Mark and Luke were calculating the surface area of a cylinder of height 28 ft and radius 9ft . Mark found the surface area to be 565.20 square feet , and Luke found it to be 2,091.24 square feet. Who is correct? Explain your answer.

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
