Which equation is the inverse of y = 16x2 + 1?
y = plus-or-minus StartRoot StartFraction x Over 16 EndFraction minus 1 EndRoot
y = StartFraction plus-or-minus StartRoot x minus 1 EndRoot Over 16 EndFraction
y = StartFraction plus-or-minus StartRoot x EndRoot Over 4 EndFraction minus one-fourth
The inverse of the given function, y = 16x² + 1 is: B. y = ±√(x - 1)/16
What is an inverse function?In Mathematics, an inverse function can be defined as a type of function that is obtained by reversing (undoing) the operation of a given function (f(x)).
Generally speaking, a given function (f(x)) and its inverse function has the following property f⁻¹(f(x)) = x.
In order to determine the inverse of the given function, we would interchange input value (x) and the output value (y) as follows:
y = 16x² + 1
x = 16y² + 1
Subtracting 1 from both sides, we have:
16y² + 1 - 1 = x - 1
16y² = x - 1
Dividing both sides by 16, we have:
y² = (x - 1)/16
Taking the square root of both sides, we have:
y = ±√(x - 1)/16

Order the following expressions from least to greatest.
Answer:
[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]
Step-by-step explanation:
The bars either side of an expression or a value are the absolute value symbol. "Absolute value" means how far a number is from zero. Therefore, the absolute value of a number is its positive numerical value.
The values of a, b and c are negative. All expressions except "a" are absolute values, and are therefore positive numerical values. Therefore, "a" is the least expression.
The simplest way to calculate each expression's numerical value is by assigning approximate numbers to each value, then carrying out each calculation.
From inspection of the graph:
a ≈ -3.8b ≈ -1.3c ≈ -0.7[tex]\begin{aligned} \implies |a - b| & \approx |-3.8 - (-1.3)|\\ & = |-2.5| \\ &= 2.5\end{aligned}[/tex]
[tex]\begin{aligned} \implies |b - c| &\approx |-1.3 - (-0.7)| \\ &= |-0.6| \\ &= 0.6\end{aligned}[/tex]
[tex]\implies a \approx -3.8[/tex]
[tex]\begin{aligned} \implies |a - c| &\approx |-3.8 - (-0.7)| \\ &= |-3.1| \\ &= 3.1\end{aligned}[/tex]
Therefore: -3.8 < 0.6 < 2.5 < 3.1
Hence, the expressions from least to greatest are:
[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]
Tom sold t-shirts and hats at a festival. He made a $5 profit for each t-shirt he sold. He also made a profit of $40 from selling hats. If he made a total profit of $125, how many t-shirts did he sell?
The total number of t-shirts sold by Tom equals to 17 t-shirt.
What is a profit?Basically, a profit refers to the difference between the revenue that an entity has received from its outputs and the opportunity costs of its inputs.
We need to note that he made a total profit of $125. From here, we will proceed to use that data to solve other sections.
From the total profit of $125, he also made a profit of $40 from selling hats. That means that the T-shirt sales alone gives him a profit of $85 ($125 - $40).
Total quantity of t-shirt sold is computed as follows:
= Total profit from t-shirt / Profit per shirt
= $85 / $5
= 17 t-shirt

What is the image of the point (-5,-7) after a rotation of 270° counterclockwise about the origin?
Answer:
7, -5
Step-by-step explanation:
-5, -7 after a rotation of 270 degrees lands in quadrant 2 left y positive where x negative. while 90 degree clockwise is equal to 270 degree counterclockwise = 7 ,-5 What are the coordinates of the image after a rotation of 90 clockwise?
When the point is rotated through 90° clockwise about the origin, the point M (h, k) takes the image M’ (k, -h). Therefore, the new position of point M (-2, 3) will become M’ (3, 2).
How do you calculate a 90 degree rotation?
The rule for a rotation by 90° about the origin is (x,y)→(−y,x) .
What is the image of point 3/5 If the rotation is?
Answer: The image point will be (-3, -5) .
How do you find the coordinates of the image of a point after a 270 degree rotation?
Answer – To find the coordinates of point (x,y) after a 270° counterclockwise rotation about the origin, multiply the x-coordinate by -1 and then interchange the x- and y-coordinates.
How do you find the rotation point?
The x coordinate of the rotated point is rcos(θ), and the y coordinate is rsin(θ). If you plug in 5 and 66.87 for r and θ, you find that the rotated point (x1,y1) = (1.964, 4.598).
What is 270 degrees rotated?
270 Degree Rotation When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.
What is 90 degrees counterclockwise?
90 Degree Rotation When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.
How do you rotate a point 90 degrees clockwise?

Let f'(x) = xIn(2x). Determine a simplified expression for the rate of change of f'(x)
The simplified expression for the rate of change of f'(x) is x²(2 ln(2x) - 1)/4 + c.
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
It is given that:
f'(x) = xIn(2x)
To find the simplified expression for the rate of change of f'(x) integrate the function:
∫f'(x) dx = ∫xIn(2x) dx
Using integration by parts:
∫uv dx = uv - ∫u'v
After solving:
∫xIn(2x) dx = x²(2 ln(2x) - 1)/4 + c
Thus, the simplified expression for the rate of change of f'(x) is x²(2 ln(2x) - 1)/4 + c.

The equation of the line in slope intercept form with slope 1/3 and passes through ( - 6, 0) is y = 1/3x + 2.
In mathematics, the slope or gradient of a line is a number that indicates the line's steepness as well as its X and Y directions. The letter "m" stands for slope. The ratio of the "vertical change" to the "horizontal change" between any two separate points on a line is used to compute the slope.
The equation of the line in point-slope form is expressed as:
y - y₁ = m( x - x₁ )
where m is the slope.
So, m = 1/3
( x₁, y₁ ) is the point on the line = ( - 6, 0)
Substituting the values,
y - 0 = 1/3( x + 6 )
y = 1/3( x + 6 )
y = 1/3x + 6/3
y = 1/3x + 2
Hence, the equation in slope-intercept form of the line is y = 1/3x + 2.

Step-by-step explanation: A standard cube has 6 sides. The spinner has 4 sections. For any section of the spinner you land on, you can land on one of 6 sides of the dice.
The total number of outcomes is 24.
In probability theory, an outcome is a possible result of an experiment or trial.
Each possible conclusion of a particular experiment is unique, and many outcomes are incompatible (only one outcome will occur on each trial of the experiment). All possible outcomes of an experiment make up the elements of a sample space.There is a possibility that events with probabilities between 0 and 1 will occur (inclusively). Each outcome is given a probability inside a discrete probability distribution with a finite sample space. On the other hand, a continuous distribution only permits the assignment of non-zero probabilities to ranges of events, with all individual outcomes having a zero chance.When a number cube is rolled there are 6 distinct outcomes
{1,2,3,4,5,6} = 6
Again when a spinner is spun there are 4 possible outcomes
The total number of outcomes = 6 × 4 = 24
Hence there are 24 distinct outcomes.

Write the equation that is the translation of y = |x| left 9 units and up 11 units.
The translation of y = |x| left 9 units and up 11 units is y = |x+9|+11 .
The process of translating an existing graph or equation into a new graph is known as graph translation.
The alteration of algebraic equations is a typical form of algebraic challenge.A translation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of translation. The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).We know that for translation we have to change the x-coordinate and the y-coordinate by the amount that is stated in the translation.
Therefore from the graph we can see that the graph of y =|x| is represented by the blue line and the graph of translation y = |x+9|+11 is represented by the red line.

a 13-foot ladder is leaning against a wall. if we pull the ladder away from the wall at a rate of 6ft/s, how fast is the top of the ladder moving down the wall when the bottom of the ladder is 12ft from the wall?
Answer:
Below in bold.
Step-by-step explanation:
The relation between the height of the ladder and distance from the ground is given by Pythagoras Theorem:
h^2 = 13^2 - L^2
h = (169 - L^2)^1/2
Finding the derivative:
dh/dL = 1/2(169 - L^2)^-1/2 * -2L
= -L / (169 -L^2)^1/2
dL/dt = 6
So, dh/dt = dh/dL * dL/dt
= -6 * L/ (169 - L^2)^1/2
= -6 * 12 / (169 - 12^2)^1/2
= -72/5 ft /second
= -14.4 ft/second.
It's negative because the distance from the ground is decreasing.

Solve the following word problem using elimination. Set up a system of equations before solving in order to receive full credit.
The difference between two numbers is 4. The sum of the smaller number and three times the larger number is 36. What are the two numbers?
The two numbers are 10 and 6.
Now, let's take the larger number to be x and the smaller number to be y.
According to the question,
We have the following details:
The difference between two numbers = 4
So, we have the following expression:
(x-y) = 4 .... (1)
The sum of the smaller number and three times the larger number = 36
So, we have the following expression:
(3x+y) = 36 ....(2)
Now, we will use the elimination method to solve these equations. So, we will add equation 1 and 2.
(Please note that the left hand side is added to the left hand side and the right hand side numbers are added to the right hand side numbers.)
(x-y+3x+y) = (4+36)
4x = 40
x = 40/4 (4 is in multiplication on the left hand side. So, it is in the division on the right hand side.)
x = 10
Now, putting the value of x in equation 1,
(x-y) = 4 .... (1)
(10-y) = 4
-y = 4-10
-y = -6
y = 6
Hence, the larger number is 10 and the smaller number is 6.
