Any point satisfying the relation y = -[1 - (∛x²)]²(1/(∛x)) will be points on the graph where the tangent line has slope 1.
What is the slope of a given line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is the slope of a line is represented by the expression m = change in y/change in x =Δy/Δx.
Additionally, the slope of the line can be shown as tan θ = Δy/Δx
So, the slope of a line is tan θ.
The given equation is: (∛x²) + (∛y²) = 1
Therefore, (∛y²) = 1 - (∛x²) ⇒ y² = [1 - (∛x²)]³
Differentiating the equation formed with respect to x, we get
2y(dy/dx) = 3[1 - (∛x²)]²(-2/3)(1/(∛x)) ⇒ dy/dx = (-1/y)[1 - (∛x²)]²(1/(∛x)) -(i)
Given, the slope of the tangent line is = 1 -(ii)
Thus, equating (i) and (ii), we get,
(-1/y)[1 - (∛x²)]²(1/(∛x)) = 1 ⇒ y = -[1 - (∛x²)]²(1/(∛x))
Therefore any point satisfying the relation y = -[1 - (∛x²)]²(1/(∛x)) will be points on the graph where the tangent line has slope 1.

The length, d, of a violin string varies inversely as the frequency, f, of its vibrations (cycles per second). Suppose it is known that a 16-in.-long violin string vibrates 320 cycles per second.
A. Write an inverse variation equation modeling this information
B. Use your inverse variation equation from Part A to determine the frequency of an 8-inch-long violin string.
An 8-inch violin string has a frequency of 640 cycles per second using the inverse variation equation.
Who defines frequency?The pace of direction changes in current per second is known as frequency. It is expressed in hertz (Hz), a unit of measurement that is used internationally. One hertz is equivalent to one cycle per second. One hertz (Hz) is equivalent to one cycle per second.Given: A 16-inch violin string is known to vibrate at 320 cycles per second.
We know that,
Using the frequency equation where l for the length of the string and f for the frequency.
f = k/l
320 = k/16
k = 5120
So, the equation becomes f = k/l
For l = 8
f = 5120/8
f = 640
Therefore, the frequency of an 8-inch-long violin string is 640 cycles per second.

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by 4.9t² + 142t+ 346. h(t) Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?
A.The rocket splashes down after seconds. Round your answer to the nearest second.
B.How high above sea-level does the rocket get at its peak? The rocket peaks at meters above sea-level. Round your answer to the nearest meter.
a. The rocket splashes down after 31.23 seconds.
b. The rocket is 1374.7 meters above sea level.
NASA launches a rocket at t=0 seconds.
Its height, in meters above sea-level, as a function of time is given by
h(t)=-4.9t²+142t+346.
Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?
When splash down occurs, h(t) = 0, therefore
-4.9t²+142t+346 = 0
find t using the quadratic formula; a=4.9, b=142, c=346
t = -142 ± √(142)² - 4(-4.9)(346) / 2(-4.9)
t = -142 ± 164.15 / -9.8
t = -142+164.15/-9.8 , -142-164.15/-9.8
t = 22.15/-9.8 , -306.15/-9.8
t = -2.26 , 31.23
time cannot be negative so t = 31.23
The rocket splashes down after 35.8229 seconds.
The max occurs on the axis of symmetry, use x=-b/(2a) to find it
t = -142/2(-4.9)
t = 142/9.8
t = 14.48 sec
replace t with 17.2449 in the equation
h(t) = -4.9(14.48)² + 142(14.48) + 346
= 1374.7 m
The rocket peaks at 1374.7 meters above sea-level.
Hence we get the answers.

Oy=(x-4)²-22
Oy=(x-4)² + 22
O y = (x+4)² - 22
Oy = (x+4)² + 22
Answer:
C
Step-by-step explanation:
One of the quick ways of getting the answer is to graph the equation. I have done that for you at the bottom of this answer. However, I think you want the written solution.
Equation
y = x^2 + 8x - 6 Put brackets around the first 2 terms
y = (x^2 + 8x) - 6 Take 1/2 the second term and square
8/2 = 4; 4^2 = 16 Put 16 after the second term
y = (x^2 + 8x + 16) - 6 Subtract 16 and put it after the 6
y = (x^2 + 8x + 16) -6-16 Combine
y = (x^2 + 8x + 16) - 22
The first 3 terms make a perfect square (x^2 + 8x + 16) = (x + 4)^2
So the answer is between C and A
y = (x + 4)^2 - 22

Determine which integer(s) from the set S:{−18, 2, 15, 20} will make the inequality five sixths m minus four is less than one third m plus 5 false.
Number 20 from the set S:{−18, 2, 15, 20} will make the inequality five sixth "m" minus four less than one third "m" plus 5 false.
As per the question statement, we are supposed to find the integer(s) from the set S:{−18, 2, 15, 20} will make the inequality five sixth "m" minus four less than one third "m" plus 5 false.
Let's write the given statement in numeric form first, we get
[tex]\frac{5m}{6} -4 < \frac{m}{3} +5[/tex]
Let's solve the inequality for "m"
We get 3m/6 <9
or 3m <54
or m < 18
Therefore all values of m < 18 will make the inequality true and m>18 will make the inequality false.
The value of m > 18 in the above given set S:{−18, 2, 15, 20} is 20, hence number 20 from the set S:{−18, 2, 15, 20} will make the inequality five sixth "m" minus four less than one third "m" plus 5 false.

What is the equation of the line that passes through Point (3, -4) and has a Slope of 0.
Step-by-step explanation:
the slope of a line is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
a slope = 0 means that the y coordinate change is always 0, so y does not change anywhere on the line.
that makes y a constant c, and x can be any value completely independent of y.
the line is the summary of all points that have c as their y coordinate.
so, the general equation for such a line is simply
y = c
what is c ?
as we have one point on the line, remember the statement above : the line is the summary of all points that have c as their y coordinate.
that means (3, -4) must have the same y coordinate.
so, c = -4.
the equation of the line is therefore
y = -4

A line that passes through point (3,-5) and is perpendicular to y = -x+5 has the equation y = x - 8.
What is a straight line equation?A straight line has an equation of y=mx + c, where m is the gradient and c is the constant, also known as the y-intercept, at which the line crosses the y-axis.
How do you determine the line's equation?In order to put the equation in y-intercept (y = mx + b) form and determine the equation of a graphed line, first determine the slope and y-intercept.
It is given that a line's equation passes through point (3,-5) and is perpendicular to y = -x+5.
Slope of given line = -1
Slope of line perpendicular to the given line = Negative of the reciprocal of the slope of a given line = 1
We have the slope and point (3,-5) of the required line. So, we can find the constant of this equation.
y = mx + c
-5 = 1(3) + c
c = -5 - 3
c = -8
Substituting c = -8 and m = 1 to get the equation of required line.
y = mx + c
y = x - 8
As a result, the equation of a line passing through point (3,-5) and perpendicular to y = -x+5 is y = x - 8.

Given equal probabilities of the birth of a xy or xx, what is the probability that a group of four siblings includes all xy? all xx? all xy or all xx?.
The probability that a group of four siblings includes all XY is 1/16 (6.5%), while the probability all XX offspring is 1/16 (6.5%). It is a simple genetic probability calculation.
Genetic probabilities and chromosomes
Females inherit two chromosomes X, whereas males inherit one chromosome X and one chromosome Y.
The probabilities of inherent two chromosomes X (females) are 1/2 (50%), while the probabilities of inherent one chromosome X and one chromosome Y (males) are also 1/2.
In consequence, the probability that a group of four siblings includes all XY is 1/16 (because it is equal to 1/2 x 1/2 x 1/2 x 1/2 = 1/16), the same for the probability all XX offspring (1/16).
