Answer:

Step-by-step explanation:

A printer takes two and one half seconds to print a flyer it took 75 seconds to print a batch of flyers without stopping how many flyers were printed with a multiplication and division equation and solve?

From the above question:

2 1/2 seconds = 1 flyer

75 seconds = x flyer

Cross Multiply

2 1/2 seconds × x flyer = 75 seconds × 1 flyer

Mashutka [201]

Answer:

\sqrt\frac{387}{20}

Step-by-step explanation:

Arc Length =\int\limits^a_b {\sqrt{1+(\frac{dy}{dx})^2 } } \, dx

y=\dfrac{3}{5}x^{\frac{5}{3}}-  \dfrac{3}{4}x^{\frac{1}{3}}+6

\frac{dy}{dx} =x^{\frac{2}{3}}-\dfrac{1}{4}x^{-\frac{2}{3}}

1+(\frac{dy}{dx})^2 }=1+(x^{\frac{2}{3}}-\dfrac{1}{4}x^{-\frac{2}{3}})^2\\=1+(x^{\frac{4}{3}}-\dfrac{1}{2}+ \dfrac{1}{16}x^{-\frac{4}{3}})

=\dfrac{1}{2}+x^{\frac{4}{3}}+ \dfrac{1}{16}x^{-\frac{4}{3}}

For the Interval 1\leq x\leq 8

Length of the Curve =\int\limits^8_1 {\sqrt{\dfrac{1}{2}+x^{\frac{4}{3}}+ \dfrac{1}{16}x^{-\frac{4}{3}} } } \, dx\\

Using T1-Calculator

=\sqrt\frac{387}{20}

What is the volume of a <br> cylinder with height of 11 in and diameter of 6 inches
nika2105 [10]

Answer:

\boxed{V=99\pi\ in^3\approx310.87\ in^3}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

We have the diameter 2r = 6 in → r = (6 : 2) in = 3 in

and the height H = 11 in. Substitute:

V=\pi(3)^2(11)=99\pi\ in^3

\pi\approx3.14

V\approx99\cdot3.14=310.87\ in^3
