The polynomial functions in their expanded form is given as follows. It is right to state that there are no breaks in the domain of h(x).
In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.
For instance, the polynomial 3x+4 has an exponent of 1.
Part A: F(x) has zero at 2 and multiplicity of 1; and
1 at the multiplicity of 2
f(x) = x-2) (x-1)²
= (x-2) (x² - 2x + 1)
= x³ - 4x² + 5x -2
Part B: h (x) = [tex]\left \{ {{x^3 -4x^2 + 5x -2; X < 0} \atop {\sqrt[3]{x-2} ; X\geq 0 }} \right.[/tex]
The domain of X is X ∈ R
Hence it is correct to state that there are no breaks in the domain of h(x).

Determine what type of model best fits the given situation: principal p is invested at an annual interest of rate r, compounded k times a year for t years.
The most appropriate model for a given situation is exponential.
What is compound interest?The interest you earn on interest is known as compound interest.Compound interest is a use of exponential functions. A specific sum is added to the account balance each time money is invested (or lent out). Interest is the amount of money that is added to the balance. The sum will continue to accrue interest after that interest has been added during the subsequent compounding period.In the settings of investments and savings, compound interest is used. A = P(1 + RT) is the formula for simple interest. The next section contains a definition of the variables. This indicates that the account value is the sum of the initial investment amount multiplied by one and the rate multiplied by the time.The most appropriate model for a given situation is exponential.

Step-by-step explanation:
The sum of two functions is the sum of their definitions.
Application(f +g)(x) = f(x) +g(x)
(f +g)(x) = √(x -2) +√(x)
Note: the radicals can only be combined if they can be reduced to a form that has the same expression under the radical. Here, that is not the case, so there is no way to simplify the sum.
Find the rectangular coordinates of the point with spherical coordinates (rho,θ,ϕ) : (4,π6,2π3)
The spherical coordinate (4,6π,2π/3) is (5,2π3,0.927) in spherical coordinates.
I’m going to assume that your values are in the form of:
(r,θ,z)=(4,6π,2π/3)
where
(r,θ)are the polar coordinates of the point’s projection in the xy-plane
z is the usual z-coordinate in the Cartesian coordinate system
Now solving for Cartesian coordinates:
x=rcosθ=4cos(6π)=4(0.86)=3.44
y=rsinθ=4sin(6π)=2
Now for spherical transformation, note that:
(ρ,θ,ϕ)
ρ is the distance between P and the origin
θ is the same angle used to describe the location in cylindrical coordinates
ϕ is the angle formed by the positive z-axis and line segment from the origin and point in space, note that0≤ϕ≤π
OK, now that we have that out of the way, let’s compute:
ρ=r2+z2 = 5
θ=θ=6π
ϕ=arccos(zr2+z2−−−−−−√)=arccos(35)≈0.927rad
The spherical coordinate (4,6π,2π/3) is (5,2π3,0.927) in spherical coordinates.

Elliott is standing at the top of a store escalator that leads to the ground floor below. the angle of depression from the top of the escalator to the floor is 42.51°, and the escalator is 16 feet long. how far is the top of the escalator from the ground floor? round your answer to the nearest foot.
By using what we know about right triangles, we conclude that the height is 11ft.
How far is the top of the escalator from the ground floor?We can think of this as a right triangle.
Where the length of the escalator is the hypotenuse
We know that the angle of depression is 42.51°, then the top angle of our right triangle is:
90° - 42.51° = 47.49°
Now, the height of the top of the escalator would be the adjacent cathetus to said angle, then we can use the relation:
cos(a) = (adjacent cathetus)/(hypotenuse)
Replacing what we know:
cos(47.49°) = height/16ft
cos(47.49°) *16ft = height = 10.8ft
Rounding to the nearest foot, we get:
height = 11ft

The factoring the equation (a + 1)² - 4b² we get (a+1+2b)(a+1-2b).
What is the factoring function of (a + 1)² - 4 b²?Given: (a + 1)² - 4b²
Apply Perfect Square Formula, and we get
(a + b)² = a² + 2 a b + b²
(a + 1)² = a² + 2a1+1²
= a² + 2a1 + 1² - 4 b²
simplifying the equation, we get
a² + 2a1 + 1² = a² + 2a + 1
= a² + 2a + 1 - 4b²
Factor, a² + 2a + 1 = (a + 1)²
= (a + 1)² - 4 b²
Simplify 4 b² = (2 b)²
= (a + 1)² - (2b)²
Apply the Difference of Two Squares Formula, and we get
x² - y² = (x + y)(x - y)
(a + 1)² - (2b)² = ((a + 1) + 2b)((a + 1) - 2 b)
simplifying the equation, we get
= ((a + 1) + 2b)(a + 1) - 2 b)
= (a + 1 + 2b)(a + 1 - 2b)

Answer: 1547.10
Step-by-step explanation: Since you are not in a physics class, in which case requires the usage of the radioactive decay formula, definite integrals, and natural logarithms) but an Algebra class which deploys the usage of percentages, this should be rather simple.
I believe they want you to find 27% of the half life of Carbon-14 since it is below 50%. To find the percent of a number (in this case 27%), you multiply the number by 0.27.

The total surface area of the shape is 10053 cm²
Calculating Surface areaFrom the question, we are to determine the surface area of the shape
The surface area of the shape = Surface area of hemispherical part + Surface are of the cylindrical part
∴ Surface area of the shape = 2πr² + 2πrh + πr²
Where r is the radius
and h is the height of the cylindrical part
From the given information.
r = 20
h = 50
Putting the parameters into the equation, we get
Surface area of the shape = 2π(20)² + 2π(20)(50) + π(20)²
Surface area of the shape = 2π×400+ 2π×1000 + π×400
Surface area of the shape = 800π+ 2000π + 400π
Surface area of the shape = 3200π cm²
Surface area of the shape = 10053.096 cm²
Surface area of the shape ≈ 10053 cm²

Y=2x^2+2x-4 what is the x intercepts for the parabola
Answer:
Step-by-step explanation:
To find the x intercepts, substitute in 0 for y and solve for x
So,

2(x^2+x-4) = 0
2/2(x^2+x-4) = 0/2
x^2+x-4 = 0
(x-1) (x+2) = 0

A product is something that has undergone one or more multiplications.
Here, we're looking for the final digit of the product of all whole numbers greater than 11 and less than 29.
Next, we have the product as: 12*13*14*15*16*17*18*19*20*21*22*23*24*25*26*27*28
Now take note of the 20 that is present.
Any number multiplied by 20 will result in a zero, so:
Product = 20*(12*13*14*15*16*17*18*19*21*22*23*24*25*26*27*28)
