A polygon with area 10 square units is dilated by a scale factor of k. Find the area of the image for each value of k.

a k=4

square units

b. k=1.5

square units

ck=1

square units

**Answer:**

a = 160 square units

**Step-by-step explanation:**

The **areas **of the** image** are 160, 22.5 and 10 square units

The **area **of the** polygon** is given as:

A =10 square unit

The **area **of the** image** of the** polygon** is calculated as:

[tex]A_k = A * k^2[/tex]

When k = 4, we have:

[tex]A_4 = 10 * 4^2[/tex]

[tex]A_4 = 160[/tex]

When k = 1.5, we have:

[tex]A_{1.5} = 10 * 1.5^2[/tex]

[tex]A_{1.5} = 22.5[/tex]

When k = 1, we have:

[tex]A_{1} = 10 * 1^2[/tex]

[tex]A_{1} =10[/tex]

Hence, the **areas **of the** image** are 160, 22.5 and 10 square units

Calculate the measure of angle ADB if angle ACB is 50 degrees.

**Answer:**

ADB=50°

**Step-by-step explanation:**

Angles subtended by the same segment are equal

Therefore,the **angle **∠[tex]ADB=40[/tex] degree.

**What are the angles?**

An **angle** is a form of **geometrical **shape, that is constructed by **joining **two rays to each other at their end-**points**.

Here given that ∠[tex]ACB=50[/tex] **degree **and we know **alternates **angles are equal so ∠[tex]CAD=50[/tex] **degree**.

And [tex]AD[/tex] is parallel to [tex]BC[/tex].

Therefore, the **diagonals **of a rhombus are at right angled.

So, ∠[tex]AOD=90[/tex] degree

Now, In Δ[tex]AOD[/tex],

∠[tex]ADO+[/tex]∠[tex]DAO+[/tex]∠[tex]AOD=180[/tex] degree

∠[tex]ADO+50+90=180[/tex]

∠[tex]ADO=+140=180[/tex]

∠[tex]ADO=180-140[/tex]

∠[tex]ADO=40[/tex] degree

or

∠[tex]ADB=40[/tex] degree.

Hence, the **angle **∠[tex]ADB=40[/tex] degree.

The height, h, in feet of a piece of cloth tied to a waterwheel in relation to sea level as a function of time, t, in seconds can be modeled by the equation h = 15 cosine (StartFraction pi Over 20 EndFraction t). How long does it take for the waterwheel to complete one turn? 5 seconds 10 seconds 20 seconds 40 seconds.

Solving the **trigonometric equation**, it is found that it takes **40 seconds** to complete one turn.

The **height **is modeled by:

[tex]h(t) = 15\cos{\left(\frac{\pi}{20}t\right)}[/tex]

The **initial height** is [tex]h(0) = 15[/tex], hence, **one turn** is completed when **h(t) = 15.**

[tex]h(t) = 15\cos{\left(\frac{\pi}{20}t\right)}[/tex]

[tex]15 = 15\cos{\left(\frac{\pi}{20}t\right)}[/tex]

[tex]\cos{\left(\frac{\pi}{20}t\right)} = \frac{15}{15}[/tex]

[tex]\cos{\left(\frac{\pi}{20}t\right)} = 1[/tex]

The **length **of one turn is of [tex]2\pi[/tex], and [tex]\cos{(2\pi)} = 1[/tex], hence, the **solution **is found according to:

[tex]\frac{\pi}{20}t = 2\pi[/tex]

[tex]t = \frac{40\pi}{\pi}[/tex]

[tex]t = 40[/tex]

It takes **40 seconds** to complete one turn.
