Which system of equations models the paths of the two skaters? y = 0.08x2-1.6x+13 and y = 0.08(x-10)2+5 y = 0.08x2-1.6x+13 and y = 1.6(x-10)2+5 y = 0.08x2-1.6x+13 and y = 0.8(x-10)2+5 y = 0.08x2-1.6x+13 and y = 5(x-10)2+5
The system of equations models the paths of the two skate is y = 0.08x²-1.6x+13 and y = 5(x-10)²+5. The correct option is b.
What is quadratic equation?The equation with second degree of an unknown variable x, y, m, n, or p is called the quadratic equation.
David starts at (20, 13) and skates along a path that can be modeled by a quadratic equation with a vertex at (10, 5).
Vertex form of quadratic equation is
y =a (x -h)² +k where (h,k) is the vertex.
We plug in (10,5) for h and k
y= a (x -10)² +5
Now plug in (20,13) in the above equation and find out 'a'
13 = a (x -10)² +5
13 = a(10)² +5
13 = 100a + 5
Solving for a, we get
a = 0.08
Substitute 0.08 for 'a' then the equation becomes
y= 0.08 (x -10)² +5
Thus, the correct option is b.

If r is a commutative ring, show that the characteristic of r[x] is the same as the characteristic of r.
If R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.
What is a commutative ring?In ring theory, a commutative ring can be defined as a ring in which the multiplication operation is considered to be commutative in nature.
Let R represent a commutative ring with characteristic K.
Therefore, we have: Kr = 0∀r ∈ R.
Assuming f(x) ∈ R(x)
Then, f(x) would be given by: [tex]a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0=0[/tex]
Also, in some instances ai ∈ R and n ∈ N.
Finally, we would have:
[tex]Kf(x) = K(a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0)\\\\Kf(x) = Ka_n x^n + Ka_{n-1} x^{n-1} +.......+ Ka_1 x^1 +Ka_0\\\\Kf(x) = 0\times x^n + 0\times x +.......+ 0[/tex]
Kf(x) = 0.
Therefore, we can infer and logically deduce that if R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.

What is complex number?A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of number is written together. For example,
a+bi
Here, (a) is the real part while (b) is the imaginary part.
The complex number which need to convert into its polar representation is,
n=-4i
It can be rewritten as,
n=0-4i
The radius r of the polar form is,
r²=0²+(-4)²
r²=0+16
r=4
The value of cos theta is,
tan θ=0/-4
θ=tan⁻¹(0)
θ=π

The tree in jacob's yard casts a shadow that is 27 feet long. jacob is 5 feet tall and casts a shadow that is 4.5 feet long. the two triangles formed are similar because the angle to the sun is the same. what is the height of the tree?
By using the fact that the two triangles are similar, we will conclude that the height of the tree is 30ft
How tall is the tree?
If the two triangles are similar, then the quotient between the height and the shadow length must be the same for both of them.
Then if H is the height of the tree we can write:
H/27ft = 5ft/4.5ft
Now we can solve this for H, we will get:
H = (5ft/4.5ft)*27ft = 30ft
So we can conclude that the height of the tree is 30ft.

Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m. which group describes 16% of the oarfish population? select each correct answer.
Answer:
Explanation:
oarfish that are shorter than 5 m
Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99
This indicates that the sample mean is lower than the population mean
Therefore,
- 0.99 = (x - 6.5)/1.5
- 0.99 × 1.5 = x - 6.5
- 1.5 = x - 6.5
x = - 1.5 + 6.5
x = 5m
The correct answer is
oarfish that are shorter than 5 m

By using the given ratio, we will see that the diagonal measures 50 inches.
How to get the diagonal of the screen?First, we know that the ratio between length and width is 16:9, and the length is 43.6 inches, then the width will be:
W = (9/16)*43.6 inches = 24.5 in
Now, the diagonal will be equal to the hypotenuse of a right triangle with catheti of 43.6 in and 24.5 in, by using Pythagorean's theorem we get:

Which expression represents the volume of the prism? 10x3 cubic units 15x2 cubic units 20x3 cubic units 30x2 cubic units
The expression that represents the volume of the prism is 30x² cubic units.
Option D) is the correct answer.
What is a prism?A prism is simply a solid geometric with two polygonal faces laying in parallel planes and with the other faces parallelograms.
Volume of a prism is expressed as;
Volume = base area × height
Also, the base area is expressed using the area of a trapezoid.
Hence,
Base area = (1/2) × h( a + b )
Now, let;
h = xa = xb = 2xBase area will be;
Base area = (1/2) × h( a + b )
Base area = (1/2) × x( x + 2x )
Base area = (1/2) × 3x²
Base area = 3x²/2
Now volume will be;
Volume = base area × height
Volume = 3x²/2 × h
So, let h be 20 units
Volume = 3x²/2 × 20uniit
Volume = 60x²/2
Volume = 30x² cubic units
Therefore, the expression that represents the volume of the prism is 30x² cubic units.

The answer is 3 out of the variable terms.
What are Binomial squared?The square of a binomial is the sum of the square of the first terms, then multiply the product of the two terms after that the square of the last term.
We have,
3x² + 18x - 8= 0
Move the constants to the right side.
3x² + 18x = 8
Take Factor 3 out of the variable terms.
3(x²+6x)=8
Add 27 to both sides of the equation.
3(x²+6x+9)=8+27
3(x²+6x+9)=35
Write the polynomial as a binomial squared.
