Which of the following expressions is accurate for angle 8 that intersects the unit circle at point (-0.949, 0.314).
Cos(0) = - 0.949 this expression is accurate for the unit circle which is intersected at point by angle 8 according at point (-0.949, 0.314).
What is circle ?An elliptical plane figure is a circle. From a fixed location known as the circle's center, each point on the circle is equally distant. It has a two-dimensional (2D) shape and a radius value. The Latin word "circulus" (which means little ring) is the root of the English word "circle."A circle is a two-dimensional shape that is made up of a collection of points that are spaced out from the center of the circle (its fixed point) on the plane by a fixed or constant distance (radius). The radius of a circle is the fixed distance between points that is fixed from the fixed point, which is known as the origin or center of the circle.
The terminal side of angle 0 intersects the unit circle at point P(- 0.949, 0.314) That means, OQ = 0.949 and PQ = 0.314
Here, OP is the radius of the unit circle. So, OP = 1
In respect of angle 0, the adjacent side is OQ and the hypotenuse is OP.
We know that,
cos= [tex]\frac{adjacent}{hpotenusey}[/tex]
So,
cos(0) = - [tex]\frac{OQ}{OP}[/tex] [As the angle is in quadrant II, so cos is negative]
cos(0) = - [tex]\frac{-0.949}{1}[/tex]
cos(0) = - 0.949
Cos(0) = - 0.949 this expression is accurate for the unit circle which is intersected at point by angle 8 according at point (-0.949, 0.314).

The unknown angles of the triangle and trapezium are as follows:
∠1 = 110°, ∠2 = 40°∠1 = 120°, ∠2 = 60°How to find angles in a triangle and trapezium?A triangle is a polygon with three sides.
The sum of angles in a triangle is 180 degrees.
Therefore, angle 1 can be found as follows:
∠1 = 180 - 40 - 30
∠1 = 180 - 70
∠1 = 110 degrees.
Therefore, angle 2 can be found as follows:
∠2 = 180 - 40 - 40 - 30 - 30
∠2 = 180 - 80 - 60
∠2 = 180 - 140
∠2 = 40 degrees.
A quadrilateral is a polygon with 4 sides. The sum of angles in a quadrilateral is 360 degrees.
Therefore, the triangle in the trapezium is an isosceles triangle. The base angles are equal.
Hence,
∠1 = 180 - 30 - 30
∠1 = 180 - 60
∠1 = 120 degrees
Sum of angles in the same transversal is supplementary.
Therefore,
90 + 30 + ∠2 = 180
∠2 = 180 - 120
∠2 = 60 degrees

Find the area of a rectangle that is 2 7/9 m long and 4 4/5 m wide. Enter your answer as a mixed number and reduce if possible.
Answer:
13 ⅓.
Step-by-step explanation:
The area of a rectangle is given by
Area = Length × Breadth
Length = 2 7/9 = 25/9 and breadth = 4 4/5 = 24/5
.: Area = 25/9 × 24/5 = 600/45 (15 can go to both the numerator and denominator)
We have 40/3 but to convert it to a mixed fraction we get 13 ⅓ as your area.
What is the equation of the line that is perpendicular to y = 3x + 3 and passes through the point (−6, 9)?
The equation of the line will be equal to 3y = -x + 21.
A line may be defined as the straight figure drawn which has no end points. The equation of a line can be written in slope intercept form as y = mx + c where m is the slope of line, c is y intercept an x and y are independent and dependent variables. If a point (x₁, y₁) is given then equation of line is (y - y₁) = m (x - x₁). The slope of line which is perpendicular to a given line having slope m is equal to -1/m.
Now, equation of line is y = 3x + 3. If we compare with slope intercept form then, m = 3. Now, slope of line perpendicular to this line is equal to -1/3. Now, equation of line passing through point (-6, 9) is given as
(y - 9) = -1/3 (x + 6)
3y - 27 = -x - 6
=> 3y = -x + 21 which is the required equation of line.

(Type an integer, fraction, or mixed)
Integer - 19 (1/8)inch board would be left after cutting from 34(1/4) inch board
What is an Integer ?
Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. When expressed in mathematical terms,
34 (1/4) inch board = 137/4 ----(1)
Cut piece = 14 3/4 = 59/4 ----(2)
saw cut 3/8 = 3/8 --------(3)
To calculate the board which is left after cutting will be
= 137 / 4 - 59 / 4 - 3/8
= 137 - 59 / 4 - 3 / 8
= 39 / 2 - 3 / 8
= 312 - 6 / 8

y = 1 / 3 x + 5 is the linear equation for the first table.
The system of equations' answer is (3, 6).
Linear Equation: What Is It?A linear equation is an algebraic equation of the form y= mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The previous equation, which has the variables y and x, is sometimes referred to as a "linear equation with two variables."
based on the available facts;
Equation of a point slope:
y = mx + b,
where m = slope and b = y-intercept
As a result, the equation for the second table is y = - 1 /3 x + 7.
With the help of the table's (0, 5)(3, 6) values, the equation for the first table may be solved. Therefore,
m = 6 - 5 / 3 - 0 = 1 / 3
let's find b using (0, 5)
5 = 1 / 3(0) + b
b = 5
Therefore, the equation of the first table is as follows:
y = 1 / 3 x + 5
The solution to the system of equation can be calculated as follows:
y + 1 /3 x = 7
y - 1 / 3 x = 5
2y = 12
y = 12 / 2
y = 6
6 - 1 / 3 x = 5
- 1 / 3 x = 5 - 6
- 1 / 3 x = - 1
x = 3
Therefore, the solution to the system of equation is (3, 6)

Zeke learned that he could make another
$2,000 a year if he became fluent in Spanish.
If he intends to learn the language and work another 10 years at that job, how much is learning Spanish worth to him?
If Zeke learned that he could earn another $2000 a year if he become fluent in Spanish and he intended to learn the language and work another 10 years at that job, then the amount is learning Spanish worth to him is $20000
The extra amount he could make if he learn Spanish = $2000
The number of years he works = 10 years
To find the extra amount, we have to use multiplication
The extra amount he could make if he learn Spanish = The extra amount he could make if he learn Spanish × The number of years he works
Substitute the values in the equation

The equation of the line perpendicular to the line −7x+2y=3 having the same y-intercept as 9x+3y=−2 is y = - 2 / 7x - 2 / 3
How to find equation of a line?The equation of a line can be represented as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line is perpendicular to −7x+2y=3.

At the end of a snow storm, Julian saw there was a lot of snow on his front lawn. The
temperature increased and the snow began to melt at a steady rate. Let S represent
the depth of snow on Julian's lawn, in inches, t hours after the snow stopped falling.
A graph of S is shown below. Write an equation for S then state the z-intercept of
the graph and determine its interpretation in the context of the problem.
answer:
the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.
The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.
Step-by-step explanation:
the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.
The rate of melting is 1.5inches per hour.
At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start
At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.
