What is the range of y = sin θ ? [–1, 1] [0, ∞) all real numbers 2π

Range of the given function is:

                              [-1,1]

We know that the graph of a sine function i.e.

is a continuous curve that repeats itself after a fixed interval of 2π i.e. fundamental period of function is: 2π.

Also, the minimum value of the function is: -1

and the maximum value of the function is 1

and all the other value lie between these.

Hence, the range of y=sinθ is: [-1,1]

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
