A carpet costs $15 per square metre. The total delivery charge is $21. Peter buys n square metres of carpet. Select the expression which represents the total cost in $.

Answer»

GIVEN:

The cost carpet per square meter = 15$

The total DELIVERY CHARGE = 21$

To find:

The expression which represents total cost in $

Calculation:

Peter buys n square meters of carpet. So the costvof n square meters of carpet will be

Cost of n square meters of carpet = (n×15)$

Total cost = Cost of the carpet for n square meters + Delivery charges

= (15N + 21)$

The expression which represents the total cost in $ is 15n+21

Answer»

Answer:

$Let \: the \: original \: l\:<klux>LENGTH</klux> \: of \: rectangle$

be.L,breadth be B and area be A

A=L×B=LB

New length,L1=L+100%L

=L+100L100

=L+L=2L

New breadth,B1=B+100%B

=B+100B100

=B+B=BL

New Area,A1=L1×B1=2L×2B=4LB

Change in area=A1−A

=4LB−LB=3LB

Increase in area in percent

=Change in area Original area×100

=A1−AA×100

=3LBLB×100

=300%

Answer» Answer: 8 Step-by-step explanation: Let each roots is 'a'. In equations written in FORM of ax² + BX + c = 0, -b/a is sum of roots ; c/a is product of roots. Here, as both roots are equal: = > sum = -(8/2) = > a + a = - 4 = > 2a = - 4 → a = - 2 WHEREAS, = > product = k/2 = > a*a = k/2 = > (-2)(-2) = k/2 = > 4 = k/2 = > 8 = k

32.

If the roots of the quadratic equation 2x2+8x+k=0 are equal them find the value of k.

Answer»

Answer:

8

Step-by-step explanation:

Let each roots is 'a'.

In equations written in FORM of ax² + BX + c = 0,

-b/a is sum of roots ; c/a is product of roots.

Here, as both roots are equal:

= > sum = -(8/2)

= > a + a = - 4

= > 2a = - 4 → a = - 2

WHEREAS,

= > product = k/2

= > a*a = k/2

= > (-2)(-2) = k/2

= > 4 = k/2

= > 8 = k

Two vectors have magnitudes 3 unit and 4 unit respectively. What should be the angle betweenthem if the magnitude of the resultant is (a) 1 unit, (b) 5 unit and (c) 7 unit.

Answer»

Solution:-

$: \implies \sf \: magnitude \: of \: \vec{a} \: |a| = 3unit \:$

$: \implies \sf \: magnitude \: of \: \vec{<klux>B</klux>} \: |b| = 4unit \:$

$\sf \: \to formula$

$\boxed{\sf \: R = \sqrt{ {A }^{2} + {B}^{2} + 2A B \cos \theta } }$

Case :- 1 R = 1 unit

A = 3 unit and B = 4 unit

Using this

$\sf \: R = \sqrt{ {A }^{2} + {B}^{2} + 2A B \cos \theta }$

$\sf \: 1 = \sqrt{ {3}^{2} + {4}^{2} + 2 \times 3 \times 4 \cos \theta }$

$\sf \: 1 = {9}^{} + {16}^{} + 24 \cos \theta$

$\sf \: 1 = {25}^{} {}^{} + 24 \cos \theta$

$\sf \: 1 - 25= {}^{} {}^{} 24 \cos \theta$

$\sf \: - 24= {}^{} {}^{} 24 \cos \theta$

$\sf \cos \theta = - 1$

$\theta \: = 180 \degree$

Case :- 2 R = 5 unit

Case :- 2 R = 5 unit A = 3 unit and B = 4 unit

Case :- 2 R = 5 unit A = 3 unit and B = 4 unit Using this

$\sf \: R = \sqrt{ {A }^{2} + {B}^{2} + 2A B \cos \theta }$

$\sf \: 5 = \sqrt{ {3}^{2} + {4}^{2} + 2 \times 3 \times 4 \cos \theta }$

$\sf \: 25= {9}^{} + {16}^{} + 24 \cos \theta$

$\sf\: 25 = 25 + 24 \cos \theta$

$\sf0 = 24 \cos \theta$

$\cos \theta = 0$

$\rm \: \theta = 90 \degree$

Case :- 3 R = 7 unit

unit A = 3 unit and B = 4 unit

unit A = 3 unit and B = 4 unit Using this

$\sf \: R = \sqrt{ {A }^{2} + {B}^{2} + 2A B \cos \theta }$

$\sf \: 7 = \sqrt{ {3}^{2} + {4}^{2} + 2 \times 3 \times 4 \cos \theta }$

$\sf \: 49= {9}^{} + {16}^{} + 24 \cos \theta$

$\sf \: 49 = 25 + 24 \cos \theta$

$\sf \: 24 = 24 \cos \theta$

$\cos\theta = 1$

$\theta = 0 \degree$

किसी चतुर्भुज के चारों कोणों पी में है जिनका सार्व अंतर 10 डिग्री है कोनार्का मान ज्ञात कीजिए

Answer»

Step-by-step EXPLANATION:

दिया गया है:किसी चतुर्भुज के चारों कोणों A.P. में है जिनका सार्व अंतर 10 डिग्री है|

ज्ञात करना है: कोणों का मान ज्ञात कीजिए|

हल: हम जानते हैं कि चतुर्भुज के चारों अंतः कोणों का योग 360 डिग्री होता है|

और प्रश्न के अनुसार चतुर्भुज के चारों कोण समानांतर श्रेणी में है , तो एक कोण a होगा ,

दूसरा कोण= a+d

तीसरे का मान =a+2d

चौथे का मान=a+3d होगा|

और यहां पर सार्व अंतर d= 10° दे रखा है |

अब इन चारों कोणों को जोड़कर हम कोणों का मान निकाल लेंगे

$a + a + d + a + 2d + a + 3d = 360° \\ \\ 4a + 6d = 360 \\ \\ 4a + 6 \times 10°= 360° \\ \\ 4a = 360° - 60° \\ \\ 4a = 300° \\ \\ a = \frac{300°}{4} \\ \\ a = 75° \\ \\$

एक कोण 75° का होगा ,

दूसरा कोण= a+d= 75°+10°=85°

तीसरे का मान =a+2d=75°+20°=95°

चौथे का मान=a+3d =75°+30°=105° होगा|

आशा है यह उत्तर आपकी मदद करेगा |
