21000*0,2=4200 - discount 20%
21000-4200=16800 - cost with discount but wihout tax
16800*1.085=18228 - total cost

Determine the amplitude (A), period (P), and phase shift (PS) of the function f(x)= 3sin(x-4)+9

Tpy6a [65]

ANSWER

D.
$A=3,P=2\pi,PS=(4,9)$

EXPLANATION

The given function is

$f(x) = 3 \sin(x - 4) + 9$

Comparing to the general form of a trigonometric sine function,

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

$A=3$
The amplitude is absolute value of A

$|A| = |3| = 3$

$B=1$

The period is given by

$p = \frac{2\pi}{ B}$

$p = \frac{2\pi}{ 1} = 2\pi$

$C=4$

is a shift to the right of 4 units.

and

$D=9$

is an upward shift of 9 units

Therefore the phase shift is (4,9).

The correct answer is D

Please help i need to finish this!!

s2008m [1.1K]

Answer:

20 inches x 26 inches

Step-by-step explanation:

set up an equation: (2x)(x+7)=520

now just solve it

2x^2+14x=520

x^2+7x-260 = 0

factor: (x-13)(x+20)

x = 13 and -20

13 is the only one that works because you can't have a negative side length

13+7=20

13*2=26

lmk if you don't understand how to solve that equation

That is my question

Margarita [4]

Answer:

His total profit is $213.00

Step-by-step explanation:

He spent $90 on tires ($45x2), $255 on rims ($85x3), and $25 on headlights ($5x5), spending a total of $370.

He sold the tires for a total of $130 ($65x2), the rims for a total of $378 ($126x3), and the headlights for a total of $75 (15x5), a total of $583.

To find his final profit, you need to subtract what he spent from what he earned when he sold the items. ($583-$370= $213).
