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].

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.

Me ajudemmm é pra hoje!!! Escreva como produto entre um número natural e uma potência de base 10. a) 300 b)4.000 c)50 000 d)700.000
Responder:
3 * 10²
4 * 10³
5 * 10⁴
7 * 10 ^ 5
Explicação passo a passo:
Expressando o seguinte como um produto de um número natural e uma potência base de 10.
Lembrar :
10 = 10¹
100 = 10 * 10 = 10²
1000 = 10 * 10 * 10 = 10³
Portanto,
300 = 3 * 100 = 3 * (10 * 10) = 3 * 10²
4000 = 4 * 1000 = 4 * (10 * 10 * 10) = 4 * 10³
50000 = 5 * 10000 = 5 * (10 * 10 * 10 * 10) = 5 * 10⁴
700000 = 7 * 100000 = 7 * (10 * 10 * 10 * 10 * 10) = 7 * 10 ^ 5

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the number 5
Answer:
1/18
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
Multiples of 3 between 1 - 9 = 3,6,9
Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag
3/9
To transform to the simplest form. divide both the numerator and the denominator by 3
1/3
After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6
Probability of picking 5 = 1/6
1/6 x 1/3 = 1/18
Of the fifth graders in oak elementary, 6/8 are in band. What fraction of the fifth graders are not in band?
Answer:
2/8 of the fifth graders are not in band
Step-by-step explanation:
To find how many fifth graders are not in band, subtract the # of fifth graders in band. Your difference is the amount of fifth graders that are not in band. To check your answer add 2/8 + 6/8 which should be equal to 8/8 or a whole ( 1 ).

2) A block of cheese weighs 0.6 kg. The block is cut into smaller pieces. Each piece weighs 0.05 kg. How many pieces are there? (Show the division equation to solve for this word problem before showing multiplication to solve.)
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)
= 60/5 = 12

Step-by-step explanation:
cm to inches: 0.3937007874 to 1
the side edges are 3.937007874
Since it's a square pryramid, all of the side lengths are equal. 3.937007874^2 is 15.500031.
The formula for a pyramid: base*height/3
15.500031*12/3 = 62.000124 in. cubed
The funnel is filled with oil. How many quarts of oil are in the funnel? 3 1 qt 58 in. Round your answer to the nearest tenth.
Answer:
There is 2.887 quarts of oil in the funnel
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
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?
