**Answer 1**

**Answer: (b)**

**Step-by-step explanation:**

A downward parabola graph is given such that it cuts the Y-axis at (0,200)

and x-axis at (5,0) and (20,0)

For the value to be at least 200, the value of x lies between 0 to 15 as the value of y is greater than 200.

[tex]0\leq x\leq 15[/tex]

So, the correct option is (b)

### Answers

**Answer:**

The first option:

[tex]Area = 27units^{2} \\Perimeter = 26 units[/tex]

**Step-by-step explanation:**

The area of a trapezoid can be found by using the following formula where "a" and "b" are the bases and "h" is the height of the trapezoid.

[tex]Area = \frac{(a +b)h}{2} = \frac{3(7 + 11)}{2} = \frac{3(18)}{2} = \frac{54}{2} = 27 units^{2}[/tex]

The perimeter can be found by adding the lengths of all sides. Therefore the perimeter of this trapezoid equals...

Perimeter = 3 + 11 + 5 + 7 = 26 units

Y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.

Someone please help me! I’ve been stuck on this forever!

### Answers

**Answer:**

y = -4/3

**Step-by-step explanation:**

A direct variation equation has the form

y = kx

We need to find the value of k for this situation.

For that, we use the given values of x and y and solve for k.

When x = -18, y = 15.

15 = k × -18

k = 15/(-18)

k = -5/6

Now that we know the value of k for this specific situation, we write the equation of direct variation for our case.

y = -5/6 x

Finally, we find y when x = 1.6 using our equation.

y = -5/6 x

y = -5/6 × 1.6

y = -8/6

y = -4/3

### Answers

**Answer:**

Angle 0 is 6.28/3. or 2.093.

**Step-by-step explanation:**

**Pie is an irrational number, so it will be repeating forever. A simple way to get pie is just 3.14. 3.14 times 2 is 6.28. Divide 6.28 by 3 to get 2.093 repeating, but simplified is 2.093.**

As the **positive [x] values** reaches **zero**, the **[y] values** reach **zero**.

What is the domain and range of the function f(x) = x⁻².

The **domain **and** range** of the function f(x) = x⁻² is

Domain → **(−∞,∞) , {x | x ∈ R}**

Range → **[0,∞) , {y | y ≥ 0}**

We have the following **function **-

**f(x) = 10/x²**

Given is the function -

**f(x) = 10/x²**

Refer to the graph attached. As the **positive [x] values** reaches **zero**, the **[y] values** reach **zero**.

Therefore, as the **positive [x] values** reaches **zero**, the **[y] values** reach **zero**.

[tex] \sqrt{ {(x - 3)}^{3} } - 64 = 0[/tex]

### Answers

**Answer:**

x = 19

**Step-by-step explanation:**

[tex]\sqrt[2]{x-3^3}[/tex] = 64

[tex]\sqrt[2]{x-3^3}[/tex] = 4³

multiply each side by the exponent 2/3 so the radical sign on left is removed

([tex]\sqrt[2]{x-3^3}[/tex])^2/3 = (4³)^2/3

x - 3 = 4²

x - 3 = 16

x = 19
