Find the equation of a line that runs through

MAVERICK [17]

Answer:

The equation of a line that runs through (-6,2) and is parallel to a line with a slope of (-1/4) is x + 4y - 2 = 0

Step-by-step explanation:

Slope of the parallel equation is m 1 = (-1/4)

<em>If the two liner are parallel the, slope of both lines are equal.</em>

⇒The slope of the equation of line = m2 = m1 = -(1/4)

The point (x0, y0) = (-6,2)

Now, by THE POINT SLOPE FORMULA: The equation of a line is given as

( y - y0) = m (x -x0)

Now, here the equation of line is given as:

$y - 2 = (\frac{-1}{4}) (x - (-6)) \implies 4(y-2) = -1(x + 6)$

or, 4y - 8 + x + 6 = 0

or, x + 4y - 2 = 0

Hence, the required line equation is x + 4y - 2 = 0

The population of a city can be modeled by P(t) 3810(1.0005)7t , where P(t) is the population after t years. Which function is a

swat32

Answer:

$P(t) = 3810(1.0035)^{t}$

Step-by-step explanation:

Given:

$P(t) = 3810(1.0005)^{7t}$ -----(1)

Simplifying $(1.0005)^{7t}$

From Law of indices, $x^{mn} = (x^{m})^{n}$

$(1.0005)^{7t}$ = $(1.0005^{7})^{t}$

When 1.0005 is raised to the 7th power, it is approximately 1.0035.

Substituting $(1.0005)^{7t} = (1.0035)^{t}$ into equation(1)

$P(t) = 3810(1.0035)^{t}$

You are considering buying a 30-year U.S. Treasury bond but are nervous about the effect on bond price if the yield to maturity

Savatey [412]

Answer:

The corresponding change in bond price = 17.1%

Step-by-step explanation:

In this question, we are interested in calculating the percentage change in the bond price using the approximation method based on bond duration;

Mathematically;

% change in bond price = Duration * Change in yield

From the question;

Duration = 19 years

Change in yield = 0.9%

Thus;

% change in bond price = 19 * 0.9% = 17.1%
