Answer:

Step-by-step explanation:

p=sec0+tan0

=1/cos0 + sin0/cos0

=(1+sin0)/cos0

square both sides

(1+sin)^2 /cos^2 = p^2

(1+sin)^2/(1 - sin^2 ) = p^2

(1+sin)^2/((1-sin)(1+sin)) = p^2

(1+sin)/(1-sin)=p^2

1+sin=p^2-p^sin

sin+p^2sin=p^2-1

sin(1+p^2)=(p^2-1)

sin=(1-p^2)/(1+p^2)

cosec=1/sin

=(1+p^2)/(1-p^2)

The average monthly rent for a? 1000-sq-ft apartment in a major metropolitan area from 1998 through 2005 can be approximated by

Lunna [17]

Answer:

t = 1.107

Step-by-step explanation:

Finding the solution using derivatives involves finding the lower zero of the quadratic that is the second derivative of the given function. That second derivative will be ...

f''(t) = 12(1.6714)t^2 -6(22.45)t +2(62.27)

= 20.0568t^2 -134.7t +124.54

= 20.0568(t -3.35796)² -101.619 . . . . rewrite to vertex form

Then f''(t) = 0 when ...

t ≈ 3.35796 -√(101.619/20.0568) ≈ 1.10706

The solution is perhaps more easily found using a graphing calculator to find the peak of the first derivative. (See attached.) It tells us ...

t ≈ 1.107

1.1 years after the beginning of 1998 is about 1.2 months into 1999.

Rents were increasing most rapidly in early February of 1999.

Answer:

$y = 1500(0.024)^t$

Step-by-step explanation:

Given

$a = 1500km$ -- initial area

$b = 2.4\%$ -- rate

$t = time$ --- (years)

Required

Represent as an exponential function

An exponential function has the form:

$y = ab^t$

Where

$a = initial\ value$

$b = rate$ and $b \ne 1$

$t= time$

Substitute values for a and b, we have:

$y = 1500 * (2.4\%)^t$

Convert percentage to decimal

$y = 1500 * (0.024)^t$

$y = 1500(0.024)^t$

Hence, the exponential function that represents the scenario is: $y = 1500(0.024)^t$
