Step-by-step explanation:
sin^2 x - 2sinx + 2 = sin^2 3x
Recall the triple angle identity for sine:
sin(3x) = 3 sin(x) cos²(x) - sin³(x)
… = 3 sin(x) (1 - sin²(x)) - sin³(x)
… = 3 sin(x) - 4 sin³(x)
So the equation is equivalent to
sin²(x) - 2 sin(x) + 2 = sin²(3x)
sin²(x) - 2 sin(x) + 2 = (3 sin(x) - 4 sin³(x))²
sin²(x) - 2 sin(x) + 2 = 9 sin²(x) - 24 sin⁴(x) + 16 sin⁶(x)
16 sin⁶(x) - 24 sin⁴(x) + 8 sin²(x) + 2 sin(x) - 2 = 0
or, by replacing y = sin(x),
16y ⁶ - 24y ⁴ + 8y ² + 2y - 2 = 0
By inspection, y = 1 is a root, since
16 - 24 + 8 + 2 - 2 = 0
so we get one family of solutions,
sin(x) = 1 ===> x = arcsin(1) + 2nπ = π/2 + 2nπ
Now suppose y ≠ 1. Dividing both sides of the sextic equation by y - 1 then gives
(16y ⁶ - 24y ⁴ + 8y ² + 2y - 2)/(y - 1) = 0
16y ⁵ + 16y ⁴ - 8y ³ - 8y ² + 2 = 0
Unfortunately, the remaining roots can only be obtained through numerical methods. Using a calculator, you would find
y ≈ -1.127
y ≈ -0.475 ± 0.368i
y ≈ 0.539 ± 0.127i
But if you're solving over the reals, you can ignore these solutions. Remember that sin(x) is bounded between -1 and 1, and its value goes outside this interval only when x is complex.
2) How would you simplify the following problem? (2x/3y^2)^3
Answer:

After substitute y=25. we get,
x

−22x+121−25=0
⇒x

−22x+96=0
⇒(x−16)(x−6)=0
⇒x=16,x=6
∴ two points are A,B are (16,25),(6,25).
Distance between A and B is

A class is having a water balloon tossing contest. There is a large tub of water. Gavin uses 3 1/5 quarts of water to fill some balloons, and Quinley uses 6 1/2 quarts to fill more balloons. Find the total change of volume of water in the tub
We want to find the total change in the volume of water of a tub, given that we know how much water is used.
The change in volume is: -(9 + 7/10) quarts.
To find the change in volume, we need to find the total volume of water used.
We do know that:
Gavin uses (3 + 1/5) quarts of waterQuinley uses (6 + 1/2) quarts of water.The total amount used is the sum of the two quantities above, we get:
(3 + 1/5) quarts + (6 + 1/2) quarts
(3 + 6 + 1/2 + 1/5) quarts
(9 + 7/10) quarts.
So the change in volume is related to this, and we should write:
Final Volume - Initial Volume = -(9 + 7/10) quarts.
Where the negative sign is because at the end we have less volume than at the beginning.

The theater sells two types of tickets: adult tickets for $14 and child tickets for $8.
Last night, the theater sold a total of 159 tickets for a total of $1794. How many adult tickets did the theater sell last night?
Answer:
87 Adult tickets were sold
Step-by-step explanation:
This type of question relates to a system of equations. These types of questions are pretty easy to spot and they are just about solved all the same way.
So what we first want to do is see that there is a total of 159 tickets sold. Now obviously that number consists of the adult and children tickets, therefore we need to add those two unknown numbers to get 159, so x will be for adults and y will be for children tickets. this will give us the equation x + y= 159.
Next, we want to associate the amount those tickets are with those variables, because you can only have so many adult tickets and children tickets with the given $1794. So what we need to do is similar, we just have those totals added to get the equation 14x + 8y = 1794.
Now we want to use the process of elimination to find the value of x (because we are solving how many adult tickets were sold). IN order to do elimination, we need to have the equation x + y= 159 cancel the y value to leave us with the x value. In order to do this, you need to multiply y by a value that cancels 8y in 14x + 8y = 1794, which is -8.
So we multiply the entire equation of x + y= 159 by -8 to get. Now we would add these equations together where you subtract by like terms so:
[tex]14x + 8y = 1794\\-8x - 8y = -1272[/tex]
This leaves us with 6x=522 now you would divide by 6 to isolate x which leaves you with 87.

a & b are the sides
c is hypotenuse

A rectangular field is five times as long as wide. If the perimeter of the field is 780 feet, what are the dimensions of the field?
Answer:
65 and 325
Step-by-step explanation:
(l+w)*2 = 780
l+w = 390
l = 5w
5w + w = 390
6w = 390
w = 65
length = 325
Q and R are complementary. The measure of Q is 26 less than the measure of R. Find the measure of each angle
Step-by-step explanation:
Since Q and R are complementary,
⇒ Q + R = 90°
Since Q is 26° less than the measure of R
⇒ R - 26° = Q
We can therefore say that ( R - 26°) + R = 90°
⇒ 2 R = 90° + 26°
R = 58 °
Also, since R - 26° = Q
58° - 26° = Q
32 ° = Q
∴ Q = 32 ° and R = 58°round 88.85 to the nearest ten

To make papier-mâché, Emma uses 3/4 cup of white school glue for each batch. For a big project, she will make 11 batches of papier-mâché. Emma has half of 1-gallon bottle of white school glue. Does Emma have enough glue?
Emma will not have enough glue since she'll have 10 2/3 rather than 11 batches.
Note that 1 gallon = 16 cups
Since Emma has half of 1-gallon bottle of white school glue, this means that she has 1/2 × 16 = 8 cups
Since Emma uses 3/4 cup of white school glue for each batch, therefore the number of batches that van be made with 8 cups will be:
= 8 ÷ 3/4
= 8 × 4/3
= 10 2/3
Therefore, Emma will not have enough glue since she'll have 10 2/3 rather than 11 batches.
