Answer:
The area of the polygon is 92.75 cm^2
Step-by-step explanation:
To find the area of the polygon, we simply add up the areas of the constituent triangles
At any point in time;
Area of a triangle = 1/2 * base * height
So we proceed as follows;
(1/2 * 12 * 4.5) + (1/2 * 12 * 5)
= 27 + 30 = 57 cm^2
There is a last triangle with 12 cm and 5 cm as the sides and we need the length of the hypotenuse
The length of the hypotenuse for that triangle will be 13 cm. This is because 5,12 and 13 are Pythagorean triple and they form the sides of a right-angled triangle
So for the last triangle, the area will be;
1/2 * 13 * 5.5 = 35.75 cm^2
So the total area is;
35.75 + 57 = 92.75 cm^2

24x = y^2-15y = x^228y = x^2-4x = y^28x = y^2-20y = x^2Step-by-step explanation:
There are two cases here. In one case, the focus has a non-zero x-coordinate, so the parabola opens left or right (depending on the sign). In the other case, the focus has a non-zero y-coordinate, so the parabola opens up or down (depending on the sign).
We can write the equations for each of the two cases.
For focus (a, 0), the equation can be written ...
4ax = y^2
For focus (0, a), the equation can be written ...

Please help me!! If the area of square 1 is 250 units2, and the area of square 3 is 120 units2, what is the area of square 2? Explain your reasoning.
Answers
Answer:
130units²
Step-by-step explanation:
The question lacks the required figure. Find the figure attached:
Given
Area of square 1 = 250units²
Area of square 3 = 120units²
Area of a square = L²
L is the length of one side of the square
Get the length of each side of the square
For square 1
A1 = L1²
250 = L1²
L1 = √250
Get that of square 3
A3 = L3²
120 = L3²
L3 = √120
Required
Area of square 2
Before we can get the area of square 2, we need to get the side length using pythagoras theorem
L₂² = L₁² - L₃²
L₂² = (√250)²-(√120)²
L₂² = 250-120
L₂² = 130
Since the area of the square A is L₂² , then the required area is 130units²

IX - 1l <4
Answers
Answer:
Here we can not see the options, so i will find the graph by the equation alone.
We start with:
Ix - 1I < 4
We could rewrite this as:
-4 < (x - 1) < 4
Now we can add 1 in the 3 parts, to get:
-4 + 1 < x - 1 + 1 < 4 + 1
-3 < x < 5
This means that the graph will be such that:
x > -3 (this is a dashed line at x = 3, and we shade the part in the right of that line)
and:
x < 5 (this is a dashed line at x = 5, and we shade the part in the left of that line)
The graph would look something like the one below
(If the graphs are only in one axis, you should see a white dot at x = -3, than a colour line that goes to the right until the point x = 5, where we have another white dot)

what is the distance between (-1, 2) and (3, 5)
Answers
Answer
the slope is 3/4 or .75
Answer:
The distance is 5 units.
Step-by-step explanation:
Key Skills needed for this problem: Distance Formula, Coordinate Plane Understanding, Radicals, Subtraction, Exponents, Addition
1) We are given 2 points --> (-1,2) and (3,5)
2) To find out the distance between both, we use distance formula.
This is: Given 2 points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], the distance between the 2 points would be: [tex]\sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}[/tex].
3) For the points (-1,2) and (3,5):
-1 is x12 is y13 is x25 is y24) Therefore it would be --> [tex]\sqrt{(-1 - 3)^{2} + (5-2)^{2}}[/tex]
5) This simplified would be [tex]\sqrt{(-4)^{2} + 3^{2}}[/tex]
6) This further simplified would be: [tex]\sqrt{16 + 9}[/tex]
7) This even more simplified would be [tex]\sqrt{25}[/tex] which is 5.
Therefore, the distance between the 2 points is 5 units.

He then cut this half that he had into 5 pieces of the same size.
The fraction of the sheet cake he has therefore is:

What is the slope of the line through the points (-4, 2) and (-16, -6)?
2/3
−5/2
2/5
3/2
Answers
Answer:
The slope is equal to [tex]\frac{2}{3}[/tex] . So the right answer is A.
Step-by-step explanation:
We know that if we are given to points of a function we can find out its slope by using the following formula....
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Where m is the slope, [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the coordinates of the first point, [tex]x_{2}[/tex] and [tex]y_{2}[/tex] are coordinates of the second point.
Let (-4, 2) be [tex](x_{1} , y_{1})[/tex]
Let (-16, - 6) be [tex](x_{2}, y_{2} )[/tex]
then......
The slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.
What is slope?Slope is or gradient of a line is a number that describes both the direction and the steepness of the line.
Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
We have,
Points (-4, 2) and (-16, -6)
i.e.
x₁ = -4, x₂ = -16,
And,
y₁ = 2, y₂ = -6
Now,
Using the above mentioned formula,
Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
i.e.
Slope [tex](m) =\frac{-6-2}{-16-(-4)}[/tex]
On solving we get,
Slope [tex](m) =\frac{-8}{-12}=\frac{2}{3}[/tex]
So, the slope pf the given points is [tex]\frac{2}{3}[/tex] .
Hence, we can say that the slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.
