Linear Ordinary Differential Equation
Answer:
6,000 & 19,200
Answer:
x=10
Step-by-step explanation:
9x-3=87
you add 3 to both sides
9x-3(+3)=87(+3)
which equals
9x=90
90/9= 10
answer:
x =10
I hope this helped!
Answer:
x=10
Step-by-step explanation:
9x-3=87
add 3 to both sides
9x=90
divide by 9 on both sides
x=10
Answer:The fourth option

Answer:
The Fourth Answer
Step-by-step explanation:
Answer:
Labor = $14.65
Step-by-step explanation:
25.15-22.15= 3 3/2 = 1.5
1qt = $1.5
1.5 x 5 = $7.5
22.15 - 7.5 = $14.65
1.5 x 7 = 10.5
25.15 - 10.5 = $14.65
Labor = $14.65
sin 2x sin x + cos x= 0
Use the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Now rewrite
sin(2x) sin(x) + cos(x) = 0
as
2 sin²(x) cos(x) + cos(x) = 0
Factor out cos(x) :
cos(x) (2 sin²(x) + 1) = 0
Consider the two cases,
cos(x) = 0 OR 2 sin²(x) + 1 = 0
Solve for cos(x) and sin²(x) :
cos(x) = 0 OR sin²(x) = -1/2
Squaring a real number always gives a non-negative number, so the second case doesn't offer any real solutions. We're left with
cos(x) = 0
Cosine is zero for odd multiples of π/2, so we have
x = (2n + 1) π/2
where n is any integer.
