Answer:

Step-by-step explanation:

you want maximum height reached?

\frac{dy}{dt} =46-32t\\\\at max. height velocity=0\\ 0=46-32t\\32 t=46\\t=46/32=23/16\\y=t(46-16t)\\ at t=\frac{23}{16} \\ y=\frac{23}{16}(46-16*\frac{23}{16} )\\\\y=\frac{529}{16} ft

Answer:

-157.87

Step-by-step explanation:

1) the rules are:

log_a(bc)=log_ab+log_ac;

and

log_ab^c=c*log_ab.

2) according to the rules above:

log_7(yz^8)=log_7y+8log_7z=-6.19-8*18.96=-157.87.

25 POINTS!
lubasha [3.4K]
To solve this you'll plug in the ordered pairs and if the answer is equal then it is the answer.

A: 2 = 3(0) - 2
     2 = 0 - 2 
     2 ≠ -2

B: 1 = 3(1) - 2
     1 = 3 - 2
      1 = 1

C: 1 = 3(-3) - 2
      1 = -9 - 2
       1 ≠ -11

D: 0 = 3(2) - 2
     0 = 6 - 2
     0 ≠ 4

So the answer choice B is the solution to the given equation.

Hope this helps :)

Simplify sin θ / square root 1 - sin^2 θ
Soloha48 [4]

Recall that

\cos^2\theta+\sin^2\theta=1

which means

\dfrac{\sin\theta}{\sqrt{1-\sin^2\theta}}=\dfrac{\sin\theta}{\sqrt{\cos^2\theta}}

Now, \cos\theta could be positive or negative, which means \sqrt{\cos^2\theta}=|\cos\theta|. If we specifically knew the sign of \cos\theta was positive, then we can simplify and write

\dfrac{\sin\theta}{\sqrt{1-\sin^2\theta}}=\dfrac{\sin\theta}{\cos\theta}=\tan\theta

or if it's negative,

\dfrac{\sin\theta}{\sqrt{1-\sin^2\theta}}=\dfrac{\sin\theta}{-\cos\theta}=-\tan\theta
