Answer: the answers are c and d
Step-by-step explanation: only these combinations would form right triangles because the way other combinations are too small or too large to actually accommodate for the remaining number in the problem. The squares of 5, 12, and 13 are 25, 144, and 169, meaning they form a perfect right triangle. The next sequence is 36, 85, 77, and the squared rearranged version is 1,296, 5,929, and 7,225, meaning they also form a right triangle.
Answer:
d.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Hi there!
We're given the equation y=-75x-50, which represents a submarine DESCENDING towards the ocean floor, where y is the depth in feet, and x is the number of minutes the submarine is descending
Since the submarine is DESCENDING, we can immediately eliminate A and C, which talk about the submarine ASCENDING
That leaves B and D
Looking at the given equation, y=-75x-50, -75 is the slope, or rate of change, and -50 is the y intercept, or the "beginning" (where the equation will "start")
Therefore, the submarine will start at -50 feet, or 50 feet below sea level
As x is the number of minutes the submarine is descending, that means that if the submarine travels 1 minute, it will descend 75 feet (-75*1=-75), at 2 minutes, it'll descend 150 feet (-75*2=-150), and so on
So that means the submarine must be descending at a rate of 75 feet per minute
Therefore D is the correct answer
Hope this helps! Good luck on your assignment :)
