5.	If the product of zeroes of the polynomial ax2-6x-6 is 4, find the value of a. Find the sum of the zeroes of the polynomial
Answer» Solution :- Given :- POLYNOMIAL = ax² - 6x - 6 Product of roots = 4 So as we know in a quadratic polynomial :- ax² + bx + c SUM of roots = -b/a Product of roots = c/a Now in our polynomial :- a = a b = -6 c = -6 ALSO product of roots = 4 So c/a = 4 → -6/a = 4 → 4a = -6 → a = -6/4 → a = -3/2 So $\Huge{\boxed{\sf{ a = \dfrac{-3}{2}}}}$

5.

If the product of zeroes of the polynomial ax2-6x-6 is 4, find the value of a. Find the sum of the zeroes of the polynomial

Answer»

Solution :-

Given :-

POLYNOMIAL = ax² - 6x - 6

Product of roots = 4

So as we know in a quadratic polynomial :-

ax² + bx + c

SUM of roots

= -b/a

Product of roots

= c/a

Now in our polynomial :-

a = a

b = -6

c = -6

ALSO product of roots = 4

So

c/a = 4

→ -6/a = 4

→ 4a = -6

→ a = -6/4

→ a = -3/2

So

$\Huge{\boxed{\sf{ a = \dfrac{-3}{2}}}}$

9.	What is the minimum value of 3 sinx+4 cosx ?
Answer» Answer: -5 Step-by-step explanation: For CALCULATING the maximum and minimum VALUE of a trigonometric equation we can USE this formula. Condition: The Equation must be of the form: a Cos x + b SIN x. Formula: Maximum Value = √ ( a² + b² ) Minimum Value = - √ ( a² + b² ) In our Case, it is of the form: ⇒ 3 Sin x + 4 Cos x Therefore, a = 4 and b = 3 ⇒ Minimum Value = - ( √ 3² + 4² ) ⇒ Minimum Value = - ( √ 25 ) = - ( 5 ) Hence the minimum value of the function is -5. Have a great day !!

What is the minimum value of 3 sinx+4 cosx ?

Answer»

Answer:

-5

Step-by-step explanation:

For CALCULATING the maximum and minimum VALUE of a trigonometric equation we can USE this formula.

Condition: The Equation must be of the form: a Cos x + b SIN x.

Formula:

Maximum Value = √ ( a² + b² )
Minimum Value = - √ ( a² + b² )

In our Case, it is of the form:

⇒ 3 Sin x + 4 Cos x

Therefore, a = 4 and b = 3

⇒ Minimum Value = - ( √ 3² + 4² )

⇒ Minimum Value = - ( √ 25 ) = - ( 5 )

Hence the minimum value of the function is -5.

Have a great day !!

Answer» ANSWER: डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या 100 है। Step-by-step explanation: दिया है : ईट की विमाएं, l = 22.5 सेमी, b = 10 सेमी, c = 7.5सेमी डिब्बे का संपूर्ण पृष्ठ क्षेत्रफल = 9.375 मी² ईट का संपूर्ण पृष्ठीय क्षेत्रफल = 2(lb + BH+ lh) = 2(22.5 ×10 + 10 ×7.5 + 22.5 ×7.5) = 2(225 + 75 + 168.75) = 2 × 468.75 = 937.5 सेमी² = (937.5) /100 × 100 मी² [1सेमी² = 1/10000 मी²] ईट का संपूर्ण पृष्ठीय क्षेत्रफल = (937.5) /100 × 100 मी² इस डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या = डिब्बे का संपूर्ण पृष्ठ क्षेत्रफल/ ईटों का संपूर्ण पृष्ठ क्षेत्रफल = 9.375/ (937.5/(100×100)) =( 9.375 ×100 ×100) / 937.5 = 93750/937.5 = 937500/ 9375 डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या = 100 अतः, डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या 100 है। आशा है कि यह उत्तर आपकी मदद करेगा। इस पाठ से संबंधित कुछ और प्रश्न : एक कमरे की लंबाई, चौड़ाई और ऊँचाई क्रमशः 5 m, 4m और 3 m हैं। 7.50 प्रति $m^2$ की दर से इस कमरे की दीवारों और छत पर सफेदी कराने का व्यय ज्ञात कीजिए। brainly.in/question/10330695 किसी आयताकार हॉल के फर्श का परिमाप 250 m है। यदि 10 प्रति $m2$ की दर से चारों दीवारों पर पेंट कराने की लागत रु 15000 है, तो इस हॉल की ऊँचाई ज्ञात कीजिए। [संकेत : चारों डिब्बों का क्षेत्रफल = पाश्र्व पृष्ठीय क्षेत्रफल ] brainly.in/question/10330762

किसी डिब्बे में भरा हुआ पेंट 9.375 के क्षेत्रफल पर पेंट करने के लिए पर्याप्त है। इस डिब्बे के पेट से 22.5 cm x 10 cm x7.5 cm विमाओं वाली कितनी ईंट पेंट की जा सकती हैं?

Answer»

ANSWER:

डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या 100 है।

Step-by-step explanation:

दिया है :

ईट की विमाएं, l = 22.5 सेमी, b = 10 सेमी, c = 7.5सेमी

डिब्बे का संपूर्ण पृष्ठ क्षेत्रफल = 9.375 मी²

ईट का संपूर्ण पृष्ठीय क्षेत्रफल = 2(lb + BH+ lh)

= 2(22.5 ×10 + 10 ×7.5 + 22.5 ×7.5)

= 2(225 + 75 + 168.75)

= 2 × 468.75

= 937.5 सेमी²

= (937.5) /100 × 100 मी²

[1सेमी² = 1/10000 मी²]

ईट का संपूर्ण पृष्ठीय क्षेत्रफल = (937.5) /100 × 100 मी²

इस डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या = डिब्बे का संपूर्ण पृष्ठ क्षेत्रफल/ ईटों का संपूर्ण पृष्ठ क्षेत्रफल

= 9.375/ (937.5/(100×100))

=( 9.375 ×100 ×100) / 937.5

= 93750/937.5

= 937500/ 9375

डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या = 100

अतः, डिब्बे के पेंट से पेंट की जाने वाली ईटों की संख्या 100 है।

आशा है कि यह उत्तर आपकी मदद करेगा।

इस पाठ से संबंधित कुछ और प्रश्न :

एक कमरे की लंबाई, चौड़ाई और ऊँचाई क्रमशः 5 m, 4m और 3 m हैं। 7.50 प्रति $m^2$ की दर से इस कमरे की दीवारों और छत पर सफेदी कराने का व्यय ज्ञात कीजिए।
