A sine function had an amplitude of 3, period of 6pi, horizontal shift of 3pi/2, & vertical shift of -1.

Simora [160]

Answer: $\bold{y=\dfrac{1}{2}}$

Step-by-step explanation:

f(x) = A sin (Bx - C) + D

amplitude = |A|
period = $\dfrac{2\pi}{B}$
phase shift = $\dfrac{C}{B}$
vertical shift = D

A

amplitude of 3 is given so 3 = |A| → A = ± 3, since it is stated that this is a positive function, then A = 3

B

period of 6π is given so $6\pi=\dfrac{2\pi}{B}\quad \rightarrow \quad B=\dfrac{2\pi}{6\pi}\quad \rightarrow \quad B=\dfrac{1}{3}$

C

$\text{phase shift is given as}\ \dfrac{3\pi}{2}\ \text{so}\ \dfrac{3\pi}{2}=\dfrac{C}{\frac{1}{3}}\quad \rightarrow\quad \dfrac{(\frac{1}{3})3\pi}{2}=C\quad \rightarrow\quad \dfrac{\pi}{2}=C$

D

vertical shift of -1 is given so -1 = D

Now, substitute the values of A, B, C, and D into the formula (above):

$f(x) = 3\ sin \bigg(\dfrac{1}{3}x - \dfrac{\pi}{2}\bigg) - 1$

Next, solve when x = 2π

$f(2\pi) = 3\ sin \bigg(\dfrac{1}{3}(2\pi) - \dfrac{\pi}{2}\bigg) - 1$

$= 3\ sin \bigg(\dfrac{2\pi}{3} - \dfrac{\pi}{2}\bigg) - 1$

$= 3\ sin \bigg(\dfrac{4\pi}{6} - \dfrac{3\pi}{6}\bigg) - 1$

$= 3\ sin \bigg(\dfrac{\pi}{6}\bigg) - 1$

$= 3\ \bigg(\dfrac{1}{2}\bigg) - 1$

$=\dfrac{3}{2}-\dfrac{2}{2}$

$=\dfrac{1}{2}$

Eduardwww [97]

Answer:

option C 2*x + 3*y = 7.20

4 *x + 2*y = 8.80

1.4

Step-by-step explanation:

PART A

Steve

2lbs of grapefruit

3lbs oranges for $7.20

kennedy

4lb grapefruit

2lb oranges for $8.80

price 1 pound grapefruit x

1 pound oranges y

Then for steve

2*x + 3*y = 7.20

for kennedy

4 *x + 2*y = 8.80

PART B

now we have to find y from above equations

2x + 3y = 7.20 multiply by 2 on both sides 4x + 6y = 14.4

4x + 2y = 8.80

next by substracting the above two equations we get

6y - 2y = 14.4 - 8.80

4y = 5.6

y = 1.4

19. Each deli sandwich made uses :- pound of turkey Tyler started with 318 pounds of turkey and now has 1 3 pounds left. How man

sweet [91]

So convert to inprompery fractions
3 and 7/8=3+7/8=24/8+7/8=31/8
1 and 5/8=1+5/8=8/8+5/8=13/8

so each uses 1/4 cup
1/4=2/8
so
find the difference between 31/8 and 13/8

$\frac{31}{8}-\frac{13}{8}$ = $\frac{18}{8}$
so find how many 2/8 goes into 18/8
2/8 times what=18/8
multily both sides by 8/2 to clear faction
what=144/16=36/4=9/1=9
I made 9 sandwitches
