Answer:

C) x=2 y=-1 z=3

Step-by-step explanation:

2x + y - z = 0

2(2) + (-1) - (3) = 0

0 = 0

x - y + z =6

2 - (-1) + 3 = 6

6 = 6

x + 2y + z = 3

2 + 2(-1) + 3 = 3

3 = 3

If the concentration of mercury in the water of a polluted lake is 0.300 μg (micrograms) per liter of water, what is the total m
Reika [66]

Answer: 151.305 kg

Step-by-step explanation:

0.300μg = 0.3x10⁻⁶ g/l

mass in kg?

Volume of lake = surface area * depth

surface area = 13mi²

depth = 49 ft

<u>Feet to miles</u>

49 ft → mi = 0.00928 mi

(1 mi = 5280 ft)

V = 13*0.00928 = 0.121 mi³

<u>cubic Miles to cubic meters</u>

1mi³ = 4168182000 m³

0.121 mi³ = 504350022 m³

<u>Cubic meters to liters</u>

1L = 1000 m³

Lake has 5.04350022x10¹¹ L

Concentration = 0.3x10⁻⁶ g/l

Lake has 151305 g of Hg = 151.305 kg of Hg

What does acute look like
horrorfan [7]
Any acute angle means that the angle is less than 90 degrees and it less than a right angle so it tends to look squished or pressed.

Investments increase exponentially by
Blizzard [7]

Using an exponential function, it is found that you would have $10,240 after 18 years.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

Considering the initial value of $2,500, and the growth rate of 60% every 6 years, the equation is given by:

A(t) = 2500(1.6)^\frac{t}{6}

Hence, after 18 years, the amount is given by:

A(18) = 2500(1.6)^\frac{18}{6} = 10240
