Answer:
Long One is 16

Short One is 4!!

A=base+base/2 * height

A=80

16+4/2 = 10

10 * 8 = 80!!

Short One is 4!!

A=base+base/2 * height

A=80

16+4/2 = 10

10 * 8 = 80!!

**Answer:**

59.44 units²

**Step-by-step explanation:**

The area of each triangular section can be computed from the side length (5 units) and the central angle (72°) as ...

... section area = (1/2)sin(72°)·5² ≈ 12.5·0.951057 ≈ 11.8882 . . . units²

Then 5 such sections will have an area of ...

... pentagon area = 5·11.8882 units² = **59.4410 units²**

_____

*Comment on central angle*

The central angles total 360°. There are 5 equal sections, so the central angle for each of them is 360°/5 = 72°.

*Comment on area formula*

It can be occasionally handy to know that the area of a triangle can be computed from the lengths of adjacent sides and the angle between them. The formula for sides of length "a" and "b" and angle β is ...

... A = (1/2)ab·sin(β)

(b) find the middle term in the expansion of

(1/x+√x)^4 and simplify your unswer.

(c) determine the coefficient of x^11 in the expansion of (x^2 +1/x)^10, simplify your answer.

**Answer:**

a) .

b) The middle term in the expansion is .

c) The coefficient of is 120.

**Step-by-step explanation:**

Remember that the binomial theorem say that

a)

Expanding we have that

symplifying,

.

b) The middle term in the expansion of correspond to k=2. Then .

c)

Since we need that 11=20-3k, then k=3.

Then the coefficient of is

**Answer:**

B & D

**Step-by-step explanation:**

**Volume is calculated as:**

**For (a):**

**For (b):**

**For (c):**

**For (d):**

**There's no need to check for (e)**

**Option b and d answers the question**

Using the **volume**of a **rectangular****prism**to examine the **volumes**of the **prism****,**the two prisms with a **volume**of **36cm³**are **B**and **D**

__Recall____:__

*Volume**of**a**rectanglular**prism**=**Length**×**width**×**Height*

__Prism____A____:__

*Length**=**3cm**;**Height**=**5cm**;**Width**=**4cm*

Volume = 3cm × 5cm × 4cm = **60****cm³**

__Prism ____B____ :__

*Length = 3cm ; Height =**3**cm ; Width = 4cm*

**Volume = 3cm × ****3****cm × 4cm = ****36**** cm³**

__Prism C :__

*Length =**4**cm ; Height =**3**cm ; Width =**2**cm*

**Volume = ****4****cm × ****3****cm × ****2****cm = ****24**** cm³**

__Prism ____D____ :__

*Length =**2**cm ; Height =**6**cm ; Width =**3**cm*

**Volume = ****2****cm × ****6****cm × ****3****cm = ****36**** cm³**

__Prism ____E____ :__

*Length = 3cm ; Height = 5cm ; Width = 4cm*

**Volume = ****4****cm × ****2****cm × ****2****cm = ****16**** cm³**

Hence, the two **rectangular****prisms**with a **volume**of **36cm³**are **B**and **D****.**
