Me plz im very confused for what value(s) of x does sin(x) = 1? -90° 270° all of the above none of the above 2 points question 66 the y-value of y = sin(x) when x= -360° is y = 0. true false 2 points question 67 the y-value for y = cos(x) when x = -90° is 0. true false 2 points question 68 for what value(s) of x does cos(x) = -1? -360° 360° all of the above none of the above 2 points question 69 the y-value of y = tan(x) when x = -90° and x = 90° is 0. true false 2 points question 70 what is the y-value for y = tan(90°)? - negative one-half one-half 1 undefined

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
