Answer:
Part a: A square and a rhombus both have sides of equal length.
Let's calculate the length of each side.
[tex]\overline{PL}: \sqrt{(0-5)^2+(3-3)^2}=\sqrt{25+0}=5\\\overline{LA}\sqrt{(5-2)^2+(3-(-1))^2}=\sqrt{3^2+4^2}=5\\\overline{AN}:\sqrt{(2-(-3))^2+(-1-(-1))^2}=\sqrt{25+0}=5\\\overline{NP}:\sqrt{(-3-0)^2+(-1-3)^2}=\sqrt{3^2+4^2}=5[/tex]
All sides measure 5. So it's at least a rhombus (think of a square as a rhombus with extra restrictions).
Part b: A square has extra restriction, more important all angles being 90° and diagonals having the same length. If you discussed about slopes it's easy to see that two sides are horizontal but the other two are NOT vertical. Which might be proof enough.
But the exercise looks about lengths on the plane, so let's measure diagonals.
[tex]\overline{PA}=\sqrt{(0-2)^2+(3-(-1))^2}= \sqrt{2^2+4^2}=\sqrt{20}\\\overline{LN}=\sqrt{(5-(-3))^2+(3-(-1))^2}= \sqrt{8^2+4^2}=\sqrt{80}[/tex]
The two diagonals have different lengths, so the figure cannot be a square.

If a van traveled 240 miles in 4 hours, how far could the van travel in 5 hours?
Answers
Answer: i think 300
Step-by-step explanation: i divided 240 by 4 and got 60 then multiplied 60X5=300
Answer:
300 miles in five hours.
Step-by-step explanation:
speed = distance/time
distance = speed*time
240/4=60
d= 60*5
d=300 miles in five hours.
Word explanation:
You can use the formula, speed=distance/time to find the speed which is 60 mph. Now use the formula for distance which is distance= speed*time. The answer would be 300 miles in five hours.

The original price of the toaster is 2000
Step-by-step explanation:
Given: Toaster price = 2240
VAT = 12%
VAT amount = ?(I'll include this one)
Assume the original price be x.
Let the original price be x
Then, x + 12% of x = 2240
x+12/100x x = 2240
100x+12x/ 100= 2240
112x/100=2240
112x = 2240 x 100 ⇒ 224000
x = 224000/112
x = 2000.
So, the original price of toaster = Rs. 2000.
The VAT amount = 2240 - 2000 ⇒ Rs. 240.
The VAT amount is Rs. 240.

an artist is constructing a piece of art in the shape of rectangle. The artist wants to use string to tightly tie each vertex of rectangle to the other three vertices.

Answers
Answer:
An artist use 51.9 feet of string for constructing a piece of art in the shape of rectangle
Step-by-step explanation:
Here an artist is constructing a piece of art in the shape of rectangle having length 12 feet & width of 7 feet
Since the artist wants to use string to tightly tie each vertex of rectangle to the other three vertices. Hence one string will tie in a diagonal way
Hence total length of string will be
Total length = Perimeter of rectangle + length of diagonal
Perimeter of rectangle = 2( length + width ) = 2 ( 12 + 7 ) = 2 x 19 = 38 feet
Length of diagonal given by Pythagoras theorem
[tex]\mathrm{Length = { \left( { a }^{ 2 } + { b }^{ 2 } \right) }^{ 0.5 } = { \left( { 12 }^{ 2 } + { 7 }^{ 2 } \right) }^{ 0.5 } = 13.89244\:\:feet}[/tex]
Hence
Total length = Perimeter of rectangle + length of diagonal
Total length = 38 feet + 13.89244 feet = 51.9 feet
Hence an artist use 51.9 feet of string for constructing a piece of art in the shape of rectangle

5x^2 + 2 = 4x has no real solutions3x^2 + 24x = -48 has exactly one real solution3(x+5)^2 = -2 has no real solutions4x^2 - 16x = 0 has two real solutions======================================================
Explanation:
We can use the discriminant formula to determine how many (and what type of) roots we have. The term "root" is another word for "solution" or "x intercept". It's the x value that makes y = 0.
Any quadratic is of the form ax^2 + bx + c = 0
The discriminant formula is
d = b^2 - 4ac
which is found underneath the square root in the quadratic formula.
Here are the three possible outcomes
d > 0: we get two different real number solutionsd = 0: we have exactly one real number solutiond < 0: there are no real number solutions (the two solutions are complex or imaginary numbers).With all that in mind, let's find the discriminant of the first equation on the very left.
First we need to get it into standard form ax^2+bx+c = 0
5x^2 + 2 = 4x
5x^2 - 4x + 2 = 0
We see that
a = 5b = -4c = 2Computing the discriminant gets us...
d = b^2 - 4ac
d = (-4)^2 - 4(5)(2)
d = 16 - 40
d = -24
The actual discriminant value itself doesn't matter. All we care about is whether its positive, zero, or negative.
In this case, we get a negative discriminant. So this equation goes to the "no real solutions" column.
-------------------------
Let's move onto the next quadratic
3x^2 + 24x = -48
3x^2 + 24x + 48 = 0
a = 3, b = 24, c = 48
d = b^2 - 4ac
d = 24^2 - 4(3)(48)
d = 0
The discriminant of zero means this equation goes into the "exactly one real solution" category.
-------------------------
For the next equation, we don't need to use the discriminant formula here.
Notice that the right hand side is negative, but the left side is never negative because 3 is positive and (x+5)^2 is never negative. There is no way to have 3(x+5)^2 be negative if we let x be a real number only.
The equation 3(x+5)^2 = -2 goes into "no real solutions" pile.
-------------------------
For the last equation, we have
a = 4, b = -16, c = 0
So,
d = b^2 - 4ac
d = (-16)^2 - 4(4)(0)
d = 256
The result is a positive number, so we have two different solutions.
The discriminant is a perfect square which means we not only have real number solutions, but those solutions are rational numbers. This only works when a,b,c are rational as well.
