There are 2 ways to do this....
(1) 20(1.15) = 23
(2) 20 + 0.15(20) = 20 + 3 = 23
Answer:
325
Step-by-step explanation:
Notice you are adding 7 everytime.
So the sequence would be:
a(n) = 10 + 7n
n=0 gives a(0)=10, which is the first term.
so the 46th term has n=45.
a(45)=10 + 7*45=325
Answer:
1+sq root 3/2 or 1+1.732/2
Step-by-step explanation:
sin 30°=1/2
cos 30°= under sq. root 3/2
so
sq root 3= 1.732
Solving the triangle requires solving all of the dimensions involve in the polygon given. We are given an angle, and two of the sides of the triangle. We can solve the third side by using the law of cosines.
b² = a²+c²-2accos(B)
b² = 38² + 18² - 2(38)(18)cos(36)
b = 25.7
We use the law of sines to solve for the angles.
a/sinA = b/sinB
38/sinA = 25.7/sin36
A = 60.4°
C = 180 - 36 - 60.4 = 83.6°
Answer:
-2x+6y
Step-by-step explanation:
2x-4x= -2x
3y+3y= 6y
x= -2x
y= 6y
The answer would be -2x+6y
I really do hope I answer your question!
