0.5 x 4 = 2 feet / 2 feet in 4 seconds
15 - 2 = 13
New depth: 13 feet
0.4 x 3 = 1.2 feet / 1.2 feet in 3 seconds
13 - 1.2 = 11.8
New depth: 11.8 feet
Substituting m for 9
h(9) = 9^2 - 3*9
h(9) = 81 -27
h(9) = 54
Third option!

Answer:
All real numbers
Step-by-step explanation:
Let's solve your inequality step-by-step.
−x2−6<0
Let's find the critical points of the inequality.
−x2−6=0
−x2−6+6=0+6(Add 6 to both sides)
−x2=6
−x2
−1
=
6
−1
(Divide both sides by -1)
x2=−6
x=±√−6(Take square root)
The heart beat rate is 70beats/minute with 80ml of blood pumped every beat. Then, the <span>volume of blood your heart pumps in one minute would be:
volume of blood per minute= volume per beat * beat per minute
</span>volume of blood per minute= 80ml/beat * 70beat/minute= 560ml/ minute<span>
</span>volume of blood per hour would be: 560ml/minute * 60 minute/hour= 33.600 ml/hour
