Answer:

Step-by-step explanation:

polar coordinates  =  R ( 8 ) , θ = 1.85π ( 1.85 x 180 = 333° )

x - coordinate  = r cosθ = 8 cos333

= 7.13

Y-coordinate = r sinθ = 8 sin 333

= - 3.63.

(7.13 , - 3.63 )

Option a is the answer.

dangina [55]

Answer:

She bought 12 gallons.

41.49 / 3.68 = 11.2

*I rounded it to 12 because you can't go below 11.2*

12 x 3.68 = 41.49

What is the y-intercept of the function f(x)=4 - 5x? (Hint: use the commutative property)
Tom [10]

Answer:

Therefore the y-intercept of the function is 4.

Step-by-step explanation:

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

y-intercept: The line or function which intersect at y-axis. So when the line intersect at y-axis, X coordinate is zero.

So in the given Function Put x = 0 we will get the y-intercept

f(x)= 4-5x

Put x =0

f(0)= 4-5\times 0

f(0)= 4-0=4

Therefore the y-intercept of the function is 4.
