Answer:
(86 – h) + h = 86
Step-by-step explanation:
$70+$260= $330
34 lemonade + 52 hot dogs = 86 items = $330
With 34 lemonade + 52 hotdogs h= 52
(86 – h) + h = 86 = 86-52+52=86
D. $1086.60 1st month: 150 2nd month: 161.25 3rd month: 173.34 4th month: 186.34 5 month: 200.32 6 month: 215.34 then you just add them all up
Answer:Graph A
Step-by-step explanation: hope this you plz mark as brainest
Degrees because its a full circle unless your doing the opposite to both sides
Answer:
x = π/4 - 1/4 sin^(-1)(7/10) + (π n_1)/2 for n_1 element Z
or x = (π n_2)/2 + 1/4 sin^(-1)(7/10) for n_2 element Z
Step-by-step explanation:
Solve for x:
cos(6 x) sin(2 x) - cos(2 x) sin(6 x) = -0.7
-0.7 = -7/10:
cos(6 x) sin(2 x) - cos(2 x) sin(6 x) = -7/10
Reduce trigonometric functions:
-sin(4 x) = -7/10
Multiply both sides by -1:
sin(4 x) = 7/10
Take the inverse sine of both sides:
4 x = π - sin^(-1)(7/10) + 2 π n_1 for n_1 element Z
or 4 x = 2 π n_2 + sin^(-1)(7/10) for n_2 element Z
Divide both sides by 4:
x = π/4 - 1/4 sin^(-1)(7/10) + (π n_1)/2 for n_1 element Z
or 4 x = 2 π n_2 + sin^(-1)(7/10) for n_2 element Z
Divide both sides by 4:
Answer: x = π/4 - 1/4 sin^(-1)(7/10) + (π n_1)/2 for n_1 element Z
or x = (π n_2)/2 + 1/4 sin^(-1)(7/10) for n_2 element Z
