If 7π/12= 9π/ 12 - 2π/12, evaluate sin 7π/12
The requried solution of the given trigonometric function is sin7π/12 is (√3 + 1)/(2√2).
We know that 7π/12 = 9π/12 - 2π/12.
So, we can rewrite sin(7π/12) as sin(9π/12 - 2π/12).
Using the trigonmetric identity,
sin(A - B) = sinAcosB - cosAsinB, we can rewrite sin(9π/12 - 2π/12) as sin(9π/12)*cos(2π/12) - cos(9π/12)*sin(2π/12).
We know that,
sin(2π/12) = sin(π/6) = 1/2 and cos(2π/12) = cos(π/6) = √3/2.
Also, sin(9π/12) = sin(3π/4) = 1/√2 and cos(9π/12) = cos(3π/4) = -1/√2.
Substituting these values, we get:
= sin(7π/12) = sin(9π/12 - 2π/12)
= sin(9π/12)cos(2π/12) - cos(9π/12)sin(2π/12)
= (1/√2)(√3/2) - (-1/√2)(1/2)
= (√3/2√2) + (1/2√2)
= (√3 + 1)/(2√2)

Two side and an angle (SSA) trigonometry
The measurements only result in one triangle.
How to explain the triangleWhen we apply the Law of Sines, we get:

sin(B) = (16.7/14) sin(B) = 0.580sin(35)
sin(B) ≈ 0.580
We obtain either B = 35.8 degrees or B = 144.2 degrees when we take the inverse sine of both sides.
We know that C = 180 - 35 - 35.8 109.2 degrees since the total of the angles in a triangle is 180 degrees.
The length of the third side, c, can be determined using the Law of Cosines as follows: c 10.8
We have c 31.2 for B 144.2 degrees.
A legal triangle with side lengths of 14, 16, and 10 with angles of 35, 35.8, and 109.2 degrees is one where B 35.8 degrees.

what is the solution to x=sqrt-x+6
Answer:
x = √(-x) + 6 are x = 9 and x = -12
Step-by-step explanation:
To find the solution for "x" in the equation x = √(-x) + 6, we can follow these steps:
Start with the original equation: x = √(-x) + 6.
Square both sides of the equation to eliminate the square root on the right-hand side: (x)^2 = (√(-x) + 6)^2.
Simplify the right-hand side by applying the distributive property: (x)^2 = (√(-x))^2 + 2(√(-x))(6) + (6)^2.
Simplify further by noting that (√(-x))^2 = -x: (x)^2 = -x + 72 + 36.
Combine like terms: (x)^2 = -x + 108.
Move all terms to one side of the equation: (x)^2 + x - 108 = 0.
This is now a quadratic equation. We can solve for "x" by factoring, using the quadratic formula, or by graphing. Factoring or using the quadratic formula would be appropriate methods in this case.
Factoring the quadratic equation, we get: (x - 9)(x + 12) = 0.
Setting each factor equal to zero and solving for "x", we get two possible solutions: x - 9 = 0 or x + 12 = 0.
Solving for "x" in each case, we get: x = 9 or x = -12.
So, the solutions to the equation x = √(-x) + 6 are x = 9 and x = -12.

Mark bought a CD for $500 that earns 3% APR and is compounded annually. The
CD matures in 3 years. How much will this CD be worth at maturity?
O$503.03
O$509.09
O $546.36
O$545.45
Answer:
Answer: (C) $546.36.
Step-by-step explanation:
To find the future value of the CD at maturity, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the future value of the CD
P = the principal amount (the initial amount invested), which is $500
r = the annual interest rate, which is 3% expressed as a decimal (0.03)
n = the number of times the interest is compounded in a year, which is once annually
t = the time the money is invested for, which is 3 years
Substituting the given values into the formula, we get:
A = 500(1 + 0.03/1)^(1*3)
A = 500(1.03)^3
A = 546.36
Therefore, the CD will be worth $546.36 at maturity. Answer: (C) $546.36.
Max and Pam deposit $600.00 into a savings account which earns 4% interest compounded quarterly. They want to use the money in the account to go on a trip in 3 years. How much will they be able to spend?
Max and Pam will be able to spend $676.1 on their trip.
What is the balance after 3 years?The formula accrued amount in a compounded interest is expressed as;
A = P( 1 + r/n )^( n × t )
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given the data in the question;
Principal P = $600.00
Compounded quarterly n = 4
Time t = 3 years
Interest rate r = 4%
Accrued amount A = ?
First, convert R as a percent to r as a decimal
r = R/100
r = 4/100
r = 0.04 rate per year.
Plug the given values into the above formula and solve for A.
A = P( 1 + r/n )^( n × t )
A = $600( 1 + 0.04/4 )^( 4 × 3 )
A = $600( 1 + 0.01 )^( 12 )
A = $600( 1.01 )^( 12 )
A = $676.1
Therefore, the accrued amount after 3 years is $676.1.

Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.)
Tangent to both axes, center in the second quadrant, radius 4
Answer:
[tex](x+4)^2+(y-4)^2=16[/tex]
Step-by-step explanation:
A tangent is a straight line that touches a circle at only one point.
Since the circle is tangent to both axes, and the center of the circle is in the second quadrant, the center of the circle lies on the line y = -x.
As the circle is tangent to the x-axis, the distance between the center of the circle and the x-axis is equal to the radius of the circle.
Similarly, as the circle is tangent to the y-axis, the distance between the center of the circle and the y-axis is also equal to the radius of the circle.
Therefore, the center of the circle will be 4 units to the left of the y-axis and 4 units up from the x-axis. Therefore, the coordinates of the center are (-4, 4).
[tex]\boxed{\begin{minipage}{5 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
Substitute the center (-4, 4) and the radius, r = 4, into the standard equation of a circle:
[tex]\implies (x - (-4))^2+(y-4)^2=4^2[/tex]
[tex]\implies (x+4)^2+(y-4)^2=16[/tex]
Therefore, the equation of the circle that satisfies the given conditions is:

De un paralelogramo ABCD conocemos A(1,3), B(5,1), C(-2,0). Halla las coordenadas del vértice D.
The coordinates of vertex D are (2, -2).
Given that ABCD is a parallelogram.
Coordinates of A = (1, 3) and B = (5, 1) and C = (-2, 0).
Let the fourth coordinates of the point D be (x, y).
So, the slope of AB and CD will be equal since ABCD is parallelogram and opposite sides of parallelogram are parallel and slopes of parallel are equal.
Slope of CD = (y - 0)/(x - (-2)) = y/(x + 2)
Slope of AB = (1 -3)/(5 - 1) = -2/4 = -1/2
So, y/(x + 2) = -1/2
2y = -x - 2
x + 2y = -2 ........... (i)
again slopes of AC and BD are equal for the same reason.
Slope of AC = (3 - 0)/(1 - (-2)) = 3/3 = 1
Slope of BD = (y - 1)/(x - 5)
So, (y - 1)/(x - 5) = 1
y - 1 = x - 5
x - y = 4 ...........(ii)
equation (i) - equation (ii) we get,
(x + 2y) - (x - y) = -2 -4
3y = -6
y = -2
Putting y = -2 in equation (ii) we get,
x - (-2) = 4
x = 4 - 2 = 2
So the coordinates of fourth point are (2, -2).

For what value of c is the number "a" a solution of the equation?
4x + 1 + 7c = 6c - 3x + 6; a = -6
c =
Answer:
c = 47
Step-by-step explanation:
The solution of the equation is the value of x.
Given "a" is a solution of the equation, and a = -6, to find the value of c, substitute x = -6 into the given equation and solve for c.
⇒ 4x + 1 + 7c = 6c - 3x + 6
⇒ 4(-6) + 1 + 7c = 6c - 3(-6) + 6
⇒ -24 + 1 + 7c = 6c + 18 + 6
⇒ -23 + 7c = 6c + 24
⇒ -23 + 7c - 6c = 6c + 24 - 6c
⇒ -23 + c = 24
⇒ -23 + c + 23 = 24 + 23
⇒ c = 47
Therefore, the value of c that makes a = -6 a solution of the equation is 47.
The value of 'c' for which 'a' is a solution of the given equation can be found by substituting 'a' into the equation and simplifying. In this case, 'a' is -6, and by substituting this value into the equation and simplifying, we find that when 'c' is 47, 'a' becomes a solution.
Explanation:To find the value of c for which a is a solution of the equation, we have to substitute the value of a into the equation and solve for c. Here, a = -6, which means x can be considered as -6 in the equation.
Step 1: Substitute the value of a (x) into the equation. So the equation 4x + 1 + 7c = 6c - 3x + 6 becomes 4(-6) + 1 + 7c = 6c - 3(-6) + 6.
Step 2: Simplify both sides of the equation. We get -24 + 1 + 7c = 6c + 18 + 6.
Step 3: Continue simplifying to -23 + 7c = 6c + 24.
Step 4: By rearranging terms, we find c = 47.

A window in Lynn and Jorge's house needs to be
replaced. The rectangular window is 3 feet 5 inches
tall and 2 feet 4 inches wide. Change each of the
measurements to inches
(a) Find the perimeter of the window in inches.
(b) If the perimeter needs to be sealed with insulation
that is $0.80 per inch, how much will it cost to insulate
the perimeter?
The perimeter of the window in inches is 138 inches.
It will cost $110.40 to insulate the perimeter of the window.
How to change the measurements to inches?To change the measurements to inches, we can use the fact that 1 foot is equal to 12 inches. So:
The height of the window in inches is (3 feet x 12 inches/foot) + 5 inches = 36 inches + 5 inches = 41 inches.
The width of the window in inches is (2 feet x 12 inches/foot) + 4 inches = 24 inches + 4 inches = 28 inches.
(a) The perimeter of the window in inches is the sum of the lengths of all four sides. We can use the formula for the perimeter of a rectangle to find it:
Perimeter = 2(length + width)
Plugging in the values we found:
Perimeter = 2(41 inches + 28 inches) = 138 inches
So the perimeter of the window in inches is 138 inches.
(b) We must divide the cost per inch by the perimeter in order to determine the cost of insulating the perimeter:
The following equation can be used to calculate the cost:
Cost = Perimeter x Cost per Inch
Cost = 138 inches x $0.80/inch = $110.40
So it will cost $110.40 to insulate the perimeter of the window.

The given equation for the debt of Country G is A = 18.5(0.995), where A represents the debt after one year, and the factor of 0.995 represents the decay factor. To estimate the debt after 15 years, we can use this equation iteratively.
After the first year, the debt would be A = 18.5(0.995) = 18.4 billion dollars. To find the debt after the second year, we can use the same equation, but replace the initial debt of 18.5 billion dollars with the debt after one year, which is 18.4 billion dollars. Therefore, the debt after two years would be A = 18.4(0.995) = 18.3 billion dollars.
We can repeat this process for each subsequent year, using the previous year's debt to calculate the next year's debt. After 15 years, the debt would be:
A = 18.5(0.995)¹⁵
A = 18.5(0.80424)
A = 14.8866 billion dollars
Rounding to the nearest hundredth, the debt of Country G after 15 years would be approximately $14.89 billion dollars.
It's important to note that this estimate assumes that the decay factor remains constant over the 15-year period. In reality, economic and political factors could impact the decay rate and the actual debt of Country G.

A wheel has a radius of 40cm and is turning 112rpm. What is the angular velocity of the wheel? What distance does a point on the wheel travel in 1 minute
The angular velocity of the wheel is 11.74 radians per second and the distance travelled is 2.81 km/min.
The angular velocity is given by the formula rpm×2π/60
Angular velocity = 2 × 3.14 × 112/60
Multiply the numerator followed by division by denominator
Angular velocity = 703.36/60
Angular velocity = 11.72 radians per second
The distance travelled will be given by the formula -
Distance = circumference × revolutions per minute
Distance = 2 × 40 × 3.14 × 112
Multiply the values on Right Hand Side
Distance = 281,227 cm/min
As, 100 cm is 1 m and 1000 m is 1 km, the distance will be 2.81 km/min.
Thus, the angular velocity is 11.72 radians per second and distance is 2.81 km/min.

can someone help me on number 3
Answer:
[tex]P= 49.2m[/tex], [tex]A=140.4m^2[/tex]
Step-by-step explanation:
The diagonal splits the rectangle into two right triangles so we can use Pythagorean theorem to find the length of the missing side.
Pythagorean theorem states that a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides
So we can label our unknown side as x
x^2 + 9^2 = 18^2
x^2 + 81 = 324
Subtract 81 from both sides to isolate the x
x^2 = 243
Find the square root of both sides
√x^2 = √243
x ≈ 15.6
(The instruction said round to the nearest 10th).
So now we know
l = 15.6m and w = 9m
P= 2l + 2w
A= lw
P= 2(15.6) + 2(9)
P= 31.2 + 18
P= 49.2m
A=15.6(9)
A=140.4m^2
