The non-real solutions are (2 + i√26)/3 and (2 - i√26)/3
How to determine the non-real solutions?The equation of the polynomial expression is given as:
3x^3 + 14x^2 - 14x + 60 = 0
From the question, we have
x = -6
This gives
So, we have
x + 6 = 0
The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0
This is represented as
3x^3 + 14x^2 - 14x + 60/x + 6
Using a graphing calculator, we have
3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10
Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula
So, we have
x = (-b ± √(b² - 4ac))/2a
This gives
x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3
So, we have
x = (4 ± √-104)/6
This gives
x = (4 ± 2√-26)/6
Divide
x = (2 ± √-26)/3
Rewrite as
x = (2 ± i√26)/3
Split
x = (2 + i√26)/3 and x = (2 - i√26)/3
Hence, the non-real solutions of the polynomial expression are x = (2 + i√26)/3 and x = (2 - i√26)/3

determine whether the side lengths form a right triangle just say yes or no
Answer:
Yes, the side lengths
Explanation:
To be able to determine if the given side lengths of the triangle will form a right triangle, we'll have to apply the Pythagorean Theorem which states, in a right-angled triangle, the square of the hypotenuse(the longest side) must be equal to the sum of squares of the other two sides.
So let's go ahead and confirm;
[tex]\begin{gathered} 14.5^2=10.5^2+10^2 \\ 210.25=110.25+100 \\ 210.25=210.25 \end{gathered}[/tex]Since the Pythagorean theorem is obeyed as we can see above, then the side lengths will form a right triangle.
What are the next numbers on the ratios chart
The equivalent ratios are 14:56 and 5 : 20 .
A ratio in mathematics shows how many times one number appears in another. For instance, if there were eight oranges and six lemons on a fruit platter, the ratio of oranges to lemons would be eight to six.
By dividing each quantity by the sum of all the numbers' common components, ratios can be reduced (much like fractions are). The fraction is said to be in its simplest form when the ratio's numbers are the tiniest practical integers.
A and B are frequent names for the ratio's antecedent and consequent, respectively.
The given ratios are 2 : 8 and 7 : 28 . which when simplified given the ratio 1 : 4 .
Now we know that 1 / 4 = k which is the common ratio.
Hence 14 / x = k = 1 / 4
or , x = 56
Again 5 / y = k = 1 / 4
or , y = 20
Therefore the equivalent ratios are 14:56 and 5 : 20 .

Jeremy and Justine work for a company that receives $45 for each unit of output sold. The company has a variable cost of $25 per item and a fixed cost of $1600.
Based on this information, Jeremy and Justine make some projections about potential profit.
Jeremy states that for every 100 units of output sold, the company will make $3,600 in profit.
Justine states that for every 300 units of output sold, the company will make $4,400 in profit.
Part A
Determine a function that models the profit for the company based upon the conditions for revenue and expense.
Part B
Are the claims about profit that Jeremy and Justine made true? Explain why Jeremy and Justine are each correct or incorrect and justify your reasoning.
The function for profit given the conditions for revenue and expense is P = $20a - $1,600.
The first claim is incorrect because profit is $400
The first claim is incorrect because profit is $4,400.
What is the profit?Profit is revenue less total cost. Total cost consists of fixed cost and variable cost. Fixed cost is the cost that does not change with the level of output. Variable cost is the cost that changes with output. It increases as the level of output increases. Revenue is output multiplied by price per unit.
Profit = revenue - total cost cost
Profit = (price x output) - fixed cost - variable cost
P = ($45 x a) - $1,600 - ($25 x a)
P = $45a - $1,600 - $25a
P = $20a - $1,600
Where:
P = profit
a = output
Profit when 100 units is sold:
P = (20 x 100) - $1,600
$2,000 - $1,600 = $400
Profit when 300 units are sold
P = (300 x 20) - $1600
$6,000 - $1,600 = $4,400

Answer:
522 1/2 revolutions
Step-by-step explanation:
First convert 13 3/4 into improper fraction
13 3/4 = (13 x 4 + 3)/4 = 55/4
Since these many revolutions are made in 1 minute, to find total number of revolutions made in 38 minutes, simply multiply 55/4 x 38
==> 55/4 x 38 = (55 x 38)/4 = 2090/4
Divide by 2 both numerator and denominator
==> (2090 ÷ 2)/(4 ÷ 2) = 1045/2 = 522 1/2

Suppose that the functions h and g are defined as follows.

g(x) = 4x+5
h
¹(²)(-1).
(a) Find
h
(b) Find all values that are NOT in the domain of
g
If there is more than one value, separate them with commas.
For the given functions, we have that:
a) The numeric value of the division function at x = 4 is of (h/g)(4) = 81/21 = 3.86.
b) The value that is not in the domain of the division function is of x = -1.25.
Division functionIn this problem, the functions that we are given are defined as follows:
h(x) = (x + 5)(x + 5).g(x) = 4x + 5.To find the quotient function of h(x) and g(x), we just divide the function h(x) by the function g(x), that is:
h(x)/g(x) = [(x + 5)(x + 5)]/(4x + 5).
At x = 4, the numeric value is found replacing each instante of x by 4, hence:
(h/g)(4) = [(4 + 5)(4 + 5)]/(4(4) + 5)) = 81/21 = 3.86.
The denominator of a fraction cannot be zero, as division by zero does not exist, hence the value of x that is not on the domain of the division function is found as follows:
4x + 5 = 0.
4x = -5.
x = -5/4
x = -1.25.

Given (0, 0) is a data point and 72/6 = 144/12 = 216/18 = 12
Therefore; Yes it is proportional because the ratio for Dollar per hour are all equivalent to 12 dollar per hour
Question 2;
The points on the graph are;
(0, 0), (5, 700), (6, 840), (7, 980)
Therefore;
y = (5/700)•x = (1/140)•x
The table is therefore;
x; 1, 2, 3, 4
y; 140 280 420 560
Question 3;
The ratio of the dozens of cookies to cups of flour, gives;
Recipe 1; R = 2/1.5 dozen per cup of flour
Which gives;
Approximately 1.33 dozens per cup of flour
Recipe 2, R = 3/3 dozens per cup of flour
Which gives;
Recipe 3, R = 4/4.5 dozens per cup of flour
Therefore;
No it is not proportional because the ratios between the number of cookies and the cups of flour are not all equivalent
Question 4
The ratio of the terms are;
18.26/36.5 = 11.6/23.2 = 1/2 ≠ 21.1/63.3 = 1/3
Therefore;
No it is not proportional because 18.26/36.5 is not equal 21.1/63.3
Question 5
Given that the graph is a straight line that passes through the origin, it is a proportional relationship with which gives;
Yes, it is a proportional relationship because, it is a line that intersects with the origin
Question 6
The number of calories burned is dependent on the number of hours worked out. For a one–hour work out 190 calories are burnt, and for a two–hours work out there are 380 calories burned
Question 7
The relationship is proportional, given that 3.5/2 = 8.75/5 = 12 .25/7 = 1.75
Therefore; Yes, because the ratios for miles per hour, are all equivalent to 1.75

Use the graph to evaluate the expressions below.
f(2) = 3
f⁻¹(2) = 1
f⁻¹(0) = -1
(f⁻¹o f)(1) = 1
The graph of f(x) is given. Here, f(x) = y and f⁻¹(y) = x.
That is, f(x) are y values corresponding to the given x-values and f⁻¹(y) is the x-value corresponding to the given y-value.
From the graph, f(2) is the y value when x = 2.
So, f(2) = 3
Now f⁻¹(2) is the x-value when y = 2.
So, f⁻¹(2) = 1
Also f⁻¹(0) =-1
Since f(1) = 2,
(f⁻¹o f)(1) = f⁻¹(f(1)) = f⁻¹(2) = 1

What type of linear equation is X +1 equals X +1?
It depicts horizontal linear equation, as the slope is 0.
The slope of horizontal lines is zero. Consequently, m = 0 in the slope-intercept equation y = mx + b. Y = b, where b is the y-coordinate of the y-intercept, results in the equation.
The y-coordinate of every point on a horizontal line is the same. The line's equation is y=b if two points share the same y coordinate, b. The point (0,b) is the y-intercept of the horizontal line y=b. Horizontal lines don't have an x -intercept other than the line y=0.
A horizontal line is a line that is perpendicular to the x-axis. Because the value of x never changes, the graph of a relation of the form x = 5 is a line parallel to the y-axis.

Dean biked 88 kilometers on Thursday and 5.7 kilometers on Friday. How far did Dean bike in all on Thursday and Friday?
Dean's bike moved a total distance of 93.7 kilometers on Thursday and Friday
How to determine the total distance moved by Dean bike altogether on Thursday and Friday?From the question, we have the following parameters:
Thursday = 88 kilometers
Friday = 5.7 kilometers
The total distance moved by Dean bike altogether on Thursday and Friday is the sum of the distance moved on Thursday and on Friday
Substitute the known values in the above equation
So, we have
Total distance = Distance moved on Thursday + Distance moved on Friday
Substitute the known values in the above equation
So, we have
Total distance = 88 kilometers + 5.7 kilometers
Evaluate the sum
So, we have
Total distance = 93.7 kilometers
Hence, the total distance moved by the bike is 93.7 kilometers
