You are a test engineer. An experimental aircraft you test flies 1.3- , 1.2- , and 1.5- hour flights during day 1 of the test. what is the total flight time for the day in hours?

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

step-by-step explanation: 2

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
