$r(x)=300x-0.2x^2$ ,where x is the number of rooms filled

Now, differentiating the function w.r.t. x,we get

$r'(x)=300-0.4x$

To find critical points ,Put $r'(x)=0$

$\Rightarrow300-0.4x=0\\\Rightarrow0.4x=300\\\Rightarrow x=750\\\text{Now}\\r"(x)=-0.4$

Crank

Answer:measurement of angle B is

$70 \: \: degrees$

<h3>Answer C is correct</h3>

Step-by-step explanation:

$6x - 2 + 5x + 18 + 2x + 8 = 180 \\ 13x + 24 = 180 \\ 13x = 180 - 24 \\ 13x = 156 \\ \frac{13x}{13} = \frac{156}{13} \\ x = 12 \: \: degrees$
