Show that the equation x^3-3x^2+3=0 has a solution between x=2 and x=3

Mathematics

The equation has 3 solutions (determined by the degree of polynomial and non-extreme case).

If you use cubic equation to try and solve the equality you get

x_1\approx-0.88 \\ x_2\approx1.35 \\ x_3\approx2.53

Clearly third one is in (2,3) so the statement that one solution is between 2 and 3 is true.

Hope this helps.

Find the area of triangle ABC. Give your answer to 1 decimal place. Sine rule.
laiz [17]

Answer:

<h2> 31.7 cm^2</h2>

Solution,

In ∆ ABC

< A + <B + < C = 180°

or, 72 + 59 + <C = 180°

or, 131 + <C = 180°

or, <C = 180 - 131

< C = 49

Area of ∆ABC = 1/2 ab sin C

= 1/2 * 12 * 7 * sin 49

= 42 * sin 49

= 31.7 ( approximately)

Hope this helps...

Good luck on your assignment...

Yuliya22 [10]
14 x² + 6 x - 7 x - 3 =
= ( 14 x² - 7 x ) + ( 6 x - 3 ) =
= 7 x ( 2 x - 1 ) + 3 ( 2 x - 1 ) =
= ( 2 x - 1 ) ( 7 x + 3 )
Answer:
1.  GCF of the group ( 6 x - 3 ) is 3.
2.  The common binomial factor is 2 x - 1.
3.  The factored expression is:  ( 2 x - 1 ) ( 7 x + 3 ).
