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.

Answer: No, absolutely not,

Step-by-step explanation: 6x2 = 12, so you have to multiply by 2 on each side. 1x2=2, so the equivilent ratio is 12:2!

**Answer: Nope**

**Step-by-step explanation: No, because you can see they multiply 1 x 3 to get to 3, but if you multiply 6 x 3, it equals 18, not 12. (6 x 2 = 12) but they have to have the same denominator and numerator to be equivalent. Therefore, no, they are not equivalent. **

B is the midpoint of AC Find AB, BC and AC.

**Step-by-step explanation:**

Since B is the midpoint of AC. So,

AB = BC

12x - 12 = 4x + 28

12x - 4x = 28 + 12

8x = 40

x = 40/8

x = 5

Now,

AB = BC = 4(5) + 28

= 20 + 28

= 48 cm

Now

AC = AB + BC

AC = 48 + 48

AC = 96 cm

If y ♾x and y = 2 when x = 8, then y = 3 when x =

**Answer:**

12

**Step-by-step explanation:**

The Constant (K) is equal to 8/2 aka 0.25 making the formula now y = 0.25 × x

We have y as 3 so

3 = 0.25 × x we take the 0.25 to the other side by dividing on both sides.. this makes it cancel out on the right.

x is now equal to 3/0.25 which is 12. X = 12

A middle school principal is signing the diplomas of the school's graduating eighth graders.

She previously signed 37 diplomas. Now, she is signing more diplomas at a rate of 0.5 per

second. If the principal signs diplomas for 60 seconds, what will the total number of signed

diplomas be?

**Answer: 67 diplomas**

**Step-by-step explanation:**

0.5 diplomas per second = 1 diploma per 2 seconds

60/2 = 30

30+37 = 67

Correct me if I am incorrect

**An equation that shows how the total number of diplomas signed depends on the number of seconds the principal spends signing them is y = 37 + 0.5x.**

**What is an equation?**

**An equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.**

**It is vital to note that an equation is a mathematical statement which is made up of two expressions that are connected by an equal sign.**

**In this case, let x be number of seconds the principal spends signing them. The principal already signed 37 diplomas. Th equation to illustrate this is 37 + 0.5x.**

The **shortest** distance between the **line** y = 2x+4 and the point at (0.0) is 1.8 units option **(A) **is **correct**.

A **straight** line is a **combination** of endless **points **joined on both sides of the point.

The **slope** 'm' of any** straight **line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The equation of the line is:

y = 2x + 4

Or

2x - y + 4 = 0

The **point **is (0, 0)

As we know, the formula for the **shortest **distance between the **line **and a point:

D = |ax + bx + c|/√(a²+b²)

Plug x = 0 and y = 0

a = 2, b = -1, and c = 4

D = |2(0) + -1(0) + 4|/√(2²+(-1)²)

D = 4/√5

D = 1,78 ≈ 1.8 units

Thus, the **shortest** distance between the **line** y = 2x+4 and the point at (0.0) is 1.8 units option **(A) **is **correct**.

According to the Rational Root Theorem, the following are potential roots of f(x) = 2x2 2x â€" 24. â€"4, â€"3, 2, 3, 4 Which are actual roots of f(x)?.

**Rational root theorems **are used to determine the **potential roots **of a **polynomial function**

The **function **is given as:

[tex]f(x) = 2x^2 + 2x - 24[/tex]

Expand

[tex]f(x) = 2x^2 + 8x - 6x - 24[/tex]

Expand

[tex]f(x) = 2x(x + 4) - 6(x + 4)[/tex]

Factor out x + 4

[tex]f(x) = (2x -6)(x + 4)[/tex]

Set to 0

[tex](2x -6)(x + 4) = 0[/tex]

Split

[tex](2x -6) = 0\ or\ (x + 4) = 0[/tex]

Make x the subject in both cases

[tex]2x = 6\ or\ x= -4[/tex]

Solve for x

[tex]x = 3\ or\ x= -4[/tex]

So, the **actual roots **are 3 and -4

Recall that, the **function **is:

[tex]f(x) = 2x^2 + 2x - 24[/tex]

For a **function**,

[tex]f(x) = px^n + ax^{n-1} +.......+q[/tex]

According to **rational root theorem**, the **roots **of f(x) are:

[tex]Roots = \pm \frac{Factors\ of\ q}{Factors\ of\ p}[/tex]

The **roots **of 24 are:

[tex]24 = \pm1, \pm2, \pm 3, \pm 4, \pm 6, \pm 8, \pm12,\pm 24[/tex]

The **roots **of 2 are:

[tex]2 = \pm1, \pm2[/tex]

So, the **possible roots **are:

[tex]Roots = \frac{\pm1, \pm2, \pm 3, \pm 4, \pm 6, \pm 8, \pm12,\pm 24}{\pm 1, \pm 2}[/tex]

This gives:

[tex]Roots = \pm1, \pm2, \pm 3, \pm 4, \pm 6, \pm 8, \pm12,\pm 24,\pm0.5, \pm1, \pm 1.5, \pm 2, \pm 3, \pm 4, \pm6\pm 12[/tex]

Remove **repetitions**

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
