TRIGONOMETRY
Approximate the logarithm using the properties of logarithms, given the values $\log _{b} 2 \approx 0.3562, \log _{b} 3 \approx 0.5646,$ and $\log _{b} 5 \approx 0.8271$. $\log _{b} \sqrt{5}$
TRIGONOMETRY
Find the probability for the experiment of drawing two marbles at random (without replacement) from a bag containing one green, two yellow, and three red marbles. (Hint: Use combinations to find the numbers of outcomes for the given event and sample space.) Neither marble is yellow.
TRIGONOMETRY
The center of a Ferris wheel lies at the pole of the polar coordinate system, where the distances are in feet. Passengers enter a car at (30, -π/2). It takes 45 seconds for the wheel to complete one clockwise revolution. Write a polar equation that models the possible positions of a passenger car.
TRIGONOMETRY
A florist is creating 10 centerpieces for the tables at a wedding reception. Roses cost $$ \$ 2.50 $$ each. Lilies cost $4 each, and irises cost$2 each. The customer has a budget of $300 for the centerpieces and wants each centerpiece to contain 12 flowers, with twice as many roses as the number of irises and lilies combined. Solve your linear system using an inverse matrix. Find the number of flowers of each type that the florist can use to create the 10 centerpieces.
