Natali [406]4 years ago

Answer:

<h2><em><u>3. V = 1,498.2</u></em></h2><h2 /><h2><em><u>4. V = 2,813.44</u></em></h2><h2 /><h2><em><u>5. V = 96.293</u></em></h2>

Step-by-step explanation:

3. Formula of a Cylinder + Formula of a Cone = Total

V=πr^2h + V=πr^2h

/3 = total

V = 3.14 * 36 * 10 + V = 3.14 * 36 * 10/3

V = 1,130.4 + V = 376.8 = Total

<h2><em><u>V = 1,498.2</u></em></h2>

4. Formula of Cone + Formula of Cone = Total

V=πr^2h

/3 + V=πr^2h

/3 = Total

V = 3.14 * 36 * 8/3 + V = 3.14 * 100 * 8 = Total

V = 301.44 + 2,512 = Total

<h2><em><u>V = 2,813.44</u></em></h2>

5. Formula of a cylinder + formula of a sphere = Total

V=πr^2h + V=4

/3πr^3 = Total

V = 3.14 * 4 * 5 + V = 4/3 * 3.14 * 8

V = 62.8 + V = 33.493 = Total

<h2><em><u>V = 96.293</u></em></h2>

DEFINITELY hope this helped,

Kavitha

Is x + 3 a factor of P(x) = x³ - 5x² + 3x + 9 ? Explain.​
Ksju [112]

Answer:

no

Step-by-step explanation:

using the Factor theorem.

If (x + h) is a factor of f(x) then f(- h) = 0

for factor (x + 3) then evaluate P(- 3)

P(- 3) = (- 3)³ - 5(- 3)² + 3(- 3) + 9 = - 27 - 45 - 9 + 9 = - 72

since f(- 3) ≠ 0 then (x + 3) is not a factor of P(x)

3 An open cone has a vertical angle measuring 40°
belka [17]

Answer:

13.41 cm

Step-by-step explanation:

The radius, height, and HALF of vertical angle makes a triangle.

Where

Radius will be the base of the triangle

Height will be the "height" of the triangle

Top angle will be HALF of vertical angle (40/2 = 20)

From the 20 degree angle, the side "opposite" would be the radius, which is 30. The side "adjacent" would be the height, let it be h.

<em>Which trig ratio relates opposite and adjacent? Yes, that is TAN. Thus we can write:</em>

Tan(20) = opposite/adjacent

Tan(20) = 30/h

h = 30/Tan(20)

h = 13.41

So

The height of the cone would be around 13.41 cm

The perimeter of a garden is 88 feet. The length is 12 feet greater than the width. What are the dimensions of the garden
valina [46]

Answer: length = 28 feet

Width = 16 feet

Step-by-step explanation:

Let L represent the length of the rectangular garden.

Let W represent the width of the rectangular garden.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of a garden is 88 feet. This means that

2(L + W) = 88

Dividing through by 2, it becomes

L + W = 44 - - - - - - - - - - - -1

The length is 12 feet greater than the width. This means that

L = W + 12

Substituting L = W + 12 into equation 1, it becomes

W + 12 + W = 44

2W + 12 = 44

2W = 44 - 12

2W = 32

W = 32/2

W = 16

L = W + 12 = 16 + 12

L = 28
