If you are looking for how many DVDs and CDs Satchi can buy then Satchi would be able to buy 2 DVDs and 3 CDs for a cheap price or 3 DVDs and 2 CDs for a more expensive price.

Budget: $45

DVDs: CDs:
$9 $7

Add $9 + $7 = $16
Add again, which would equal $32
You can either buy 2 DVDs and 3 CDs which is $32 + $7 = $39 or 3 DVDs and 2 CDs which is $32 + $9 = $41

Point B has coordinates ​(2​,1​). The​ x-coordinate of point A is negative 1. The distance between point A and point B is 5 unit
Gwar [14]

Answer:

A = (-1,5) or  (-1,-3)

Step-by-step explanation:

A = (-1,y)    B = (2,1)

 

(Distance from A to B) = √[(-1-2)² + (y-1)²] = 5

                                    =√[9 + y² - 2y + 1] = 5

Squaring on both sides

                                     =  y² - 2y + 10 = 25

                                       =y² - 2y -15 = 0

                                      = (y-5)(y+3) = 0

                                         y = 5 or -3

Therefore, A = (-1,5) or  (-1,-3)

Help please!!<br> asap no wrong answers<br> will give the crown symbol
Svetllana [295]

Answer:

4Hz

Step-by-step explanation:

Standard form of a sine or cosine function,

y = acos(b(x+c))

where a is the amplitude, b is the value to find the period. and c is the phase shift.

Period = \frac{2\pi}{b}

From the equation given in the question,

y = 3cos(8\pi \: t +  \frac{\pi}{2} ) \\ y = 3cos(8\pi(t +  \frac{1}{16} )) \:  \: (factorising \: 8\pi \: out)

We can see:

Amplitude = 3,

Period = \frac{2\pi}{8\pi} = 1 / 4

Phase Shift = 1 / 16

Now we want to find the frequency.

Frequency = 1 / Period

= 1 / (1/4)

= 4Hz
