A certain painting was purchased for $15,000. Its value is predicted to decay exponentially decreasing by 15% each year. Which equation can be used to predict t, the number of years it would take for the painting to have a value of $10,000?
A 10,000(0.15)' = 15,000
B. 15,000(0.15)' = 10,000
O G. 15,000(0.85)' = 10,000
D. 10,000(0.85)' = 15,000

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65

What is the area of a triangle with vertices at (-3 3) (-3,2) and (1,2)?

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
