Answer:

  • 9/4

Step-by-step explanation:

<u>The perfect square identity is:</u>

  • (a + b)² = a² + 2ab + b²

<u>Apply to the given equation to complete the square:</u>

  • x² + 3x = 6
  • x² + 2*x*(3/2) + (3/2² = 6 + (3/2)²
  • (x + 3/2)² = 6 + 9/4
  • (x + 3/2)² = 8 1/4

Required number is 9/4

Find the 8th term in the sequence with this explicit formula:<br> c(n) = -6 + 5(n - 1)
QveST [7]

We are given this explicit formula :

c(n) = -6 + 5(n - 1)

In order to find eighth term let us plug n as 8 in this formula:

c(8) = -6 + 5(8 - 1)

subtracting 8-1 first using pemdas rule

c(8) = -6 + 5(7)

multiplying 5 and 7

c(8) = -6 + 35

subtracting 35-6

c(8) = 29

So eighth term is 29.

I was told that the answer to this is -7 but I don't understand how to get there.
Amiraneli [1.4K]

Answer:

The answer to your question is: - 7

Step-by-step explanation:

                                            3125 = (- 1  - 18t) ⁵/³

                                            (3125)³ = ( -1 - 18t)⁵

                                            (3125)³/⁵ = - 1 - 18t

                                            125 = - 1 - 18t

                                            125 + 1 = - 18t

                                            126 = - 18t

                                            t = 126 / -18

                                            t = -7

3125³ = 3.0518 x 10¹⁰

\sqrt[5]{3.0518 x 10¹⁰} = 125

Simplify (5x^2 -3x+3) - (x^2+2x-1).
Natali [406]
Eliminate parenthesis by using the distribution property

= 5x² -3x +3 - x² - 2x +1

Group similar terms

= (5-1)*x² + (-3 -2)*x + (3+1)

Then sum everything:

= 4x² -5x +4
