3. Consider the straight line x + y = 1 and the family of straight lines that pass
through the origin given by y = mx. As m changes the line rotates about the
origin. Solve these two systems of linear equation and find their points of inter-
section. Is there always a solution - If yes, briefly explain why. If not - for what
a
values of m is there no solution.
Answer:
solution: (1/(1+m), m/(1+m))no solution for m = -1 (lines are parallel)Step-by-step explanation:
Two distinct lines will always have a point of intersection, provided they are not parallel. That is, the system of equations {x +y = 1, y = mx} will have a unique solution as long as m ≠ -1.
The solution to the system can be found by substitution:
x +mx = 1
x(1 +m) = 1 . . . . factor out x
x = 1/(1+m) . . . . . divide by the coefficient of x; we must have m ≠ -1
y = m/(1+m) . . . . find the y-coordinate of the solution
The point of intersection is (1/(1+m), m/(1+m)).
__
The above solution is undefined when the denominator is zero: m = -1. There is no solution for m = -1.
Find the area of the polygon
Answer:
Area of a regular polygon formulas
Step-by-step explanation:
area = n * a * ri / 2 , having ri - incircle radius (it's also an apothem - a line segment from the center to the midpoint of one of its sides)
area = perimeter * ri / 2 , given ri and polygon perimeter.
area = n * (ri)² * tan(π/n) , given ri.

Answer:
39 sq.in
Step-by-step explanation:
find area of circle then subtract
Answer:
3.9 in²
Step-by-step explanation:
The shape is constructed of 2 semicircles (with diameter of 6 in) inside a square. Therefore, to calculate the yellow region, subtract the area of the semicircles (which form a circle) from the area of the square, then halve the answer.
Area of a square = [tex]x^2[/tex] ([tex]x[/tex] is the length of one side)
Given:
side length = 6 in⇒ area of the square = 6² = 36 in ²
Area of a circle = [tex]\pi r^2[/tex]
Diameter of a circle = 2r
(where r is the radius)
Given:
diameter = 6 in ⇒ r = 3 in⇒ area of the circle = [tex]\pi[/tex] × 3² = 9[tex]\pi[/tex] in²
Area of yellow region = (area of square - area of circle) ÷ 2
= (36 - 9[tex]\pi[/tex]) ÷ 2
= 3.9 in² (nearest tenth)

Using the interquartile range, which of the following are outliers? Select all correct answers.
Select all that apply:
3
6
21
60
Answer:
3 and 6
Step-by-step explanation:
IQR = Q3-Q1=96-62=34
Lower Outlier = Q1 - 1.5*IQR = 62 - 1.5*34 = 11
Any Value under 11 is Considered as Outlier
Then 3 and 6 are Outliers
Upper Outlier = Q3 + 1.5*IQR = 96 + 1.5*34 = 147
Any Value Above 147 is Considered as Outlier
There is no Value above 147
The Only Outliers are 3 and 6

The circumference of a circle with radius 48 is 301.6(*)
Step-by-step explanation:
Formulas:
d = 96C = 302C = 2·π·r C = π·d C = √4·π·A π = 3.1415A = area of the circleC = circumference or perimeterr = radius, d = diameterStep-by-step Solution:
Circumference of a cicle in terms of radius:Circumference = 2·π·r = 2·3.14·48 = 301.58(*)In terms of diameter:Circumference = π·d = 3.14·96 = 301.44(*)In terms of area:Circumference C = √4·π·A = √4·π·7238 = 301.58(*)(*) 301.6 cm exactly or limited to de precision of this calculator (13 decimal places).

A triangle has side lengths of 54, 72 & 90. Is it a right triangle? Explain.
No, there always has to be an odd number for it to work out to be a right triangle.
No, it is obtuse.
No, it is acute.
Yes, the Pythagorean Theorem works out to be equal.
Yes, because 52 + 72 > 90.
Answer: C: Yes, the Pythagorean Theorem works out to be equal.
Step-by-step explanation:
to test if a triangle is right angled or not, just use the Pythagorean Theorem:
a²+b²=c², where a and b are the two shorter sides of the triangle, and c is the longest side.
plugging this in:
54²+72² ?= 90²
2916 + 5184 ?= 8100
8100 = 8100
Yes! Its correct, so we know that this triangle is a right triangle. the justification is C: Yes, the Pythagorean Theorem works out to be equal.

Aaliyah is a salesperson who sells computers at an electronics store. She makes a base pay of $70 each day and then is paid a $1.25 commission for every computer sale she makes. Write an equation for P,P, in terms of x,x, representing Aaliyah's total pay on a day on which she sells xx computers.
Answer:
p = 1.25x + 70
Step-by-step explanation:
We know she makes $70 each day and we know she makes $1.25 for each computer she sells.
With that we can add it into an equation because we can add 70 + 1.25, but the amount for each computer she sells in unknown so we give it an x which makes it 1.25x.
So, we do 1.25x + 70, but the amount total is missing so that is our p.
This finally completes our equation, p = 1.25x + 70 or 1.25x + 70 = p

if the sides of a triangle QRS are QR=10X-6, RS=6X-15,QS=X+24, find a range of possible values for X?
The range of the possible values for X will be;
⇒ X < 5
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The sides of a triangle QRS are;
⇒ QR=10X - 6,
⇒ RS = 6X - 15,
⇒ QS = X + 24,
Now,
We know that;
The sum of two sides of a triangle is always greater than the third side.
So, We can formulate;
⇒ 10X - 6 < (6X - 15) + (X + 24)
⇒ 10X - 6 < 7X + 9
⇒ 10X - 7X < 9 + 6
⇒ 3X < 15
⇒ X < 5
Thus, The range of the possible values for X will be;
⇒ X < 5

A promissory note for $3600.00 dated May 15, 2012, requires an interest payment of $370.00 at maturity. If interest is at 9.6% compounded monthly, determine the due date of the note. (hint: find n then convert it into days and use excel sheet to add it to issue date)
In the box below show these parameters:
PV=....., FV=.....
The due date of the promissory note is May 24th 2013.
Data;
Present Value (PV) = $3600Interest = $370Future Value (FV) = PV + I = $3600 + $370 = $3970Due Date of the NoteTo calculate the due date of the note, we can use the formula of future value of the note.
[tex]FV = PV (1 + \frac{r}{n})^d\\ 3970 = 3600 (1 + \frac{9.6}{12})^d\\3970 = 3600(1+0.008)^d\\\frac{3970}{3600} =(1.008)^n[/tex]

the smiths spend 11% of their budget on entertainment. their total budget this year is $1,000 more than last year, and this year they plan to spend $4,620 on entertainment. what was their total budget last year?
Answer: $41000 Was the Smiths family budget last year.
Step-by-step explanation:
First you take $4620 and DIVIDE it by .11 you will get $42000 and since last year had $1000 less to spend you subtract $1000 from $42000 to get $41000 for the budget last year.

Consider the line y=9x-5. Find the equation of the line that is perpendicular to that line and passes through the point (-3,-3)
Answer:
y=(-1/9)x-(10/3)
Step-by-step explanation:
Since the line is perpendicular to y=9x-5, the slope of that line would be the opposite of the reciprocal of the original slope value. In this case, the slope of the line would be -1/9. So we have y=(-1/9)x+? Since we know a point, (-3, -3), we can input this back into our original equation and we have: -3=(1/3)+? We simplify and we have ?=-10/3. Therefore the final equation of the line that is perpendicular to that line and passes through the point (-3,-3) is y=(-1/9)x-(10/3).
