If you accidentally measure 10 ml of a seawater sample instead of 5 ml but did not realize your error, would you still get appro

ximately the same calculated salinity or would it be different? If different, would you get a higher or lower salinity? Explain.

The result would be different. For if only 5ml instead of 10ml were measured, the salinity degree of the solution would be lower. It is possible to measure by a formula the concentration of solute and solvent contained in that amount of solution. C = M / V where C is the concentration, m is the mass of the solute and V is the volume of the solution.

kiruha [24]

Answer:

k = -7

Explanation:

Given

f(x) = 5^x through (0,1) and (1,5)

g(x) = 5^x + k through (0,-6) and (1,-2)

Required

Determine the value of k if f(x) is translated vertically down

To get the value of k, we perform the following operations.

For (0,-6) --- Substitute 0 for x and -6 for g(x) in g(x) = 5^x + k

g(x) = 5^x + k

-6 = 5^0 + k

-6 = 1 + k

k + 1 = -6

k = -6 - 1

k = -7

For (1,-2) --- Substitute 1 for x and -2 for g(x) in g(x) = 5^x + k

g(x) = 5^x + k

-2 = 5^1 + k

-2 = 5 + k

k+5 = -2

k= -2-5

k = -7

To further show that k = -7, we have the following:

f(x) = 5^x

When translated downward by 7 units, the function becomes

g(x) = f(x) - 7

Recall that: g(x) = 5^x + k and f(x) = 5^x

So, we have:

5^x + k = 5^x - 7

Subtract 5^x from both sides

5^x - 5^x + k = 5^x - 5^x + 7

k = -7

In terms of the total global supply of water, how much of it is in circulation (producing storms, precipitation events, related
Dima020 [189]

Answer:

The total amount of water on the planet that is present in the <em>atmosphere</em> at any given time is about 0.001% of the total water found on Earth. This atmospheric water is responsible for all storms.

If by in storage we mean in <em>groundwater</em> then the percentage would be 1.69.

Explanation:

The overwhelming majority of all water on our planet resides in the <em>oceans</em>. These hold about 96.5% of the total.

If we only consider freshwater (water with no salt) then the greatest storage areas are <em>ice caps</em>, <em>glaciers</em>, and <em>groundwater aquifers</em>.

Describe the tilt of the earth's axis during winter in the northern hemisphere.​
Vsevolod [243]

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
