Answer:
1020–1029 kg/m3
Step-by-step explanation:
The density of seawater at the surface of the ocean varies from 1,020 to 1,029 kilograms per cubic meter.
The density of seawater is a function of temperature, salinity, and pressure.
To measure the density of ocean water a sample of sea water is collected and brought into the laboratory to be measured. Salinity, temperature and pressure are measured to find density. The formula for measuring density is p(density) = m(mass) / V(volume).

Answer:
42.5 square units
Step-by-step explanation:
To solve, we can split this shape up into 4 known shapes:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 5 unit triangle
3.5 unit by 9.0 unit rectangle
Now let's solve these areas:
2 x 2 = 4 / 2 = 2
2 x 2 = 4
2 x 5 = 10 / 2 = 5
3.5 x 9.0 = 31.5
Then add all these values together:
2 + 4 + 5 + 31.5 = 42.5
Answer:
D. 93
Step-by-step explanation:
Given:
m<1 = 28°
m<6 = 65°
m<5 = 65°
Required:
m<MAX
Solution:
m<MAX = m<1 + m<5 (angle addition postulate)
Substitute
m<MAX = 28° + 65°
m<MAX = 93°
Answer:
Given functions,
Since, by the compositions of functions,
1. (g◦f)(x) = g(f(x))
Since, (g◦f) is defined,
If 3 - x² ≥ 0
⇒ 3 ≥ x²
⇒ -√3 ≤ x ≤ √3
Thus, Domain = [-√3, √3]
2. (f◦g)(x) = f(g(x))
Since, (g◦f) is defined,
If x ≥ 0
Thus, Domain = [0, ∞)
3. (f◦f)(x) = f(f(x))
Since, (f◦f) is a polynomial,
We know that,
A polynomial is defined for all real value of x,
Thus, Domain = (-∞, ∞)
