Step-by-step explanation:
A line contains two infinite arrows, no endpoints.
<h3>A sequence is defined by the recursive function then f(1) is 81</h3>
<em><u>Solution:</u></em>
Given that,
A sequence is defined by the recursive function:
------ eqn 1
Given that,

<em><u>Substitute n = 2 in eqn </u></em><em><u>1</u></em>

<em><u>Substitute n = 1 in eqn 1</u></em>

Thus f(1) is 81
If these triangles are congruent, then side RS is congruent to side TV and that means that y = 4 - x. If y = 4-x, we can sub that into the next equation where side RV = side ST and 1 = 4x - y. If y = 4-x, we sub in accordingly to get 1 =4x - (4 - x). That simplifies to 1 = 4x - 4 + x which is, combining like terms, 5 = 5x. That means that x = 1. If x = 1, and y = 4 - x, then y = 4 - 1 and y = 3. There you go!
Answer:31.69
Step-by-step explanation:
31.69
Answer:
Step-by-step explanation:
(13)2−(2x+7)=0
19x2−2x−7=0
9(19x2−2x−7)=9(0)
x2−18x−63=0
(x−21)(x+3)=0
Therefore, the value of x are
x - 21 = 0 and x + 3 = 0
x = 21 x = -3
