Answer:
Step-by-step explanation:
A
AC = √(40²-12²) = √(1600-144) = √1456 = 4√91
tanA = 12/4√91 = 3/√91 = 3√91/91
option а.
None of the choices are equivalent
64/4 is 16
a is 4
b is 4
c is 2
d is 1
23. The answer is D. If you multiply 0.8 by 5 you get 4 meters which means it would take 5 minutes. Multiplying it by 5 will give you a whole number therefore easier to find on the graph.
24. The answer is G. The square root of 5 is 2.23 and the square root of 2 is 1.4
