Here are the areas of the 12 rectangular surfaces that make up the surface area of the podium:

7.5 x 1.5 = 11.25 square feet (Bottom)

1.5 x 1.5 x 2 = 4.5 square feet (Right/Left Bottom Sides)

2.5 x 1.5 x 2 = 7.5 square feet (Right/Left Flat)

1.5 x 1.5 x 2 = 4.5 square feet (Right/Left Top Sides)

2.5 x 1.5 x 2 = 7.5 square feet (Top Front/Back)

2.5 x 1.5 = 3.75 square feet (Top)

7.5 x 1.5 x 2 = 22.5 (Bottom Front and Back)

The area of all these surfaces is 61.5 square feet.

How much fibre does the NHS recommend adults take in as a daily dose?

iVinArrow [24]

Answer:

The answer is D: 30 g.

Step-by-step explanation: I googled the answer to this question and it said that NHS reccomends that adults take around 30 g of fibre as a daily dose. If you take less, you may not get enough, but if you take more, you would possibly overdose. So, the answer is D: 30g.

How do i prove 2sec^2x-2sec^2xsin^2-sin^2x-cos^2x=1

kramer

$2\sec^2x-2\sec^2x\sin^2x-\sin^2x-\cos^2x=2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)$

Since $\sin^2x+\cos^2x=1$ , you have

$2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)=2\sec^2x\cos^2x-1$

and since $\sec x=\dfrac1{\cos x}$ , you end up with $2-1=1$ .
