Answer:

<u> </u><u>3</u><u> </u>

Step-by-step explanation:

\tt =  > 7.2 \div 2.4 = (7.2 =  \frac{72}{10} =  \frac{36}{5}   ) \div (2.4 =  \frac{24}{10}  =  \frac{12}{5} )

=  >  \frac{36}{5}  \div  \frac{12}{5}  =  \frac{  \cancel {36}^{3} }{ \not \frac{5}{1} }  \times  \frac{ \not  {5}^1 }{ \cancel {12}^{1} }     =  \frac{2}{1}  = 3

Set up the integral that uses the method of disks/washers to find the volume V of the solid obtained by rotating the region boun
Blababa [14]

Answer:

a)\: \frac{3}{2} \pi

b) \:\frac{47}{5} \pi

Step-by-step explanation:

y=3\sqrt x,\:\:y=3,\:\:x=0

a) about the line y = 3

3\sqrt x=3  ⇒  x = 1  is the intersection point

So,

V=\int\limits^1_0\pi(3-3\sqrt x)^2\:dx=\pi\int\limits^1_0(9-18\sqrt x+9x)\:dx=\\\\=\pi(9x-12x^{3/2}+9/2x^2)|^1_0=\pi(9-12+9/2)=\frac{3}{2} \pi

b)  about the line x = 5

y=3\sqrt x  ⇒  x=y^2/9

So,

V = \int\limits^3_0\pi([5-0]^2-[5-y^2/9]^2)\:dy=\pi\int\limits^3_0(25-25+10y^2/9-y^4/81)\:dy=\\\\=\pi(10y^3/27-y^5/405)|^3_0=\pi(10-3/5)=\frac{47}{5} \pi

A sound receiving dish used at outdoor sporting events is constructed in the shape of a paraboloid, with its focus 8 inches from
bixtya [17]

Answer:

w≅8.46ft

Step-by-step explanation:

Data

focus=8

vertex=(0,0)

width=?

depth (y)=3ft

parabola equation: (x-h)^{2}=4p(y-k); then for V=(0,0), x^{2} =4py, be focus(f)=8in;  x^{2} =4*8*y=32y → y=\frac{x^{2} }{32}

we have that y=3ft then 3=\frac{x^{2} }{32}; but 1in≅0.083ft so x^{2} =3*32*0.083=7.968 → x=±2.82, finally w=3*2.82≅8.46ft

Can you find the slope of the line. I have to turn this in today lol
valkas [14]
Answer: 2

Explanation: the slope = rise/run. so if u have two points on the line, count how much it goes up and down divided by how much it goes left and right. so the line goes up 2, left 1, so the slope is 2/1 or 2.

hope this makes sense!
