The solution to the system of equations is (0,1).
To solve the system of equations using elimination, we need to eliminate one of the variables. In this case, we will eliminate x by multiplying the first equation by -2 and the second equation by 6.
First equation: 6x+3y=3
Second equation: 2x+7y=7
Multiply the first equation by -2: -12x-6y=-6
Multiply the second equation by 6: 12x+42y=42
Now we can add the two equations together to eliminate x:
-12x-6y=-6
+12x+42y=42
_______________
0x+36y=36
Now we can solve for y:
36y=36
y=1
Now we can plug y back into one of the original equations to solve for x:
6x+3(1)=3
6x+3=3
6x=0
x=0
So the solution to the system of equations is (0,1).

Solve for the exact solutions in the interval (0,2π). If the equation has no solutions, respond with DNE Cos (2x) cos(x) - sin(2x)sin(x) = - ✓3 / 2
____________
The exact solutions are x ≈ 0.590, x ≈ 2.552, and x ≈ 5.103.
The equation we are solving for exact solutions in the interval (0,2π) is Cos (2x) cos(x) - sin(2x)sin(x) = - √3 / 2.
First, let's use the double angle formula for cosine to simplify the equation:
cos(2x) = 1 - 2sin^2(x)
Substituting this into the equation, we get:
(1 - 2sin^2(x))cos(x) - sin(2x)sin(x) = - √3 / 2
Next, let's use the double angle formula for sine to simplify the equation further:
sin(2x) = 2sin(x)cos(x)
Substituting this into the equation, we get:
(1 - 2sin^2(x))cos(x) - 2sin^2(x)cos(x) = - √3 / 2
Combining like terms and rearranging, we get:
4sin^2(x)cos(x) - cos(x) = √3 / 2
Factoring out cos(x), we get:
cos(x)(4sin^2(x) - 1) = √3 / 2
Dividing both sides by (4sin^2(x) - 1), we get:
cos(x) = (√3 / 2) / (4sin^2(x) - 1)
Using the Pythagorean identity, sin^2(x) + cos^2(x) = 1, we can substitute for sin^2(x):
cos(x) = (√3 / 2) / (4(1 - cos^2(x)) - 1)
Multiplying both sides by (4(1 - cos^2(x)) - 1), we get:
cos(x)(4(1 - cos^2(x)) - 1) = √3 / 2
Expanding and rearranging, we get:
4cos^3(x) - 5cos(x) + √3 / 2 = 0
This is a cubic equation, which is difficult to solve algebraically. However, we can use a graphing calculator to find the approximate solutions. The solutions are x ≈ 0.590, x ≈ 2.552, and x ≈ 5.103.
Since all of these solutions are in the interval (0,2π), the exact solutions are x ≈ 0.590, x ≈ 2.552, and x ≈ 5.103.

Every day Ms.Twinkle walks around a park near her house. The park is the shape of a rectangle 2 mi long and 1 3/10 mi wide. How far does she walk.
Ms. Twinkle walks a total of 6.6 miles around the park.
What is perimeter ?
Perimeter is the total distance around the outside of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.
To find how far Ms. Twinkle walks, we need to find the perimeter of the rectangle-shaped park, which is the sum of the lengths of all its sides.
The length of the park is 2 miles and the width is 1 3/10 miles. We can write the width as a mixed number of 1 + 3/10 = 13/10 miles.
Therefore, the perimeter of the park is:
Perimeter = 2(length + width)
Perimeter = 2(2 + 13/10)
Perimeter = 2(20/10 + 13/10)
Perimeter = 2(33/10)
Perimeter = 66/10
Perimeter = 6.6 miles

A quadrilateral is on a coordinate plane at points A(-3, 1) B(1, 4) C(5, 1) D(1, -2).
Which sides are congruent? (Select all that apply)
AB
BC
CD
AD
Answer:
AB and CD.
Step-by-step explanation:
To check if two sides of a quadrilateral are congruent, we need to find the length of each side. We can use the distance formula to calculate the length of each side:
AB = √[(1 - 4)^2 + (4 - 1)^2] = √(9 + 9) = 3√2
BC = √[(5 - 1)^2 + (1 - 4)^2] = √(16 + 9) = √25 = 5
CD = √[(1 - 1)^2 + (-2 - 1)^2] = √9 = 3
AD = √[(-3 - 1)^2 + (1 - (-2))^2] = √(16 + 9) = √25 = 5
Therefore, AB and CD have the same length and are congruent, while BC and AD have the same length and are congruent.
So the correct answer is AB and CD.
Suppose an investment compounds with an annual interest rate of
11.1%. The equation below models a final balance A given principal
P and time t. Use properties of exponents to approximate the
equivalent monthly interest rate. Enter the approximate monthly
rate as a percentage rounded to two decimal places.
A = P (1.111)ª
Answer:
To approximate the monthly interest rate, we need to use the formula for the annual percentage rate (APR) that takes into account the effect of compounding:
APR = (1 + r/m)^m - 1
where r is the annual interest rate, m is the number of compounding periods per year, and APR is the annual percentage rate.
In this case, r = 11.1% and m = 12 (since there are 12 months in a year). We want to solve for the monthly interest rate, which we can call r_m:
r_m = (1 + r/12)^12 - 1
r_m = (1 + 0.111/12)^12 - 1
r_m = 0.009141
To convert this to a percentage, we multiply by 100:
r_m = 0.9141%
Therefore, the approximate monthly interest rate is 0.9141%, rounded to two decimal places.

Suppose that y varies directly as the cube root of x, and that y=100 when x=6859. What is y when x=1331? Round your answer to two decimal places if necessary.
The value of y = 57.86 when x = 1331.
We are given that y varies directly as the cube root of x. This means that the equation relating y and x is of the form:
y = k * cube_root(x)
Where k is the constant of proportionality. We are also given that y = 100 when x = 6859. We can use this information to find the value of k:
100 = k * cube_root(6859)
k = 100 / cube_root(6859)
k = 100 / 19
k = 5.26
Now we can use the value of k to find y when x = 1331:
y = 5.26 * cube_root(1331)
y = 5.26 * 11
y = 57.86
Therefore, y is approximately 57.86 when x is 1331. We can round this answer to two decimal places to get:
y = 57.86

To solve this equation, we need to get rid of the fractions by multiplying each term by the least common multiple (LCM) of the denominators. The LCM of x+6 and 5x+30 is (x+6)(5x+30).
Multiplying each term by the LCM gives us:
(5)(x+6)(5x+30)/(x+6) = (7)(x+6)(5x+30)/(5x+30) - 2(x+6)(5x+30)
Simplifying the fractions and distributing the terms gives us:
5(5x+30) = 7(x+6) - 2(x+6)(5x+30)
Expanding and simplifying the terms gives us:
25x + 150 = 7x + 42 - 10x^2 - 180x - 360
Combining like terms and rearranging gives us:
10x^2 + 198x + 468 = 0
Using the quadratic formula, we can find the values of x:
x = (-198 ± √(198^2 - 4(10)(468)))/(2(10))

A metal plate is supposed to be 15. 75cm long but after it was cut, it measured 15. 71 determine relative error
The relative error of the metal plate is -0.0025
The relative error compares the difference between the measured value and the actual value to the actual value itself. Mathematically, it's calculated as:
Relative Error = (Measured Value - Actual Value) / Actual Value
In this case, the metal plate was supposed to be 15.75 cm long, but it measured 15.71 cm after it was cut. Therefore, the measured value is 15.71 cm, and the actual value is 15.75 cm. Plugging these values into the formula for relative error, we get:
Relative Error = (15.71 - 15.75) / 15.75 = -0.0025
The relative error is negative because the measured value is less than the actual value. In other words, the measured value has an error of -0.25% relative to the actual value. This means that the measured value is 0.25% less than the actual value.

The given equation is x2−9/18−x−3/12=x+3/x
(a) The restrictions on x are that x cannot equal 0, 6, or -4. This is because if x were to equal any of these values, the denominator of one of the fractions in the equation would equal 0, which is undefined.
(b) The least common denominator of the fractions in the equation is 36. This is because 36 is the smallest number that is divisible by 18, 12, and x.
(c) To solve the equation, we can multiply each term by the least common denominator to eliminate the fractions:
36x2 - 18(9) - 36x - 3(3) = 36x + 3(36)
Simplifying and rearranging the terms gives us:
36x2 - 72x - 207 = 0
Using the quadratic formula, we can find the values of x:
x = (-(-72) ± √((-72)2 - 4(36)(-207)))/(2(36))
Simplifying gives us:
x = (72 ± √12960)/72
So the solutions are x = (72 + √12960)/72 and x = (72 - √12960)/72.
However, we must check these solutions against the restrictions on x. The first solution, (72 + √12960)/72, is approximately 6.8, which does not violate any of the restrictions. The second solution, (72 - √12960)/72, is approximately -0.8, which also does not violate any of the restrictions. Therefore, the solutions to the equation are x = (72 + √12960)/72 and x = (72 - √12960)/72.

Find the final amount for an investment of $5,000 over 5 years at an annual interest rate of 6% if the interest is compounded quarterly.
The final amount for the investment of $5,000 is $ 6,749.29.
Compound interest:Compound interest is a type of interest calculation in which the interest earned on an initial principal amount is added to the principal, and the new total amount earns interest in subsequent periods.
This means that the interest earned in each period is based on the total amount, which includes both the principal and the accumulated interest from previous periods.
The formula used for compound interest:
[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]Where:
P = Initial investment
r = Rate of interest (as a decimal)
n = Number of compounds
t = Time period in years
Here we have
P = $5,000,
r = 6% = 0.06,
n = 4 (since the interest is compounded quarterly), and
t = 5 years.
Using the above formula
[tex]A = 5000(1 + 0.06/4)^{(4*5)[/tex]
[tex]A = 5000(1.015)^{20[/tex]
[tex]A = 5000(1.34985711)[/tex]
[tex]A =\$6,749.29[/tex]
Therefore,
The final amount for the investment of $5,000 is $ 6,749.29.

Gail has $5,500 that she wants to put in a new savings account. She is considering two banks that are very similar. One difference she notices are the interest rates: • Neighborhood Bank - 1.2% interest, compounded annually • Beautiful Day Bank - 1.2% interest, compounded daily Based on interest, which bank would you suggest Gail pick if she plans to have her money in the account for 15 years?
Gail should pick a Beautiful bank if she plans to have her money in the account for 15 years.
How to determine which will be best bank?To determine which bank would be better for Gail, we need to calculate the future value of her investment after 15 years for each bank and compare the results.
For Neighborhood Bank, we can use the formula:
FV = P(1 + r/n)^(n*t)
where FV is the future value,
P is the principal (the initial amount invested),
r is the annual interest rate (as a decimal),
n is the number of times the interest is compounded per year,
and t is the number of years.
Plugging in the values, we get:
FV = 5,500(1 + 0.012/1)^(1*15)
FV = 5,500(1.012)^15
FV = 7,130.34
For Beautiful Day Bank, we can use the formula:
FV = P(1 + r/n)^(n*t)
Plugging in the values, we get:
FV = 5,500(1 + 0.012/365)^(365*15)
FV = 5,500(1.000032876)^5475
FV = 7,145.25
Therefore, Beautiful Day Bank would be the better choice for Gail, as she would earn a higher amount of interest and end up with a higher future value for her investment after 15 years.

Rotate point A 180 counterclockwise about the origin to get point A'. Which of the following coordinate is A'?
Rotate point A 180 counterclockwise about the origin to get point A'. -2,-3 coordinate is A'
What is counterclockwise rotation?
Rotations that are counterclockwise (CCW) travel in the opposite direction from how a clock's hands move. Positive numerals are used to indicate these rotations.
Rotation in either a clockwise or anticlockwise direction refers to a change in the electrical activity flowing through the heart in a horizontal plane. Consider the observer as being at the bedside of the sufferer. It is known as anticlockwise rotation if the patient's heart's electrical activity has shifted more to their right side. It is known as clockwise rotation if the patient's heart's electrical activity has shifted more to the left.
Our point A(x,y) rotates 180 degrees anticlockwise around the origin to become A' (-x,-y). Making both x and y negative is all we do as a result.
Here we can see in the graph ‘A’ is present on (2,3)
So the -2,-3 coordinate is A’.
Hence the correct answer is c, -2,-3

Sketch the least positive angle and find the values of the six trigonometric functions
3x+5y=0 , x≥0
The least positive angle is 180 - θ.
To sketch the least positive angle and find the values of the six trigonometric functions for the given equation 3x + 5y = 0, x ≥ 0, we need to first find the slope and y-intercept of the equation.
The slope of the equation is -3/5 and the y-intercept is 0. This means that the line passes through the origin and has a negative slope.
To sketch the least positive angle, we need to find the angle between the x-axis and the line. Since the slope is negative, the angle will be in the second quadrant. The least positive angle is the reference angle in the second quadrant, which is 180 - θ.
To find the values of the six trigonometric functions, we can use the slope and y-intercept to find the coordinates of a point on the line. One such point is (5, -3).
Using these coordinates, we can find the values of the trigonometric functions:
sin θ = -3/√(5^2 + (-3)^2) = -3/√34
cos θ = 5/√(5^2 + (-3)^2) = 5/√34
tan θ = -3/5
csc θ = √34/-3
sec θ = √34/5
cot θ = -5/3
Therefore, the least positive angle is 180 - θ and the values of the six trigonometric functions are as follows:
sin θ = -3/√34
cos θ = 5/√34
tan θ = -3/5
csc θ = √34/-3
sec θ = √34/5
cot θ = -5/3

A triangle has angle measurements of 3°, 35°, and 142°. What kind of triangle is it?
The triangle is an obtuse triangle.
What is a valid triangle?
A valid triangle is a geometric figure with three sides and three angles. To be considered a valid triangle, it must satisfy the following conditions:
1. The sum of the lengths of any two sides must be greater than the length of the third side. This is known as the Triangle Inequality Theorem, and it ensures that the three sides can form a closed figure.
2. The measure of each angle must be less than 180 degrees. This is known as the Angle Sum Theorem, and it ensures that the three angles can fit inside a two-dimensional plane.
The sum of the angles of any triangle is always 180 degrees.
So, if a triangle has angle measurements of 3°, 35°, and 142°, we can add them up to check whether they add up to 180 degrees:
3° + 35° + 142° = 180°
Since the sum of the angles is 180 degrees, the triangle is a valid triangle.
Now, we can classify the triangle based on the measure of its angles. Since the measure of one angle (142°) is greater than 90 degrees, the triangle is an obtuse triangle.
We cannot determine the length of the sides of the triangle based on the angle measures provided. So, we cannot classify the triangle based on the length of its sides.
Therefore, the triangle is an obtuse triangle.
