The flash unit on a camera operates by storing charge on a capacitor and releasing it suddenly when the flash is set off. the following data describe the charge q remaining on the capacitor (measured in microcoulombs, µc) at time t (measured in seconds). t 0.00 0.02 0.04 0.06 0.08 0.10 q 100.01 85.84 73.67 63.23 54.27 46.58 (a) use a graphing calculator or computer to find an exponential model for the charge. (round your coefficients to three significant digits.)

-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

step-by-step :

probably .5

i can on others if necessary.
