The radius of a sphere, r, is given by the formula below, where a is the surface area of the sphere. a spherical balloon has a maximum surface area of 1,500 square centimeters. use the given formula to write a function, r(s) that models the situation. then, use the function to predict how the radius of the balloon changes as the balloon is inflated.

answer: a and b

step-by-step explanation:

answer: 298143

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
