What is a solution to the system of equations that includes quadratic function f(x) and linear function g(x)? f(x) = 5x2 x 3
The solutions to the system of equations involving quadratic function f(x) and linear function g(x) are (-1,5) and (4/3,29/3), respectively.
What is a polynomial function?A polynomial function is a relationship in which a dependent variable equals a polynomial expression. A polynomial expression is one that has numbers and variables that are raised to non-negative powers.To find the solution to the given system of equations:
A polynomial expression has the following generic form:a₀ + a₁x + a₂x² + a₃x³ + ... + aₙxⁿ.The degree of the polynomial expression has the greatest power on a variable.When degree = 2, the function is quadratic.When degree = one, the function is linear.Given quadratic equation: f(x) = 3x^2 + x + 3
We must solve the linear equation g(x). Because it is a linear equation, we utilize the two-point approach to solve it.The two point formula is: y-y₁ = ((y₂-y₁)/(x₂-x₁))*(x-x₁)
We take the points g(2) = 11, g(1) = 9
g(x) - g(1) = ((g(2)-g(1))/(2-1))*(x-1)
or, g(x) - 9 = ((11-9)/(2-1))*(x-1)
or, g(x) - 9 = 2(x-1)
or, g(x) = 2x - 2 + 9 = 2x + 7
g(x) = 2x +7, is the linear function g(x)
We are asked to solve the system of equations f(x) and g(x).
To get the solution, we must first determine what is the common solution to both f(x) and g(x).
For that, we equate f(x) and g(x).
3x² + x + 3 = 2x + 7
or, 3x² - x - 4 = 0
or, 3x² + 3x - 4x - 4 = 0
or, 3x(x+1) -4(x+1) = 0
or, (3x-4)(x+1) = 0
∴ Either 3x-4=0 ⇒ x = 4/3
or, x+1=0 ⇒ x = -1.
g(-1) = 5 (from the table)
f(-1) = 3(-1)² + (-1) + 3 = 3 - 1 + 3 = 5
g(4/3) = 2(4/3) + 7 = 8/3 + 21/3 = 29/3
f(4/3) = 3*(4/3)² + (4/3) + 3 = 16/3 + 4/3 + 9/3 = 29/3
∴ f(-1) = g(-1) and f(4/3) = g(4/3).
Therefore, the solution to the system of equations that includes quadratic function f(x) and linear function g(x) is (-1,5) and (4/3,29/3).

Hey guys please help? Trigonometry
So, the task is: find cos a, if:
1) sin a = (3√11)/10, a ∈ (0; π/2)
2) sin a = (3√11)/10, a ∈ (π/2; π)
Could someone please explain how to solve it? I can't figure out what difference a ∈ (0; π/2) and a ∈ (π/2; π) make in the way I have to solve it mmh... I'll pin my attempt to do the first one (failed for some reason)
Step-by-step explanation:
a ∈ (0; π/2) here means that our angle, a must lie between 0 and pi/2, exclusive.
So this mean our angle must be in between 0 and pi/2, but can not be neither 0 and pi/2.
Here we have
[tex] \sin( \alpha ) = \frac{3 \sqrt{11} }{10} [/tex]
We must find cos.
Using the Pythagorean theorem
[tex]( \sin( \alpha ) ) {}^{2} + ( \cos( \alpha ) ) {}^{2} = 1[/tex]
It is mostly notated as this,
[tex] \sin {}^{2} ( \alpha ) + \cos {}^{2} ( \alpha ) = 1[/tex]
But they mean the same thing, we know
[tex] \sin( \alpha ) = \frac{3 \sqrt{11} }{10} [/tex]
So we plug that in for sin a.
[tex]( \frac{3 \sqrt{11} }{10} ) {}^{2} + \cos {}^{2} ( \alpha ) = 1[/tex]
[tex] \frac{99}{100} + \cos {}^{2} ( \alpha ) = 1[/tex]
[tex] \cos {}^{2} ( \alpha ) = \frac{100}{100} - \frac{99}{100} [/tex]
[tex] \cos {}^{2} ( \alpha ) = \frac{1}{100} [/tex]
Since cos is Positve over the interval (0; π/2), we take the positive or principal square root.
[tex] \cos( \alpha ) = \frac{1}{10} [/tex]
2. We would get the same work for the second part, the only difference is that cosine is negative over the interval
(π/2, π)
So the answer for 2 is
[tex] \cos( \alpha ) = - \frac{1}{10} [/tex]
Disclaimer: Your work you did was correct, just remember for fractions like
[tex]1 - \frac{99}{100} [/tex]
Convert 1 into a fraction that has a denominator of 100.
[tex] \frac{100}{100} - \frac{99}{100} = \frac{1}{100} [/tex]
Solve the problems involving (HCF) highest common factor for each of the the following
B) A restaurant donated 540 pieces of fried chicken and 360 cups of drink for a gathering event. The restaurant has set the condition the every visitor will receive the portion of food equally. Find :
(1) Find the maximum number of visitors that can be invited to the event.
(2) Find the numbers of pieces of chicken to be received by the visitors who attended the event.
Step-by-step explanation:
the highest or greatest or largest common factor is the product of the prime factors the numbers have in common :
540 ÷ 2 = 270
270 ÷ 2 = 135
135 ÷ 2 no
135 ÷ 3 = 45
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 3 no
5 ÷ 5 = 1
540 = 2² × 3³ × 5¹
360 ÷ 2 = 180
180 ÷ 2 = 90
90 ÷ 2 = 45
45 ÷ 2 no
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 3 no
5 ÷ 5 = 1
360 = 2³ × 3² × 5¹
so, the HCF = 2² × 3² × 5¹ = 4×9×5 = 180
(1)
to satisfy the condition max. 180 visitors can be invited.
(2)
540 / 180 = 3
so, every visitor can receive 3 pieces of chicken.
and 360 / 180 = 2 cups of drink.

why might you choose to write a recursive formula rather than an explicit formula to define a sequence
a. you need to know the 54th term in the sequence
b. the sequence is neither arithmetic or geometric
c. you need to know the value of three non-sequential terms in the sequence
d. the sequence is strictly geometric
We might choose to write a recursive formula rather than an explicit formula to define a sequence because (D) the sequence is strictly geometric.
What is a sequence?A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important. It, like a set, has members (also called elements, or terms). The length of the series is defined as the number of items (which could be infinite). Unlike a set, the same components can appear numerous times in a sequence at different points, and the order does important. Formally, a sequence can be defined as a function from natural numbers (the sequence's places) to the elements at each point. The concept of a sequence can be expanded to include an indexed family, which is defined as a function from an index set that may or may not contain integers to another set of elements.Recursive formulas are commonly used to compute the nth term of a sequence, where a(n) is the sum of all the preceding values.
Using its position, explicit formulas can compute a(n).
Therefore, we might choose to write a recursive formula rather than an explicit formula to define a sequence because (D) the sequence is strictly geometric.

What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
The vertex is at the middle of the parabola, that is, a width of 80/2 = 40 meters and a height of 25 meters, hence h = 40, k = 25, and the equation is:
y = a(x - h)² + k
y = a(x - 40)² + 25
When x = 0, y = 0(start of the arc), hence the leading coefficient is found as follows:
0 = 1600a + 25
a = -25/1600
a = -1/64.

A number, h, rounded to 1 d.p. is 47.2
Another number, k, rounded to 1 d.p. is 4.8
What are the lower and upper bounds of
h - k?
The lower and upper bounds of h - k are 42.31 and 42.49 respectively.
Upper and lower bounds are the maximum and minimum values that a number could have been before it was rounded. They can also be called limits of accuracy.
The upper and lower bounds can be written using error intervals
The lowest value of h is 47.15
The greatest value of h is 47.24
The greatest value of k is 4.84
The lowest value of k is 4.75
Thus upper bound of h -k = 47.24 - 4.75 = 42.49
Thus lower bound of h -k = 47.15 - 4.84 = 42.31
Thus the lower and upper bounds of h - k are 42.31 and 42.49 respectively.

A man is 32 years older than his son. Ten years ago he was three times as old as his son was then. Find the present age of each
Answer:
Son: 26 yrs. Dad: 58 yrs.
Step-by-step explanation:
Let s equal to the present age of the son and let d equal to the present age of the dad. We can make two equations based on the information given to us. The first is about the fact that the dad is 32 yrs. older than the son:
d = s+32
the second is about the fact that 10 yrs. ago, he was triple his son's age.
d-10 = 3(s-10)
We can use the distributive property and we have:
d-10 = 3s-30
Then, let's add 10 to each side:
d = 3s-20
We can substitute the first equation into the second, resulting in:
s+32 = 3s-20
Adding 20 to both sides:
s+52 = 3s
2s = 52
s = 26
Now that we have the son's age, the dad's age is 26+32 = 58.
Son's age: 26
Dad's age: 58
The rectangles below have the same perimeter.
Rectangle:A Base=3 height=9
Rectangle B:base=4
Answer:
32 mm²
Step-by-step explanation:
perimeter of left rectangle = 2(9 mm + 3 mm) = 24 mm
length of right rectangle = L
perimeter of right rectangle = 2(L + 4 mm) = 2L + 8
perimeter of right rectangle = 24 mm
The perimeter of the right triangle is 2L + 8 and also 24, so 2L + 8 must equal 24. We can solve for L and find the length of the right rectangle.
2L + 8 = 24
2L = 16
L = 8
area of right triangle = length × width
area = 8 mm × 4 mm

Find an equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0)
The equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0) is 8x -3y = -16
Equation of a straight lineFrom the question, we are to determine the equation of the line parallel to the given equation and that passes through the given point
Lines that are parallel to each other will have the same slope.
First, we will determine the slope of the line in the given equation.
The given equation of the line is
8x − 3y = 1
Express the equation in the slope-intercept form of a line, y = mx + b
Where m is the slope and
b is the y-intercept
That is,
8x − 3y = 1
8x -1 = 3y
3y = 8x - 1
y = 8/3(x) - 1/3
By comparing,
∴ The slope of the line is 8/3
Since we are to find the equation of a line parallel to this, the slope of the line will also be 8/3
Now, find the equation of a line containing the point (-2, 0) and that has a slope of 8/3
Using the point-slope form of a line
y - y₁ = m(x - x₁)
x₁ = -2
and y₁ = 0
∴ y - 0 = 8/3(x - -2)
y = 8/3(x +2)
3y = 8(x +2)
3y = 8x + 16
8x -3y = -16
Hence, the equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0) is 8x -3y = -16

Find the distance in nm between two slits that produces the first minimum for 405-nm violet light at an angle of 57. 5°
The distance between two slits is d =2.89*10^-7 m
Distance between slits, d=2.89*10^-7 m
It is given that,
Wavelength, λ = 410nm= 410*10^-9 m
Angle, θ =45
We need to find the distance between two slits that produces first minimum. The equation for the destructive interference is given by :
dsinθ =(n+1/2) λ
For first minimum, n = 0
dsinθ =(1/2) λ
So, d is the distance between slits
d ={1/2 λ}sinθ
=2.89*10^-7 m
So, the distance between two slits is d =2.89*10^-7 m. Hence, this is the required solution.
