(1 point) The length of an insect (L, in mm) is a function of the temperature during development (T , measured in ∘C according to L(T)=8+T10 ) . The volume of the insect (V , in cubic mm) is a function of the length according to V(L)=7L3 . The mass (M in milligrams) depends on volume according to M(V)=1.1V . Find mass as a function of temperature. M(T)= How much would an insect weigh that developed at 22∘C?

2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a).F = ma(a) Solve this equation for a. Hint: Use what you learned about related equations (like fact families) to help you rearrange the expression F = ma to solve for a.(b) Let the force be units and the mass be m = 5 units. What is the acceleration, a? Show your work.(c) Let the force be F = 25 units and the acceleration be a = 2.5 units. What is the mass, m? Show your work.

A woman is standing at the edge of a slow-moving river which is one mile wide, and she wishes to return to her campground on the opposite side of the river. Assume that the woman can walk at 5 miles per hour and swim at 3 miles per hour, and that she will first swim to cross the river and then walk the remaining distance to the campground, which is 10 miles downstream from the point directly across the river from the woman's starting point. What route will take the least amount of time?

The symbol ∪ represents the union of events. The union of two events A and B results in an event that contains all the sample points of event A or event B or both events. Therefore, A ∪ B is a new event that lists the sample points of event A or event B or both events. Recall the set notation used for an event with k sample points. event = {sample point 1, sample point 2, , sample point k} Event A is made up of the sample points E1, E4, and E6 and event B is made up of the sample points E2, E4, and E7. Thus, the union of events A and B will have what sample points that are contained in either A or B?
