The function f(x)=2/3x+2 can be formed by shifting the function y=2/3x in which way?
a. vertical shift down 2
b. horizontal shift to the right 2
c. vertical shift up 2
d. horizontal shift to the left

If a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin(a+b).

Me because some of question i don’t understand

Acylinder with a base diameter of x units has a volume of jxcubic units which statements about the cylinder are true? check all that apply. the radius of the cylinder is 2 x units. the radius of the cylinder is 2x units. the area of the cylinder's base is 200 square units. the area of the cylinder's base is a square units. the height of the cylinder is 2x units. the height of the cylinder is 4x units. mark this and return save and exit next submit
