What is the slope of the line passing through the points (1, 5) and (4, 1)?
To find the slope of the line that passes through the points (1, 5) and (4, 1), we use the formula for the slope (m) between two points (x1, y1) and (x2, y2): m = (y2 – y1) / (x2 – x1) In this case, we can identify: (x1, y1) = (1, 5) (x2, y2) […]
Find a formula for the nth term of the arithmetic sequence 32, 36, 40, 44
To find the formula for the nth term of the given arithmetic sequence, we first need to identify the first term and the common difference. The first term of the sequence (a1) is 32. Next, to find the common difference (d), we subtract the first term from the second term: d = 36 – 32 […]
What is the area of a triangle with a base of 8 and a height of 6?
To find the area of a triangle, we use the formula: Area = (base × height) / 2 In this case, the base of the triangle is 8 units and the height is 6 units. Plugging these values into the formula gives us: Area = (8 × 6) / 2 If we calculate that, we […]
If angle BAC measures 56, what is the measure of angle BDC: 28, 34, 56, or 112?
