If a linear equation has the same variable term but different constant values on opposite sides of the equation, it has no solutions.

How do you tell if a system of equations has no solution algebraically?

If a linear equation has the same variable term but different constant values on opposite sides of the equation, it has no solutions.

What does a system look like if it has no solution?

If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

How long will it take for an investment to triple, if interest is compounded continuously at 8%?
maw [93]

Answer:

<em>It will take 14 years before the investment triples</em>

Step-by-step explanation:

<u>Continuous Compounding</u>

Is the mathematical limit that compound interest can reach if it was calculated and reinvested into an account's balance over a theoretically infinite number of periods.

The formula for continuous compounding is derived from the formula for the future value of a compound interest investment:

FV = PV\cdot e^{i.t}

Where:

FV = Future value of the investment

PV = Present value of the investment

i     = Interest rate

t     = Time

It's required to find the time for an investment to triple, that is, FV = 3 PV, knowing the interest rate is i=8%=0.08.

Substituting the known values:

3PV = PV\cdot e^{i.t}

Dividing by PV:

3 = e^{i.t}

Taking logarithms:

\ln 3=i.t

Solving for t:

\displaystyle t=\frac{\ln 3}{i}

\displaystyle t=\frac{\ln 3}{0.08}

t = 13.7 years

Rounding up:

It will take 14 years before the investment triples

Which describes the combined variation in the formula h=V/pie r2
Mice21 [21]

Answer:

The correct option is (c).

Step-by-step explanation:

The combined formula is given by :

h=\dfrac{V}{\pi r^2} ...(1)

h is height

V is volume

r is radius

It is clear from formula (1) that h varies directly with V and inverse;y with the square of r.

Hence, the correct option is (c).
