Answer:

92 sq. inches

Step-by-step explanation:

Total paper required = total surface area

Surface area of a cuboid = 2[(l×b) + (l×h) + (b×h)],

Where 'l' is the length, 'b' is the breadth and 'h' is the height

For the box, total surface area = 2[(8×3) + (3×2) + (8×2)]

=2[24 + 6 + 16]

=2[46]

= 92 sq. inches

Answer:

Step-by-step explanation:

The box is in the shape of a cuboid.

The top and bottom of the box is 8in by 3in. The area of the top and the bottom of the box would be

2 × 8 × 3 = 48 square inches.

The sides are both 3in by 2in. The area of the two opposite sides of the box would be

2 × 3 × 2 = 12 square inches.

The front and back are 8in by 2in. The area of the front and back would be

2 × 8 × 2 = 32 square inches.

The amount of wrapping paper that Chloe needs to wrap the present would be

48 + 12 + 32 = 92 square inches

prove that sin theta cos theta = cot theta is not a trigonometric identity by producing a counterexample
Zolol [24]

Answer:

To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.

Begin with the right hand side:

R.H.S = cot θ = \frac{cos \ \theta}{sin \ \theta}

L.H.S = sin θ cos θ

so, sin θ cos θ ≠ \frac{cos \ \theta}{sin \ \theta}

So, the equation is not a trigonometric identity.

=========================================================

<u>Anther solution:</u>

To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.

Assume θ with a value and substitute with it.

Let θ = 45°

So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2

R.H.S = cot θ = cot 45 = 1

So, L.H.S ≠ R.H.S

So, sin θ cos θ = cot θ is not a trigonometric identity.

Which of the following is the conjugate of 10 – 3i?
ipn [44]

we know that

The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign

so

In this problem we have

10-3i

the conjugate is equal to--------> 10+3i

therefore

<u>the answer is the option</u>

10+3i
