A rectangular box has the dimensions shown in the diagram. The volume of the box is given by the function V(x) = x3 – 4x, where
marta [7]

Answer:

Height =3

Step-by-step explanation:

Given

Length = x + 2

Width = x - 2

Height = x

Volume = 15

Required

Find the height

The volume is calculated as thus:

Volume = Length * Width * Height

This gives

15 = (x + 2) * (x - 2) * x

Apply difference of two squares

15 =(x^2 - 4 ) * x

15 = x^3 - 4x

Subtract 15 from both sides

x^3 - 4x - 15 = 0

Using a calculator to factorize, we have:

(x-3)(x^2+3x+5) = 0

Split

x - 3 = 0 or x^2 + 3x + 5 = 0

x = 3 or  x^2 + 3x + 5 = 0

x has complex roots for x^2 + 3x + 5 = 0

Hence:

x = 3

Recall that:

Height = x

Height =3

Please what is 33×33+33-33÷0​
DochEvi [55]

Answer:

33×33+33-33÷0=infinity

33×33=1089

33-33=0

Taking L.H.S

=33×33+(33-33)÷0

=1089+0÷0

=1089÷0

=infinity

L.H.S=R.H.S

Find the area of △LKJ.
nirvana33 [79]

Answer:

A=600\: u^{2}

<u>The correct answer is letter c.</u>

Step-by-step explanation:

The area equation of a triangle is given by:

A=\frac{bh}{2}  (1)

Where:

b is the base

h is the height

Let's find first the angle MJK (α), using the tangent definition.

tan(\alpha)=\frac{24}{32}

\alpha=tan^{-1}(\frac{24}{32})

\alpha=36.9^{\circ}

Now, if α = 37° then β (angle JLK) must be:

37^{\circ} + \beta + 90^{\circ}=180^{\circ}

\beta=53^{\circ}

Now, we can find the distance ML using again the tangent definition:

tan(\beta)=\frac{24}{ML}

ML=\frac{24}{tan(53)}

ML=18

The base of the triangle LKJ will be:

b=32+ML=32+18=50

Therefore, using equation (1) the area of △LKJ will be:

A=\frac{50*24}{2}

A=600\: u^{2}

The correct answer is c.

I hope it helps you!
