40 goes into 280 7 times to figure this out just simply divide 280/40
(X-4)-(y+5)=5.4 value of f(3)
Answer:
Step-by-step explanation:
In Problem 6, 3/x = tan 30 degrees, or x/3 = 1 / (tan 30 degrees), or
x = 3 / (tan 30 degrees). Using a calculator: x = 3 / (0.449) = 6.68 units
In Problem 9, we begin by finding the length of the hypotenuse of the upper triangle: sin 60 degrees = 9√3 / hypotenuse, or
hypotenuse = 9√3/ (√3 / 2) = 9/2. Then the hypotenuse of the 45-45-90 triangle is 9/2. Thus, cos 45 degrees = x / (9/2), or
2x √3
---- = -------
9 2
9√3
Cross-multiplying, we get 4x = 9√3, so that x = -------------

Answer:
Marry's seat is units far from Betty's seat
Step-by-step explanation:
We are given that Class of Math is mapped on a coordinate grid and center point of the hall is at origin.
Coordinates of Mary's seat are (2,2) and Coordinates of Betty's seat are (6,7). We have to find how far is Mary's seat to Betty's seat. In order words, we have to find the distance between Marry's seat and Betty's seat.
Remember that whenever the coordinates of two points are given, the distance between them is calculated using the distance formula. The distance between two points and is given by distance formula as:
Here, the points with subscript 1 are initial points (2,2) and the point with subscript 2 are final points (6,7). Using these values in the formula, we get:
This means, Marry's seats is units far from Betty's seat
