Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. y = 64x−8x^2,
Mandarinka [93]
We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67<span />

3.4=21 2.5=7. 4.4=؟​
Licemer1 [7]

Answer:

32

Step-by-step explanation:

From the given values

The possible logic could be

if x.y is given

then it is equal to=\frac{(x+y)\times x}{y-3}

For 1st example

3.4=\frac{(3+4) \times 3}{4-3} =\frac{21}{1} =21

For 2nd example

2.5=\frac{(2+5) \times 2}{5-3} =\frac{7 \times 2}{2} =7

⇒4.4=\frac{(4+4)\times 4}{4-3} =32

   __________

   |                     |

x-3|                    |     x-3

   |                     |

   |__________

           4x

Add all sides together to get perimeter

2(4x)+2(x-3)=10x-6

Angle G is a circumscribed angle of circle E. Major arc FD measures 280°.
mixer [17]

Answer:

The answer is 40°

Step-by-step explanation:

Solution

Now,

The Measure of major arc FD = 280°

Thus,

One complete angle measure 360°

Then

m∠FED = 360 - 180

m∠FED = 80°

Thus,

FE = DE ( the same circle Radius)

∠EFD = ∠EDF (  opposite angles to equal sides are equal)

Now

Applying angle sum property of a triangle in ΔEFD

∠EFD + ∠EDF + ∠FED = 180°

∠EFD + ∠EFD + 80 = 180

2∠EFD = 100

∠EFD = 50°

Hence, GF is tangent to the circle and the tangent always make right angles with the radius of the circle.

∠EFG = 90°

∠GFD + ∠EFD = 90°

∠GFD + 50 = 90

∠GFD = 40°

Therefore, The measure of the angle GFD is 40°
