2x^4 + 3x^3 - 5x + 6 ÷ x^2 + 3x - 2

1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m

Which statement is true:
a) Jill will make less money if they each work 4 hours.
b) Jill's hourly rate is $3 more than kara's.
c) Kara charges $14 and hour for babysitting two children.
d) Kara's fee for the second child is $5.
Answer:
(D)Kara's fee for the second child is $5.
Step-by-step explanation:

From the table above,
Jill Charges an hourly rate of $11
Kara charges an hourly rate of $9 and an additional $5 charge for more than one child. Therefore, the statement that is true is Option D.
Kara's fee for the second child is $5.
All other options are incorrect.
<u>Check</u>
Option A: In four hours, Jill will make $44 while Kara will make $41
Option B: Jill's hourly rate is $2 more than Kara's, NOT $3.
Option C: Kara charges $9 an hour, NOT $14.

Answer:
Step-by-step explanation:
sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
cos² x + sin² x = 1
