Factor out completly: 6x^2y − 3xy − 24xy^2 + 12y^2
---------------------------------------------------------------------
6x^2y − 3xy − 24xy^2 + 12y^2
Apply exponent rule:
6x^2y-3xy-24xyy+12yy
Rewrite 12 as 4*3
Rewrite -24 as 8*3
Rewrite 6 as 2*3
2*3x^2y-3xy+8*3xyy+4*3yy
Factor out common term 3y:
3y(2x^2-x-8xy+4y)

The factor of 6x²y − 3xy − 24xy² + 12y² is 3y(2x - 1)(x - 4y)
Given:
6x²y − 3xy − 24xy² + 12y²
find the highest common factor of all the coefficient of each term
6 = 1, 2, 3, 6
6 = 1, 2, 3, 63 = 1, 3
6 = 1, 2, 3, 63 = 1, 324 = 1, 2, 3, 4, 6, 8, 12, 24
6 = 1, 2, 3, 63 = 1, 324 = 1, 2, 3, 4, 6, 8, 12, 2412 = 1, 2, 3, 4, 6, 8, 12
The highest common factor of all the coefficient of each term is 3
So,
6x²y − 3xy − 24xy² + 12y²
= 3y(2x² - x - 8xy + 4y)
(2x² - x - 8xy + 4y) can also be factorised further(2x² - x - 8xy + 4y) = (2x - 1)(x - 4y)
Therefore,
6x²y − 3xy − 24xy² + 12y = 3y(2x - 1)(x - 4y)

What is cos θ if sin θ = −8/10 and θ is in Quadrant III?
Answer:
Drawing out the quadrants cos of an angle is negative in the third quadrant. Your drawing should indicate that x and y are negative. Then since we are working with a right triangle, again your diagram should indicate that. Determine the value of the third side. You know one is - 6 and the other opposite the 90 degree angle, the hypotenuse is 10. cos of an angle is adjacent divided by the hypotenuse.
I hope this helps if it did not help use this
cosine is negative in Quadrant III.
Use a pythagorean theorem to find the other leg. a2 = c2 - b2
adjacent leg = √(102 - 82)
cos θ = -6/10

To catch a frisbee, a dog leaps into air with an initial velocity of 14 feet per second. Write a model for the height of the dog above the ground. After how many seconds does the dog land on the ground?
Answer:
Model: [tex]y = 14t+\frac{1}{2}(32.16)t^{2}[/tex]
The dog land on the ground after 0.8706 seconds.
Step-by-step explanation:
The model that said the height of the dog above the ground is a model of uniform acceleration motion, so it is:
[tex]y = y_0+v_0t+\frac{1}{2}gt^{2}[/tex]
Where [tex]y_0[/tex] is the initial height, [tex]v_0[/tex] is the initial velocity and [tex]g[/tex] is the gravity.
So, replacing [tex]y_0[/tex] by zero, [tex]v_0[/tex] by 14 feet per second and [tex]g[/tex] by [tex]32.16 ft/s^2[/tex], we get that the model for the height of the dog above the ground is:
[tex]y = 14t+\frac{1}{2}(32.16)t^{2}[/tex]
Then, the time t when the dog land on the ground is calculated replacing [tex]y[/tex] by zero and solving for t as:
[tex]y = 14t+\frac{1}{2}(32.16)t^{2}\\0 = 14t+\frac{1}{2}(32.16)t^{2}\\0 =t (14 - 16.08t)[/tex]
Now, we have two possible solutions:
[tex]t=0[/tex] or [tex]14-16.08t=0[/tex]
Taking into account that t=0 is the time when the dog leaps into air, the time when the dog land on the ground is equal to 0.8706 seconds and it is calculated as:
[tex]14-16.08t=0\\14=16.08t\\\frac{14}{16.08}=t\\t=0.8706[/tex]

Find the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of π (no approximations).
!
Answer: 8 (Pi - sqrt(3))
Discussion:
The area of the shaded region is that of the semicircle minus the area of the triangle..
Area of semicircle = 1/2 * Pi * R^2
Where R^2 is the square of the radius of the circle. In our case, R ( = OC)
= 4 so the semicircle area is
(1/2) * Pi * (4^2) = (1/2) * Pi * 16 = 8 Pi
Area of triangle.
First of all, angle ACB is a right angle ( i.e. 90 degrees).
* This is the Theorem of Thales from elementary Plane Geometry. *
so by Pythagoras
AC^2 + BC^2 = AB^2
But CB = 4 (given) and AB = 4*2 = 8 ( the diameter is twice the radius).
Substituting these in Pythagoras gives
AC^2 + 4^2 = 8^2 or
AC^2 = 8^2 - 4^2- = 64 - 16 = 48
Hence AC = sqrt(48) = sqrt (16*3) = 4 * sqrt(3)
We are almost done! The area of the triangle is given by
(1/2) b * h = (1/2) BC * AC = (1/2) 4 * (4 * sqrt(3)) = 8 sqrt(3)
We conclude the area area of the shaded part is
8 PI - 8 sqrt(3) = 8 (Pi - sqrt(3))
Note that sqrt(3) is approx 1.7 so (PI - sqrt(3)) is a positive number, as it better well be!

After triangle ace is dilated by a factor of 5, it has an area of 100 square inches. What was its area before dilation?
Answer:
20in^2
Step-by-step explanation:
Since you multiply the original area of the triangle by the scale factor to get the new area, you can find the original area (before dilation) by dividing the dilated triangle's area by the scale factor. Since 100 is the area of the dilated triangle, and 5 is your scale factor, you do 100/5 to get the area of the triangle before it was dilated.

A polynomial function has a root of 5 with multiplicity 3, a root of 1 with multiplicity 2, and a root of 3 with multiplicity 7. If th
function has a negative leading coefficient and is of even degree, which statement about the graph is true?
O The graph of the function is positive on (-0, -5).
O The graph of the function is negative on (-5, 3)!
O The graph of the function is positive on (-0, 1).
O The graph of the function is negative on (3,co).
Answer:
The graph of the function is negative on (3,0)
Step-by-step explanation:
The limiting behavior of a function describes how a function behaves as x ⇒ ±∞. Its behavior is determined by the degree of a polynomial and the sign of its leading coefficient.
Since the function [f(x)] is an even degree polynomial with negative leading coefficient, then f(x) ⇒ -∞ as x ⇒ ±∞. The graph of the function is negative at the root. Since it has a root of 3, The graph of the function is negative on (3,0)
Answer:
The graph of the function is negative on (3, infinity) The answer is D

5. A metal ornament is being designed such that its perimeter is created by four identical three-quarter circles
as shown whose centers are connected to form a square. The ornament, both circular and square portions, is
made of wire that weighs 1.8 grams per inch. The square has sides that are 4 inches long.
(a) Determine the total length of the circular portions in terms of
pi. Show the work that leads to your answer.
(b) Determine the total length of wire needed, both circular and
square portions, to the nearest tenth of an inch.
G
(c) Determine the total weight of the ornament to the nearest
gram.
Answer:
(a) 12π in
(b) 53.5 in
(c) 96 grams
Step-by-step explanation:
In the figure attached, the ornament is shown
(a) four three-quarter circles is equivalent to 4*3/4 = 3 circles. The perimeter of a circle is the total length of the circular portions.
Perimeter of each circle: 2*π*r
The radius is 2 in long, then for 3 circles:
Perimeter = 3*2*π*2 = 12π in
(b) Perimeter of square: 4*side length
The side length of the square is 4 in, then:
Total length of wire needed = 4*4 + 12π = 53.5 in
(c) The wire weighs 1.8 grams per inch, then:
total weight of the ornament = 1.8 grams/in * 53.5 in = 96 grams
A shop is having a sale.
All items are reduced by 30%
Work out the sale price of an item normally priced at £110
Answer:
77
Step-by-step explanation:
10%=11
because you divide 110 by 10.
Then i would multiply that by 3, giving you 33
110-33=77
The sale price of an item normally priced at £110 is £77.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that all items are reduced by 30% on a sale.
An item that normally priced at £110 reduced by 30%.
So, 30 percentage of £110
= 30% of £110
= 110×30/100
= 3300/100
= 33.
Therefore, the sale price of an item normally priced at £110 is £77.

Answer:
Step-by-step explanation:
3a - 5 = -4b + 1
3a = -4b + 6
a = (-4b + 6)/3
h(a) = (-4b + 6)/3
Answer:
h(a) = [tex]\frac{6-3a}{4}[/tex]
Step-by-step explanation:
Given
3a - 5 = - 4b + 1
Rearrange making b the subject
Add 4b to both sides
4b + 3a - 5 = 1 ( add 5 to both sides )
4b + 3a = 6 ( subtract 3a from both sides )
4b = 6 - 3a ( divide both sides by 4 )
b = [tex]\frac{6-3a}{4}[/tex] , thus
h(a) = [tex]\frac{6-3a}{4}[/tex]
