56. What is the unit digit in the expansion of (89628)402?(1) 8(2) 6(3) 4(4) 2

Answer»

Given : (89628)⁴⁰²

To Find : unit Digit

(1) 8

(2) 6

(3) 4

(4) 2

Solution:

(89628)⁴⁰²

= (89628)⁴⁰⁰⁺²

= (89628)⁴⁰⁰.(89628)²

= ((89628)⁴)¹⁰⁰.(89628)²

8⁴ ENDS with 6

6¹⁰⁰ end with 6

8² ends with 4

(6)(4) = 24

Hence (89628)⁴⁰² ends with 4

Unit digit of (89628)⁴⁰² is 4

Answer» ANSWER: ( 2p+5 ) ( p - 7 ) Step-by-step explanation: 2p²- 9p - 35(factorise) Answer : Product = 2p^2 X ( -35 ) SUM = 9p So, 2p^2- 14p + 5p - 35 = 2p ( p - 7 ) + 5 ( p - 7 ) = ( 2p+5 ) ( p - 7 )

29.

2p²- 9p - 35(factorise)

Answer»

ANSWER:

( 2p+5 ) ( p - 7 )

Step-by-step explanation:

2p²- 9p - 35(factorise)

Answer :

Product = 2p^2 X ( -35 )

SUM = 9p

So,

2p^2- 14p + 5p - 35

= 2p ( p - 7 ) + 5 ( p - 7 )

= ( 2p+5 ) ( p - 7 )

Answer» (C) x + y = 23 Let the length of the rectangle be ‘x’ and that of breadth be ‘y’. PERIMETER of rectangle = 2[(x – 5) + (y – 5)] ∴ 26 = 2(x + y – 10) ∴ x + y – 10 = 13 ∴ x + y = 23

36.

When 5 is subtracted from length and breath of the rectangle, the perimeter becomes 26. what is the mathematical form of the statement? *x-y=8x+y=8x+y=232x+y=21

Answer»

(C) x + y = 23

Let the length of the rectangle be ‘x’ and that of breadth be ‘y’.

PERIMETER of rectangle = 2[(x – 5) + (y – 5)]

∴ 26 = 2(x + y – 10)

∴ x + y – 10 = 13

∴ x + y = 23

Answer» LET AP 60 m be the height of the window above the ground.(AP = QC) CD = h m be the height of the HOUSE on the opposite side of the Street GIVEN: ∠QPD = 60°(angle of elevation of the top of D of house CD) ∠QPC = 45° (angle of depression of the foot C of the house CD) QD = CD - CQ QD = CD - AP [CQ = AP] QD = (h - 60) m In ∆PQC, TAN 45° = QC/PQ = P/B 1 = 60/PQ PQ = 60 m In ∆PQD , tan 60° = QD/PQ = P/B √3 = (h-60)/60 60√3 = (h-60) 60√3 +60 = h 60(√3+1) = h Hence, the height of the opposite house is 60(√3+1) m.

From a window 20m high above the ground in a street, the angle of elevationand depression of the top and the foot of another house opposite side of thestreet are 60° and 45° respectively. Find the height of opposite house.( Take √ = 1.73)

Answer»

LET AP 60 m be the height of the window above the ground.(AP = QC)

CD = h m be the height of the HOUSE on the opposite side of the Street

GIVEN:

∠QPD = 60°(angle of elevation of the top of D of house CD)

∠QPC = 45° (angle of depression of the foot C of the house CD)

QD = CD - CQ

QD = CD - AP [CQ = AP]

QD = (h - 60) m

In ∆PQC,

TAN 45° = QC/PQ = P/B

1 = 60/PQ

PQ = 60 m

In ∆PQD ,

tan 60° = QD/PQ = P/B

√3 = (h-60)/60

60√3 = (h-60)

60√3 +60 = h

60(√3+1) = h

Hence, the height of the opposite house is 60(√3+1) m.
