Knowing that they are traveling 60 miles per hour, 60h is equivalent to how many miles they are traveling. When adding 300 you know that would be the a1 term going along the rules of sequences.
Therefore 60h is the rate of increase.
300 is the miles traveled on the first day.
With this information in mind we can now answer the True and false statements.
1. 5 represents the hours they drove on the first day, therefore 1 is a false statement.
2. 60 represents the mph they are traveling on the second day, therefore 2 is a false statement.
3. 300 represents the miles they traveled on the first day, therefore 3 is a true statement.

What is the Commutative Property?The commutative property is associated with mathematical operations such as addition and multiplication. It indicates that switching the order or location of two integers while adding or multiplying them has no effect on the outcome. For example, 4 + 5 gives 9, and 5 + 4 also gives 9.
The expression is given in the question below as
p⁶ + (q + 8)
We have to determine the expression equivalent to the given expression.
As per the given question, we have
⇒ p⁶ + (q + 8)
Using the commutative property of addition, we get

For a certain company, the cost function for producing x items is C(x)=50x+100 and the revenue function for selling x items is R(x)=−0.5(x−90)2+4,050 . The maximum capacity of the company is 150 items.
Assuming that the company sells all that it produces, what is the profit function?
P(x)=
What is the domain of P(x) ?
The company can choose to produce either 40 or 50 items. What is their profit for each case, and which level of production should they choose?
Profit when producing 40 items =
Profit when producing 50 items =
Can you explain, from our model, why the company makes less profit when producing 10 more units?
The profit function is P(x) = −0.5x² + 40x - 100
The domain is 3 < x < 75Profit when producing 40 items = 700Profit when producing 50 items = 650The company makes less profit when they produce moreHow to determine the profit function?From the question, we have the following equations that can be used in our computation:
Cost function, C(x) = 50x + 100
Revenue function, R(x) = −0.5(x − 90)² + 4050
The profit function is the difference between the revenue and the cost
So, we have
P(x) = R(x) -CP(x)
Substitute the known values in the above equation, so, we have the following representation
P(x) = −0.5(x − 90)² + 4050 - 50x - 100
Evaluate the like terms
P(x) = −0.5(x − 90)² - 50x + 3950
Expand
P(x) = −0.5(x² − 180x + 8100) - 50x + 3950
Expand
P(x) = −0.5x² + 90x - 4050 - 50x + 3950
Evaluate the like terms
P(x) = −0.5x² + 40x - 100
The domain of the functionIn (a), we have
P(x) = −0.5x² + 40x - 100
Using a graphing calculator, the reasonable domain is
3 < x < 75
So, the domain is 3 < x < 75
The profit at each productHere, we have
x = 40 or 50
So, we have
P(40) = -0.5(40)² + 40(40) - 100 = 700
P(50) = -0.5(50)² + 40(50) - 100 = 650
Why the profit makes less profitIn (d), we have
P(40) = 700
P(50) = 650
This means that the profit reduces as they produce more

The function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x
Transformation techniques
Transformation is the process of changing the position of an object on the xy-plane.
Given the parent function
f(x) = 4x
If the function is not reflected over x-axis, the resulting function will be f(x) = -4x
If the resulting function is compressed by a factors of 1/8, hence the final function rule will be;
g(x) = 1/8(-4x)
g(x) = -1/2x
Hence the function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

The base of a triangle is twelve more than twice its height. If the area of the triangle is 50 square centimeters, find its base and height.
The height of the triangle is 4.68 cm and base of the triangle is 21.36 cm.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
Base of triangle is twelve more than twice its height.
Also, area of triangle = 50 square centimeters.
Let height of the triangle is x cm,
Therefore, the base of triangle will be 2x+12 cm.
The area of triangle = 50
1/2 × (2x+12) × x = 50
x (x+6) = 50
x² + 6x -50 = 0
By solving the equation,
x = -3 + √59 and -3 - √59
Length can not be negative,
Therefore, x = -3 + √59 or x = 4.68114

you convert the 80% to decimal form so its now 0.80.
then you multiply how long the school play was (90) times the 'percentage' of how long the main character was on the stage (0.80).

Write and solve the equation that represents the sentence below.
The product of 18 and a number is 109.8 .
Which statements are correct? Select three options.
The linear equation we want to write is:
18*x = 109
And the solution is x = 6.06
How to write and solve the equation?Remember that the product between two numbers is just a multiplication A*B.
Here we know that the product of 18 and a number, is 109.
If we define the variable x as the number, then we can write the linear equation:
18*x = 109
Where the product between 18 and x is equal to the number 109.
Now, we want to find the value of x, to do that, we need to divide both sides of the equation by 18, then we will get:
18*x/18 = 109/18
x = 109/18 = 6.06
The solution of the linear equation is 6.06

A card is chosen at random from a standard
deck. What is the probability that the card is
a spade or a king, given that it is black?
the probability of getting a king or a spade is 30.7%.
What is probability?
Simply put, probability measures how probable something is to occur. The probability formula can be used to calculate the likelihood of an event by simply dividing the favorable number of possibilities by the total number of options. The likelihood of an occurrence might vary from 0 to 1 because the favourable number of outcomes can never be greater than all possible outcomes.
The formula for calculating the probability of an event is
Probability of an event = Favorable outcomes/Total number of outcomes.
Favorable outcomes = 16 {13 spade cards which include one king and the remaining 3 king cards.}
The total number of outcomes = 52.
Probability of choosing a king or a spade= 16/52 = 8/26 = 4/13=0.307
Hence, the probability of getting a king or a spade is 30.7%.

The other roots of the cubic equation p(x) = 24·x³ - 46·x³ + 29·x - 6 are;
x = 1/2
x = 3/4
What is a cubic equation in mathematics?A cubic equation is an equation that has 3 as the highest index.
The specified polynomial in the question is presented as follows;
P(x) = 24·x³ - 46·x² + 29·x - 6
The solution of the equation is; x = (2/3)
Therefore, (x - 2/3) is a factor of the equation and we get;
(24·x³ - 46·x² + 29·x - 6) ÷ (x - 2/3) has a remainder of 0
Dividing the above expression using long division, we get;

The other real roots of the specified equation can be found as follows;
The equation for the roots is; P(x) = 24·x³ - 46·x² + 29·x - 6 = 0
From the above long division, therefore;
24·x³ - 46·x² + 29·x - 6 = (24·x² - 30·x + 9) × (x - 2/3) = 0
Which indicates; (24·x² - 30·x + 9) = 0 or (x - 2/3) = 0
The other solution are;
24·x³ - 30·x + 9 = 0
3·(·8·x² - 10·x + 3) = 0
8·x² - 10·x + 3 = 0
Solutions for the above equation in the form; a·x² + b·x + c = 0 can be obtained using the quadratic formula as follows;
The quadratic formula; x = [tex]\dfrac{-b\pm\sqrt{b^2 - 4\cdot a\cdot c} }{2\cdot a}[/tex]
By comparing the equation, 8·x² - 10·x + 3 = 0 to the equation, a·x² + b·x + c = 0, we get;
a = 8, b = -10, and c = 3
Therefore;
x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8)
((-10)² - 4 × 8 ×3) = 2
Therefore;
x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8) = (10 ± 2)/(16)
x = 3/4, and x = 1/2
Therefore, the other other roots in increasing sequence are;
