The water pressure on mustafa as he dives is increasing at a rate of 0.992 atmospheres per meter. what is the rate of increase in water pressure in atm/km

Step-by-step explanation:

The water pressure on Mustafa as he dives in increasing at a rate of 0.992 atmospheres per meter.

We have to calculate the ratio increase in pressure of water in atm/km

Since rate of change of pressure is in atm/meter

so we will convert meter to km.

      [since 1 km = 1000 meter]

now  

= 0.992 × 10³

=

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
