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)

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

If the measure of angle 0 is 2pie/3 which statements are true?
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

Answers
Answer:
Jude is correct
Step-by-step explanation:
Our input value is given to us which is 4. Which means we would replace the x values in the function to 4 ==> f(4)= -2(4)^2 + 32 which simplifies to -2(16)+32 which then comes out as 0.
