When the cosine of an angle (0) is 3/5 and the angle lies in quadrant 4, the exact value of the sine of that angle is -4/5.

To find the exact value of sin(0), we can utilize the Pythagorean identity, which states that \(sin^2(x) + cos^2(x) = 1,\) where x is an angle in a right triangle. Since the terminal side of the angle (0) is in quadrant 4, we know that the cosine value will be positive, and the sine value will be negative.

Given that cos(0) = 3/5, we can determine the value of sin(0) using the Pythagorean identity as follows:

\(sin^2(0) + cos^2(0) = 1\\sin^2(0) + (3/5)^2 = 1\\sin^2(0) + 9/25 = 1\\sin^2(0) = 1 - 9/25\\sin^2(0) = 25/25 - 9/25\\sin^2(0) = 16/25\)

Taking the square root of both sides to find sin(0), we have:

sin(0) = ±√(16/25)

Since the terminal side of (0) is in quadrant 4, the y-coordinate, which represents sin(0), will be negative. Therefore, we can conclude:

sin(0) = -√(16/25)

Simplifying further, we get:

sin(0) = -4/5

Hence, the exact value of sin(0) when cos(0) = 3/5 and the terminal side of (0) is in quadrant 4 is -4/5.

Step-by-step explanation:

The answer to the given question is option b. Skewed to the left.When the mean is less than the median, the distribution is usually skewed to the left. This means that the majority of the data are above the mean, and there is a long tail on the left side that drags the mean down.

When the mean is less than the median, the distribution is generally skewed to the left. This implies that most of the data is above the mean, and there is a long tail on the left side that drags the mean down.The shape of a distribution is determined by the relative frequencies of observations at each value. A symmetric distribution is one in which the frequencies are distributed evenly around the center of the distribution.

The mean and median are equal in a symmetric distribution.A skewed distribution is one in which the frequencies are unevenly distributed around the center of the distribution. A distribution can be skewed to the left or to the right, depending on the direction of the tail.A distribution is skewed to the left if there is a long tail on the left side of the distribution that drags the mean to the left of the median. This is often referred to as a negative skew.A distribution is skewed to the right if there is a long tail on the right side of the distribution that drags the mean to the right of the median. This is often referred to as a positive skew.

Therefore, when the mean is less than the median, the distribution is usually skewed to the left. This means that the majority of the data are above the mean, and there is a long tail on the left side that drags the mean down.

The length of arc QS is approximately 2.09 units.

The length of an arc of a circle:

Length of arc = (central angle / 360) × 2 × π × radius

Central angle is the angle in degrees formed by the two radii that define the arc and radius is the radius of the circle.

In this case, we are given that m∠QRS = 30 means that the central angle formed by radii QS and QR is 30 degrees.

We are also given that QR = 4 unit

The radius of the circle is also 4 units.

Substituting these values into the formula, we get:

Length of arc QS = (30 / 360) × 2 × π × 4

Simplifying and rounding to the nearest hundredth we get:

Length of arc QS ≈ 2.09

The length of arc QS is approximately 2.09 units.

An arc of a circle's length:

Arc length equals (central angle / 360) divided by 2 and radius.

Radius is the diameter of the circle, while central angle is the angle, in degrees, produced by the two radii that constitute the arc.

In this instance, we are told that mQRS = 30 denotes the centre angle of 30 degrees created by radii QS and QR.

Also stated is that QR equals 4 units.

The circle also has a radius of 4 units.

When these values are added to the formula, we obtain:

Arc length QS = (30 / 360) 2 4

Rounding to the closest hundredth and simplifying, we obtain:

Arc length QS = 2.09

Arc QS has a length of around 2.09 units.

Step-by-step explanation:

notebooks: 13×400=5200

desktop: 19×150=2850

The cost to buy 13 notebooks and 19 desktop computers is $8050

Cost of notebook computers = $400

Cost of desktop computers = $150 each

The cost to buy 13 notebooks and 19 desktop computers will be:

= 400(13) + 150(19)

= 5200 + 2850

= $8050

The cost to buy n notebooks and d desktop computers will be:

Answer: sqrt(61)

Step-by-step explanation:

For parts a) and c1), refer to the attached picture.

For part b), the distance formula is:

d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Using x1 = -1, y1 = -4, x2 = -6, y2 = 2:

d = sqrt[(-6 + 1)^2 + (2 + 4)^2] = sqrt[25 + 36] = sqrt(61)

Part c2) Another way to find the length of AB without using the distance formula is by drawing the line and measuring it according to the scale.

Part d) This will only work as long as the graph paper is accurately made, and the scale computation is done correctly. However, this will only give approximations, and will not give an exact answer when radicals are involved.

The personal banker given lending arrangement, the APR for your cousin's buddies who borrowed $20 and repaid $40 at the end of the month would be 120%

The annual percentage rate (APR) for your cousin's lending arrangement,  to make a few assumptions. That each lending transaction occurs on the first day of the month and is repaid on the last day of the same month. Based on these assumptions, calculate the effective APR as follows:

Calculate the interest charged for a $20 loan over one month:

Interest = $40 (repaid amount) - $20 (loaned amount) = $20

Divide the interest by the loan amount and multiply by 100 to get the monthly interest rate:

Monthly Interest Rate = (Interest / Loan Amount) ×100 = ($20 / $20) ×100 = 100%

Multiply the monthly interest rate by 12 to obtain the annual interest rate:

APR = Monthly Interest Rate ×12 = 100% ×12 = 120%

Answer:

The surface area of a pyramid can be calculated by adding the area of the base to the sum of the areas of the lateral faces. If the base of the pyramid is a regular polygon, the formula for the surface area is:

Surface Area = Base Area + (0.5 x Perimeter of Base x Slant Height)

The surface area of a cone can be calculated by adding the area of the base to the area of the lateral surface. The formula for the surface area of a cone is:

Surface Area = Base Area + (π x Radius x Slant Height)

In both formulas, the slant height is the distance from the apex (top point) to the base along a lateral face.

In a dataset or graph, outliers are extreme values that greatly deviate from the dominant pattern of values.

In order to identify the outlier, search for a value that is significantly greater or smaller than all the other values. Due to its extreme size compared to all other numbers, the number 267 is an outlier.

a value that "lies outside" (i.e., is significantly smaller or substantially bigger) most of the other values in a set of data For instance, both 3 and 85 in the scores 25, 29, 3, 32, 85, 33, 27 and 28 are "outliers".

A data point that is an outlier in a data graph or dataset you are dealing with is one that is extraordinarily high or extraordinarily low in comparison to the nearest data point and the rest of the nearby coexisting values.
