(1- cos2x) dx
= x - 1/2 sin2x + c
= x - 1/2 ( 2*sinx cosx) +c
= x - ((sinx) (cosx)) +c
Answer:
Part 8) B.F=0.5 units
Part 9) A.B=2 units
Step-by-step explanation:
we have
The diameter of circle F is 5 units
so
The radius of circle F is r.f=5/2=2.5 units
The diameter of circle G is 6 units
so
The radius of circle G is r.g=6/2=3 units
Part 8) Find B.F
we know that
B.F=G.B-F.G
we have
G.B=rg=3 units
FG=rf=2.5 units
substitute the values
B.F=3-2.5=0.5 units
Part 9) Find A.B
we know that
A.B=A.F-B.F
we have
A.F=r.f=2.5 units
B.F=0.5 units
substitute the values
A.B=2.5-0.5=2 units
Answer:
11
Step-by-step explanation:
17 ft=17x12=204 inches
204/18=11.333...
So you can cut 11 logs
∠2 and ∠4 are vertical opposite angles and they are congruent.
<h3>How to prove vertical angles?</h3>
Vertically opposite angles are congruent.
Therefore, let proof ∠2 and ∠4 are vertical angles
Hence,
m∠2 + m∠3 = 180
∠2 and ∠3 are linear pair.
m∠3 + m∠4 = 180
∠3 and ∠4 are linear pair.
∠2 and ∠4 are vertical angles
m∠2 + m∠3 = m∠3 + m∠4

#SPJ1
Answer:
C.) 21
Step-by-step explanation:
d = 22.5n + 27.5
Where d is the total amount of money earned and n is the number of items sold
Substitute:
500 = 22.5n + 27.5
We can substitute 500 for d because 500 is the total amount of money Kathryn wants to earn
Solve:
500 = 22.5n + 27.5
Subtract 27.5 on both sides:
500 = 22.5n + 27.5
-27.5 -27.5
472.5 = 22.5n
Divide by 22.5 on both sides:
472.5 = 22.5n
/22.5 /22.5
21 = n
Therefore, Kathryn must sell 21 items to make $500.
