Answer:
B or C (they're the same?)
Step-by-step explanation:
y - 25= 1981
y = 1981 + 25
y = 2006
Here,
Third term (a) = 5
Seventh term (b) = 9
17th number = ?
Now,
T3 = a + 2d
5 = a + 2d
d = (5 - a)/2 ------ 1.
T7 = a + 6d
9 = a + 6d
d = (9 - a)/6 ------- 2.
Combining eq (1) and (2)
or, (5 - a)/2 = (9 - a)/6
or, 6 (5 - a) = 2 (9 -a)
or, 30 - 6a = 18 - 2a
or, 12 = 4a
◆ a = 3
putting the value of a in eq (1)
or, d = (5 - 3)/2
or, d = 2/2
◆ d = 1
Then,
T17 = a + 16d
= 3 + 16
= 19
◆ T17 = 19
I hope you understand...
This is Right answer...

Answer:
The scale factor is ( 1/3)
The dilation is reduction
Step-by-step explanation:

I hope that is useful for you :)
The area equation for a rectangle is length times width. And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.
So, you have to add the area of the rectangle and semi-circle together.
Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2
Add those together to get 307.17cm^2 or choice C.
Answer:
B) 40.192
Step-by-step explanation:
The equation is 2 x
x r 2 x 3.14 x 6.4 . multiply them and you get 40.192
