An empty spherical balloon is being filled with air at the constant rate of 2 cm3/sec. How fast is the surface area of the balloon increasing after 10 seconds? Repeat for 15 seconds and 30 seconds.

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

it has the same slope and a different y-intercept

hope this : )

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

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
