If the height of a right triangular prism is 1 5/6 inches. The surface area of the solid formed is: 598.33 in².

<h3>Surface area</h3>

First step

Right triangular prism=1 5/6 inches= 11/6 inches

Height of the base=8 2/3 inches = 26/3 inches

Second step

Surface area = 5(10× 10) + (0.5÷ 10 × 26/3) + 3(10× 11/6)

Surface area = 5(100) +43.33+ 3(18.33)

Surface area = 500) +43.33 + 55

Surface area = 598.33 in²

Therefore the surface area of the solid formed is about 598.33 in²

A case a 24 pairs of same king of sports shoes cost a little more than $800. Explain whether $28 per pair is a good estimate of

bixtya [17]

Total number of pairs = 24 pairs.

Total cost of 24 pairs = $800 approximately.

Cost of each pair = $\frac{Total \ cost \ of\ 24 \ pairs }{Number \ of \ pairs }$

Plugging values in the above formula, we get

Cost of each pair = $\frac{800}{24}$

If we divide 800 by 24, we get 33.33 approximately.

But in the given problem, estimated cost is given $28 per pair.

If we subtract 33.33-28, we get $5.33.

So, the estimated cost is $5.33 each pair less than the actual cost of each pair.

Therefore, $28 per pair is not a good estimate of the price.

a. Recall the double angle identities:

$\sin^2x=\dfrac{1-\cos2x}2$

$\cos^2x=\dfrac{1+\cos2x}2$

Then

$\sin^2x\cos^2x=\dfrac{(1-\cos2x)(1+\cos2x)}4=\dfrac{1-\cos^22x}4$

Applying the identity again, we have

$\sin^2x\cos^2x=\dfrac{1-\frac{1+\cos4x}2}4=\dfrac{2-(1+\cos4x)}8=\dfrac{1-\cos4x}8$

as required.

b. Using the result from part (a),

$\sin^2x\cos^2x=\dfrac{1-\cos4x}8=\dfrac{2-\sqrt2}{16}$

$\implies\cos4x=\dfrac1{\sqrt2}$

$\implies4x=\dfrac\pi4+2n\pi\text{ or }4x=-\dfrac\pi4+2n\pi$

(where $n$ is any integer)

$\implies\boxed{x=\pm\dfrac\pi{16}+\dfrac{n\pi}2}$
