Find the slope and y -intercept of each line.
y=0
Here, slope is 0 and y-intercept is zero too as line y=0
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that the equation for slope(m) and y - intercept(c) of a line is given by :
y = mx + c
As here y is 0
then, 0 = (0)x + 0
Therefore, slope is 0 and y - intercept is zero too

Write the function rule for each function reflected in the given axis.
f(x) = x+1 ; x - axis
Functions can be reflected on the x-axis, the y-axis, or both axes. For example, function reflection y= f(x) can be written as y= -f(x) or y= f(-x) even y= -f(-x). There are four types of function or graph transformations: reflection, rotation, translation, and dilation. In mathematics, especially geometry, mirror or mirroring means flipping, so basically, the mirroring of a function is the mirror image of a given function or graph. Hence the reflection function is commonly known as the reflection function.
The reflection of the given function should be similar in size and shape to the original function.

A 28.5-Newton force is applied at a 30-degree angle to the horizontal to accelerate a 6.5-kg box across a rough surface (coefficient of friction = 0.22). Use g = 9.8 m/s/s to find frictional force (F(frict)) , normal force (F(norm)) , gravitational force (F(grav)) , and acceleration (a). Enter each answer accurate to the first decimal place.
Answer:
Frictional force (F(frict)) = 17.1 N
Normal force (F(norm)) = 78.0 N
Gravitational force (F(grav)) = 63.7 N
Acceleration (a) = 1.2 ms⁻²
Step-by-step explanation:
Newton's second law:
[tex]\boxed{F_{net}=ma}[/tex]
where:
[tex]F_{net}[/tex] = overall resultant force.m = mass.a = acceleration.Use trigonometry to resolve the 28.5 N force into its horizontal and vertical components since it is acting on the particle at 30°:
[tex]\implies F_x=28.5 \cos 30^{\circ}[/tex]
[tex]\implies F_y=28.5 \sin 30^{\circ}[/tex]
Weight (mg)Due to the particle's mass, m, and the acceleration due to gravity, g:
[tex]\boxed{W=mg}[/tex]
Given:
m = 6.5 kgg = 9.8 ms⁻²[tex]\begin{aligned}W & = mg\\\implies W & = 6.5 \times 9.8\\W & = 63.7\;\sf N\end{aligned}[/tex]
Normal reaction (R)The particle is moving parallel to the plane (the horizontal), so acceleration perpendicular to the plane is zero.
Resolving forces vertically (taking ↑ as positive):
[tex]\begin{aligned}F & = ma\\\implies R-W-28.5 \sin 30^{\circ}&=6.5 \times 0\\R-W-28.5 \sin 30^{\circ}&=0\\R & = W+28.5 \sin 30^{\circ}\\R & = 6.5(9.8)+28.5(0.5)\\R & = 63.7+14.25\\R & = 77.95\\R & = 78.0 \;\; \sf N\; (1\:d.p.)\end{aligned}[/tex]
Frictional force (F)When a moving object is acted on by a frictional force, fiction is limiting, and the frictional force F is at its maximum value:
[tex]\boxed{F = \mu R}[/tex]
(Where μ is the coefficient of friction and R is the normal reaction).
[tex]\begin{aligned}F & = \mu R\\\implies F & = 0.22 \times 77.95\\F & = 17.149\\F & = 17.1 \;\; \sf N\;(2\:d.p.)\end{aligned}[/tex]
Acceleration (a)Friction always acts in the opposite direction to motion (or potential motion).
Resolving forces horizontally (taking → as positive):
[tex]\begin{aligned}F & = ma\\\implies 28.5 \cos 30^{\circ}-F & = 6.5a\\28.5 \left(\dfrac{\sqrt{3}}{2}\right)-17.149 & = 6.5a\\\dfrac{57\sqrt{3}}{4}-17.149 & = 6.5a\\7.532724008 & = 6.5a\\a & = 1.158880617\\a & = 1.2\; \sf ms^{-2}\;\;(1\:d.p.)\end{aligned}[/tex]

What is the domain of the function shown in the graph below?
Answer Type:
Interval
All Real Numbers
All values except one
All values except two
The answer type is interval and the interval is (-∞,5).
The value of x is the domain for which the function is defined. Function in this case can use value from (-∞,5).
Graphs can be used to specify the domain and set of functions. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The range is the collection of potential output values, as displayed on the y-axis. Remember that the domain and range of the graph may be larger than the values seen if the graph extends beyond the area that is visible.
Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.
Hence, The type of answer is interval and the values of interval is (-∞,5).

Find following measure.
m GH
If m FH = (31x + 3°), m GH = (33x + 3°) and m ∠FHG = (28x − 3°) then the measure of ∠FGH is 48°.
How to find the measure of ∠FGH?Given: m FH = (31x + 3°), m GH = (33x + 3°) and m ∠FHG = (28x − 3°)
Based on the above information, we get
m FG = 2(m ∠FHG) = 2(28x - 3)°= (56x - 6)°
The arcs in the circle add up to 360 degrees, then
m FG + m FH + m GH = 360°
120x = 360°
x = 3
Substitute the value of x in m ∠FHG in we get
28(3) - 3 = 81°
The measure can be found using the triangle sum theorem (all angles in a triangle must add up to 180°).
Firstly, it is known that ∠GFH would be an inscribed angle if the chord from F to G is drawn, and the arc GH would be twice its measure.
m GH = 33(3) + 3 = 102°
Half of that would be m ∠GFH = 51°
According to the triangle sum theorem all angles of the triangle must add up to 180°:
Therefore, m ∠GFH+ m ∠FGH +m ∠FHG= 180°
m ∠FGH = 48°
Therefore, the measure of ∠FGH is 48°.
The complete question is:
Given: circle k(O), m FH = (31x + 3°) m GH = (33x + 3°)

The equation F = (9/5) C+32 relates temperatures on the Celsius and Fahrenheit scales. Does any temperature have the same number reading on both scales? If so, what is the number?
Both Fahrenheit and Celsius scales will have the same reading at temperature -40⁰.
The equation to convert temperature reading from Celsius to Fahrenheit degree is:
F = (9/5) C + 32
Where:
F = Fahrenheit reading
C = Celsius reading
The equation tells us that the ratio of increment in Fahrenheit to Celsius scale is 9 : 5, and there is an offset 32 degree in Fahrenheit scale.
Suppose a specific temperature has the same number reading on both scales, then:
F = C
Substitute this into the equation:
F = (9/5) C + 32
C = (9/5) C + 32
C - (9/5) C = 32
-4/5 C = 32
C = 32 . (-5/4) = -40
Hence, both Fahrenheit and Celsius scales have the same reading at temperature -40⁰.

In this problem, you will investigate the location of the points of concurrency for any equilateral triangle.
b. Verbal Make a conjecture about the relationships among the four points of concurrency of any equilateral triangle.
In an equilateral triangle, all the four points (circumcenter, incenter, orthocenter, and centroid) coincide.
What are the four points of concurrency for a triangle?The incenter is important for angle bisectors; the orthocenter is important for perpendicular bisectors; the circumcenter is important for altitudes; and the centroid is important for medians.
All four points (circumcenter, incenter, orthocenter, and centroid) of an equilateral triangle coincide.
The circumcenter is the point at which the perpendicular bisectors of all three sides of a triangle intersect. The circumcenter of an obtuse-angled triangle is located outside the triangle.
All four points of convergence can be concurrent. Only an equilateral triangle has the same centroid, circumcenter, incenter, and orthocenter at all times.
The 'orthocenter' is the point at which the altitudes of a triangle coincide. The orthocenter of a triangle is the point at which the triangle's three altitudes intersect.

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
5y-92x-4459
——————————— • 5 = 0 • 5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5y-92x-4459 = 0
Equation of a Straight Line
5.2 Solve 5y-92x-4459 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5y-92x-4459 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 4459/5 so this line "cuts" the y axis at y=891.80000
y-intercept = 4459/5 = 891.80000
Calculate the X-Intercept :
When y = 0 the value of x is 4459/-92 Our line therefore "cuts" the x axis at x=-48.46739
x-intercept = 4459/-92 = -48.46739
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 891.800 and for x=2.000, the value of y is 928.600. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 928.600 - 891.800 = 36.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 36.800/2.000 = 18.400
Geometric figure: Straight Line
Slope = 36.800/2.000 = 18.400
x-intercept = 4459/-92 = -48.46739
y-intercept = 4459/5 = 891.80000
