If p(x) = x^2 -2√2 x+1 then p2√2

Answer»

Answer:1

Step-by-step explanation:

In p (x) we put the required value of x

p (x) = x^2 - 2root2 x + 1

P (2root2) = 2root2^2 -2root2 ×2root2 +1

P (2root2) = 0 + 1 (cancelling like terms)

44) If a number is divided into three parts which are inthe ratio 1:1:2, then what percentage of the totalvalue is the sum of the equal parts?richt

Answer»

$\large{\underline{\bf{\purple{Given:-}}}}$

✦ Ratio of three PARTS = 1:1:2

$\large{\underline{\bf{\purple{To\:Find:-}}}}$

✦ percentage of total in the SUM of EQUAL parts .

$\huge{\underline{\bf{\red{Solution:-}}}}$

LET the 1st parts be 1 = x

third part 2 = 2X

sum of all parts = x + x +2x

Answer» To FIND the quadrant of a circle we will have to first determine the circumference of the circle which is 2πr. Here, the circumference being 44CM, 2πr=44. Therefore, radius of circle = r=44/2π =447/222= 7CM. (π=22/7) Now, AREA of circle = πr^2 = 22*(7^2)/7 = 154.06 cm². The area of the quadrant of a circle whose circumference in 44 cm is = 154.06 cm².

Find the area of a quadrant of a circle whose circumference is 44 cm

Answer»

To FIND the quadrant of a circle we will have to first determine the circumference of the circle which is 2πr.

Here, the circumference being 44CM, 2πr=44.

Therefore, radius of circle = r=44/2π =44*7/2*22= 7CM. (π=22/7)

Now, AREA of circle = πr^2 = 22*(7^2)/7 = 154.06 cm².

The area of the quadrant of a circle whose circumference in 44 cm is = 154.06 cm².

Find and correct the error in finding the length of CD. Justify your reasoning. show work please.

Answer»

$Here, two \:chords \:AB \: and \:CD ,\: when$

$produced, \: meet \:at \:a \:point \: F.$

$\therefore FB \times FA = FC \times FD$

$\implies ( FA + AB) \times FA = ( FD + DC )\times FD$

$\implies ( 3 + 5 )\times 3 = ( 4 + DC ) \times 4$

$\implies 8 \times 3 = ( 4 + DC ) \times 4$

$\implies \times {8 \times 3 }{4} = 4 + DC$

$\implies 4 + DC = 6$

$\implies DC = 6 - 4$

$\implies DC = 2$
