Y=e^-0.3t would better be written as   y<span>=e^(-0.3t), because you want to emphasize that the exponent of "e" is -0.3t.  Enclose the expon. within ( ), ps.

Since the expo is neg, this is expo. decay, and the rate is 0.3 per time period.

For example, if y is = to .5 right now, the next value, after 1 time period, will be 
.5(.3) = .15.</span>

Round Ed to the nearthest tenth and answer now question
Vikki [24]

Answer:

y = 9.1

Step-by-step explanation:

y can be found using the Law of sines as explained below:

m < Y = 106°

m < X = 58°

WY = x = 8

WX = y = ?

Thus,

\frac{x}{sin(X)} = \frac{y}{sin(Y)}

\frac{8}{sin(58)} = \frac{y}{sin(106)}

\frac{8}{0.848} = \frac{y}{0.961}

Multiply both sides by 0.961 to solve for y

\frac{8}{0.848}*0.961 = \frac{y}{0.961}*0.961

\frac{8*0.961}{0.848} = y

\frac{8*0.961}{0.848}*0.961 = y

9.07 = y

y = 9.1 (to the nearest tenth)
