Answer:
[tex] \displaystyle \theta = - {41.8}^{ \circ} + 2n\pi, {210}^{ \circ} + 2n\pi , {221.8}^{ \circ} +2nπ , {330}^{ \circ} +2nπ [/tex]
Step-by-step explanation:
we would like to solve the following trigonometric equation:
[tex] \displaystyle 6 { \sin}^{2} ( \theta) + 7 \sin( \theta) + 2 = 0[/tex]
to do so we can let sinθ be u so it'll be easier to solve:
[tex] \displaystyle 6 { u}^{2} + 7 u + 2 = 0[/tex]
to notice is that it's a quadratic equation to solve the equation we can consider factoring method in this method we rewrite the middle term as sum or substraction of two different terms in that case 3u+4u can be mentioned:
[tex] \displaystyle 6 { u}^{2} +3u + 4u + 2 = 0[/tex]
(continuing the method) well we can factor out the common terms and that yields:
[tex] \displaystyle 3u(2 { u}^{} +1) + 2(2u + 1)= 0[/tex]
group:
[tex] \displaystyle (3u+ 2)(2u + 1)= 0[/tex]
by Zero product property we acquire:
[tex] \begin{cases}\displaystyle 3u+ 2 = 0 \\ 2u + 1= 0 \end{cases}[/tex]
solve the equation for u:
[tex] \begin{cases}\displaystyle u = - \frac{2}{3} \\ \\ u= - \dfrac{1}{2} \end{cases}[/tex]
substitute back:
[tex] \begin{cases}\displaystyle \sin( \theta) = - \frac{2}{3} \\ \\ \sin( \theta) = - \dfrac{1}{2} \end{cases}[/tex]
take inverse trig in both sides and that yields:
[tex] \begin{cases}\displaystyle \theta = - {41.8}^{ \circ}, {221.8}^{ \circ} \\ \\ \theta = {210}^{ \circ} , {330}^{ \circ} \end{cases}[/tex]
add period of 2nπ:
[tex] \displaystyle \theta = - {41.8}^{ \circ} + 2n\pi, {210}^{ \circ} + 2n\pi , {221.8}^{ \circ} +2nπ , {330}^{ \circ} +2nπ [/tex]

A company rents water tanks shaped like cylinders. Each tank has a radius of 6 feet and a height of 2 feet. The cost is $30 per cubic foot. How much does it cost to rent one water tank
Step-by-step explanation:
Volume of tank = (pi)×(radius squared)×(height)
= 3.14×(6×6)×2
= 3.14×36×2
= 226.08 cu.ft
Each cu.ft is rented for $30
So, for 226.08 cu.ft is,

Answer:
theta = 30 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side/ hypotenuse
sin theta = 25/50
sin theta = 1/2
Taking the inverse sin of each side
sin ^-1 (sin theta) = sin ^-1 (1/2)
theta = sin ^-1 (1/2)
theta = 30 degrees
A bag contains 7 red cubes, 3 yellow cubes, 2 green cubes, and 4 blue cubes. One cube is selected at
random from the bag. What is the probability that the selected cube will NOT be blue?
1/4
5/8
3/4
7/8
Answer:
3/4
Step-by-step explanation:
7 + 3 + 2 + 4 = 16
4 blue cubes = 4/16
16 - 4 = 12
12/16 = 6/8 = 3/4
The probability that the selected cube will not be blue is 3/4.
How to calculate probability?Total number of cubes: 7+3+2+4=16
Number of cubes that are not blue: 12
Probability: Desired outcomes/ Total outcomes
=12/16
=3/4
Therefore, the probability of not selecting blue cube is 75%(or 3/4).

Plug in the value of x = 3 for every equation
I plugged the value of 3 into this equation:
2(3) +3y = 0
3 + 2y = -1
Let's start with the first line
6 + 3y = 0
-6 -6
3y = -6
3y/3 = -6/3
y = -2
Now let's solve the second line
3 +2y = -1
-3 -3
2y = -4
2y/2 = -4/2
y=-2
Since both equations have the solution y = -2, that means the system of equations is valid when the value of x is 3.

Given a leading coefficient of 8, polynomial roots of 1 & 2, and the known point on the graph (4,5). Write an equation that will find the
missing 3rd root (r). You do not have to solve the problem. See the example "Find the Missing Root - Interesting Twist" if you need help.
_=_(_-1)(_-2)(_-_)
Given:
The leading coefficient of a polynomial is 8.
Polynomial roots are 1 and 2.
The graph passes through the point (4,5).
To find:
The 3rd root and the equation of the polynomial.
Solution:
The factor form of a polynomial is:
[tex]y=a(x-c_1)(x-c_2)...(x-c_n)[/tex]
Where, a is a constant and [tex]c_1,c_2,...,c_n[/tex] are the roots of the polynomial.
Polynomial roots are 1 and 2. So, [tex](x-1)[/tex] and [tex](x-2)[/tex] are the factors of the polynomial.
Let the third root of the polynomial by c, then [tex](x-c)[/tex] is a factor of the polynomial.
The leading coefficient of a polynomial is 8. So, a=8 and the equation of the polynomial is:
[tex]y=8(x-1)(x-2)(x-c)[/tex]
The graph passes through the point (4,5). Putting [tex]x=4,y=5[/tex], we get
[tex]5=8(4-1)(4-2)(4-c)[/tex]
[tex]5=8(3)(2)(4-c)[/tex]
[tex]5=48(4-c)[/tex]
Divide both sides by 48.
[tex]\dfrac{5}{48}=4-c[/tex]
[tex]c=4-\dfrac{5}{48}[/tex]
[tex]c=\dfrac{192-5}{48}[/tex]
[tex]c=\dfrac{187}{48}[/tex]
Therefore, the 3rd root on the polynomial is [tex]\dfrac{187}{48}[/tex].
In △ABC, m∠A=50∘, m∠B=60∘, and m∠C=70∘.

Given:
In [tex]\Delta ABC, m\angle A=50^\circ, m\angle B=60^\circ[/tex] and [tex]m\angle C=70^\circ[/tex].
[tex]\Delta ABC[/tex] is rotated [tex]90^\circ[/tex] counterclockwise to [tex]\Delta XYZ[/tex].
To find:
The measure of angle Z.
Solution:
We know that the rotation is a rigid transformation. It means the image and figure are congruent to each other.
[tex]\Delta ABC[/tex] is rotated [tex]90^\circ[/tex] counterclockwise to [tex]\Delta XYZ[/tex]. So, [tex]\Delta ABC\cong \Delta XYZ[/tex].
[tex]\angle C\cong \angle Z[/tex] (CPCTC)
[tex]m\angle C=m\angle Z[/tex]
[tex]70^\circ=m\angle Z[/tex]
Therefore, the measure of angle Z is 70 degrees.

Step-by-step explanation:
[tex](7a+5b-2c)+(5a+7b)+(2a-7c)+(2a-5b+3c)[/tex]
Distribute:
[tex]=7a+5b-2c+5a+7b+(2a)(2a)+(2a)(-5)+(2a)(3c)+(-7a)(2a)+(-7a)(-5b)+(-7a)(3c)[/tex]
[tex]=7a+5b-2c+5a+7b+4a^2-10ab+6ac-10a^2+35ab-21ac[/tex]
Combine all like terms:
[tex]=(4a^2-14a^2)+(-10ab+35ab)+(6ac-21ac)+(7a+5a)+(5b+7b)+(-2c)[/tex]
[tex]=-10a^2+25ab-15ac+12a+12b-2c[/tex]

In the diagram, the ratios of two pairs of corresponding sides are equal.
Triangles L M N and X Y Z are shown. Side L M is blank, side M N is 3, and side N L is 2. Side X Y is blank, side Y Z is 9, and side Z X is 6.
To prove that △LMN ~ △XYZ by the SAS similarity theorem, it also needs to be shown that
∠N ≅ ∠Z
∠N ≅ ∠X
∠L ≅ ∠Z
∠L ≅ ∠Y
Answer:
∠N ≅ ∠Z
Step-by-step explanation:
In the Side-Angle-Side (SAS) similarity theorem, the included angle of the two given sides of a triangle is also given. This theorem relates two legs of a triangle with the angle formed by the legs.
Comparing the sides of △LMN and △XYZ, it would be observed that the corresponding sides of △XYZ has a scale of 3. So to prove that △LMN ~ △XYZ by the SAS similarity theorem, it would be required to also show that ∠N ≅ ∠Z.
Answer:
A) ∠N ≅ ∠Z

Which statement is true about whether Z and B are independent events?
Z and B are independent events because P(Z∣B) = P(Z).
Z and B are independent events because P(Z∣B) = P(B).
Z and B are not independent events because P(Z∣B) ≠ P(Z).
Z and B are not independent events because P(Z∣B) ≠ P(B).
Answer:
Z and B are independent events because P(Z∣B) = P(Z).
Step-by-step explanation:
After a small online search, I've found a table to complete this problem, that we can see below.
For two events Z and B, we have:
P(Z|B) = probability of Z given that B
such that:
P(Z|B) = P(Z∩B)/P(B)
So, two events are independent if the outcome of one does not affect the outcome of the other.
So, if the probability of Z given B is different than P(Z) (the probability of event Z) means that the events are not independent.
So Z and B are independent if the probability of Z given B is equal to the probability of Z.
P(Z|B) = P(Z)
In the table we can see:
P(Z|B) will be equal to the quotient between all the cases of Z given B (126) and the total cases are given B (280)
P(Z|B) = 126/280 = 0.45
Similarly, we can find P(Z):
And P(Z) = 297/660 = 0.45
So we can see that:
P(Z|B) = P(Z)
Thus, B and Z are independent.
