Am I correct? (Perfect Square Form)

natka813 [3]

Answer:

$(x -3 )^2 = 10$

Step-by-step explanation:

Given

$x^2 - 6x - 1 = 0$

Required: Express as a perfect square

$x^2 - 6x - 1 = 0$

Add 10 to both sides

$x^2 - 6x - 1 +10= 0+10$

$x^2 - 6x +9= 10$

Expand

$x^2 - 3x - 3x+9= 10$

Factorize:

$x(x - 3) - 3(x - 3)= 10$

Factorize:

$(x -3 )(x - 3) = 10$

$(x -3 )^2 = 10$

URGENT! Please help me with this question!!!!!

Artist 52 [7]

Answer:

$\boxed{GJ = 76 \ degrees}$

Step-by-step explanation:

According to Angles of intersecting chords theorem:

∠GAJ = $\frac{1}{2} (BD+GJ)$

Where ∠GAJ = 50 , BD = 24 and GJ = ?

50 = $\frac{1}{2} (24+GJ)$

Multiplying both sides by 2

100 = 24 + GJ

GJ = 100-24

GJ = 76 degrees

3. A submarine dives at an

Vesna [10]

Answer:

The height of deepness of submarine is 424.1 feet

Step-by-step explanation:

Given as :

The angle at which submarine drives of the surface of water = Ф = 13°

The speed at which submarine travel = s = 760 feet per minute

Let The height of deepness of submarine = h feet

The time taken to reach that deepness = t = 5 minutes

<u>According to question</u>

The height of deepness of submarine = $\dfrac{\textrm speed}{\textrm time}$

i.e h × cos(90 - Ф) = $\dfrac{s}{t}$

Or, h × Sin(Ф) = $\dfrac{\textrm 760 feet per min}{8 min}$

Or, h × Sin(13°) = 95 feet

Or, h × 0.224 = 95 feet

∴ h = $\dfrac{95}{0.224}$

i.e h = 424.10 feet

So, The height of deepness of submarine = h = 424.10 feet

Hence, The height of deepness of submarine is 424.1 feet Answer
