Show that the equation x^3+4x=6 has a solution between 1.1 and 1.2
SVEN [57.7K]

Answer:

see explanation

Step-by-step explanation:

If there is a solution between x = 1.1 and x = 1.2 then there will be a change in sign when the equation is evaluated at the points, indicating the graph has crossed the x- axis, where the solution lies.

Given

x³ + 4x = 6 ( subtract 6 from both sides )

x³ + 4x - 6 = 0 ← in standard form

Evaluating for x = 1.1

(1.1)³ + 4(1.1) - 6

= 1.331 + 4.4 - 6 = - 0.269 ← < 0

Evaluating for x = 1.2

(1.2)³ + 4(1.2) - 6

= 1.728 + 4.8 - 6 = 0.528 ← > 0

Since there is a change in sign the graph has crossed the x-axis from below /   indicating a solution between x = 1.1 and x = 1.2

sesenic [268]
The answer is:  " 312.5 " . 
_________________________________________________
<u>Note</u>:  In the pattern given, each number is multipled by "5" to get to the number consecutive number.
__________________________________________________
The pattern given is:
__________________________________________________
  " 0.5, 2.5, 12.5, 62.5, ____, ....."  ;

Note:  The first number in the pattern given is:  "0.5" .

"0.5 * 5 = 2.5" ; and "2.5" is the second number in the pattern.

"2.5 * 5 = 12.5" ; and "12.5" is the third number in the pattern.

"12.5 * 5 = 62.5" ; and "62.5" is the fourth number (and final number SHOWN in                                                                                       the pattern).

To find the next number, we multiply "62.5" by "5" ;  to get:  "312.5" .

What is the largest number ??
stellarik [79]

Answer:

83

Step-by-step explanation:

x = 1st number

x+2 is the next consecutive odd number

x+ x+2 = 164

Combine like terms

2x+2 = 164

Subtract 2 from each side

2x= 162

Divide by 2

2x/2 =162/2

x = 81

x+2 = 83

The largest number is 83
