Given that sinA= 3/7, cos⁡B=-2/5, and that both A and B are in quadrant II, find cos(A - B). Simplify it to a single value, leaving it in the form of a rational number.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
