Explanation:
Surface_Area_Cube: 2(Length x Width + Height x Length + Height x Width)
<h3 /><h3><u>Given sides</u>:</h3>- length: 10ft
- width: 7.5ft
- height: 12ft
- 2(10 x 7.5 + 12 x 10 + 12 x 7.5)
- 2(75 + 120 + 90)
- 2(285)
- 570 ft²
Answer:
k = -3 or 5
Step-by-step explanation:
The given parameters are;
The line extends from points (-1, 1) to point (2, k)
The length of the line = 5 units
The formula for the length, l, of a line given its coordinates can be found by the following formula;
Therefore, we have;
Which, by squaring both sides, gives;
25 = (k - 1)² + (2 - (-1))² = (k - 1)² + (2 + 1)² = (k - 1)² + 3²
25 = (k - 1)² + 3² = k² - 2·k + 1 + 9
25 - 25 = 0 = k² - 2·k + 1 + 9 - 25 = k² - 2·k - 15
0 = k² - 2·k - 15
0 = (k +3) × (k - 5)
Therefore, k = -3 or 5
When k - -3, we have;
When k = 5, we have;
