Answer:
8 feet
Step-by-step explanation:
you use pythagoras so you do 6² + 4² =52. then you square root 52 which is 7.2 so she needs 8 feet.
Answer:
Water temperature in an ocean varies inversely to the water’s depth. Between the depths of 250 feet and 500 feet, the formula
T
=
14
,
000
d
gives us the temperature in degrees Fahrenheit at a depth in feet below Earth’s surface. Consider the Atlantic Ocean, which covers 22% of Earth’s surface. At a certain location, at the depth of 500 feet, the temperature may be 28°F.
Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
Answer:
256
Step-by-step explanation:
The intial value should be where it started which in this case would be when
t = 0
So if you make t = 0
h(0) = 16(0)^2+96(0)+256
h(0)= 256
