What is trigonometry identity?
When trigonometric functions are used in an expression or equation, trigonometric Identities come in handy.
One of the trigonometry identity is [tex]\cos2x=2\cos^{2} x-1[/tex].
What is the simplified expression for given expression?
In the given expression [tex]\cos6x[/tex] can be break as [tex]\cos(2\cdot3x)[/tex].
Now use the identity [tex]\cos2x=2\cos^{2} x-1[/tex] in the given expression.
[tex]1-\cos6x=1-2\cos^{2}{3x}+1[/tex]
[tex]=2(1-\cos^{2}{3x})[/tex]
Now use the identity [tex]1-\cos^{2}x=\sin^{2}x[/tex].
[tex]1-\cos6x=2\sin^{2}{3x}[/tex].
Therefore, the given expression is equivalent to [tex]2\sin^{2}{3x}[/tex].

Step-by-step explanation:
What is the root when talking about a quadratic equation
The root is the x intercepts or the zeros of the problem
If I were to graph
(x-5)(x+4)=0
We need a number for x which makes this equation 0
The numbers are 5 or -4
These are the x intercepts of the parabola or roots
Answer:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Step-by-step explanation:
Choose an equivalent system of equations to the following system:
Fx + Gy = H
Qx + Ry = S
6Fx + Gy = 6H
Qx + 6Ry = S
6Fx + 6Gy = 6H
Qx + Ry = S
Fx + 6Gy = 6H
Qx + Ry = S
6Fx + 6Gy = 6H
Qx − Ry = S
Answer:
B. 6Fx + 6Gy = 6H
Qx + Ry = S
Step-by-step explanation:
Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.
_____
Comments on other choices
A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.
B: the correct choice
C: see A.
D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.
Answer:
6Fx + 6Gy = 6H
Qx + Ry = S

A new truck sells for $29,000 and depreciates 12% each year. Find the value of the truck after 10 years.
Answer:
according to the question value got less 12% each year
first of all the 12% of 29000$ = 29000÷100×12= 3480 $
in one year truck value deprecates 3480$
in 10 years it will 3480$×10 =34800$

Step-by-step explanation:
Complete question
A funnel is in the shape of a cone with a radius of 4 inches and a height of
10 inches. The funnel is filled with oil. How many quarts of oil are in the funnel?
Solution
As we know, volume of the cone is given by
[tex]V = \frac{1}{3} \pi r^2 h[/tex]
Here,
V = volume of the cone
r is the radius of the base of the cone
h is the height of the cone
Substituting the given values in above equation, we get -
[tex]V = \frac{1}{3} *3.14*4*4*10\\V = 167.467[/tex] Cubic inch
As given
1 quarts = 58 cubic inch
Total number of quarts of oil
[tex]\frac{167.467}{58} \\2.887[/tex]
There is 2.887 quarts of oil in the funnel

A video game originally costs $63, but if you buy it before the end of May there is a 25% off sale. The sales tax is 9.5%. What is the final price of the video game if you buy it before the end of May?
Answer: $53.24
Step-by-step explanation:
Find the sales tax:
9.5*63.00=598.5
Then divide 598.5 by 100: 598.5/100= 5.985
Round: $5.99 ( sale tax amount )
Now we find the discount: 25*63.00= 1,575
Then divide it by 100 : 1,575/100= $15.75 ( discount amount )
Take the original price of the game and subtract it by the discount amount, then add the sales tax amount: 63.00-15.75= 47.25+5.99= $53.24
Answer: $53.24

Find the perimeter of a rectangle with length (x-5) and width (3x+1).
Answer:
8x-8
Step-by-step explanation:
P=s+s+s+s or in this case P= 2l+2w
P= 2(x-5)+2(3x+1)
P=(2x-10)+(6x+2)
P=8x-8
8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1).
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given that,
Length of rectangle = x - 5
Width of rectangle = 3x + 1
Now,
Perimeter of rectangle = 2(width + length)
Perimeter of rectangle = 2(3x + 1 + x - 5)
The perimeter of the rectangle = 8x - 8
Hence "8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1)".

Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06. Using = 0.10, what conclusion should Devon reach?

Answer:
12
0.6/0.05
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12
Step-by-step explanation:
number of pieces = total weight of the cheese / weight of each piece
0.6 / 0.05
to divide easily, convert the decimals to whole number by multiply both the denominator and numerator by 100
(0.6 x 100) / (0.05 x 100)

44+2W=74
Subtract 44 from both sides
2W=30
Divide both sides by 2
