Answer:

(0, 32.1) (1, 29.8)

(29.8 - 32.1)/(1-0)= -2.3/1= -2.3

y - 32.1 = -2.3(x - 0)

y - 32.1 = -2.3x + 0

y = -2.3x + 32.1

Step-by-step explanation:

It is linear

If an=24, which recursive formula could represent the sequence below? ...,24,88, 664, 8408A) An=(An-2)^2 + An-1 ; A1=2B) An= 3An

Rudik [331]

When we substitute $n = 4$ , we get...

$a_{n-3}=a_1\\ \\ a_{n-2}=a_2\\ \\ a_{n-1}=a_3\\ \\ a_n=a_4$

Comparing the given sequence: 24, 88, 664, 8408, we get

$a_{n-3}=a_1=24\\ \\ a_{n-2}=a_2=88\\ \\ a_{n-1}=a_3=664\\ \\ a_n=a_4=8408$

We need to substitute the above values in each option and check which is TRUE.

----

Option A

$a_n=(a_{n-2})^2+a_{n-1}, a_1=2\\ \\ a_n=(88)^2+664=7744+664\\\\a_n=8408 (TRUE)$

Option B

$a_n=3a_{n-1}+16\\ \\ a_n=3(664)+16\\\\a_n=2008 (FALSE)$

Option C

$a_n=(n)a_{n-1}-8\\ \\ a_4=(4)a_3-8=4(664)-8\\\\a_4=2648 (FALSE)$

Option D

$a_n=2a_{n-2}+7a_{n-1}\\ \\ a_n=2(88)+7(664)\\ \\ a_n=4824(FALSE)$

Conclusion:

Option A is the correct answer.

The functions s and t are defined as follows. s(x)=3x-4 t(x)=-5x+3 Find the value of s(t(-1)).

kotegsom [21]

t(x)=-5x+3

t(-1)=-5*(-1)+3=5+3=8

s(x)=3x-4

s(t(-1))=s(8)=3*8-4=24-4=20

answer is 20
