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.

If f(x) = -x + 5 and g(x) = 3x + 2, Find f(2)*g(2).
Answer:
24
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -x + 5
f(2) = -(2) + 5
Simplify the parentheses by multiplying.
f(2) = -2 + 5
Add.
f(2) = 3
g(x) = 3x + 2
g(2) = 3(2) + 2
Simplify the parentheses by multiplying.
g(2) = 6 + 2
Add.
g(2) = 8
Now they are asking you to multiply
f(2) • g(2)
3 • 8
= 24

Step-by-step explanation:
Trevor is interested in purchasing the local hardware/sporting goods store in the small town of Dove Creek, Montana. After examining accounting records for the past several years, he found that the store has been grossing over $850 per day about 65% of the business days it is open. Estimate the probability that the store will gross over $850 for the following. (Round your answers to three decimal places.)
(a) at least 3 out of 5 business days
(b) at least 6 out of 10 business days
(c) fewer than 5 out of 10 business days
(d) fewer than 6 out of the next 20 business days If the outcome described in part (d) actually occurred, might it shake your confidence in the statement p = 0.65? Might it make you suspect that p is less than 0.65? Explain. Yes. This is unlikely to happen if the true value of p is 0.65. Yes. This is likely to happen if the true value of p is 0.65. No. This is unlikely to happen if the true value of p is 0.65. No. This is likely to happen if the true value of p is 0.65.
(e) more than 17 out of the next 20 business days If the outcome described in part (e) actually occurred, might you suspect that p is greater than 0.65? Explain. Yes. This is unlikely to happen if the true value of p is 0.65. Yes. This is likely to happen if the true value of p is 0.65. No. This is unlikely to happen if the true value of p is 0.65. No. This is likely to happen if the true value of p is 0.65.
Answer:
A) P(X ≥ 3 ) = 0.7648
B) P(X ≥ 6) = 0.7515
C) P(X < 5) = 0.0949
D) P(X < 6) = 0.00031113
Yes. This is likely to happen if the true value of p is 0.65
E) P(X ≥ 17) = 0.012118
No. This is unlikely to happen if the true value of p is 0.65
Step-by-step explanation:
Solving this question means we have to deal with binomial probability distribution which follows a formula;
P(X = x) = C(n, x) * p^(x) * (1 - p)^(n - x)
We are given p = 65% = 0.65
A) probability of getting At least 3 out of the 5 business days, we have;
P(X ≥ 3 ) = P(X = 3) + P(X = 4) + P(X = 5)
And n = 5
Thus;
P(X = 3) = C(5, 3) × 0.65³ × (1 - 0.65)^(5 - 3)
P(X = 3) = 0.3364
P(X = 4) = C(5, 4) × 0.65⁴ × (1 - 0.65)^(5 - 4)
P(X = 4) = 0.3124
P(X = 5) = C(5, 5) × 0.65^(5) × (1 - 0.65)^(5 - 5)
P(X = 5) = 0.116
Thus;
P(X ≥ 3 ) = 0.3364 + 0.3124 + 0.116
P(X ≥ 3 ) = 0.7648
B) Probability of getting at least 6 out of the 10 business days.
P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)
From online binomial calculator, we have;
P(X = 6) = 0.2377
P(X = 7) = 0.2522
P(X = 8) = 0.1757
P(X = 9) = 0.0725
P(X = 10) = 0.0134
P(X ≥ 6) = 0.2377 + 0.2522 + 0.1757 + 0.0725 + 0.0134
P(X ≥ 6) = 0.7515
C) probability of getting fewer than 5 out of the 10 business days.
P(X < 5) = P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1)
From online binomial calculator, we have;
P(X = 4) = 0.0689
P(X = 3) = 0.0212
P(X = 2) = 0.0043
P(X = 1) = 0.0005
P(X < 5) = 0.0689 + 0.0212 + 0.0043 + 0.0005
P(X < 5) = 0.0949
D)probability of getting fewer than 6 out of the next 20 business days;
P(X < 6) = P(X = 5) + P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1)
From online binomial calculator, we have;
P(X = 5) = 0.000261
P(X = 4) = 0.000044
P(X = 3) = 0.0000056
P(X = 2) = 0.0000005
P(X = 1) = 0.00000003
P(X < 6) = 0.000261 + 0.000044 + 0.0000056 + 0.0000005 + 0.00000003
P(X < 6) = 0.00031113
Yes, in this scenario, It is likely to happen and I would think p is less than 0.65 because probability is less than 1 out of 1000.
E) probability of getting more than 17 out of the next 20 business days.
P(X ≥ 17) = P(X = 18) + P(X = 19) + P(X = 20)
From online binomial calculator, we have;
P(X = 18) = 0.0099846
P(X = 19) = 0.00195187
P(X = 20) = 0.00018125
P(X ≥ 17) = 0.0099846 + 0.00195187 + 0.00018125
P(X ≥ 17) = 0.012118
Probability is around 12 in 100 and not up to 50%. Thus, This is unlikely to happen if the true value of p is 0.65

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))
