Ineed some i will reward im frffr the y-value for y = cos(x) when x = -90° is 0. true false for what value(s) of x does sin(x) = 1? -90° 270° all of the above none of the above

1. True

2. -90 and 270 are the same position on the unit circle, so none of the above

1) The answer is true

y=cos(x)

0=cos(-90)

0=0

2) the answer is none of the above

sin(x)=1

sin(-90)= -1

sin(270)= -1

they both equal -1 and not 1

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
