Answer» Step-by-step explanation: let the point at right angle be O in triangle AOB ....AB= 13 ( by Pythagoras theorem) area of triangle AOB= 1/2*Base*height = 30 sq cm Now..in triangle ABC , AB (a)= 13..BC(b)= 14 & CD (c)=15 Semi-perimeter(s)= a+ b + c by 2 =21 cm By herons formula, area of ABC = √ s(s-a)(s-b)(s-c) = √21 (21 -13) (21 -14 )(21- 15) =√21*8*7*6 =√ 7056 cm ^ 2 = 84 cm^ 2 therefore the area of SHADED region = AR (ABC )-ar (AOB) =84-30 = 54 cm ^2 plzz mark me as brainlest.. |

Find a quadratic polynomialwhose sum and product of itszeroes are -4 and 1respectively." |
Answer» ANSWER :- x² + 4x + 1<P>Solution :-Given :- ⇒ Sum of zeroes, ɑ + β = -4 ⇒ Product of zeroes, ɑβ = 1 To Find :-⇒ Polynomial p(x) satisfying the above condition. Solution :-We KNOW, A standard quadratic polynomial is of the form x² - (sum of zeroes)x + (product of zeroes) ⇒ p(x) = x² - (sum of zeroes)x + (product of zeroes) ⇒ p(x) = x² - (-4)x + (1) ⇒ p(x) = x² + 4x + 1 Hence, The REQUIRED polynomial is x² + 4x + 1 EXTRA INFORMATION :- ◉ The standard form of quadratic polynomial is ax² + bx + c, where a & b are integers and a ≠ 0, c is a constant. ◉ A quadratic polynomial can also be thought as a quadratic equation, So:
⇒ D = 0 Zeroes are equal and real. ⇒ D > 0 Zeroes are real and distinct. ⇒ D < 0 Zeroes are imaginary.
Zeroes and its Relationship with the Coefficient :-
Given a quadratic polynomial, p(x) = ax² + bx + c Then, the sum of zeroes = -b/a
Given a quadratic polynomial, p(x) = ax² + bx + c Then, the product of zeroes = c/a A Quick Tip: If you are given sum of zeroes and product of zeroes then you can find the two zeroes by using the following algorithm:-
⇒ (ɑ - β)² = (ɑ + β)² - 4ɑβ

A and B together can complete a work in3 days. They start together but after 2 days, Bleft the work. If the work is completed aftertwo more days, B alone could do the work in |
|
Answer» Answer: 1st Method: (A+B)'s one DAY's work = 1/3 PART; (A+B) WORKS 2 days together = 2/3 part; Remaining work = 1-(2/3) = 1/3 part; 1/3 part of work is completed by A in two days; Hence, one day's work of A = 1/6; Then, one day's work of B = 1/3-1/6=1/6; So, B alone can COMPLETE the whole work in 6 days. 2nd method: (A+B)'s one day's % work = 100/3 = 33.3% Work completed in 2 days = 66.6% Remaining work = 33.4%; One day's % work of A = 33.4/2 = 16.7%; One day's work of B = 33.3 - 16.7 = 16.7%; B alone can complete the work in, = 100/16.7 = 6 days. |

Why are 1\4 and -1 zeroes of the polynomials p(x)=4x^+3x-1? |
|
Answer» Answer: Step-by-step explanation: First of all the symbols like p(x), G(x), F(x) means the given polynomial have variable x i.e the value of X will change but all other value are constant NOW, zero of any polynomial means that value of variable on which whole polynomial becomes zero means p(x) will be zero Here, if we consider the value of X as 1/4 then P(1/4)= 4×(1/4)^2 +3×1/4 - 1 or 4×(1/16) + 3/4 - 1 or 1/4 + 3/4 - 1=0 Here p(x) =0 so it is zero of the polynomial ON the other hand if we consider the value of X as - 1 then P(-1)=4×(-1)^2 + 3(-1) - 1 Or 4×1 + - 3 - 1 =0 We observed here that on putting the value of X as 1/4 and - 1 who expression turns 0 so these are 0 of the given polynomial |
