To read 8 pages, Shirley needs 40 minutes. At that rate, how many minutes does she need to read each page
She need 5 minutes to reach each page.
What is constant rate?In mathematics, the absence of acceleration is referred to as a constant rate. A function that has a constant rate typically has a second derivative of 0.
The function would be plotted as a straight line on a piece of graph paper if the change in y (or rate) were constant. When anything moves at a fixed, steady pace or at an average speed, it is said to be moving at a constant rate, also known as a uniform rate. For instance, 3 hours pass while driving. In the first hour, it travels 30 miles, in the second hour, 45 miles, and in the third hour, 75 miles.
Given,
time she needs to read 8 pages = 40 minutes
time she needs to read 1 pages = 40/8

When comparing functions, such as Seth’s scenarios for travelling to school, will the function with the greatest initial value continue to be the greatest as time increases?
No. The pace of change affects the y-value, therefore having a higher beginning value does not guarantee it. The output may decrease if the function with the bigger beginning value has a slower rate of change.
This is further explained below.
What are functions?Generally, No. Even if the function had a higher beginning value, it does not always follow that it would always have a higher y-value. This is because the y-value also relies on the rate of change.
In conclusion, If the function with the higher beginning value has a slower rate of change, it is possible that the output may become smaller at some time in the future as a consequence of this.

Answer:
-1.47, 1.14 to 2 decimal places.
Step-by-step explanation:
3x^2 + x - 5 = 0
3(x^2 + 1/3x) - 5 = 0
Completing the square on the expression in the parentheses:
3[(x + 1/6)^2 - 1/36) - 5 = 0
3(x + 1/6)^2 - 1/12 - 5 = 0
(x + 1/6)^2 = 61/12 / 3
(x + 1/6)^2 = 61/36
(x + 1/6) = +/-√61 / 6
x = -1/6 +/- √61 / 6
x = 1.135, -1.468
a traffic light at a certain intersection is green 55% of the time, yellow 10% of the time, and red 35% of the time. a car approaches this intersection once each day. let y denote the number of days up to and including the third day on which a red light is encountered. assume that each day represents an independent trial.
The probability of the car encountering it's first red light on the third day, i.e., P(Y = 3) will be 0.1479
As per the question statement, assuming that "Y" denotes the number of days pass up to and including the first day on which the car encounters a red light, a traffic light at a certain intersection is green 55% of the time, yellow 10% of the time, and red 35% of the time and a car approaches this intersection once each day.
We are required to calculate the probability of the car encountering it's first red light on the third day, i.e., P(Y = 3)
Here, Probability of encountering a Red light = 0.35, since traffic light at the intersection is red 35% of the time.
And "Y" is the number of days that pass up to and including the first time the car encounters a red light, i.e.,
The distribution here is a geometric one, where
P(Y = 3)
= P(Not red light in initial 2 lights) * P(red light in third light)
= [(1 - 0.35)² * 0.35]
= 0.1479
Probability: It is a branch of Mathematics, that deals with the numerical descriptions concerning the extent to which an event is likely to occur, or how likely it is for a proposition to be true, and is measured by the ratio of the favorable cases to the whole number of cases possible.

Triangle ABC is congruent to triangle A'B'C'. Describe a sequence of rigid motions
that takes A to A', B to B', and C to C'.
The transformations that take triangle ABC to triangle A'B'C' are given as follows:
Reflection over the line y = B.
Translation up and right.
These following categories are used to group transformations on a function's graph.
Translation: The figure's position can be changed by moving to the left, right, or up/down.
Reflections: These can occur over a line or on one of the axes, shifting the direction that the figure is facing.
Rotations: Changing the figure's inclination across a degree measure.
Dilation: The scale factor is multiplied by the coordinates of the original form's vertices, affecting the side lengths of the figure.
The modifications brought about by these transitions are particularly significant in the context of this issue.
For this issue, the triangle's orientation altered, causing a reflection to take place. Since B was the bottom vertex of ABC and is now at the top of A'B'C', the line of reflection is y = B.
B and B' would be in the same place if it weren't for the reflection. A translation up and right was also utilized because A'B'C' lies above and to the right of the line of reflection.
There were no rotations or dilations because the inclination and side lengths were constant.

Answer:
x = 12 is the x-axis intercept
Step-by-step explanation:
'x-intercept' is short for 'x-axis intercept' <==== when the graph crosses the x axis, y = 0 so put y = 0 in the equation
y = -2/3 x + 8
0 = -2/3 x + 8
-8 = - 2/3x

Answer: x = 72 degrees
Step-by-step explanation:
A Pentagon has 540 degrees in total
Divide 540 by the number of angles you have
540 / 5 = 108 degrees
The x angle is on a flat line with the other angle, when you add them you will get 180
So subtract 108 from 180
180 - 108 = x = 72 degrees

Step-by-step explanation:
The triangle on the right is an equilateral triangle. This means each angle is 60 degrees.
The bottom angle which goes over both triangles is marked as a right angle (90 degrees). Given that the part of that angle in the equilateral triangle is 60 degrees, the rest of the angle (i.e. the part of the angle in the other triangle) is 30 degrees.
It is implied by the markings that the angle x = the other angle at the top (although this should be clearer). Assuming this is the case, we can use the rule that angles in a triangle sum to 180 degrees, to say that:
x + x + 30 = 180
Combine like terms, rearrange and simplify:
2x + 30 = 180
2x = 150
x = 75
Given f(x) = 3x³ + kx- 10, and x - 2 is a factor of f(x), then what is the value of k?
Polynomial equations are used to encode a wide range of problems, from simple word problems to complex scientific problems. Therefore, the value of k is -7.
What are Polynomials?A polynomial is an expression in mathematics made up of coefficients and indeterminates, which are also known as variables. It can only be solved using the addition, subtraction, multiplication, and powers of positive-integer variables. For instance, x3 + 2xyz2 yz + 1 has three indeterminates. Value In both mathematics and science, polynomials are widely used. For instance, they are used to define polynomial functions, which can be found in a variety of contexts, from basic chemistry and physics to economics and social science, and they are used in calculus and numerical analysis to approximate other functions. If f(x) = 3x³ + kx- 10 , If x -2 is a factor of the given equation, then,x - 2 = 0 ⇒ x = 2, On substituting, x =2, f(x) = f (2) = 0.So, f (2) = 3(2) ³ + k2- 10 = 0⇒ 24 + 2k -10 = 0 and 2k = -14⇒ k = -14/2, so k = -7In higher mathematics, polynomials are employed to build algebraic varieties and polynomial rings, which are fundamental ideas in algebra and algebraic geometry.To learn more about Polynomials, refer to:

Write the equation of a parabola with x-intercepts at (3, 0) and (9, 0) that
passes through the point (10, -7).
The parabola's equation is y = -x2 + 12x - 27.
A parabola is a point's location where the focus and a fixed point's distance from a fixed line, known as the directrix, are the same.
A parabola's equation is in quadratic form.
Thus, it is stated as:
Y = Ax2, Bx, and C
Located at (3, 0):
0 = a(3²) + b(3) + c
9a + 3b + c = 0 (1) (1)
Located at (9, 0):
0 = a(9²) + b(9) + c
81a + 9b + c = 0 (2) (2)
Located at (10, -7):
-7 = a(10²) + b(10) + c
100a + 10b + c = -7 (3) (3)
Equations 1, 2, and 3 are solved to yield: a = -1, b = 12, and c = -27.
