Determine f(x+a)−f(x) for the following function.
f(x)=x−9‾‾‾‾‾√+6
The value of the function f(x + a) - f(x) is √(x + a - 9) - √(x - 9)
How to evaluate the function value?The function definition is given as
f(x) = √(x - 9) + 6
We start by calculating the function f(x + a)
So, we have
f(x + a) = √(x + a - 9) + 6
The function definition f(x + a) - f(x) is calculated as
f(x + a) - f(x) = √(x + a - 9) + 6 - (√(x - 9) + 6)
Open the bracket
So, we have
f(x + a) - f(x) = √(x + a - 9) + 6 - √(x - 9) - 6
Evaluate the difference
So, we have
f(x + a) - f(x) = √(x + a - 9) - √(x - 9)
Hence, the value of the function f(x + a) - f(x) is √(x + a - 9) - √(x - 9)

Find all of the points of the form (x,-1) which are 3 units from the point (-6, 1).
(x, y) =
(smaller x-value)
(x, y) =
(larger x-value)
Answer:
The values of x are -6 + √5 and -6 - √5.
Step-by-step explanation:
It is given that we need to find all of the points of the form (x,-1) which are 3 units from the point (-6, 1).
Now, let us suppose that these points are in 2D coordinate system such as;
=> (x1, y1) = (-6, -1)
and let us suppose that the other point is;
=> (x2, y2) = (x, 1)
Further, the distance between both these points them is 3 units and we can write this as;
=> d = √(x1 - x2)² + (y1 - y2)²
=> 3 = √(-6 - x)² + (-1 - 1)²
After squaring both the sides;
=> 9 = 36 + x² + 12x + 4
=> 9 = x² + 12x + 40
On rearranging the equation;
=> x² + 12x + 31 = 0
Now, this is a quadratic equation of the form ax² + bx + c = 0 in which;
=> x = -b ± √(b² - 4ac) / 2a
After putting values in this for obtaining the value of x on comparing we get;
=> x = -12 ± √(12² - 4×31) / 2
=> x = -12 ± √(144 - 124) / 2
=> x = -12 ± √20 / 2
=> x = -12 ± 2√5 / 2
=> x = 2(-6 ± √5) / 2
=> x = -6 ± √5
Therefore, the values of x are -6 + √5 and -6 - √5.

Find the missing side. Round to the nearest tenth.
By using trigonometric relations, we can see that the hypotenuse of the right triangle measures 30.8 units.
How to find the missing side on the right triangle?
Here we will need to use trigonometric relations. We want to find the value of x, which is the hypotenuse of the right triangle.
We know the measure of one angle, and the adjacent cathetus to said angle, the measures are:
angle = 65°
Cathetus = 13 units.
Now we can sue the trigonometric relation:
cos(a) = (adjacent cathetus)/(hypotenuse)
Replacing what we know, we can rewrite that as:
cos(65°) = 13/x
Now we just need to solve the equation for x, we will get:
x = 13/cos(65°) = 30.8 units.
We conclude that the hypotenuse of the right triangle measures 30.8 units.

Singer A
Singer B
The number of concert shows that singer A and singer B attended will be 41 and 18 shows respectively.
How to illustrate the information?Based on the information, the equation for last year will be:
A = 2B + 5
The number will be illustrated as:
A = B + 23
Therefore, it should be noted that we will equate the expression. This will be:
2B + 5 = B + 23.
Collect like terms
2B - B = 23 - 5
B = 18.
A = 23 + B = 23 + 18 = 41

O c. Absolute difference: -492 people per square mile
Relative difference: -435.4%
O d. Absolute difference: -492 people per square mile
Relative difference: -8.1%
Answer: c
Step-by-step explanation:
The absolute difference is 492 people per square mile and Relative difference: 435.4%.
Thus, option (B) is correct.
To find the absolute difference between the two population densities, subtract the population density of country A from the population density of country B:
Absolute difference = Population density of country B - Population density of country A
= 605 people per square mile - 113 people per square mile
= 492 people per square mile
Now, the relative difference as a percentage, we use the formula:
Relative difference = (|Absolute difference| / Population density of country A) * 100
= (|492| / 113) * 100
= (492 / 113) * 100
= 4.35398230088 * 100
= 435.4%
Therefore, the absolute difference is 492 people per square mile
Relative difference: 435.4%

The solution using indices for the given equation is (x = 5/3).
What is meant by indices?The small floating quantity that makes it appear after an amount or letter is known as an index or power. Indexes is the plural of index. Indices represent the number of times a quantity or letter has indeed been multiplied on its own.Indexes are also referred to as powers or exponents. It indicates how many times a provided number must be multiplied.The multiplication of x is equal to the base x raised to a power of p.For the given expression in question;
8 × 8⁴ˣ⁻³ = 512 × 8ˣ
By the property of indices, if the base is equal; then the powers are added with sign.
8⁴ˣ⁻³⁺¹ = 512 × 8ˣ
As, we know that 512 is the cube of 8.
8⁴ˣ⁻² = 8³ × 8ˣ
Apply the power law on right side;
8⁴ˣ⁻² = 8³⁺ˣ
As, the base on both side is equal, then the exponents are also equal.
Thus,
4x - 2 = 3 + x
Bring variables and constants on different sides.
4x - x = 3 + 2

And the number of outfits Zendaya can buy is 3 .
According to the question we have been given that the
Total money Zendaya has = $540
Cost of new bicycle = $269.88
Cost of bicycle reflectors = $10.57
Cost of bike gloves = $17.76
Cost of biking outfits = $65.65
Let the number of outfits Zendaya purchases be x.
The inequality to determine the number of outfits Zendaya can purchase while staying within her budget is
