Answer: 75 hours

Step-by-step explanation:

Assuming you meant decreasing... you find out the span between 212.5 and 25 which is 187.5 and then divide it by 2.5 (which is the change)

X^2 + Y^2 +ax + 2y + 3 = 0<br><br> What number is this equation the equation of a circle?
Sav [38]

Answer:

Eq: (x+a/2)²+(y+1)²=(a²-8)/4

Center: O(-a/2, -1)

Radius: r=0.5×sqrt(a²-8)

Mandatory: a>2×sqrt(2)

Step-by-step explanation:

The circle with center in O(xo,yo) and radius r has the equation:

(x-xo)²+(y-yo)²=r²

We have:

x²+y²+ax+2y+3=0

But: x²+ax=x²+2(a/2)x+a²/4-a²/4= (x+a/2)²-a²/4

And

y²+2y+3=y²+2y+1+2=(y+1)²+2

Replacing, we get:

(x+a/2)²-a²/4+(y+1)²+2=0

(x+a/2)²+(y+1)²=a²/4-2=(a²-8)/4

By visual inspection we note that:

- center of circle: O(-a/2, -1)

- radius: r=sqrt((a²-8)/4)=0.5×sqrt(a²-8). This means a²>8 or a>2×sqrt(2)

!. PLEASE HELP!!! will mark brainliest!!
NeX [460]

Matter exists in three states; <em>solid, liquid and gas.</em>

The statement that corrects the error in his table is:

<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume. </em>

<em />

<em />

Looking at the table, we have the following observations.

  • <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
  • <em>The liquid column is properly cataloged</em>
  • <em>The gas column shows a definite shape</em>

<em />

Solid has definite shape, while gas doesn't.

To make corrections, Marcus needs to switch the gas and the solid column.
