From 1990 to 2010, the numbers (in millions) of female F and male M
employees from the ages of 16 to 19 in the United States can be modeled by F(t)=−0.007t2+0.10t+3.7
and M(t)=0.0001t3−0.009t2+0.11t+3.7
, where t
is the number of years since 1990.
a. Find (F+M)(t)
.

(F+M)(t)=

Question 2

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
