Answer:
Sue
Step-by-step explanation:
Sue will charge for the first hour and 9 additional hours, for a total of ...
$15 +9·10 = $105
Vic's charge for 10 hours will use the formula for x≥8, so will be ....
9.5(10) = 95 . . . dollars
For 10 hours' babysitting, Sue will charge more.
We know that
if <span>180º≤A≤270º
</span>then
A belongs to the III quadrant and tan A is positive
we have
5tan²A = 2tanA + 6-------> 5tan²A - 2tanA - 6=0
let
x=tan A
5x²-2x-6=0
using a graph tool----> to resolve the second order equation
see the attached figure
x=-0.91
x=1.314
remember that tan A is positive
the solution is
x=1.314
tan A=1.314
A=arc tan (1.314)--------> A=52.73°-----> A=52.7°
180º≤A≤270º
then
A=180+52.7-----> A=232.7°
the answer isA=232.7°
