Answer:
This is a right angle triangle so
[tex] {hyp}^{2} = {opp}^{2} + {adj}^{2} [/tex]
[tex] {42}^{2} = a {}^{2} + 30 {}^{2} \\ 1764 = a {}^{2} + 900 \\ {a }^{2} = 1764 - 900 \\ a { }^{2} = 864 \\ a = \sqrt{864 } \\ a = 29.39[/tex]

Probability helps us to know the chances of an event occurring. Sam should use the second spinner.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that Sam plans to use a spinner to choose which friend to invite to the movies, he wants each friend to have a fair chance of being selected.
The term fair means that everyone or everything that is in the list should have equal opportunity.
Now, since Sam wants each friend to have a fair chance of being selected, therefore, the area on the spinner for each friend should be equal.
Hence, Sam should use the second spinner.

Solve the equation x2 - 6x – 41 = 0 to the nearest tenth.
sin3(2x) = 1/2sin(2x) [1 − cos(4x)]
Answer:
I suppose we start with sin³(2*x) and we want to get:
(1/2)*sin(2*x)*(1 - cos(4*x))
Here we will use the relationships:
cos²(x) + sin²(x) = 1
and
cos²(x) = (1 + cos(2x))/2
Now let's start:
sin³(2*x) = sin(2*x)*sin²(2*x)
and we can write:
sin²(2*x) = 1 - cos²(2*x)
replacing that in the above equation we get:
sin³(2*x) = sin(2*x)*sin²(2*x) = sin(2*x)*(1 - cos²(2*x))
now we can use: cos²(2*x) = (1 + cos(2*2*x))/2
cos²(2*x) = (1 + cos(4*x))/2
if we replace that in the equation above we get:
sin³(2*x) = sin(2*x)*(1 - cos²(2*x)) = sin(2*x)*( 1 - (1 + cos(4*x))/2)
sin³(2*x) = sin(2*x)*( 1 - 1/2 - cos(4*x)/2)
sin³(2*x) = sin(2*x)*( 1/2 - cos(4*x)/2)
sin³(2*x) = sin(2*x)*( 1 - cos(4*x))/2
sin³(2*x) = (1/2)*sin(2*x)*( 1 - cos(4*x))
In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. Find the length of r, to the nearest 10th of an inch.
In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. the length of r, to the nearest 10th of an inch, is 365.9 Inches
What is a law of sine?Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.
a/Sin A = b/Sin B = c/Sin C
Where a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.
Hence,
58/Sin 19 = r/Sin 115
r = 58 Sin 115/ Sin 19
= 365.9 Inches
Therefore, In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. the length of r, to the nearest 10th of an inch, is 365.9 Inches.

Determine the term containing y^5 in the expansion of (x-3y)^8
Answer:
-13608x³y⁵Step-by-step explanation:
Since y has degree of 5, x has degree of:
8 - 3 = 5The required term of the given binomial expansion (x - 3y)⁸ is:
8C₅(x³)(-3y)⁵,The value of the constant:
8C₅ = 8!/5!(8-5)! = 7*8 = 56 * (-3)⁵= -13608So the full term is:
336x³(-3)⁵y⁵ = -13608x³y⁵answer this correctly.
