Find the volume of the solid whose base is the circle x2+y2=25 and the cross sections perpendicular to the x-axis are triangles
ivanzaharov [21]

Triangles with height h and base b, with b=h have area \dfrac{b^2}2.

Such cross sections with the base of the triangle in the disk x^2+y^2\le25 (a disk with radius 5) have base with length

b(x)=\sqrt{25-x^2}-\left(-\sqrt{25-x^2}\right)=2\sqrt{25-x^2}

i.e. the vertical (in the x,y plane) distance between the top and bottom curves describing the circle x^2+y^2=25.

So when x=4, the cross section at that point has base

2\sqrt{25-16}=6

so that the area of the cross section would be 6^2/2 = 18.

In case it's relevant, the entire solid would have volume given by the integral

\displaystyle\int_{-5}^5\frac{b(x)^2}2\,\mathrm dx=4\int_0^5(25-x^2)\,\mathrm dx=\frac{1000}3

Juan is determining the volume of a box using the expression 7.2*8.4*12.8 how many digits will be shown to the right of the deci
beks73 [17]

Answer:

Juan will have 3 digits after decimal.

Step-by-step explanation:

A number having one digit after decimal when multiplied by another number having single digit after decimal, we get a number having two digits after decimal.

Example:

0.2 × 0.6 = 0.12

0.3 × 0.3 = 0.09

Now we have to find the volume of a box having dimensions 7.2 units by 8.4 units by 12.8 units.

Volume = 7.2×8.4×12.8 [Each number having one digit after decimal]

             = 774.144 unit³ [Number with 3 digits after decimal]

Therefore, Juan will have 3 digits after decimal in the final answer.

What is through :(0,5) and (-5,2)
Murljashka [212]

Answer:

y = 3/5x + 5

Step-by-step explanation:

Gradient of the line

\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\\\\frac{2 - 5}{-5 - 0}\\\\\frac{-3}{-5}

\frac{3}{5}

y = 3/5x + c

Substitute either point in to find c

y = 3/5x + c at (0,5)

5 = 3/5(0) + c

5 = 0 + c

5 = c

y = 3/5x + c at (-5,2)

2 = 3/5(-5) + c

2 = -3 + c

2 + 3 = c

5 = c

y = 3/5x + c

Replace c with 5

y = 3/5x + 5
