All you do is multiply all the numbers together, and you get V = 168

V = L*W*H
V = 7*8*3
7*8 = 56
56*3 = 168 add the (in) and then i little 3 above the in sign.
168in³

Which expression is equal to the example?

Aloiza [94]

$1-(cosx)^4$ value is $2sin^4-sin^4x$ . Correct option is D) $2sin^4-sin^4x$ .

<u>Step-by-step explanation:</u>

Here we have , expression to evaluate:

$1-(cosx)^4$

⇒ $1-((cosx)^2)^2$

⇒ $1-(1-(sinx)^2)^2$

We know that , $sin^2x = 1-cos^2x$ , putting value in equation $1-(1-(sinx)^2)^2$

⇒ $1-(1+sin^4x-2sin^4)$

⇒ $1-1-sin^4x+2sin^4$

⇒ $-sin^4x+2sin^4$

⇒ $2sin^4-sin^4x$

Therefore , $1-(cosx)^4$ value is $2sin^4-sin^4x$ . Correct option is D) $2sin^4-sin^4x$

The window in Mr. Rodriguez's attic is in two parts, each shaped like a trapezoid and each with identical dimensions.

WINSTONCH [101]

<h2>Answer:</h2>

$\boxed{A=552in^2}$

<h2>Step-by-step explanation:</h2>

The window is shown below, so we have two trapezoids. A trapezoid is a quadrilateral (polygon with exactly 4 sides) where at least one pair of opposite sides are parallel. The area of a trapezoid can be found as:

$A=\frac{(b_{1}+b_{2})h}{2} \\ \\ Where: \\ \\ b_{1} \ and \ b_{2} \ are \ the \ parallel \ sides \ and \ h \ the \ height$

Since there are two trapezoids and each with identical dimensions, we can find the area of the window by finding the area of one trapezoid and multiplying this result by 2:

$A=2 \times \frac{(b_{1}+b_{2})h}{2} \\ \\ A=(b_{1}+b_{2})h \\ \\ where: \\ b_{1}=30in \\ b_{2}=16in \\ h=12in$

Finally:

$A=(16+30)\times 12 \\ \\ \therefore \boxed{A=552in^2}$
