Final answer:
The equation for Omar's total pay after working h hours at $8 per hour is p = 8h. This linear equation indicates a direct proportion between hours worked and total pay, reflecting a total of $64 for an 8-hour day.
Explanation:
The equation to represent Omar's total pay, p, after working h hours, at the rate of $8 per hour, is given by p = 8h. This linear equation shows that the total pay is directly proportional to the number of hours worked. Therefore, if Omar works for a standard 8-hour day, he would earn 8 hours times $8 per hour, which equals $64 for that day.

How can you decompose the composite figure to determine its area?
In order to find the area of the given figure we have to decompose into geometrical figures whose area could be easily calculated by the use of the mathematical formulas we know.
Hence, we decompose it into:
1 semicircle. 2 trapezoids with one common base. 1 rectangle.The decomposition could be seen with the help of diagram attached to the answer.
Answer:
as two semicircles and a rectangle

Consider the graph of the quadratic function y = 2x2 – 4x + 2. How many zeros does the graph have?
The graph has:
One zero with multiplicity 2.
Step-by-step explanation:We are given a quadratic function in terms of the variable x as:
[tex]y=2x^2-4x+2[/tex]
The number of zeros of this function is equal to the number of points where the graph of this quadratic function intersects the x axis and the corresponding value of x is the root of this quadratic equation.
Hence, after plotting the graph of this quadratic function we observe that the graph meets the x-axis at just one point.
Hence, the number of zeros of the graph is:
One.

Step-by-step explanation:
A wildlife biologist is interested in the relationship between the number of chirps per minute for crickets (y) and temperature. based on the collected data, the least-squares regression line is y x ˆ = + 10.53 3.41 , where x is the number of degrees fahrenheit by which the temperature exceeds 50°. give a sentence that describes the meaning of the slope of the least-squares regression line
Final answer:
The slope of 3.41 in the least-squares regression line y = 10.53 + 3.41x indicates that for every one degree Fahrenheit increase in temperature above 50°, the number of cricket chirps per minute is expected to increase by an average of 3.41 chirps.
Explanation:
The slope of the least-squares regression line in the relationship between the number of chirps per minute for crickets (y) and temperature is 3.41. This number represents the average increase in the number of chirp per minute for every degree Fahrenheit that the temperature is above 50°. Therefore, if the temperature increases by one degree Fahrenheit, the expected number of cricket chirps per minute increases by an average of 3.41 chirps.
The slope of the least-squares regression line, which is 3.41, indicates that for every degree Fahrenheit the temperature exceeds 50°, the number of chirps per minute for crickets increases by 3.41 chirps.
In a linear regression equation of the form y = a + bx, the slope (b) represents the change in the dependent variable (y) for a one-unit change in the independent variable (x).
In this context, the slope (b) is 3.41, which means that for each additional degree Fahrenheit above 50°, the model predicts an increase of 3.41 chirps per minute by the crickets.
The intercept of the regression line is 10.53, which represents the baseline number of chirps per minute when the temperature is exactly 50°F.
The complete question is:
A wildlife biologist is interested in the relationship between the number of chirps per minute for crickets (y) and temperature. Based on the collected data, the least-squares regression line is yˆ = 10.53 + 3.41x, where x is the number of degrees Fahrenheit by which the temperature exceeds 50°. Give a sentence that describes the meaning of the slope of the least-squares regression line.
simplify i^31 (click photo for options)
The required solution of i^31 is -i.
What is simplification?Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given expression is,
i^31
This can be written as,
= i^(30+1)
or, we can express it as,
= i^30 . i
or, we can write,
= (i^2)^15 . i
Since i^2 = -1
Therefore we can write,
= (-1)^15 . i
Again since, (-1)^15 = -1
Thus,
i^31 = -i
which is the required solution of the given expression.
Thus, the required solution of i^31 is -i.

the difference between the measures of two complementary angles is 46. determine the measures of the two angles?
Final answer:
To determine the measures of two complementary angles with a 46-degree difference, you can set up an equation and solve for the angles, resulting in approximately 22.0 degrees and 68.0 degrees.
Explanation:
Complementary angles are two angles that add up to 90 degrees. If the difference between them is 46 degrees, we can set up an equation to find their measures:
Let one angle be x. The other angle would then be 90 - x.
Given that the difference between them is 46, we have the equation: 90 - x - x = 46.
Solving the equation, the angles are approximately 22.0 degrees and 68.0 degrees.

Answer:
Angle Side Angle
Step-by-step explanation:
Here, the following triangles are congruent by using Angle Side Angle
∠c=∠F(90°) (Angle)
BC=EF (Given) (Side)
∠B=∠E (Given) (Angle)
By using Angle Side Angle criteria, we can say that
Both the triangles are congruent
Hence, Both triangles are congruent by using ASA criteria.
