Answer: There are 31 chairs that can be upholstered with 4 bolts of fabric.

Step-by-step explanation:

Since we have given that

1\ m^2=10.7639\ ft^2

Volume = 273.5 m²

Number of bolts of fabric = 4

So, Total volume would be

273.5\times 4\\\\=1094\ ft^2

Since 34.7 sq. ft of fabric is needed to upholster one chair.

So, the number of chairs that can be upholstered with 4 bolts of fabric would be

\dfrac{1094}{34.7}\\\\=31.53\\\\\approx 31

Hence, there are 31 chairs that can be upholstered with 4 bolts of fabric.

Answer:

13.5

Step-by-step explanation:

Similar = alike but not the same

A lot of times in geometry it would mean that they have the same shape, just different size, so first find the ratio:

6/12 = 1/2

27 * 1/2 = 27/2 = 13.5

Evaluate s(t)=∫t−[infinity]||r′(u)||du for the bernoulli spiral r(t)=⟨etcos(8t),etsin(8t)⟩. It is convenient to take −[infinity]
sveta [45]

\vec r(t)=\langle e^t\cos8t,e^t\sin8t\rangle

\|\vec r'(t)\|=\sqrt{(e^t(\cos8t-8\sin8t))^2+(e^t(\sin8t+8\cos8t))^2}=e^t\sqrt{(\cos8t-8\sin8t)^2+(\sin8t+8\cos8t)^2}

\implies\|\vec r'(t)\|=e^t\sqrt{65}

Then

s(t)=\displaystyle\sqrt{65}\int_{-\infty}^te^u\,\mathrm du=\sqrt{65}e^t
