Rus_ich [418]

$\ell_1$ and $\ell_2$ are parallel to one another with slope 1. Any line with slope -1 is perpendicular to both of these lines, the simplest being $y=-x$ .

This perpendicular line intersects $\ell_1$ and $\ell_2$ at the points (5/2, -5/2) and (1/2, -1/2), respectively.

The distance between $\ell_1$ and $\ell_2$ is the same as the distance between these two intersections:

$\sqrt{\left(\dfrac52-\dfrac12\right)^2+\left(-\dfrac52+\dfrac12\right)^2}=2\sqrt2\approx\boxed{2.8}$

BaLLatris [955]

Answer:

$i = 1,8087 %$

$r = 1.018$

Step-by-step explanation:

For an effective annual rate j you have that the monthly interest rate can be related to it as:

$(1+i)^{12} = 1+j$

Solving for i:

$i=\sqrt[12]{1+j} -1$

replacing j = 24% => i = 1,8087 %

So growth rate r would be:

$r = 1 + i = 1.018$

KATRIN_1 [288]

Answer:

Step 1: Finding r using the formula ln 2/h

$1.\ r=\frac{ln\ 2}{h}\\ r=\frac{ln\ 2}{140}\\r=0.00495$

Step 2: Substitute the values in given formula

$2.\ m_t=m_0e^{-rt}\\200=300e^{-0.00495t}$

Step 3: Divide both sides by 300

$\frac{2}{3} =e^{-0.00495t}$

Step 4: Take the natural logarithm on both sides

$ln\ \frac{2}{3} =ln\ e^{0.00495t}$

Step 5: Simplify

$-0.405 = -0.00495t$

Step 6: Divide both sides by 0.00495

$\frac{-0.405}{-0.00495} =t$

Step 7: Simplify

$t=81.8\ days$
