A scuba diver descends farther down into the ocean from an initial depth of 15.2 feet below sea level. The scuba diver descends at a constant rate for 2 1/2 minutes and reaches a depth no more than 46.7 feet below sea level. What is the maximum rate, r, that the scuba diver may descend? r ≤ 24 19/25
r ≥ 24 19/25
r ≤ 12.6
r ≥ 12.6

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

560

hope this : )

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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.
