Answer:

V=π*(2x^3+35x^2+176x+192)units^3

Step-by-step explanation:

This is the correct answer, but on certain tests you might have to distribute the pi in the beginning of the statement. When you do this the statement becomes, 2πx^3+35πx^2+176πx+192π

Answer:

V=π*(2x^3+35x^2+176x+192)units^3

Step-by-step explanation:

V=πr^2h

r=x+8

h=2x+3

V=π*(x+8)^2*2x+3

=π*(x^2+16x+64)*2x+3

=π*(2x^3+32x^2+128x+3x^2+48x+192)

=π*(2x^3+35x^2+176x+192)

Volume of the cylinder=π*(2x^3+35x^2+176x+192)units^3

What is the slope of this line?
nataly862011 [7]

Answer: -\frac{8}{5}

Remember: RISE/RUN (y/x). Lines that are increasing have a positive slope, and lines that are decreasing have a negative slope.

You can find the slope in two ways:

1. Useful if the line is graphed: count the units between 2 points on the line.

  • Let's use the points (-1, 4) and (4, -4).
  • (-1, 4) is 8 units higher than (4, -4) and 5 units to the left of (4, -4).
  • Because the line is decreasing, the slope is negative.
  • Therefore, the slope is -\frac{8}{5}.

2. Useful if the line is not graphed: find the difference between the y-coordinate values divided by the difference of the x-coordinate values.

  • Let's use the points (-1, 4) and (4, -4).
  • \frac{-4 - 4}{4 - (-1)} = \frac{-8}{5}
  • Therefore, the slope is -\frac{8}{5}.

A rectangular parking lot has an area of 2/3 of a square kilometer. The width is 1/2 of a kilometer. What is the length, in kilo
jeka57 [31]
Area = length x width
 replace the known information into the equation:

area = 2/3
width = 1/2

so now the formula looks like:

2/3  = 1/2 x L

to solve for L we divide both sides by 1/2

L = 2/3 / 1/2 which  = 2/3 * 2/1 = 4/3 = 1 and 1/3 km

ms evans went to the store to buy some cupcakes. she brought 129 cupcakes. she wants to put 5 cupcakes in each box.how many boxe
NeTakaya
129 divided by 5 is equal to 25 with a remainder of 4. 

This means that she will need a total of 26 boxes, but only 25 of them will have 5 cupcakes in them. The last one will have 4 cupcakes.

Find the value of x and the value of y.
Elan Coil [88]

Answer:

Step-by-step explanation:

According to the diagram ,

Hypotenuse = 10√3

Opposite = x

Adjacent = y

α = 60

Using SOHCAHTOA ,

Sin α = opp / hyp

Sin 60= x/10√3

√3/2= x/10√3

x = 15

Pythagoras theorem ;

Hypotenuse ^2 = Opposite ^2 +Adjacent ^2

10√3 ^2 = 15^2+ y^2

300 = 225 +y ^2

300 -225 = y^2

75 = y^2

y = √75y

y = 5√3
