Ascuba diver dove from the surface of the ocean to an elevation of
feet at a rate of
-18.6 feet per minute. after spending 14.5 minutes at that elevation, the diver ascended to
an elevation of -28 feet. the total time for the dive so far was 21 minutes. what was
the rate of change in the diver's elevation during the ascent? round your answer to the
nearest hundredth.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
