1.

Find the zeroes of the polynomials p(x

Answer»

Step-by-step EXPLANATION:

$\: \: \: \: 2 {x}^{2} + 5x - 12 = <klux>0</klux> \\ = > 2 {x}^{2} + 8x - 3x - 12 = 0 \\ = > 2x(x + <klux>4</klux>) - 3(x + 4) = 0 \\ = > (x + 4)(2x - 3) = 0$

x+4=0. |. 2x-3. =0

=>. x=-4. |. => 2x=3

|. =>. x=3/2

x=. -4 and 3/2.

Answer» The risk of short-term mortality following elective AAA repair is dependent on both patient and operative characteristics. The risk of in-hospital mortality following a SURGICAL procedure is COMMONLY estimated USING a risk prediction model. A risk prediction model is a mathematical FORMULA that utilises risk factor information to estimate the probability of a patient developing an outcome. Several risk prediction models have been developed and validated for predicting outcomes following AAA repair. A systematic review published in 2008 found that, out of the available risk PREDICATION models, the Glasgow Aneurysm Score (GAS) was the most useful model but none was entirely satisfactory.52,53

27.	The age of sonal and manoj are in the ratio 7 is to 5 10 years hence the ratio of their ages will be 39 is 27 find their present age
Answer» CORRECT QUESTION The age of sonal and manoj are in the ratio 7 : 5 10 years hence the ratio of their ages will be 9:7 TO FIND Find their present ages SOLUTION ✹ LET the present age of Sonal be 7x and Manoj be 5x **According to the given condition ✹ After 10 years Sonal's age = 7x + 10 Manoj's age = 5x + 10 ➨ 7x + 10/5x + 10 = 9/7 ➨ 7x + 10/5x + 10 = 9/7 ➨ 7(7x + 10) = 9(5x + 10) ➨ 49x + 70 = 45x + 90 ➨ 49x - 45x = 90 - 70 ➨ 4X = 20 ➨ x = 20/4 = 5 Hence, Present age of Sonal** = 7x = 75 = 35year Present age of Manoj= 5x = 55=25 year

27.

The age of sonal and manoj are in the ratio 7 is to 5 10 years hence the ratio of their ages will be 39 is 27 find their present age

Answer»

CORRECT QUESTION

The age of sonal and manoj are in the ratio 7 : 5 10 years hence the ratio of their ages will be 9:7

TO FIND

Find their present ages

SOLUTION

✹ LET the present age of Sonal be 7x and Manoj be 5x

**According to the given condition**

✹ After 10 years

Sonal's age = 7x + 10
Manoj's age = 5x + 10

➨ 7x + 10/5x + 10 = 9/7

➨ 7(7x + 10) = 9(5x + 10)

➨ 49x + 70 = 45x + 90

➨ 49x - 45x = 90 - 70

➨ 4X = 20

➨ x = 20/4 = 5

Hence,

Present age of Sonal = 7x = 7*5 = 35year

Present age of Manoj= 5x = 5*5=25 year

Answer» $\red{\boxed{\boxed{ANSWER:-}}}$ समानांतर चतुर्भुज कैसे पहचानें: समानांतर चतुर्भुज एक चार भुजा वाली बंद आकृति होती है, जिनमें सम्मुख भुजाएं समानांतर तथा समान होती हैं। समानांतर चतुर्भुज में इनका समावेश होता है: वर्ग: चार भुजा; सभी समान लम्बाई की; चार कोण; सभी 90 अंश के (समकोण)। आयत: चार भुजा; सम्मुख भुजाएँ समान लम्बाई की; चार कोण, सभी 90 अंश। समचतुर्भुज: चार भुजा; सम्मुख भुजाएँ समान लम्बाई की; चार कोण , सम्मुख कोण समान परन्तु कोई कोण समकोण नहीं। 2 आयत का क्षेत्रफल ज्ञात करने के लिए आधार और ऊंचाई का गुणन कीजिये: एक आयत का क्षेत्रफल ज्ञात करने के लिए आपको दो माप चाहिए: चौड़ाई या आधार (चतुर्भुज की लम्बी भुजा) तथा लम्बाई या ऊंचाई (चतुर्भुज की छोटी भुजा)। क्षेत्रफल प्राप्त करने के लिए इन दोनों भुजाओं का गुणा कीजिये। दुसरे शब्दों में: क्षेत्रफल(A) = आधार(b) × ऊंचाई(H), या A = b × h संक्षिप्त में। उदाहारण: यदि एक आयत के आधार की लम्बाई 10 सेमी है और उसकी ऊंचाई 5 सेमी है, तो आयत का क्षेत्रफल 10 × 5 (b × h) = 50 वर्ग सेमी. ध्यान रखें कि किसी आकृति का क्षेत्रफल प्राप्त करने पर आप वर्ग इकाई (वर्ग सेमी, वर्ग मीटर , वर्ग फीट, इत्यादि) का उपयोग करेंगे। 3 वर्ग का क्षेत्रफल ज्ञात करते समय उसकी एक भुजा को उसी भुजा से गुणा कीजिये: वर्ग मूल रूप से एक विशेष आयत होता है, इसलिए आप वर्ग का क्षेत्रफल प्राप्त करने के लिए वही सूत्र उपयोग करते हैं। चूँकि वर्ग की सभी भुजाओं की लम्बाई समान होती है, आप सुगमता से एक भुजा को उसी भुजा से गुणन कर के क्षेत्रफल प्राप्त कर सकते हैं। यह वर्ग के आधार को उसकी ऊंचाई से गुणा करने के समान ही है, क्योंकि वर्ग में ऊंचाई और आधार की लम्बाई हमेशा समान ही होती है:[१] क्षेत्रफल(A) = भुजा(s) × भुजा(s) या A = s2 उदाहारण : यदि किसी वर्ग की एक भुजा की लम्बाई 4 फीट है, (t = 4), तो इस वर्ग का क्षेत्रफल t2, या 4 x 4 = 16 वर्ग फीट होगा

• एक समांतर चतुर्भुज का क्षेत्रफल ज्ञात कीजिए जिसकी दो आसन्न भुजाएँ क्रमश: 51 सेमी और 37 सेमी हों तथा एकविकर्ण 20 सेमी हो।

Answer»

$\red{\boxed{\boxed{ANSWER:-}}}$

समानांतर चतुर्भुज कैसे पहचानें: समानांतर चतुर्भुज एक चार भुजा वाली बंद आकृति होती है, जिनमें सम्मुख भुजाएं समानांतर तथा समान होती हैं। समानांतर चतुर्भुज में इनका समावेश होता है:

वर्ग: चार भुजा; सभी समान लम्बाई की; चार कोण; सभी 90 अंश के (समकोण)।

आयत: चार भुजा; सम्मुख भुजाएँ समान लम्बाई की; चार कोण, सभी 90 अंश।

समचतुर्भुज: चार भुजा; सम्मुख भुजाएँ समान लम्बाई की; चार कोण , सम्मुख कोण समान परन्तु कोई कोण समकोण नहीं।

2

आयत का क्षेत्रफल ज्ञात करने के लिए आधार और ऊंचाई का गुणन कीजिये: एक आयत का क्षेत्रफल ज्ञात करने के लिए आपको दो माप चाहिए: चौड़ाई या आधार (चतुर्भुज की लम्बी भुजा) तथा लम्बाई या ऊंचाई (चतुर्भुज की छोटी भुजा)। क्षेत्रफल प्राप्त करने के लिए इन दोनों भुजाओं का गुणा कीजिये। दुसरे शब्दों में:

क्षेत्रफल(A) = आधार(b) × ऊंचाई(H), या A = b × h संक्षिप्त में।

उदाहारण: यदि एक आयत के आधार की लम्बाई 10 सेमी है और उसकी ऊंचाई 5 सेमी है, तो आयत का क्षेत्रफल 10 × 5 (b × h) = 50 वर्ग सेमी.

ध्यान रखें कि किसी आकृति का क्षेत्रफल प्राप्त करने पर आप वर्ग इकाई (वर्ग सेमी, वर्ग मीटर , वर्ग फीट, इत्यादि) का उपयोग करेंगे।

3

वर्ग का क्षेत्रफल ज्ञात करते समय उसकी एक भुजा को उसी भुजा से गुणा कीजिये: वर्ग मूल रूप से एक विशेष आयत होता है, इसलिए आप वर्ग का क्षेत्रफल प्राप्त करने के लिए वही सूत्र उपयोग करते हैं। चूँकि वर्ग की सभी भुजाओं की लम्बाई समान होती है, आप सुगमता से एक भुजा को उसी भुजा से गुणन कर के क्षेत्रफल प्राप्त कर सकते हैं। यह वर्ग के आधार को उसकी ऊंचाई से गुणा करने के समान ही है, क्योंकि वर्ग में ऊंचाई और आधार की लम्बाई हमेशा समान ही होती है:[१]

क्षेत्रफल(A) = भुजा(s) × भुजा(s) या A = s2

उदाहारण : यदि किसी वर्ग की एक भुजा की लम्बाई 4 फीट है, (t = 4), तो इस वर्ग का क्षेत्रफल t2, या 4 x 4 = 16 वर्ग फीट होगा
