2.	If x² + 4ax + 3 = 0 and 2x² + 3ax - 9 = 0 have a common root , then the value of "a" is what ??
Answer» Let the common root be m. Put in the equations; m² + 4am + 3 = 0 --------------(1) 2m² + 3am - 9 = 0 --------------(2) multiply equation (1) by 2 2m² + 8am + 6 = 0 -------------(3) (NOTE that equation 1 and 3 are the same) subtract (2) from (3); you will get (2m² + 8am + 6) - (2m² + 3am - 9) = 0 ⇒ 5am + 15 = 0 ⇒ 5am = -15 ⇒ m = $- \frac{15}{5a} =- \frac{3}{a}$ from equation (1), $(- \frac{3}{a})^{2} + 4a(- \frac{3}{a})+3=0\\ \\ \frac{9}{a^2} - 12+3=0\\ \\ \frac{9}{a^2} -9=0\\ \\\frac{9}{a^2}=9\\ \\a^2= \frac{9}{9}=1\\ \\a=+1\ or\ -1$ So values of a are +1 and -1.

3.	on sunday the seahawks had a net yardage of (-26 1/2) yards on a series of plays.the team needs a net yardage of 10 yards to get a first down.how many yards do they have to get on their next play to get a first down?
Answer» Net yardage = $-26 \frac{1}{2} = -\frac{53}{2}$ Yardage required for first down = 10 Yardage needed in NEXT MATCH = $10-(- \frac{53}{2} )=10+\frac{53}{2}= \frac{20+53}{2} = \frac{73}{2}=\boxed{36 \frac{1}{2} }$ $36 \frac{1}{2}$ So they have to get yardage on their next PLAY to get a first down.

Answer» 1. Given, DIAMETER and HEIGHT of a cylinder are 42cm and 10cm. then r = 42/2 = 21 Then it's volume = πr²h = 22/7 × 21× 21× 10 = 13,860 cm³ 2. volume of cylinder = πr²h = 3960 πr²h = 3960 => r²h = 3960 × 7/22 r²h = 1260 ---------- 1 csa of cylinder = 2πrh = 1320 2πrh = 1320 => rh = 1320 × 7/22×2 rh = 210 h = 210/r ---------------------2 by substituting in 1 we get r² × 210/r = 1260 r = 1260/210 r = 6 cm then by substituting it in 2 we get h = 210/6 h = 35 cm therefore radius(r) = 6 cm and height(h) = 35 cm

22.	In the given figure , if AOD = 135 then BOC is equal to what a)52.5b)45c)62.5d)24
Answer» Mark the angles a, x and y. Then find the other angles, because we have right ANGLE triangles. Also we have identical triangles, as the sides are tangents from A , B C and D on to the circle. So the LENGTHS of tangent segments on to the circle are equal. Thus the angles inside the TWO adjacent triangles are equal. Sum of all angles at the center = 360 deg 135-a + 135-a + a + a + 2 x + 2 y = 360 deg 2x + 2y = 90 deg x + y = 45 deg = angle BOC.

26.	George is reading a novel which has 303 pages. how many times does the digit 3 get printed in the page numbers? how many pages are there which has only one 3 present in the page number?
Answer» Case 1: numbers with 3 are like 3,13,23,......,303 they are in AP with a=3, d=10 let the total number of pages with the DIGIT 3 be N. 303 = 3 + (n-1)10 ⇒ n-1 = 300/10 = 30 ⇒ n = 31 number of pages = 31 case 2: number like 30,31,...39; 130,131,...139; 230,231,...239 from 30 to 39 - there are 10 numbers from 130 to 139 - there are 10 numbers from 230 to 239 - there are 10 numbers total = 10+10+10 = 30 but we have already counted 33,133 and 233. so number of pages = 30-3 = 27 case 3: the number 300,301 and 302. (303 has already been counted) so numbers = 3 So total number of pages = 31+27+3 = 61 every number having three has only one three except 33,133,233 and 303. number of pages with 2 threes = 4 number of pages with only one three = 61 - 4 = 57 total number of PRINTING of 3 = 57×1 +4×2 = 57+8 = 65. So the digit 3 has been printed 65 times and number of pages with only one 3 present is 57.

Answer»

Given : The diameters of the internal and external surfaces of a hollow hemispherical shell are 6cm and 10cm . melted and RECAST into a solid cylinder of diameter 14cm

To find : Height of cylinder

Solution:

internal and external Diameter = 6cm & 10 cm

=> internal & external RADIUS = 3cm & 5 cm

Volume of hemisphere = (2/3)π(5³ - 3³) = 196π/3 cm³

Volume of solid cylinder = πr²h

diameter = 14 => radius = 7 cm h = height in cm

= π(7)²h = 49πh cm³

49πh = 196π/3

=> h = 4/3 cm = 1.33 cm

AB = Diameter = 28 cm

AQ = (1/4) AB = (1/4) 28 = 7 cm => radius = (7/2) cm

=> BQ = 28 - 7 = 21 cm => Radius = (21/2) cm

Area of shaded REGION = (1/2)π (7/2)² + (1/2)π (21/2)²

= (1/8) (22/7) * 7² + (1/8) (22/7) *21²

= 154/8 + 1386/8

=1540/8

= 192.5 cm²

29.	Determine the ratio in which the line 3x + 4y - 9 = 0 divides the line segment joining the points (1,3) and (2,7).
Answer» Let the line 3x + 4y - 9 = 0 DIVIDES the line segment joining the points (1,3) and (2,7) in the ratio k:1 then the coordinate of the POINT is $( \frac{2k+1}{k+1}, \frac{7k+3}{k+1})$ . Since this the INTERSECTION point, it also lies on the line 3x + 4y - 9 = 0.Thus $3(\frac{2k+1}{k+1}) + 4(\frac{7k+3}{k+1}) - 9 = 0\\ \\3(2k+1)+4(7k+3)-9(k+1)=0\\ \\6k+3+28k+12-9k-9=0\\ \\25k+6=0\\ \\25k=-6\\ \\k=- \frac{6}{25}$ Since k is negative, the line 3x + 4y - 9 = 0 divides the line segment joining the points (1,3) and (2,7) externally in the ratio $\boxed{6:25}$

Answer» If a POINT (X,y) lies on a line JOINING the points A(x₁,y₁) and B(x₂,y₂), the equation of the line is GIVEN by $\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}$ Point P(x,y) lies on the line joining the points A(a,0) and B(0,b). So $\frac{y-0}{x-a} = \frac{b-0}{0-a} \\ \\ \Rightarrow \frac{y}{x-a}=- \frac{b}{a} \\ \\ \Rightarrow ay=-b(x-a)\\ \\ \Rightarrow ay=-bx+ab\\ \\ \Rightarrow ay+bx=ab\\ \\divide\ both\ sides\ by\ ab\\ \\ \Rightarrow \frac{ay}{ab}+ \frac{bx}{ab} = \frac{ab}{ab}\\ \\ \Rightarrow \frac{y}{b}+ \frac{x}{a} =1\ (proved)$
