Rosa is making a poster that has a rainbow as part of the design. Using a string and a pencil she makes a compass. She draws a semicircle that has a radius of 18 inches. Using the same center point, she draws another semicircle that has a radius of 12 inches.

the distance between point a and point b is 6 units

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

current in the circuit at time t is /, then the power delivered to the resistor is
