Adam has notes of RS.100, RS.50 and RS.10. The ratio of these notes is 2 : 3:5 respectively and the total amount is RS.200,000. Find the number of notes of each kind.
The number of notes of Rs. 100 is 1000, Rs. 50 is 1500, and Rs. 10 is 2500.
The ratio describes the number of times one number contains another. It helps to establish a relationship between two or three quantities.
The ratio between any two quantities is described as a:b. This can also be written as a to b or a/b.
The ratio of RS.100, RS.50, and RS.10 is 2:3:5.
From the given ratio, consider
the number of Rs. 100 is 2xthe number of Rs. 50 is 3xthe number of Rs. 10 is 5x.The total amount is given as RS.200,000. This can be written as,
[tex]\begin{aligned}100\times2x+50\times 3x+10\times5x&=200,000\\200x+150x+50x&=200,000\\400x&=200,000\\x&=\frac{200,000}{400}\\x&=500\end{aligned}[/tex]

The graph represents the function f(x) = x2 + 3x + 2. If g(x) is the reflection of f(x) across the x-axis, g(x) = . (Write the function in standard form. Use ^ to indicate an exponent.)
The reflection of the graph in the x-axis gives the function
g(x) = -x² - 3x - 2
The given function is of the form f(x) = x² + 3x + 2 which represents a parabola.
The vertex of the function is at (-3/2 , -1/4)
The focus is at ( 3/2 , 0 )
The axis of symmetry is 2x+3 = 0 and the directrix is at 2x + 1 = 0
Now when the parabola is reflected along the x-axis we get
the focus at ( -3/2 , 0 )
the vertex is at (-3/2 , 1/4)
Axis of symmetry remains the same
The directrix becomes 2y-1 =0
The red graph denotes the function f(x) while the blue graph denotes the function g(x) reflected on the x-axis.

Define the formula for a parabola (a quadratic function) that has horizontal intercepts (roots) at x = −7 and x = 5 and passes through the point (0, −2)
The equation for the parabola with the given characteristics is:
y = (2/35)*(x + 7)*(x - 5)
How to get the equation of the parabola?We know that for a parabola that has the zeros x₁ and x₂, and a leading coefficient a, can be written as:
y = a*(x - x₁)*(x - x₂)
In this case, the roots (zeros) are at X =-7 and x = 5
Then we can write:
y = a*(x + 7)*(x - 5)
Now we also know that it passes through the point (0, -2), then we can write:
-2 =a*(0 + 7)*(0 - 5)
-2 = a*-35
2/35 = a
Then the equation for the parabola is:
y = (2/35)*(x + 7)*(x - 5)

Determine an nth degree polynomial that satisfies the aforementioned conditions.
The polynomial of p(x) is 20/13(x³+4x²-9x-36) with the satisfying's conditions degree 3.
Given that,
An nth degree polynomial p meets the requirements listed below:
p is of degree 3.
-3 is a multiplicity 1 zero of p.
-4 is a zero, with multiplicity 1, of p.
3 is a root, with multiplicity 1, of p.
p(-2)=-40
We have to determine an nth degree polynomial that satisfier the conditions.
Let the polynomial be p(x) whose zero are -3,-4 and 3.
a be the coefficient.
p(x)=a(x+3)(x+4)(x-3)
p(x)=a(x²-3²)(x+4)
p(x)=a(x²-9)(x+4)
p(x)=a(x³+4x²-9x-36)
Now, take x=-2
p(-2)=a((-2)³+4(-2)²-(-2)-36)
-40=a(-8+16+2-36)
-40=a(-26)
a=-40/-26
a=40/26
a=20/13
We get,
p(x)=20/13((x+3)(x+4)(x-3))
p(x)=20/13(x³+4x²-9x-36)
Therefore, the polynomial of p(x) is 20/13(x³+4x²-9x-36) with the satisfying's conditions degree 3.
