Answer: A. $10.20

explanation:
if you’re not paying 15%, then you’re paying 85%
(100-15 = 85)
so
.85 * 12 = 10.20

What is the value of<br> –4.00<br> –0.25<br> 1.51<br> 2.41

soldier1979 [14.2K]

For this case we must resolve the following expression: $log_ {0.5} (16)$

We have to:

$log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}$

The base change rule can be used if a and b are greater than 1 and are not equal to x.

We substitute the values in the base change formula, using $b = 10$

$\frac {log (16)} {log (0.5)} = - 4$

Answer:

-4

Option A

What are the amplitude, period, and phase shift of the given function? f(t)=-1/2sin(3t-2pi)

Romashka [77]

Answer:

The $amplitude=|A|=\frac{1}{2}$ , $period=3$ and $\text{phase shift}=\frac{2\pi}{3}$ .

Step-by-step explanation:

The given function is

$f(t)=-\frac{1}{2}\sin (3t-2\pi)$ .... (1)

The general form of sine function is

$F(t)=A\sin (Bt-C)+D$ ....(2)

where, |A| is the amplitude, B is period, D is the vertical shift (up or down), and C/B is used to find the phase shift.

On comparing (1) and (2), we get

$A=-\frac{1}{2}$

$B=3$

$C=2\pi$

$D=0$

So,

$amplitude=|A|=\frac{1}{2}$

$period=3$

$\text{phase shift}=\frac{2\pi}{3}$

Therefore $amplitude=|A|=\frac{1}{2}$ , $period=3$ and $\text{phase shift}=\frac{2\pi}{3}$ .

Margot purchases book tees from the warehouse and marks up those prices by 20% for retail sale when tease go on sold for more th

rusak2 [61]

No she's not correct,,,
If the teas are $50 to start with 20% up from $50 is $62.50
if she counts down 20% down from that it wouldn't be $50 but be $40.
So she would not break even.
