Answer:
Step-by-step explanation:
Take a triangle ABC, in which AB=AC.
Construct AP bisector of angle A meeting BC at P.
In ∆ABP and ∆ACP
AP=AP[common]
AB=AC[given]
angle BAP=angle CAP[by construction]
Therefore, ∆ABP congurent ∆ACP[S.A.S]
This implies, angle ABP=angleACP[C.P.C.T]

Is the line through points P(3, –5) and Q(1, 4) parallel to the line through points R(–1, 1) and S(3, –3)? Explain. a No; the lines have unequal slopes. b Yes; the lines have equal slopes. c No; one line has zero slope, the other has no slope. d Yes; the lines are both vertical.
Answer:
3
Step-by-step explanation:
The Answer would be Option A) No, the lines have unequal slopes.
What is the slope of a line which passes through points ( p,q) and (x,y)?Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
Slope of first line,
[tex]m = \dfrac{y-q}{x-p}\\\\m = \dfrac{4-(-5)}{1-3}\\\\m = \dfrac{9}{-2}[/tex]
Slope of second line,
[tex]n = \dfrac{y-q}{x-p}\\\\n = \dfrac{-3-1}{3-(-1)}\\\\n = -1[/tex]
Thus, The Answer would be Option A) No, the lines have unequal slopes.

5x + 6 = 46. Is x = 8 a solution for this equation? Justify your answer by
showing your step with explanation.
Answer:
x = 8Step-by-step explanation:
5x + 6 = 46. Is x = 8
5x + 6 = 46
subtract 6 to each side
5x + 6 - 6 = 46 - 6
simplify:
5x = 46 - 6
divide 5 both sides
x = 40 / 5
simplify:
x = 8
Answer:
Yes.
Step-by-step explanation:
[tex]5x+6=46[/tex]
To check to see if x = 8 is a solution, replace 'x' with 8 and evaluate.
[tex]5(8)+6=46\\\\40+6=46\\\\\boxed{46=46}[/tex]
We get a true statement. This means that x = 8 is a solution to the equation.

m= -4 contains (0,3)
explain the work plz
Answer:
y -3 = -4(x -0) or y -3 = -4xy = -4x +3Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
Fill in the given values:
y -3 = -4(x -0) . . . . point-slope form of the equation of the line

What is significance of function in real life situation?
Answer:
functions are the foundation of the modern world view
Step-by-step explanation:
It has been said that "Insanity is doing the same thing over and over again and expecting different results." A functional relationship ensures that any given input will always result in the same output. That is a relationship that is not a function, where the same input can give different outputs, is equivalent to insanity.
Virtually all of modern science is predicated on the assumption that same inputs produce same outputs. In cases where that does not happen, we attribute the different outputs to inputs that have not yet been identified. In short, functional relationships are the foundation of our view of the world.
write an equation in point slope form of the line that passes through the point (-3,6) and has a slope of 5
Answer:
y=5x+6
Step-by-step explanation:
use the equation y=mx+b
m=slope and b=y-intercept
You can go ahead and insert 5 into the equation because we know that the slope of the line is 5. for b. the y-intercept, we know that points are in (x,y) form so we can infer that -3 is the x and 6 is the y. from here you can plug in the number 6 for b and there's your equation. hope this helps!!

What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
The given point and slopes are (-3, 6) and 5 respectively.
The equation of the line can be written by plugging all the values in y = mx + c as follows,
6 = -3 × 5 + c
⇒ c = 21

Answer:
All results in the explanation
Step-by-step explanation:
To make the equation of the line, we only need two points. Select from the table the points (-1,4) and (3,9).
First, find the slope of the line:
We know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
\begin{gathered}\displaystyle m=\frac{y_2-y_1}{x_2-x_1}\\\end{gathered}m=x2−x1y2−y1
Substituting:
\displaystyle m=\frac{9-4}{3+1}=\frac{5}{4}m=3+19−4=45
This value is used in the slope-point form of the line:
\displaystyle y-k=\frac{5}{4}(x-h)y−k=45(x−h)
Where (h,k) is a point from the table, select for example (3,9):
\displaystyle y-9=\frac{5}{4}(x-3)y−9=45(x−3)
Operate:
\displaystyle y=\frac{5}{4}\cdot x-\frac{5}{4}\cdot 3+9y=45⋅x−45⋅3+9
\displaystyle y=\frac{5}{4}\cdot x+\frac{-15+36}{4}y=45⋅x+4−15+36
The equation of the line is:
\boxed{\displaystyle y=\frac{5}{4}\cdot x+\frac{21}{4}}y=45⋅x+421
Now complete the table.
For x=0:
\displaystyle y=\frac{5}{4}\cdot 0+\frac{21}{4}y=45⋅0+421
y=\frac{21}{4}y=421
For x=15
\displaystyle y=\frac{5}{4}\cdot 15+\frac{21}{4}y=45⋅15+421
\displaystyle y=\frac{75}{4}+\frac{21}{4}=\frac{96}{4}=24y=475+421=496=24
y=24
For y=1.5, find x:
\displaystyle 1.5=\frac{5}{4}\cdot x+\frac{21}{4}1.5=45⋅x+421
Operate:
\displaystyle 1.5-\frac{21}{4}=\frac{5}{4}\cdot x1.5−421=45⋅x
Multiply by 4:
\displaystyle 6-21=5 x6−21=5x
Solve:
x=-15/5=-3x=−15/5=−3
x=-3

If 5-y^2=x^2 then find d^2y/dx^2 at the point (2, 1) in simplest form.
Answer:
y"(2, 1) = -5
Step-by-step explanation:
Step 1: Define implicit differentiation
5 - y² = x²
Step 2: Find dy/dx
Take implicit differentiation: -2yy' = 2xIsolate y': y' = 2x/-2yIsolate y': y' = -x/yStep 3: Find d²y/dx²
Quotient Rule: y'' = [y(-1) - y'(-x)] / y²Substitute y': y" = [-y - (-x/y)(-x)] / y²Simplify: y" = [-y - x²/y] / y²Multiply top/bottom by y: y" = (-y² - x²) / y³Factor negative: y" = -(y² + x²) / y³Step 4: Substitute and Evaluate
y"(2, 1) = -(1² + 2²) / 1³
y"(2, 1) = -(1 + 4) / 1
y"(2, 1) = -5/1
y"(2, 1) = -5

Answer:
x = 4°
Step-by-step explanation:
10x+2°+62° = 25x+4°{ the exterior angle formed by producing the side of triangle is equal to two non-adjacent angle}
or, 10x + 64° = 25x+4°
or, 10x-25x = 4°-64°
or, -15x = -60°
or, x = -60°/-15

A race track is made from two straights and two semicircles. The straights are 80m long. The race track has a total perimeter of 400m.
Calculate the distance,d, between the two straights.
Answer:
76.4 m
Step-by-step explanation:
The race track has two straights and two semi circles.
Each straight is 80m
total perimeter for the straights is 80 * 2 = 160m
two semi circles which creates a full circle
perimeter of a full circle = [tex]\pi[/tex] d
NB : (d) is the diameter
therefore we can find the value of the diameter
400 = 160 + [tex]\pi[/tex] d
400- 160 = [tex]\pi[/tex]d
240 = [tex]\pi[/tex]d
d = 240/[tex]\pi[/tex]
d = 76.394.....
d = 76.4 m

Answer:
First find the angle next to 110 °
110+?=180 (linear pair)
? = 180-110
? = 70
Since the triangle is isosceles, the bottom two angles are 70 °.
Now, to find x....
All interior angles of a triangle equals 180°.
180 = 70+70+x
180 = 140+x
x = 180-140
x = 40

At the South Gwinnett High School game, 35 out of 50 people entered with a mask on, without being reminded at the door. If this sample is representative of the 250 people attending the game, about how many of them will probably be wearing a mask without being reminded?
Answer:
175 people
Step-by-step explanation:
In order to calculate this, we first need to find out what percentage 35 out of 50 people actually represents. We do this by dividing 35 by 50 and then multiplying that decimal by 100% to turn it into a percentage like so...
35 / 50 = 0.70
0.70 * 100 = 70%
Now we know that 70 percent of the individuals did not have to be reminded of wearing a mask. If this percentage or ratio remains constant, then we can simply multiply the number of people at the game by this percentage in decimal format in order to calculate the total amount of people that will probably be wearing a mask.
250 * 0.70 = 175 people
There should be a total of 175 people wearing a mask without being reminded.
