Answer:

The sine function for the given parameters is y = 4 sin ( pi/2 * x ) + 1. The period is 12, the amplitude is 4, the midline is y = 1 and the y-intercept is (0, 1). The function is not a reflection of its parent function over the x-axis.

Step-by-step explanation:

To solve a sine function with the given features, one must first identify the midline, amplitude, period, and phase shift of the function. The midline is the average of the maximum and minimum values of the graph, while the amplitude is half of the difference between these two values. The period is the length of one cycle in radians, and the phase shift is how much it has been shifted from its parent function over the x-axis.

The equation is satisfied for the gcd(30, 21) and it is: -30 + 21 = 3.

For the gcd(a, b) values in exercise 1.9, the extended Euclidean algorithm (Theorem 1.11) can be used to find integers u and v such that au + bv = gcd(a, b).

We start by using the Euclidean algorithm to calculate the gcd(a, b). We then iteratively calculate the remainder, quotient, and coefficients for each step. We use the equation a = qb + r, where q is the quotient and r is the remainder. We then use the equation r = a - qb to find the value of u and v.

For example, consider gcd(30, 21). We use the Euclidean algorithm to calculate the gcd. We get that gcd(30, 21) = 3. We then use the equation a = qb + r to calculate the remainder, quotient, and coefficients. We get that 30 = 1(21) + 9. We then use the equation r = a - qb to find the values of u and v. So, 9 = 30 - 1(21), which gives us that u = -1 and v = 1. This means that the equation is satisfied for the gcd(30, 21) and it is: -30 + 21 = 3.

So, adjusted to three decimal places, the lacking angles in the triangle are B = 80°24', a = 1.042 cm, and c = 5.852 cm.

The number of important digits is the total number of digits, excluding the decimal point, all leading zeros, and some following zeroes. The number of decimal points is the number to the left of the decimals.

We are given that triangle ABC is a right triangle with C = 90°, A = 9° 36', and b = 5.812 cm.

To find B, we can use the fact that the sum of the angles in a triangle is 180°. Therefore, we have:

B + A + C = 180°

B + 9°36' + 90° = 180°

B = 80°24'

To find a, we can use the trigonometric function tangent.

We have:

tan A = opposite/adjacent

tan 9°36' = a/b

Solving for a, we get:

a = b tan A = 5.812 cm tan 9°36' ≈ 1.042 cm

The Pythagorean theorem, which says that in a right triangle, the square of the hypotenuse equals the total of the squares of the two sides (a and b), can be used to determine c.

We have:

c² = a² + b²

c² = (1.042 cm)² + (5.812 cm)²

c² ≈ 34.235 cm²

c ≈ √34.235 cm²

c ≈ 5.852 cm

Therefore, the missing parts of the triangle are B ≈ 80°24', a ≈ 1.042 cm, and c ≈ 5.852 cm, rounded to three decimal places.

Answer:

3 miles

Step-by-step explanation:

The distance between Arati and Ava can be calculated using the Law of Cosines. Let's call the distance between Arati and Ava as "d". We know that:

a = 2 (distance skied by Arati)

b = 3 (distance skied by Ava ) c = d (distance between Arati and Ava) A = 45 (angle between a and b)

Plugging these values into the Law of Cosines formula:

d^2 = 2^2 + 3^2 - 2 * 2 * 3 * cos(45)

d^2 = 4 + 9 - 12 * (√2 / 2)

d^2 = 13 - 12 * √2

d = √(13 - 12 * √2)

To the nearest mile, the distance between Arati and Ava is approximately 3 miles.

Answer:

Step-by-step explanation:

Absolute Change:

The absolute change in the politician's support is calculated as the difference between the final support percentage (53%) and the initial support percentage (32%):

53% - 32% = 21 percentage points

So, the absolute change in the politician's support is 21 percentage points.

Relative Change:

The relative change in the politician's support is calculated as the absolute change divided by the initial support percentage, multiplied by 100 to express it as a percentage:

(21 / 32) * 100 = 65.625%

Rounding to the nearest tenth of a percent, the relative change in the politician's support is 65.6%.

So, the absolute change in the politician's support is 21 percentage points, and the relative change is 65.6%.

In this case, the absolute change in the politician's support is an increase of 21 percentage points, and the relative change is an increase of 65.6%.

In this situation, the absolute change in the politician's support can be calculated by subtracting the original value from the new value. So, 53% (new value) - 32% (original value) = 21%. Thus, the absolute change in support is 21 percentage points.

The relative change is the absolute change divided by the original value. So, 21% (absolute change) ÷ 32% (original value) = 0.65625. To get the relative change as a percentage, we need to multiply this decimal by 100, and round to the nearest tenth of a percent, which gives us 65.6%.

Therefore, the politician's support has increased by an absolute change of 21 percentage points, and a relative change of 65.6%.

Answer: the right option is (A) II only

Step-by-step explanation:

The two lines have same slope with opposite signs thus, the linear routes are perpendicular, and Ty and Leo will pass through a common coordinate.

A perpendicular is a straight line in mathematics that forms a right angle (90 degrees) with another line. In other words, two lines are perpendicular to one another if they connect at a right angle. If two segments PQ and RS connect at right angles, we may say that they are perpendicular to one another.

For the given coordinates of Ty and Leo let us calculate the slope of the line.

The slope of the line is given as:

m = (y2 - y1) / (x2 - x1)

For Ty:

m = (1 - 3) / (0 + 1) = -2

For Leo:

m = (2 - 4) / (0 - 1) = 2

Answer:

m∠Y = 60

WY = 7 in

Step-by-step explanation:

It's an isosceles triangle (2 sides are equal), therefore m∠W = m∠Y because the base angles of an isosceles triangle are equal.

Sum of interior angles of a triangle is 180.

let x = m∠W = m∠Y

2x + 60 = 180

2x = 180 - 60 = 120

x = 120/2 = 60

m∠Y = 60

Since all 3 angles = 60, now we know it's an equilateral triangle, therefore WY = 7 in

Answer:

Stefan borrowed $8000 on his car loan and $4000 on his student loan.

Step-by-step explanation:

a. Let x be the amount of money Stefan borrowed on his car loan and y be the amount he borrowed on his student loan. According to the problem, Stefan borrowed twice as much on his car loan as on his student loan, so x = 2y.

b. The annual interest on the car loan is $360 more than the interest on the student loan. We can set up an equation as follows:

0.08x - 0.07y = 360

c. Substituting x = 2y from equation (a) into equation (b), we get:

0.08(2y) - 0.07y = 360

0.16y - 0.07y = 360

0.09y = 360

y = 4000

So, Stefan borrowed $4000 on his student loan. Using equation (a), we can find the amount he borrowed on his car loan:

x = 2y = 2(4000) = 8000

Therefore, Stefan borrowed $8000 on his car loan and $4000 on his student loan.

The sample variance is 2482.6375 and the sample standard deviation is 49.79 (rounded to four decimal places). The sample variance and standard deviation can be calculated using the following formula:

Sample variance:

s^2 = (1 / (n-1)) * ∑ (x_i - x)^2

Sample standard deviation:

s = √(s^2)

Where:

x_i is each data point,

x is the sample mean,

n is the number of data points,

∑ represents the sum of all terms.

First, we need to calculate the sample mean:

x = (86 + 102 + 130 + 160 + 180 + 195 + 135 + 145 + 214 + 105 + 145 + 154 + 153 + 135 + 87 + 99 + 94 + 119 + 129) / 20 = 140.95

Next, we can use the sample mean to calculate the sample variance:

s^2 = (1 / (20-1)) * ( (86-140.95)^2 + (102-140.95)^2 + (130-140.95)^2 + (160-140.95)^2 + (180-140.95)^2 + (195-140.95)^2 + (135-140.95)^2 + (145-140.95)^2 + (214-140.95)^2 + (105-140.95)^2 + (145-140.95)^2 + (154-140.95)^2 + (153-140.95)^2 + (135-140.95)^2 + (87-140.95)^2 + (99-140.95)^2 + (94-140.95)^2 + (119-140.95)^2 + (129-140.95)^2)

Finally, we can take the square root of the sample variance to find the sample standard deviation:

s = √(s^2) = √(2482.6375) = 49.79
