Find the first four terms of the sequence using the recursive formula.

frozen [14]

Answer:

- 3, - 11, - 35, - 107

Step-by-step explanation:

Using the recursive formula with f(1) = - 3 , then

f(2) = - 2 + 3f(1) = - 2 + 3(- 3) = - 2 - 9 = - 11

f(3) = - 2 + 3f(2) = - 2 + 3(- 11) = - 2 - 33 = - 35

f(4) = - 2 + 3f(3) = - 2 + 3(- 35) = - 2 - 105 = - 107

Thus the first four terms are

- 3, - 11, - 35, - 107

Choose the equation that satisfies the data in the table.

Answer:

B. y = $\frac{2}{15} X + 2$

Step-by-step explanation:

I. Given x = 15 and y = 4

4 = $\frac{2}{15}(15) + 2$

4 = 2+2

4 = 4 true

II. Give x = 0 and y = 2

2 = $\frac{2}{15}(0) + 2$

2 = 0 + 2

2 = 2 true

III. Given x = -15 and y = 0

0 = $\frac{2}{15}(-15) + 2$

0 = -2 + 2

0 = 0 true

Good luck.

Answer:

Factorized

$=(2x-8)(x-3)$

Roots : 4 , 3

Step-by-step explanation:

If it is to factorize :

$2x^2 - 14x + 24 = 2x^2 -6x-8x +24$

$=2x(x-3)-8(x-3)\\=(2x-8)(x-3)$

If it is to solve for x :

$2x^2 -1 4x + 24 = 0\\(2x-8)(x-3)=0\\2x - 8 = 0 \ , \ x - 3 = 0\\2x = 8 \ , \ x = 3\\x = 4 , 3$
