2e^-0.07t=8 divide both sides by 2
e^ (-.0.07t) = 4 take the Ln of both sides
Ln e^(-0.07 t) = Ln 4 and by a log property we can write
-0.07 t = Ln 4 divide both sides by -0.07
t = Ln 4 / -0.07 ≈ -19.8
I assume that you want to solve for x
So we have
tan (70) = x / 7 multiply oth sides by 7
7 * tan (70) = x ≈ 19.23
Excellent explanation, Guest.....why don't you register and become a member???
We need more people like you on here!!!!
Yeah MJ, ICE CREAM......sounds good.....
Here you go.......have some on me.......!!!!!
Always glad to help.......good luck....!!!!
C - changing the deposit to $40
The y intercept represents the deposit charge of $50.....it's known as the "fixed cost"......charging either more (or less) for the deposit will change the y intercept
Congrats, Omi and asinus......!!!!!
3 pi / 2 lies exactly between pi and 2pi
pi = 180° and 2pi = 360° so 3pi/2 = 270°
Is this what you are asking???
Note that sin (3 pi/ 2) = -1 and 3pi/2 lies in the requested interval
