Answer:
Below
Step-by-step explanation:
To find the slope of a line, we use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
In this case, if Akio recorded the distance he rode on his bike ride in hours, the slope of the line for the first two hours would be the change in the y-coordinates (distance) divided by the change in the x-coordinates (time) between those two points.
To find the slope of the line for all five hours, we will need to know the specific coordinates of all five points, otherwise, it's impossible to calculate the slope.
The slope of a line represents the rate of change in the y-coordinates (distance) per unit of change in the x-coordinates (time). In this situation, the slope represents Akio's speed, since the change in distance is divided by the change in time. A positive slope indicates an increase in distance over time, which means Akio is getting faster, whereas a negative slope indicates a decrease in distance over time, which means Akio is getting slower.
It's worth noting that a slope of zero would mean that there is no change in distance over time, which would mean that Akio isn't moving.

Is the inverse of a parabola a function?.
There is no inverse of the parabola function
An open curve or conic section known as a parabola is created when a right circular cone and a plane perpendicular to one of the cone's elements cross. It is a quadratic equation-defined symmetric U-shaped curve. A function's inverse is the graph of the function projected over the line y=x.
There is no inverse function for the parabola because it is not a one-to-one function. A one-to-one function is one in which every element in its domain corresponds to precisely one element in its range. It's not a one-to-one function in a parabola because as the x value increases, the y value might take a variety of values and vice versa. It can't be inverted because of this.

what is the slope and y-intercept of the graph below?
The y-intercept is 1 at the position (0,1) when x is 0 and y is 1.
What are the graph's slope and y-intercept?When the line to be examined's slope is known, and the provided point also serves as the y intercept, the slope intercept formula, y = mx + b, is utilized (0, b).
B stands in for the y value of the y-intercept point in the formula.
The y-intercept of a graph is the place where it crosses (or contacts) the y-axis, according to the definition of y-intercept.
The x-coordinate is known to be zero on the y-axis.
Therefore, the equation for determining the y-intercept of a function y = f(x) just requires the substitution of x = 0 and y-solving.
The slope is the ratio of Y change to x change:
Slope = (0-1) / 4-0) = -1/4
Slope = -1/4

What is the nature of roots of the quadratic equation 5?.
The nature of roots of the quadratic equation 5x^2 - 2x + 3 = 0 is complex number.
The nature of roots of a quadratic equation is determined by the discriminant, which is the value of b² - 4ac. In this case, the quadratic equation is 5x^2 - 2x + 3 = 0.
To find the discriminant, we can use the formula: b² - 4ac. In this case, a = 5, b = -2 and c = 3, so the discriminant is:
Discriminant = (-2)² - 4*5*3 = 4 - 60 = -56
The discriminant can be used to determine the nature of the roots:
If the discriminant is greater than 0, the roots are real and distinct.
If the discriminant is equal to 0, the roots are real and identical (i.e., the equation has only one root).
If the discriminant is less than 0, the roots are complex and not real numbers.
In this case, the discriminant is negative, so the roots of the equation 5x^2 - 2x + 3 = 0 are complex. The roots can be found by factoring the equation into (x + a + bi)(x + a - bi), where a and b are real numbers, and i is the imaginary unit (i² = -1).

Evaluate 1/2yz
if y= 3/5
and z= −1 7/8
Write your answer as a fraction in simplest form.
To evaluate 1/2yz when y = 3/5 and z = -17/8, we first substitute the given values for y and z into the expression:
1/2(3/5)(-17/8)
Next, we can simplify this by multiplying the fractions:
1/2 * 3/5 * -17/8 = (-3/10) * (-17/8)
To multiply the fractions we multiply the numerators and denominators separately:
(-3/10) * (-17/8) = (-3 * -17)/(10 * 8)
Then we can simplify the numerator by combining like terms:
(-3 * -17)/(10 * 8) = 51/40

How do you write an equation of a parabola with vertex at the origin and the given Directrix?.
The parabola's conventional form is y^2=4ax, which results in a parabola with an axis parallel to the x-axis, a vertex at the origin, a focus at (a,0), and a directrix at (x=a).
Since a=2 in your example, y^2=4ax is the result. The y-axis serves as the parabola's axis. The directrix equation is y = -a, which is equivalent to y = -12. There is a parabola's vertex at (0,0).
You must be aware that a parabola's equation in a vertex form is y=a(xh)^2+k, where a stands for the equation's slope, in order to determine the focus of a parabola. We can deduce from the formula that the parabola's focus lies at (h, k+1/4a).

Express the lengths a and b in the figure in terms of θ.
The lengths a and b be value of a = 24 sinθ, and b = 24 cosθ.
What is meant by SOHCAHTOA?
sinθ = opposite / hypotenuse
cosθ = adjacent / hypotenuse
tanθ = opposite / adjacent
The side that touches the angle but is not the hypotenuse is referred to as the adjacent side, while the side that is immediately across from the angle is referred to as the opposite side and does not touch the angle. The triangle's longest side is always the hypotenuse.
This information allows us to identify an as the opposing side and b as the neighboring side. Now all you have to do is utilize your angle to get the value of these lengths using SOHCAHTOA.
Since an is the opposite side, we shall utilize sine for it. Keep in mind that your hypotenuse is 24; therefore, we can enter in the data we have and solve for the missing lengths:
sinθ = opposite / hypotenuse
= a / 24
a = 24sinθ
For b, because it is the adjacent side, we will use cosine.
cosθ = adjacent / hypotenuse
= b / 24
b = 24cosθ
Therefore, the value of a = 24sinθ, and b = 24cosθ.

The cost of lower and upper level seats are $28 and $18 each, respectively.
Let x be the cost of the lower level seats
We know that the upper level seats are $10 cheaper, so their cost can be expressed as the algebraic expression x - 10.
We also know that the total number of seats is 8000, and 3000 of them are upper level seats, and a sellout has a total revenue of $194 000.
So we can set up the following algebraic equation:
(8000 - 3000)x + 3000(x - 10) = 194 000
Simplify the equation and solve for the value of x.
5000x + 3000x - 30 000 = 194 000
8000x = 224 000

The function f(x) is [tex]-32(x - 2)(x + 2)^2.[/tex].
A linear function has the equation f(x) = mx + b, where m is the slope and b is the y-intercept. In this case, g(x) is a linear function with an x-intercept of 2 (meaning it passes through the point (2,0)) and a slope of 4. So the equation for g(x) would be:
g(x) = 4(x - 2)
A quadratic function has the equation f(x) = [tex]a(x - h)^2[/tex] + k, where (h, k) is the vertex of the parabola. In this case, h(x) is a quadratic function with vertex (-2, -8) and passing through the origin (0, 0) so the equation for h(x) would be:
h(x) = [tex]-8(x + 2)^2[/tex]
Now since f(x) = g(x) ⋅ h(x), we can substitute the equation of g(x) and h(x) in the equation of f(x) to get the equation for f(x) :
f(x) = [tex]g(x) *h(x) = (4(x - 2)) * (-8(x + 2)^2)[/tex]

If xx represents the number of tables sold and yy represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
PLEASE HELP THIS IS AN EMERGENCY
The inequality expression and solution to a system of inequalities graphically is xx + yy <= 18
We can represent the system of inequalities as follows:
xx + yy <= 18 (representing the maximum number of pieces of furniture that can be shipped)
A possible solution could be:
xx = 8 (number of tables sold)
yy = 10 (number of chairs sold)
How do we express the inequality?100yy + 450xx >= 3200 (representing the minimum amount of money that must be made from the sale of chairs and tables)
xx >= 8 (representing the minimum number of tables that must be sold)
To graphically represent this system of inequalities, we can begin by graphing the first inequality in a coordinate plane. The inequality xx + yy <= 18 can be represented by a line with the equation y = -x + 18.
Next, we can graph the second inequality. The inequality 100yy + 450xx >= 3200 can be represented by a line with the equation y = -(4.5/5)x + 80.
Finally, we can graph the third inequality, which is a horizontal line at y = 8.
Now we can graph these three inequalities, one line for each inequality, and see where they intersect. The point where all three lines intersect is one possible solution for the system of inequalities.
A possible solution could be:
xx = 8 (number of tables sold)
yy = 10 (number of chairs sold)

Since the triangle is a right triangle, we can use the Pythagorean theorem to find the value of the angle.
For ∠A:
c^2 = a^2 + b^2 - 2ab * cos(A)
9^2 = 5^2 + 7^2 - 257 * cos(A)
81 = 25 + 49 - 70 * cos(A)
81 = 74 - 70 * cos(A)
81 - 74 = -70 * cos(A)
7 = -70 * cos(A)
cos(A) = -7/70
A = arccos(-7/70)
For ∠B:
a^2 = b^2 + c^2 - 2bc * cos(B)
5^2 = 7^2 + 9^2 - 279 * cos(B)
25 = 49 + 81 - 98 * cos(B)
25 = 130 - 98 * cos(B)
130 - 25 = 98 * cos(B)
105 = 98 * cos(B)
cos(B) = 105/98
B = arccos(105/98)
For ∠C:
b^2 = a^2 + c^2 - 2ac * cos(C)
7^2 = 5^2 + 9^2 - 259 * cos(C)
49 = 25 + 81 - 90 * cos(C)
49 = 106 - 90 * cos(C)
106 - 49 = 90 * cos(C)
57 = 90 * cos(C)
cos(C) = 57/90
C = arccos(57/90)
Keep in mind that the values of the angle are in radians.
Please note that the triangle does not have to be a right triangle, the Law of Cosines works for any triangle.

When we put the following numbers in ascending order, the order becomes 790×10^-3 < 0.0079 × 10^3 < 79 < 7.9 × 10^2.
In ascending order, we need to arrange any given set of data in such a way that the smallest number comes first, and then comes the next bigger number, and then the next bigger, and so on. The largest number in that given data set comes at the end. We have to arrange the following in such a manner as well.
Since we can deduce that 790×10^-3 is the smallest of the lot, it comes first. The next bigger number is 0.0079 × 10^3 and so, it comes right after that. Just after this is the number 79 and then, the largest number of this data set is 7.9 × 10^2 and so, it is at the last. Hence, the order is as such -
= 790×10^-3 < 0.0079 × 10^3 < 79 < 7.9 × 10^2.
