The θ lies in the 4th quadrant of the graph.
Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circle functions) that make up trigonometry.The coordinate plane system's four quarters are referred to as quadrants. A quadrant is the name of one of the four divisions. A quadrant, or sector of 90 degrees, is the term used to describe a circle's quarter.In the question, Cosθ = 4/7 and Sinθ is negative.Cosθ is positive in the 1st and 4th quadrants.Sinθ is negative in the 3rd and 4th quadrants.Thus, θ lies in the 4th quadrant of the graph.To learn more about quadrants, visit :

Change 23 out of 25 to a percentage
This how we change 23 out of 25 to a percentage
The numerator of a question is the number that appears above the bar; in this case, the numerator is 23.
The denominator is the number beneath the bar, and in this question, it is 25.
To calculate the value of a fraction, divide the numerator by the denominator.
Therefore, we must divide 23 by 25.
23/25 = 0.92
To determine the percentage, multiply the outcome by 100.
The percentage value will be obtained by multiplying 0.92 by 100.
0.92 x 100 = 92%
As a result, 92% is the answer to the question.

B.
√134
C.
√115
D.
√121
√134 is the number which is located between 11 and 12 on a number line.
What is a Number Line?A number line is a horizontal straight line on which real numbers are arranged in equal intervals. This line extends both sides at infinity.
Comparison and operations of numbers can be better explained using number lines.
Taking consecutive perfect squares of integers which lies above and below the given numbers on the number line and taking it's square root, we can find the answer.
The perfect squares below and above 150 are 144 = 12² and 169 = 13². So √150 lies in between 12 and 13.
The perfect squares below and above 134 are 121 = 11² and 144 = 12². So √134 lies in between 11 and 12.
The perfect squares below and above 115 are 100 = 10² and 121 = 11². So √115 lies in between 10 and 11.
The number 121 is itself a perfect square. √121 = 11.
Hence √134 is the number which lies in between 11 and 12.

The table shows a country’s average fuel consumption for light duty vehicles for several years. Let XP the number of years since 1985 so that executes five cents for 1990 and so forth. Find the linear regression model for the status. What does slope and regression model represent
Using linear function concepts, it is found that:
The slope is of 0.172 means that the fuel economy increases by 0.172 mpg each year.The intercept of 17.04 means that the fuel economy was of 17.04 mpg in 1985.What do the slope and the intercept of a linear function represent?The slope-intercept representation of a linear function is:
y = mx + b.
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, we will use a calculator from the points on the table to build a linear function of best-fit. The points are given as follows:
(5, 17.9), (10, 18.7), (15, 19.7), (20, 20.5), (25, 21.3).
Then the function is:
y = 0.172x + 17.04.
Then:
The slope is of m = 0.172, meaning that each year, the fuel economy increases by 0.172 mpg.The intercept of b = 17.04 was the fuel economy in 1985.What is the missing information?The table is missing, and is given by the image at the end of the answer.

cos^4x - sin^4x +1 = 2cos^2x
prove
Proved [tex]Cos^{4}x - Sin^{4}x + 1[/tex] = 2Cos²x
We will use the Pythagorean Theorem:
Sin²x + Cos²x = 1
from which we can get:
Sin²x = 1 - Cos²x
Also, note that the difference in the similarity of squares can be written:
A² - B² = (A - B)
We can use this with A = Sin²x and B = Cos²x as follows:
[tex]Sin^{4}x - Cos^{4}x[/tex]
= (Sin²x)² - (Cos²x)²
= (Sin²x - Cos²x) (Sin²x + Cos²x)
= Sin²x - Cos²x

Write an equation for the line that is parallel to the given line y=3/4x + 7 and that passes through the given point G(8,3)
The equation for the line that is parallel to the given line y=3/4x + 7 and that passes through the given point G (8,3) is y= (3/4)x -3.
As given in the question,
Equation of the given line :
y=3/4x + 7
Slope of the given line = (3/4)
Equation of line with slope (3/4) & passing through point (8, 3) is given by:
y - 3 = [tex]\frac{3}{4}[/tex] (x - 8)
⇒ 4 (y - 3) = 3 (x - 8)
⇒ 4y - 12 = 3 x - 24
⇒ 4 y = 3 x - 24 + 12
⇒ 4 y = 3 x - 12
⇒ y = (3/4)x - 3
Therefore, the equation for the line that is parallel to the given line
y=3/4x + 7 and that passes through the given point G (8,3) is y= (3/4)x -3.

4. Find “a” so that the parabola y = ax² + 3x + 11 goes through the point (3,2).
Answer:
a = - 2
Step-by-step explanation:
since the point (3, 2 ) lies on the parabola, then it makes the equation true.
substitute x = 3, y = 2 into the equation and solve for a
y = ax² + 3x + 11
2 = a(3)² + 3(3) + 11
2 = 9a + 9 + 11
2 = 9a + 20 ( subtract 20 from both sides )
- 18 = 9a ( divide both sides by 9 )
- 2 = a
Answer:
a = -2
Step-by-step explanation:
Given quadratic equation:
[tex]y=ax^2+3x+11[/tex]
In order to find "a", substitute the given point on the curve (3, 2) into the equation and solve for a:
[tex]\begin{aligned}y&=ax^2+3x+11\\\textsf{Substitute $(3,2)$} \implies 2&=a(3)^2+3(3)+11\\2&=9a+9+11\\2&=9a+20\\2-20&=9a+20-20\\-18&=9a\\9a&=-18\\\dfrac{9a}{9}&=\dfrac{-18}{9}\\\implies a&=-2 \end{aligned}[/tex]
Therefore, the value of "a" so that parabola y = ax² + 3x + 11 goes through the point (3, 2) is:

What is a line segment?A line segment can be defined as the part of a straight line that is being bounded by two different end points, and also contains all the points on the line between its endpoints.
From the information given, we have that line AD is a line with segments, line AB, line BC, line CD with B and C as the midpoints.
Given the points as;
AC = x + 23BD = 12BC = 14 + xAD = 26 + xWe have that;
AC + BC = AD
But line BD = 14 + x, we have;
Line AC = x + 23 - 14 + x
Line AC = 2x + 9
substitute the values into the equation
2x + 9 +12 = 26 + x
collect like terms
2x - x = 26 - 21
Add or subtract like terms
x = 5
But, we have that;
Line AC = x + 23
Line AC = 5 + 23
Add the values
Line AC = 28
Hence, the value is 28
