¿Para qué valor de la constante "b" la función real
f(x) = 2bx³ + 2x² − 3 tiene un extremo relativo en x = -1/6
a) b=4
b) b=-4
c) c=-6
d) b=6
e) b=-3
Answers
La función dada es f(x) = 2bx³ + 2x² - 3.
Primero, calculemos la derivada de la función:
f'(x) = 6bx² + 4x
Ahora evaluemos la derivada en x = -1/6:
f'(-1/6) = 6b(-1/6)² + 4(-1/6)
= b/6 - 2/6
= (b - 2)/6
Para que haya un extremo relativo en x = -1/6, la derivada debe ser igual a cero en ese punto, es decir:
(b - 2)/6 = 0
Despejando la ecuación, tenemos:
b - 2 = 0
b = 2
Por lo tanto, el valor de la constante "b" que produce un extremo relativo en x = -1/6 es b = 2.
Ninguna de las opciones proporcionadas (a, b, c, d, e) coincide con el resultado obtenido.
Dakota measured a neighborhood park and made a scale drawing. The scale of the drawing was 1 inch : 5 yards. A soccer field in the park is 12 inches wide in the drawing. How wide is the actual field?
Answers
The actual width of the soccer field is 60 yards.
Given, the scale of the drawing is 1 inch : 5 yards.
The width of the soccer field in the drawing is 12 inches.
So, the actual width of the soccer field can be found by multiplying the width in the drawing by the scale factor:
Actual width = Width in drawing x Scale factor
The scale factor is 5 yards per inch, so we can write:
Actual width = 12 inches x 5 yards per inch
Actual width = 60 yards
Therefore, the actual width of the soccer field is 60 yards.

Which of the following function pairs are inverses?
Question 3 options:
A)
B)
C)
f (x) = x2 – 16 and g(x) = x – 4
D)
Answers
The function pairs that are inverses are:
C) f(x) = 5x - 3 and g(x) = (x + 3)/5
To determine if two functions are inverses, we need to check if applying one function and then the other function will return the original input.
Let's go through each option:
A) f(x) = -2x and g(x) = (1/2)x
To check if they are inverses, we can apply function f(g(x)) and see if it returns x:
f(g(x)) = f((1/2)x) = -2(1/2)x = -x
Since f(g(x)) = -x ≠ x, these functions are not inverses.
B) f(x) = 4x² and g(x) = √x
To check if they are inverses, we can apply function f(g(x)) and see if it returns x:
f(g(x)) = f(√x) = 4(√x)² = 4x
Since f(g(x)) = 4x = x, these functions are not inverses.
C) f(x) = 5x - 3 and g(x) = (x + 3)/5
To check if they are inverses, we can apply function f(g(x)) and see if it returns x:
f(g(x)) = f((x + 3)/5) = 5((x + 3)/5) - 3 = x + 3 - 3 = x
Since f(g(x)) = x, these functions are inverses.
D) f(x) = x² - 16 and g(x) = x - 4
To check if they are inverses, we can apply function f(g(x)) and see if it returns x:
f(g(x)) = f(x - 4) = (x - 4)² - 16 = x² - 8x + 16 - 16 = x² - 8x
Since f(g(x)) = x² - 8x ≠ x, these functions are not inverses.
Based on the analysis above, the function pairs that are inverses are:
C) f(x) = 5x - 3 and g(x) = (x + 3)/5

What are the zeros of the function defined by y = x2 + 6x + 5?
Answers
Setting y = 0, the equation becomes:
0 = x^2 + 6x + 5
To solve this quadratic equation, we can factor it or use the quadratic formula. In this case, let's use the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions for x are given by:
x = (-b ± √(b^2 - 4ac)) / (2a)
For our equation, a = 1, b = 6, and c = 5. Substituting these values into the quadratic formula, we have:
x = (-(6) ± √((6)^2 - 4(1)(5))) / (2(1))
Simplifying further:
x = (-6 ± √(36 - 20)) / 2
x = (-6 ± √16) / 2
x = (-6 ± 4) / 2
This gives us two possible solutions:
x = (-6 + 4) / 2 = -1
x = (-6 - 4) / 2 = -5
Therefore, the zeros of the function y = x^2 + 6x + 5 are x = -1 and x = -5.

4.1 Find the intervals on which the function = [tex]x^{3}[/tex] −
4[tex]x^{2}[/tex]$ + 10 is increasing or decreasing.
Answers
The intervals on f(x) is increasing on (-∞, 0) and (8/3, ∞), and decreasing on (0, 8/3).
The intervals on which the function f(x) = x³ − 4x² + 10 is increasing or decreasing need to find its derivative and determine its sign.
f(x) = x³ − 4x² + 10
f'(x) = 3x² − 8x
The critical points we set f'(x) = 0 and solve for x:
3x² − 8x = 0
x(3x − 8) = 0
x = 0 or x = 8/3
These are the critical points of the function.
Now we can determine the sign of f'(x) in each interval:
Interval (-∞, 0):
Choose x = -1. f'(-1)
= 3(-1)² - 8(-1)
= 11 is positive.
So f(x) is increasing on (-∞, 0).
Interval (0, 8/3):
Choose x = 1. f'(1) = 3(1)² - 8(1)
= -5 is negative.
So f(x) is decreasing on (0, 8/3).
Interval (8/3, ∞):
Choose x = 3. f'(3) = 3(3)² - 8(3)
= 19 is positive.
So f(x) is increasing on (8/3, ∞).

Answers
The measure of the angles is c = 37. 5 degrees
d = 15 + 37.5 = 52. 5 degrees
How to determine the anglesTo determine the value, we need to know what complementary angles are;
Complementary angles are defined as pair of angles whose sum is equal to 90 degrees
From the information given, we have that;
Angle c and d are both complementary angles
Also, the measure of angle d is 15 degrees greater than the measure of angle c
Then, we have;
d = 15 + c
Substitute the values
c + 15 +c = 90
collect like terms
2c = 90 - 15
2c = 75
Divide both sides by the coefficient
c = 37. 5 degrees

The graph of g(x) will have the same shape as f(x), but every y-coordinate will be increased by 4 units,The graph of h(x) will have the same shape as f(x), but every x-coordinate will be decreased by 1 unit,The graph of k(x) is 20 and every y-coordinate is increased by 10 units and the graph of m(x) is horizontally squeezed.
To describe the graphs of the given functions, let's first analyze the effects of the transformations applied to the original function f(x) = 5 sin(x).
1. g(x) = 5 sin(x) + 4:
The function g(x) is obtained by vertically shifting the graph of f(x) by 4 units upward. This means that the graph of g(x) will have the same shape as f(x), but every y-coordinate will be increased by 4 units.
2. h(x) = 5 sin(x + 1):
The function h(x) is obtained by horizontally shifting the graph of f(x) to the left by 1 unit. This means that the graph of h(x) will have the same shape as f(x), but every x-coordinate will be decreased by 1 unit. The period of the function remains the same.
3. k(x) = 20 sin(x) + 10:
The function k(x) is obtained by vertically stretching the graph of f(x) by a factor of 20 and then shifting it 10 units upward. This means that the amplitude of the graph of k(x) is 20 (compared to the amplitude of 5 in f(x)), and every y-coordinate is increased by 10 units.
4. m(x) = 5 sin(4x - 1):
The function m(x) is obtained by compressing the graph of f(x) horizontally by a factor of 4, reflecting it across the y-axis, and shifting it 1 unit to the right. This means that the period of m(x) is 1/4 of the period of f(x), and the graph is horizontally squeezed. The reflection across the y-axis means that the graph of m(x) will be inverted compared to f(x). The amplitude remains the same.
Remember that the graph of the original function f(x) = 5 sin(x) represents a sine wave with an amplitude of 5 and a period of 2π. Applying the transformations described above will modify the position, scale, and shape of the graph, resulting in the respective graphs for each function g(x), h(x), k(x), and m(x).

First, let's find the equation of line A using the two given points:
Calculate the slope (m) of line A:
m = (y2 - y1) / (x2 - x1)
m = (6 - 2) / (1 - (-1))
m = 4 / 2
m = 2
Use the point-slope form of a line to write the equation of line A:
y - y1 = m(x - x1)
Taking (-1, 2) as a point on line A:
y - 2 = 2(x - (-1))
y - 2 = 2(x + 1)
y - 2 = 2x + 2
y = 2x + 4
Now we need to find the point where line A (y = 2x + 4) crosses line B (y - x).
Substitute y = 2x + 4 into the equation y - x:
2x + 4 - x = 0
x + 4 = 0
x = -4
Substitute the value of x into the equation of line A to find the corresponding y-coordinate:
y = 2x + 4
y = 2(-4) + 4
y = -8 + 4
y = -4
Therefore, the coordinates of the point where line A crosses line B are (-4, -4).

Profit = Selling price - Cost price
Profit = #540,000 - #450,000
Profit = #90,000
To find the profit as a percentage of the cost price, we divide the profit by the cost price and then multiply by 100.
Profit percentage = (Profit / Cost price) x 100
Profit percentage = (#90,000 / #450,000) x 100
Profit percentage = 20%
