The ordered pairs are on the inverse function are (-5, -2) and (4, 1)
What are inverse functions?Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function
How to determine the ordered pairs on the inverse of the function?From the question, we have the following coordinate points
Point (negative 2, negative 5)Inflection point (0, 1)Curves up through (1, 4)Rewrite the points as:
Point (-2, -5)Inflection point (0, 1)Curves up through (1, 4)Remove the inflection point.
So, we have
Point (-2, -5)Curves up through (1, 4)The next step is to switch/swap the positions of x and y in the above equation ordered pairs
So, the points become:
Inverse point (-5, -2)Another inverse point (4, 1)Hence, the ordered pairs that are on the inverse function of the function are (-5, -2) and (4, 1)

What is an equation in slope-intercept form for the line
perpendicular to y = 3x + 9 that
contains (-6, 3)?
An equation in slope-intercept form for the line perpendicular to y = 3x + 9 that contains (-6, 3) is 3 = -1/3(-6) + 1.
What is slope-intercept form?The most "popular" type of a straight line is one with a slope-intercept. Due to its simplicity, this is helpful to a lot of students. The slope and y-intercept of the straight line can be easily determined or read off from this form, making it possible to describe its properties without having access to the graph.
The equation for a line written in slope-intercept form
y = mx + b
Where,
m is the slope, and b is the y-intercept.
We know that the slope of a line perpendicular to given equation becomes reciprocal with opposite sign.
So, here slope is 3 and in perpendicular line it will become -1/3.
Now we will go with slope-intercept form and put the values (-6, 3) as x and y in y = mx + b
⇒ 3 = -1/3(-6) + b
Lets solve for b
⇒ b = 3 - ( -1/3(-6))
= 3 - (2)
= 1
Now we have the desired equation
3 = -1/3(-6) + 1
Thus, An equation in slope-intercept form for the line perpendicular to y = 3x + 9 that contains (-6, 3) is 3 = -1/3(-6) + 1.

In order to determine which person is the first to win both prizes, you have to find the least common multiple to both numbers 14 and 10.
To determine what is the least common multiple number you proceed as follow:
You list different multiples of each number 14 and 10.
For 14: 14 28 42 56 70 84 98 112
For 10: 10 20 30 40 50 60 70 80
The least common multiple is 70, becasue is the first common number in each list.
Hence the 70th person in the line will win both prizes.
If a ball is thrown directly upward with a velocity of 88 ft/s, its height (in feet) after t seconds is
given by y = 88t - 16t².
When does the ball reach its maximum height? (Round to two decimal places)
If a ball is thrown directly upward with a velocity of 88 ft/s, its height (in feet) after t seconds is given by y = 88t - 16t².The ball will reach its maximum height at 121 feet.
Maximum heightGiven equation:
y = 88t - 16t²
Maximum height dy/dt = 0
88-32t = 0
32t = 88
t = 88/32sec
t = 2.75sec
Hence,
Maximum height attained by the ball :
Maximum height attained by the ball = 88(2.75)-16(2.75)²
Maximum height attained by the ball = 242 - 121
Maximum height attained by the ball = 121 feet
Therefore the maximum height is 121 feet.

The value of the expression given as 3 - √x⁵ is 3 - x^2√x
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to evaluate the expression?The expression is given as
3 - √x⁵
Express 5 as the sum of 4 and 1
So, we have the following equation
3 - √x⁵ = 3 - √x^(4 + 1)
Apply the law of indices to expand the equation
So, we have the following equation
3 - √x⁵ = 3 - √(x^4 * x)
Next, we expand the equation
So, we have the following equation
3 - √x⁵ = 3 - √x^4 * √x
Evaluate the square root of x^4
So, we have the following equation
3 - √x⁵ = 3 - x^2 * √x
Evaluate the product

The sum of the first 7 terms for the geometric sequence with first term 3, seventh term 46,875, and common ratio 5 is 58,583.
A geometric progression is a sequence where each and every succeeding term is formed by multiplying the preceding term by a constant number. That constant number is called common ratio.
The common ratio is provided to be 5. While the first term is 3.
The seventh term is 46875.
The formula for sum of n terms of a GP is,
Sn = a(rⁿ-1)/(r-1)
We have to find sum of seven terms,
Sn = a(r⁶.r - 1)/(r-1)
Putting,
a = 3
r = 5
n =6
Sn = 3(5⁶.5 - 1)/(5-1)
Sn = (3.5⁶.5 - 3)/4
Sn = (46875×5 - 3)/4

The score required for the exam so that the score is higher than 30.85% is 412 for certain standardized test.
What is defined as the z-score?A Z-Score is a measurable statistic of a score's connection to the mean among a set of scores.A Z-score can tell a trader whether a value is characteristic for a given data set or atypical.In overall, a Z-score of less than 1.8 indicates that a company may be on the verge of bankruptcy, whereas a score nearer to 3 indicates that a company is in good financial standing.The formula for finding the z-score is;
z = (x - μ)/σ
x = sample size
μ = mean of the population
σ = standard deviation of the population.
The given values are-
μ = 421
σ = 18
Probability = 30.85% = 0.3085
Check the z-score from the negative z table for 0.3085
z score = -0.5
Put the values in z formula and find x.
z = (x - μ)/σ
-0.5 = (x - 421)/18

find all real and complex zeros for f(x)=x^3-x^2+3x-3
The real and complex zeros for the function given as .f(x) = x³ - x² + 3x - 3 are x = 1 and x = ±i√3, respectively
How to determine the zeros of the function?The equation of the function is given as
f(x) = x³ - x² + 3x - 3
Group the terms of the function in two's
So, we have the equation
f(x) = (x³ - x²) + (3x - 3)
Factor each group in the function
f(x) = x²(x - 1) + 3(x - 1)
Factor out x - 1
f(x) = (x² + 3)(x - 1)
Set to 0
(x² + 3)(x - 1) = 0
This gives
x² = - 3 and x = 1
Evaluate the roots
x = ±i√3 and x = 1

C: 10.5x<26
D: 10.5x>26
Answer:
B
Step-by-step explanation:
it is simple.
because AB > AD, their size representations must have the same relationship.
therefore,
9x - 16 > 1.5x + 42
that could be simplified to
7.5x > 58
The inequality that represents AB > AD is B: 9x - 16 > 1.5x + 42.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.

Classify the following functions as growth or decay: f(x) = 10 (6/7)^x, g(x)= 1/3e^x, h(x)=5e^-x, k(x)= -10(6/7)^x
It is known that any exponential function with the form f(x)=a^x is an increasing function while a function of the form g(x)=a^(-x) is a decreasing function.
Furthermore, it a function h(x) is increasing, then the function -h(x) is decreasing. By analogy, if a function k(x) is decreasing, then -k(x) is increasing.
Now let's analyze the functions from the problem.
[tex]\text{ Let }f(x)=10\cdot(\frac{6}{7})^x[/tex]Since (6/7)^x is increasing and the multiplying factor of 10 is positive, then the function f(x) is also increasing.
