Answer:
[tex]Domain = (-\infty, \infty)[/tex]
[tex]Range = (-\infty, 4][/tex]
Increasing interval is: [tex](-\infty, 0)[/tex]
Decreasing interval is: [tex](0, \infty)[/tex]
Constant at no interval
Step-by-step explanation:
Given
See attachment for graph
Solving (a): The domain
From, the attached graph, we have:
[tex]y = -x^2 + 4[/tex]
The degree of the polynomial (i.e 2) is even.
Hence, the domain is the set of all real numbers, i.e.
[tex]Domain = (-\infty, \infty)[/tex]
Solving (b): The range
The curve of [tex]y = -x^2 + 4[/tex] opens downward, and the maximum is:
[tex]y_{max} = 4[/tex]
This means that the minimum is:
[tex]y_{mi n} = -\infty[/tex]
Hence, the range of the set is:
[tex]Range = (-\infty, 4][/tex]
Solving (c): Interval where the function increases/decreases/constant
In (a), we have:
[tex]Domain = (-\infty, \infty)[/tex]
Split to 2 (at vertex x = 0)
[tex](-\infty, 0)[/tex] and [tex](0, \infty)[/tex]
So:
The increasing interval is: [tex](-\infty, 0)[/tex]
The decreasing interval is: [tex](0, \infty)[/tex]
The function has a tangent at [tex]x = 0[/tex] but at no interval, was the function constant

Cone 1 is congruent to cone 2 with dimensions given in units as shown below
What is the surface area of cone 2 ?
Please help !! ASAP giving 30 points too correct answer choice
Surface area of cone2 is equals to 96π.
What is surface area?
"Surface area is defined as the sum of the area of all the faces of given three dimensional shape."
Formula used
Surface area of the cone = πr² + πr l
According to the question,
Given,
'r' represents the radius of the cone
'h' represents the height of the cone
'l' represents the slant height of the cone
Cone1 and Cone2 are congruent cones.
⇒Radius of cone1 = Radius of cone2
Slant height of cone1 = Slant height of cone2
As per the given dimensions we get,
Radius of both the cones 'r' = 6units
Slant height of both the cones 'l' = 10units
Substitute the values in the formula we get,
Surface area of the cone2 = π (6)² + π (6) (10)
= 36π +60π
= 96π square units
Hence, surface area of cone2 is equals to 96π.

Solve: y = 2x. y = -x+3. Write the coordinates (__, __)
Answer:
(1,2)
Step-by-step explanation:
y = 2x. y = -x+3
Set the two equations equal
2x = -x+3
Add x to each side
2x+x = -x+x+3
3x = 3
Divide by 3
3x/3 = 3/3
x = 1
Now find y
y =2x = 2(1) = 2
(1,2)
Solve like how you solve the system of equations. System of Equations are to find the intercept of both graphs or to find which coordinate points are solution to both equations.
We are given the equations below:
[tex] \large{ \begin{cases} y = 2x \\ y = - x + 3 \end{cases}}[/tex]
Since both equations are y-isolated and we want to find the coordinate point that both equations have or the coordinate point that is a part of two equations.
[tex] \large{2 x = - x + 3}[/tex]
Isolate the x-term by adding both sides by x.
[tex] \large{2x + x = - x + 3 + x} \\ \large{3x = 3}[/tex]
Divide both sides by 3 so we can finally get the x-isolated equation.
[tex] \large{ \frac{3x}{3} = \frac{3}{3} \longrightarrow x = 1 }[/tex]
Next step is to find the value of y. x-term and y-term both have relations. That means when substituting x-term, we get y-term. Therefore, substitute x = 1 in any given equations. It is not necessary to substitute both, only one is fine. I will choose the first equation to solve for y-value.
[tex] \large{y = 2x}[/tex]
Substitute x = 1:
[tex] \large{y = 2(1) \longrightarrow y = 2}[/tex]
The value of y is 2 when x is 1. Since we want the answer to be in coordinate form or ordered pair. From (x,y) - we get (1,2).

En el cumpleaños de Manolito se inflaron 144 globos. Los 2/9 de los globos eran rojos; los 5/18, verdes y 1/6 eran amarillos. ¿Cuántos globos eran de otros colores?
Answer:
48 globos
Step-by-step explanation:
De la pregunta anterior, se nos dice que:
En el cumpleaños de Manolito se inflaron 144 globos.
Por eso:
Para globos rojos
2/9 de los globos eran rojos
Número de globos rojos = 2/9 × 144 globos
= 32 globos
Para globos verdes
5/18 eran verdes
Número de globos verdes = 5/18 × 144 globos
= 40 globos
Para globos amarillos
1/6 eran amarillas
Número de globos amarillos = 1/6 × 144 globos
= 24 globos
Tenga en cuenta que:
Número total de globos =
Globos rojos + Globos verdes + Globos amarillos + Otros colores
Otros colores = 144 globos - (globos rojos + globos verdes + globos amarillos)
Otros colores = 144 globos - (32 + 40 + 24) globos
= 144 globos - 96 globos
= 48 globos
Por lo tanto, la cantidad de globos que son de otros colores = 48 globos

In table A, the x value of 4 goes to two different y values
To be a function each x value can only go to one y value
A is not a function
Answer:
27 is the answer
Step-by-step explanation:
We have this proportion....
36 / 12 = x / 9 where x is the model door height
Cross-multiply
36*9 = 12 * x
324 = 12 *x divide both sides by 12
27 = x and that's the model height in centimeters
The Really Spicy Hot Sauce Company decides to make a special-edition, extra-spicy version of its Really Spicy Hot Sauce. Expected demand for the special-edition version of their hot sauce is estimated to be 5000, normally distributed with a standard deviation of 1200. It will cost $2.50 to make each bottle; the bottles are intended to sell for $20. Whatever doesn't sell will be given to employees as a gift, thus earning $0 in revenue. Because it takes 3 years for the hot sauce to fully ferment and mature, the Really Spicy Hot Sauce Company can only make one batch of the special-edition hot sauce. How many bottles should the company make in order to maximize their expected profit? ______________

Polynomial is an expression that consists of indeterminates(variable) and coefficients. The correct option is A.
What are polynomials?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
For the given expression x³ – 7x² – 5x + 35 the factorisation by grouping can be done as,
x³ – 7x² – 5x + 35
Take x² as common from the first two terms, while -5 as common from the last two terms,
= x²(x – 7) –5(x – 7)
Take (x–7) as the common term from the two terms,
= (x² – 5)(x – 7)

What is the VERTEX and what do the coordinates mean in the context of the problem?
please solve algebraically
Answer:
The vertex of this problem is (8,16). This means that the highest height the ball reaches is at t = 8s, and this maximum height is of 16 feet.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
b(x) = - 0.25 x^2 + 4x
Quadratic equation with [tex]a = -0.25, b = 4[/tex].
Vertex:
[tex]x_{v} = -\frac{4}{2(-0.25)} = 8[/tex]
[tex]\Delta = 4^2-4(-0.25)(0) = 16[/tex]
[tex]y_{v} = -\frac{16}{4(-0.25)} = 16[/tex]
The vertex of this problem is (8,16). This means that the highest height the ball reaches is at t = 8s, and this maximum height is of 16 feet.
