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 :)

Eight students are competing for 1st, 2nd, 3rd, and 4th violin chair in the school’s orchestra. How many different ways can all
liubo4ka [24]

There are eight students. Each student is competing for 1st, 2nd, 3rd and 4th violin chair. We will use permutation to solve this problem.

When we have 'n' items and we want to find the number of ways 'k' items can be ordered. Then we use the permutation formula which states:

^nP_{k}=\frac{n!}{(n-k)!}

Therefore,

=^8P_{4}=\frac{8!}{(8-4)!}

=\frac{8!}{(4)!}

= \frac{8 \times 7\times 6\times 5\times 4!}{4!}

={8 \times 7\times 6\times 5}

= 1680

Therefore, in 1680 different ways can all four chairs be filled.
