Answer:
Options (1), (2), (3) and (4)
Step-by-step explanation:
By applying the sine and cosine rules in the given triangle,
sinθ = 
cosθ = 
cos(30°) = 
= 
= 
sin(30°) = 
= 
= 
cos(60°) =
=
=
sin(60°) = =
=
=
Options (1), (2), (3) and (4) are the correct options.
The equation of the graph is given as y = (2/5)x - 5.
You have to figure out which of the choices equals the equation given,
y = (2/5)x - 5.
You could solve each of the answer choices for y, but since each choice is in the format x - (m)y = b, you can put the given equation in that format too.
Answer:
vertex=(1,-3)
y-intercept=(0,-2)
x-intercept=(1,+\sqrt{3},0)
axis of symmetry= 1
Of course!
Cube: side length * side length * side length
So if it's a 6x6x6 cube, it's 6*6*6 = 216
Rectangular Prism: side length * side height * base width
So if it's a 6x7x8 prism, it's 6*7*8 = 336
Cylinder: π * (radius squared) * height
So if the base's radius is 6 and the height is 7, it's π*6^2*7 = 252π
