If
is the variable of the horizontal axis, then you can solve for
to get the equation of the line in slope-intercept form in the
plane:
i.e. a line with slope
through the origin, which means it is contained in the first and third quadrants. Since the terminal side of
has a negative sine, the angle must lie in the third quadrant.
Because the slope of the line is
, you can choose any length along the line to make up the hypotenuse of a right triangle with reference angle
. Any such right triangle will have
, regardless of whether the angle is the first or third quadrant. But since
is known to lie in the third quadrant, and so
and
are both negative, you have
I agree. From the calculation, the total <em>amount spent </em><em>is </em><em>less than</em><em> (<)the amount in his pocket</em>, this means that <em>Rashaj can buy 5 boxes of candy. </em>
Inequalities are expressions that are not always equal to each other. The inequality signs are <, > ≤ and ≥
Given the following
Amount Rashaj has in his wallet = $37.25
Amount spent
A movie ticket = $7.25
5 boxes of candy at $3.75 per box = 5($3.75) = $18.75
Taking the sum of the total amount spent
Amount spent = $7.25 + $18.75
Amount spent = $26
Since the total <em>amount spent </em><em>is </em><em>less than</em><em> (<)the amount in his pocket</em>, this means that <em>Rashaj can buy 5 boxes of candy. </em>

The answer for this question is D because you have 2 full squares and then one half of square so 2 1/2.
Use the given values in the compound interest formula to solve for time, n.
A is the final amount of money, $2800
P is the initial or starting amount $1900
i is the interest rate as a decimal 0.025
n is time in years since it annual.
2800 = 1900(1 + 0.025)^n
2800 = 1900(1.025)^n
2800/1900 = (1.025)^n
28/19 = (1.025)^n
take the natural log of both sides to solve for exponent.
ln(28/19) = ln(1.025^n)
power rule of logarithmic moves exponent
ln(28/19) = n*ln(1.025)
ln(28/19) / ln(1.025) = n

15.7 years = n
