Spencer would like to attend the University of El Dorado, which costs $24,000 per year. He plans to save money each month for the next 4 years in order to reach his goal. His grandparents will contribute 25% for his first
year's tuition. If Spencer also receives a local scholarship for $3,000, how much money will he need to save
each month to cover his first year of tuition?

Some boys and girls were asked if they had a pet. one third of the group were boys. there were 20 boys. 20% of the girls had a pet. boys with a pet : girls with a pet = 1 : 5 i need to know how many girls there are.

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
