For the graph of the cubic root function, the function has no intercept.
What is the cartesian plane?The cartesian plane is a two-dimensional coordinate plane that is formed when two parallel lines meet. The X-axis is the horizontal line, and the Y-axis is the vertical line. On the Cartesian plane, the coordinate point (x, y) indicates that the point is on the right of the origin if the sign of x is positive; otherwise, the point is on the left of the origin.
Given the graph of the cubic root function,
The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
the function of the graph is y = ∛x
when x = 0, y = 0

is 2/5 and 12/20 equivalent?explain your answer
Answers
Answer:
no
Step-by-step explanation:
2/5 * 6/6 = 12/30 which is not equal to 12/20 and if we make the denominator same i.e 2/5 * 4/4 = 8/20 which is again not equal to 12/20
Answer:
Hello! :) I hope I’m correct!!
Step-by-step explanation:
2/5 and 12/20 are NOT equivalent.
First we have to find out what times 2 gives you 12
2x6=12
It will be 6.
Since you did this for the numerator, you have to do the same for the denominator.
(Multiply both the numerator and denominator by 6)
5x6=30
For our numerator we got 12 and for our denominator we have 30
Which will be 12/30 not 12/20
2/5 is equivalent to 12/30 but not 12/20.
So therefore the answer to your question will be NO, 2/5 and 12/20 are not equivalent.

(2) - x=0 and x=150
(3) - A negative, "-"
(4) - y=-1/375(x–75)²+15
(5) - y≈8.33 yards
Step-by-step explanation:
(1) - What shape does the flight of the ball take?
The flight path of the ball forms the shape of an upside-down parabola.
\(\hrulefill\)
(2) - What are the zeros (x-intercepts) of the function?
The zeros (also known as x-intercepts or roots) of a function are the points where the graph of the function intersects the x-axis. At these points, the value of the function is zero.
Thus, we can conclude that the zeros of the given function are 0 and 150.
\(\hrulefill\)
(3) - What would be the sign of the leading coefficient "a?"
In a quadratic function of the form f(x) = ax²+bx+c, the coefficient "a" determines the orientation of the parabola.
If "a" is positive, the parabola opens upward. This is because as x moves further away from the vertex of the parabola, the value of the function increases.If "a" is negative, the parabola opens downward. This is because as x moves further away from the vertex, the value of the function decreases.Therefore, the sign would be "-" (negative), as this would open the parabola downwards.
\(\hrulefill\)
(4) - Write the function
Using the following form of a parabola to determine the proper function,
y=a(x–h)²+k
Where:
(h,k) is the vertex of the parabolaa is the leading coefficient we can find using another pointWe know "a" has to be negative so,
=> y=-a(x–h)²+k
The vertex of the given parabola is (75,15). Plugging this in we get,
=> y=-a( x–75)²+15
Use the point (0,0) to find the value of a.
=> y=-a(x–75)²+15
=> 0=-a(0–75)²+15
=> 0=-a(–75)²+15
=> 0=-5625a+15
=> -15=-5625a
∴ a=1/375
Thus, the equation of the given parabola is written as...
y=-1/375(x–75)²+15
\(\hrulefill\)
(5) - What is the height of the ball when it has traveled horizontally 125 yards?
Substitute in x=125 and solve for y.
y=-1/375(x–75)²+15
=> y=-1/375(125–75)²+15
=> y=-1/375(50)²+15
=> y=-2500/375+15
=> y=-20/3+15
=> y=25/3
∴ y≈8.33 yards

During the year, Poch Co. incurred cost of goods sold of $59,823 million on net sales of $76,643 million. To find Poch's return on sales ratio, we need to divide the cost of goods sold by the net sales and multiply by 100.
The calculation would be:
Return on Sales Ratio = (Cost of Goods Sold / Net Sales) * 100
Plugging in the given values:
Return on Sales Ratio = ($59,823 million / $76,643 million) * 100
Now, let's solve the calculation:
Return on Sales Ratio = (0.7807) * 100
Return on Sales Ratio ≈ 78.07%

As the result the number of students per class was 10 more than they planned if there are 1200 grade 9 students in the school determine the current number of classrooms and the number of students per class
Answers
The current number of classrooms is 24, and the number of students per class is 70 if there were a total of 1200 students.
Let us assume that the number of classes = x
Number of students per class = 1200/x
Number of classrooms planned = x - 4
Number of students planned per class = 1200/ x+10
Total number of students = 1200
By using the above data, the equations will be written as:
(1200 / x-4) = (1200/x) +10
By multiplying the equation 2 we get:
1200x = 1200x + \(x^{2}\) - 4800 - 40x
\(x^{2}\) - 480- 4x = 0
(x-24) (x+20) = 0
x = 24
Number of rooms built = x =24
Number of students per class = (1200/24-10) = 60 students
Therefore, we can conclude that the current number of classrooms is 24, and the number of students per class is 60 + 10 =70.

How to determine a missing length in a system of two similar triangles and the perimeter of a triangle
In this question we need to determine the length of side UV, which is part of a system of two similar triangles. Two triangles are similar if each pair of corresponding internal angles are congruent, but each pair of sides are not congruent though proportional. This system can be described well by following proportion formula:
x / 23 = 24 / 20 = 36 / 30
x / 23 = 6 / 5 = 6 / 5
x / 23 = 6 / 5
x = (6 / 5) × 23
x = 27.6
The perimeter of the triangle TUV is the sum of the sides TU, UV, TV, thus:
p = TU + UV + TV
p = 24 + 27.6 + 36

The length of the side m are obtained using the theorem of Pythagoras and proportional triangles to give;
a) m ≈ 28.4
b) m ≈ 12.09
c) m ≈ 9.38
Which theorem can be applied to find the value of m?a) The given triangle, is a right triangle.
The length of the legs of the triangle are; 33 and 56.
According to Pythagorean theorem, the length of the hypotenuse side, l, is therefore;
l = √(33² + 56²) = 65
From the formula for the area of a triangle, we have;
Area of a triangle, A, equals half the base length multiplied by the height.
A = 0.5 × Base length × Height
For the right triangle, we have;
A = 0.5 × Leg 1 × Leg 2
Which gives;
A = 0.5 × 33 × 56 = 924
However;
A = 0.5 × l × m
Where;
l = The hypotenuse = The base length = 65
m = The height of the triangle
Which gives;
A = 0.5 × 65 × m = 924
m = 924/(0.5 × 65) ≈ 28.4
m ≈ 28.4b) The side m is parallel the 14 units long side.
The proportion the side m divides a side of the triangle = 3 and 19
Given that the triangle formed by m is proportional to the larger triangle, we have;
m/14 = 19/(19+3)
m = 14 × 19/(19+3) ≈ 12.09c) From the proportionality of similar triangles, we have;

Answers
The number of managers are in this survey = 96
Let us assume that A represents the set of managers with BS degree and B represents the set of managers with masters degree.
46 managers have a masters degree.
⇒ n(A) = 46
60 managers have a B.S. degree
⇒ n(B) = 60
20 have both a masters and bs degree.
⇒ n(A ∩ B) = 20
10 managers have neither degree
⇒ n(A ∪ B)c = 10
We know that the set formula,
n(P U Q) = n(P) + (n(Q) – n (P ⋂ Q)
So, n(A ∪ B) = n(A) + n(B) – n (A ⋂ B)
n(A ∪ B) = 46 + 60 - 20
n(A ∪ B) = 86
Let n(S) be the be the total managers are in this survey.
n(S) = n(A ∪ B) + n(A ∪ B)c
n(S) = 86 + 10

Answers
The Kutta-Joukowski theorem, which is represented by equation (3.140), was originally derived for the case of a lifting cylinder. However, it can also be applied to a two-dimensional body of arbitrary shape, as stated in section 3.16.
A more detailed explanation of the answer.
To make a physical argument for this generalization, we can draw a closed curve around the body.
The key is to draw the curve far enough away from the body such that the body appears as a very small speck in the middle of the domain enclosed by the closed curve.
By doing this, we are essentially treating the body as a point object at the center of the curve. Since the body is now a very small speck in comparison to the large domain, its specific shape becomes insignificant to the overall flow around it.
Therefore, the lifting force calculations derived from the Kutta-Joukowski theorem for the lifting cylinder should also apply to the two-dimensional body of arbitrary shape, as long as the body is small in comparison to the domain enclosed by the closed curve.
This physical argument allows us to accept that equation (3.140) can be applied in general to a two-dimensional body of arbitrary shape without requiring a mathematical proof.

Answer:
2x-y+2= 0
Step-by-step explanation:
(-5,-2)=(x1, y1)
(3, 14) =(x2, y2)
now,
slope(m)= y2-y1 / x2-x1
=14+2 / 3+5
= 16 /8
=2 units
passing point = (-5,-2) = x1,y1
now,
eqn of the line can be represented as,
y -y1 = m (x-x1)
y +2 = 2 (x +5)
y+2 = 2x +10
y = 2x+10-8
0 = 2x+2-y
2x-y+2 =0 is the required eqn
