4,500 items are made every 4 hours.

5,625 items are made every 5 hours.

Step-by-step explanation:

when you multiply 1125 by for it will equal 4500 and when you multiply 1125 by 5 it will equal 5625

What is the solution set of {x | x < -3} ∩ {x | x > 5}?
valentinak56 [21]

Answer:

the empty set  {∅}

Step-by-step explanation:

{x | x < -3} ∩ {x | x > 5} is giving us

(-∞, -3) intersecting (5, ∞).

Since those two intervals do not intersect the solution is the empty set

Find the volume and tell me if cavalieri's principle applies to the 2 figures. Show work
Hunter-Best [27]

Answer:

960vol cavalieri's principle applies

Step-by-step explanation:

8x6x20 for vol

"Cavalieri's Principle. If, in two solids of equal altitude, the sections made by planes parallel to and at the same distance from their respective bases are always equal, then the volumes of the two solids are equal "(Kern and Bland 1948)

both same height both equal in all ways

Find the point(s) on the ellipse x = 3 cost, y = sin t, 0 less than or equal to t less than or equal to 2pi closest to the point
Lady_Fox [76]

Answer and Step-by-step explanation:

The computation of points on the ellipse is shown below:-

Distance between any point on the ellipse

(3 cos t, sin t) and (\frac{4}{3},0) is\\\\ d = \sqrt{(3 cos\ t - \frac{4}{3}^2) } + (sin\ t - 0)^2\\\\ d^2 = (3 cos\ t - \frac{4}{3})^2 + sin^2 t

To minimize

d^2, set\ f' (t) = 0\\\\2(3cos\ t - \frac{x=4}{3} ).3(-sin\ t) + 2sin\ t\ cos\ t = 0\\\\ 8 sin\ t - 16 sin\ t\ cos\ t = 0\\\\ 8 sin\ t (1 - 2 cos\ t) = 0\\\\ sin\ t = 0, cos\ t = \frac{1}{2} \\\\ t= 0, \ 0, \pi,2\pi,\frac{\pi}{3} , \frac{5\pi}{3}

Now we create a table by applying the critical points which are shown below:

t            d^{2} = (3\ cos t - \frac{4}{3})^{2} + sin^{2}t

0           \frac{25}{9}<u />

<u />\pi           \frac{169}{9}

2\pi         \frac{25}{9}

\frac{\pi}{3}          \frac{7}{9}

\frac{5\pi}{3}         \frac{7}{9}

When t = \frac{\pi}{3}, x is \frac{3}{2} and y is \frac{\sqrt{3} }{2}. So, the required points are (\frac{3}{2},\frac{\sqrt{3} }{2})

When t = \frac{5\pi}{3}, x is \frac{3}{2} and y is \frac{-\sqrt{3} }{2}. So, the required points are (\frac{3}{2},\frac{-\sqrt{3} }{2})
