Answer:

T_1 = 8

T_2 = 14

T_3 = 22

Step-by-step explanation:

Given

T_n = n^2 + 3n + 4

Required:

Find the first 3 terms

To do this, we take the values of n to be 1,2 and 3.

For the first term; n = 1

T_n = n^2 + 3n + 4

T_1 = 1^2 + 3*1 + 4

T_1 = 1+ 3+ 4

T_1 = 8

For the second term; n = 2

T_n = n^2 + 3n + 4

T_2 = 2^2 + 3 * 2 + 4

T_2 = 4 + 6+ 4

T_2 = 14

For the third term; n = 3

T_n = n^2 + 3n + 4

T_3 = 3^2 + 3 * 3 + 4

T_3 = 9 + 9 + 4

T_3 = 22

The interval where the function is nonlinear and decreasing is 0 < x < 4

<h3>How to determine the interval where the function is nonlinear and decreasing?</h3>

The straight lines on the graph are the intervals where the graph is linear

This means that the straight lines on the graph will not be considered

Considering the curve, the graph decrease from x = 0 to x = 4

This can be rewritten as:

0 < x < 4

Hence, the interval where the function is nonlinear and decreasing is 0 < x < 4

Answer:

x = 71/5  (as an improper fraction)

x = 14 1/5 (as a proper fraction

x = 14.2 (as a decimal)

Step-by-step explanation:

It's a rectangle so the diagonals are equal

7x - 9 = 2x + 62

Subtract 2x from both sides

5x - 9 = 62

Add 9 to both sides

5x = 71

Divide both sides by 5

x = 71/5  (as an improper fraction)

x = 14 1/5 (as a proper fraction

x = 14.2 (as a decimal)
