Can someone please help me with this math problem

Your answer is D

Step-by-step explanation:

It's receding, or going down, leaving, etc., which means it's going to be a negative number, which eliminates 2 answers because your number has to be -.25.

You can't have negative levels of water, and it also said that there are 2 meters of water. This eliminates C, leaving only D left.

Option D) d (t ) = -0.25t + 2

Step-by-step explanation:

Given the water level covering a road after a rainstorm of 2 meters, for which the water level recedes at a rate of 0.25 meters per hour:

We can express the depth, d, of the water as a linear function of the time, t, in hours elapsed from the end of the rainstorm as:

d (t ) = -0.25t + 2

The receding rate has a negative value since it represents how the water level decreases over time.

Therefore, the correct answer is Option D: d (t ) = -0.25t + 2

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
