On a mild Saturday morning while people are working inside, the furnace keeps the temperature inside the building at 23degreesC. At noon the furnace is turned off, and the people go home. The temperature outside is a constant 14degreesC for the rest of the afternoon. If the time constant for the building is 3 hr, when will the temperature inside the building reach 18degreesC? If some windows are left open and the time constant drops to 2 hr, when will the temperature inside reach 18degreesC?

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

-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
