The required value of the function at f(5) = 125, as of the given conditions.
Given that,
f(x) is a polynomial of degree four with a leading coefficient 1 such that f(1) = 1, f(2) = 8 , f(3) = 27, and f(4) = 64, then the value of f(5) is ot be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
f(x) = x⁴/x
Put x = 5
f(x) = 5⁴ / 5 = 125

This year's soybean crop of 224000 t represents an increase of 40% over last year's crop. How many tons of soybeans were produced last year?
well, last year it was "x", which oddly enough is the 100%.
now, this year is 224000 tons, and that's an increase of 40%, so that's really the 100% + 40% = 140%, so if 224000 is the 140%, what's "x"?
[tex]\begin{array}{ccll} tons&\%\\ \cline{1-2} x & 100\\ 224000& 140 \end{array} \implies \cfrac{x}{224000}~~=~~\cfrac{100}{140} \implies \cfrac{ x }{ 224000 } ~~=~~ \cfrac{ 5 }{ 7 } \\\\\\ 7x=(5)(224000)\implies x=\cfrac{(5)(224000)}{7}\implies x=160000[/tex]

Answer: 63
Step-by-step explanation:
You can put this solution on YOUR website! Hi there, 2/3 = 42. Multiply 42 by 3 = 126. Divide 126 by 2 = 63. The lady's age. 63yrs old. Proof: 2/3 x 63
Answer:
63
Step-by-step explanation:
42 / 2 = 21
21 * 3 = 63
If 42 is two thirds, then one third is 21 because (2/3) / 2 = 1/3.
If 21 is one third, then the whole is 63 because (1/3) * 3 = 1.

What shape is a rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.
What is the formula for area of rectangles?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle as Area = length x width
Length of the sheep pen =80 ft
bought fencing = 180 ft
One side of rectangular sheep pen is covered with barn which is equaling the width
perimeter of rectangular sheep pen = 2(length +width)

The required value of x of a triangle is 27°.
What is a triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
Given, angle measurements of 2x, 4x+6, and x-15
Based on the definition of a triangle, the sum of all angles will be 180 degrees.
So, 2x + 4x+6 + x-15 = 180°
or, 7x - 9 = 180°
or, 7x = 189°
or, x = 189/7 = 27°
Hence, the required value of x of a triangle is 27°.

Through a given point not contained in a given line, there exists exactly one line parallel to the given line.
What are parallel lines?In Mathematics, parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and they can never meet. In Geometry, two (2) lines are parallel under the following conditions:
m₁ = m₂
Note: m represents the slope.
This ultimately implies that, two (2) lines would be parallel to each other when the slope (m₁) of the first line is equal to the slope (m₂) of the second line.
According to the Parallel postulate, there is always exactly one line that is parallel to a given line in the same plane when a point and a line are given, provided that the point is not on that line.

Which recursive sequence would produce the sequence
10,35,135,...?
Answer:
10, 35, 135, 410, 1235, ...
Step-by-step explanation:
a(1) = 10
a(n) = 3 * a(n-1) + 5
This recursive sequence starts with the initial value of a(1) = 10, and each subsequent term is calculated by applying the formula a(n) = 3 * a(n-1) + 5. The resulting sequence would be:
a(1) = 10
a(2) = 3 * a(1) + 5 = 3 * 10 + 5 = 35
a(3) = 3 * a(2) + 5 = 3 * 35 + 5 = 135
a(4) = 3 * a(3) + 5 = 3 * 135 + 5 = 410
a(5) = 3 * a(4) + 5 = 3 * 410 + 5 = 1235
And so on. This recursive sequence generates the following sequence: 10, 35, 135, 410, 1235, ...

What is slope intercept form ?The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible.
The slope intercept form of a straight line equation can be written as :
y = mx + c
Where
m = slope = (change in the y-value) axis's / (change in the value of x in the x axis)
The given line's equation is
y = - x/3 + 5
Slope = - 1/3 as compared to the slope intercept form.
The slope of one line is equal to the negative reciprocal of the slope of the other line if two lines are perpendicular.
As a result, the slope of the line through (3, 4) is 3.
In order to calculate the intercept, we would replace m with 3, x with 3 and y with 4
The equation becomes
4 = 3 × 3 + c
c = -5
putting the value of c and m in the slope intercept form equation
We get
y = 3x - 5

Answer:
A.) y = –3x + 4 and y = –3x – 4
Step-by-step explanation:
The first equation of a system of equations is y = -3x + 4 and the second equation is y = -3x - 4.
We can see that both equations have the same slope of -3 and have different y-intercepts of 4 and -4, respectively.
Because the two lines are parallel, they will never intersect and will overlap each other, resulting in an infinite number of solutions.
Therefore, the system of equations y = –3x + 4 and y = –3x – 4 has infinitely many solutions.
