Find the area of the figure.
seraphim [82]

\huge \bf༆ Answer ༄

At first Divide the figure into two rectangles, I and Il

Area of figure l is ~

  • \sf24 \times (40 - 30)

  • \sf24 \times 10

  • \sf240 \:  \: ft {}^{2}

Area of figure ll is ~

  • \sf 18 \times 30

  • \sf540 \: ft{}^{2}

Area of whole figure = Area ( l + ll )

that is equal to ~

  • \sf240 + 540

  • \sf780 \:  \: ft{}^{2}

The first five terms of a sequence are
Elena L [17]

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
