Step-by-step explanation:
Answer:
(a) 7 + 3( n - 1 )
(b) 1006
Step-by-step explanation:
ARITHMETIC SEQUENCE.
The number of term of an Arithmetic progression has the formular :
nth term = a + ( n - 1 ) d
a = 7
d = 10 - 7 = 3
nth term = 7 + ( n - 1 ) 3
= 7 + 3n - 3
= 7 + 3( n - 1 )
Therefore,
the nth term of the sequence
= 7 + 3( n - 1 )
(b) For the 1000th term
= 7 + 3 ( 1000-1 )
= 7 + ( 999 )
7 + 999 = 1006
Therefore,
the 1000th term = 1006
Answer:
178 sq in
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, we know the formula for finding the area of a rectangle is B*H, and the formula for finding the area of a circle is πr^2
Let's find the area of a rectangle first:
25*6=150 sq in
Now the semicircles {which combined into one whole circle because they're two halves}:
The diameter is 6 inches, so the radius is 3 inches.
π(3)^2=9π
9*π=28.27 which can be rounded down to 28 sq in.
To fin the area of both, we would add them together:
150+28=178 square inches
