The inverse is f(x)=2x-1. Because the inverse operation of addition is subtraction.

Select the correct answer.<br><br> Which expression is equivalent to sin^2x-sinx-2/sinx-2?

ladessa [460]

Answer:

Step-by-step explanation:

We are given:

$\displaystyle \frac{\sin^2(x)-\sin(x)-2}{\sin(x)-2}$

To make it simpler and more clear, we can let u = sin(x). So:

$\displaystyle \frac{u^2-u-2}{u-2}$

Now, it becomes obvious that we can factor, which produces:

$\displaystyle =\frac{(u-2)(u+1)}{u-2}$

Cancel:

$=u+1$

And substituting back:

$=\sin(x)+1$

Hence, our answer is A.

A car slows down at -5.00 m/s2 until it comes to a stop after traveling 15.0 m. How much time did it take to stop.

professor190 [17]

Answer:

2.45 seconds to the nearest hundredth.

Step-by-step explanation:

Acceleration a = -5, distance s = 15, time = ?.

Final velocity = v = 0.

We need to use the equations of motion under constant acceleration.

v^2 = u^2 + 2as where u is the initial velocity

0 = u^2 + 2*-5*15

u^2 = 150

so u = √150

Now we use v = u + at:

0 = √150 - 5t

t = √150/5

t = 2.45 seconds.
