Sydney is playing a game on a map with a marked grid. To start, she places a game piece at (1, 4). She moves 3 units east and 2

Anastasy [175]

Answer:

(7, 8)

Step-by-step explanation:

If Sidney places each piece 3 units east and 2 units north of the last one, we can figure out which coordinate comes first by subtracting the position of the second piece (S) by the position of the first piece (F):

$S - F = (4,6) - (1,4) = (3,2)$

We can conclude that coordinates are in the (East, North) format.

Therefore, the location of the third piece (T) is:

$T = S(E,N) +(3,2)= (4,6)+(3,2)\\T = (7,8)$

1 litre is approximately 1.75 pints, 1 gallon = 8 pints, calculate the approcimate number of gallons that are equal to 48000cm3

Umnica [9.8K]

Answer:

$10.5\ gal$

Step-by-step explanation:

we know that

$1,000\ cm^{3} =1\ l$

$1\ l=1.75\ pints$

$1\ gal=8\ pints$

we have

$48,000\ cm^{3}$

step 1

Convert to liters

$48,000\ cm^{3}=48,000/1,000=48\ l$

step 2

Convert to pints

$48\ l=48*1.75=84\ pints$

step 3

Convert to gallons

$84\ pints=84/8=10.5\ gal$

Six years ago annabelle was twice as old as jason was. now, annabelle is four years older than jason. how old is jason now?

baherus [9]

Now: a=j+4
6 years ago: Anabelle: a-6; Jason: j-6

$a-6=2(j-6) \\ a=2j-12+6 \\ a=2j-6 \\ \\ j+4=2j-6 \\ 4+6=2j-j \\ j=10 \\ \\ a=2(10)-6 \\ a=14$

100 points!!! Pre calculus. I need helpppppppppp

Fantom [35]

Answer:

We have function,

$y = 3 - 6 \sin {}^{} (2x + \frac{\pi}{2} )$

Standard Form of Sinusoid is

$y = - 6 \sin(2x + \frac{\pi}{2} ) + 3$

Which corresponds to

$y = a \sin(b(x + c)) + d$

where a is the amplitude

2pi/b is the period

c is phase shift

d is vertical shift or midline.

In the equation equation, we must factor out 2 so we get

$y = - 6(2(x + \frac{\pi}{4} )) + 3$

Also remeber a and b is always positive

So now let answer the questions.

a. The period is

$\frac{2\pi}{ |b| }$

$\frac{2\pi}{ |2| } = \pi$

So the period is pi radians.

b. Amplitude is

$| - 6| = 6$

Amplitude is 6.

c. Domain of a sinusoid is all reals. Here that stays the same. Range of a sinusoid is [-a+c, a-c]. Put the least number first, and the greatest next.

So using that<em> rule, our range is [6+3, -6+3]= [9,-3] So our range</em> is [-3,9].

D. Plug in 0 for x.

$3 - 6 \sin((2(0) + \frac{\pi}{2} )$
