32. In the given figure, OP is equal to the diameter of a circle with centre O and PA and PB are tangents.Prove that ABP is an equilateral triangle.APOoQB |
|
Answer» PA and PB are the tangents to the circle. ∴ OA⊥PA ⇒ ∠OAP=90° In ΔOPA, sin∠OPA= OP OA
= 2r r
[Given OP is the diameter of the circle] ⇒ sin∠OPA= 2 1
=sin30⁰ ⇒ ∠OPA=30° Similarly, it can be proved that ∠OPB=30°. Now, ∠APB=∠OPA+∠OPB=30°+30°=60° In ΔPAB, PA=PB [lengths of tangents drawn from an external point to a circle are EQUAL] ⇒∠PAB=∠PBA....(1) [Equal sides have equal angles opposite to them] ∠PAB+∠PBA+∠APB=180° [Angle sum property] ⇒∠PAB+∠PAB=180°–60°=120° [Using (1)] ⇒2∠PAB=120° ⇒∠PAB=60° .(2) From (1) and (2) ∠PAB=∠PBA=∠APB=60° ∴ ΔPAB is an EQUILATERAL triangle. helpful to you |

4√3x²+5x-2√3find the zeros of the following quadratic polynomials and verify the realtion between the zeros and the co-efficients |
|
Answer» Answer: The given polynomial f(x) = 4√3 x^2 +5x - 2√3 = 4√3 x^2 + 8x - 3x - 2√3 = 4X(√3 x +2) - √3 (√3 x +2) = (√3x+2)(4x-√3) HENCE the zeroes are -2/√3 and √3/4 SUM of the roots = -2/√3 + √3/4 = -2√3/3 + √3/4 = (-8√3+3√3)/12 = -5√3/12 Sum of the roots = -b/a = -5/4√3 = -5√3/12 Hence sum of the roots =-b/a. Product of the roots = (-2/√3)(√3/4) = -1/2. Product of the roots = c/a = -2√3/4√3 = -1/2. So product of the roots = c/a. Thus, the RELATIONSHIP between the roots and coefficients is verified. |

Answer» Question:-➢ The radius of a circle is 1 cm. What is its area?
Solution:-━━━━━━━━━━━━━━━━━━━━━━━━━━ ࿊ Here, the question has given us the radius of the circle that is 1 cm respectively. Now, the question has asked us to find out the area of the circle. So, to find the area of the circle we need to APLY the formula of area of circle and we will GET the answer. ANSWER:-◈ The area of the circle is 3.14 cm². Correct option is B. GIVEN:-➔ Radius of the circle = 1 cm TO FIND:-➙ Area of the circle = ? FORMULA:-➲ Area of circle = πr² Where,
SOLVING BY APPLYING THE FORMULA:-➔ Radius of the circle = 1 cm ➲ Area of circle = πr² ⇝ Area = 3.14 × 1 × 1 ⇝ Area = 3.14 × 1 ⇝ Area = 3.14 cm² Thus, we GOT the answer. Area of the circle is 3.14 cm². As, the value of π is 22/7 or 3.14 here the 2nd option that is π cm² is correct because the answer is the value of π. So, the correct answer is B [π cm²]. ━━━━━━━━━━━━━━━━━━━━━━━━━━ |

(a) 4a + 22b, (b) -28a + 30b, (c) -4a + 22b, (d) 28a + 30b. Solution: 12a + 26b -4b – 16a. = 12a – 16a + 26b – 4b. = -4a + 22b. Answer: (c) 4. Simplify: (4 – 5) – (13 – 18 + 2). (a) -1, (b) –2, (c) 1, (d) 2. Solution: (4 – 5) – (13 – 18 + 2). = -1-(13+2-18). = -1-(15-18). = -1-(-3). = -1+3. = 2. Answer: (d) 5. What is |-26|? (a) -26, (b) 26, (c) 0, (d) 1 Solution: |-26| = 26. Answer: (b)
6. Multiply: (X – 4)(x + 5) (a) x2 + 5x - 20, (b) x2 - 4x - 20, (c) x2 - x - 20, (d) x2 + x - 20. Solution: (x – 4)(x + 5). = x(x + 5) -4(x + 5). = x2 + 5x – 4x – 20. = x2 + x - 20. Answer: (d) 7. Factor: 5x2 – 15x – 20. (a) 5(x-4)(x+1), (b) -2(x-4)(x+5), (c) -5(x+4)(x-1), (d) 5(x+4)(x+1). Solution: 5x2 – 15x – 20. = 5(x2 – 3x – 4). = 5(x2 – 4x + x – 4). = 5{x(x - 4) +1(x - 4)}. = 5(x-4)(x+1). Answer: (a). 8. Factor: 3y(x – 3) -2(x – 3). (a) (x – 3)(x – 3), (b) (x – 3)2, (c) (x – 3)(3y – 2), (d) 3y(x – 3). Solution: 3y(x – 3) -2(x – 3). = (x – 3)(3y – 2). Answer: (c). 9. Solve for x: 2x – y = (3/4)x + 6. (a) (y + 6)/5, (b) 4(y + 6)/5, (c) (y + 6), (d) 4(y - 6)/5. Solution: 2x – y = (3/4)x + 6. or, 2x - (3/4)x = y + 6. or, (8x -3x)/4 = y + 6. or, 5x/4 = y + 6. or, 5x = 4(y + 6). or, 5x = 4y + 24. or, x = (4y + 24)/5. Therefore, x = 4(y + 6)/5. Answer: (b). 10. Simplify:(4x2 - 2x) - (-5x2 - 8x). Solution: (4x2 - 2x) - (-5x2 - 8x) = 4x2 - 2x + 5x2 + 8x. = 4x2 + 5x2 - 2x + 8x. = 9x2 + 6x. = 3x(3x + 2). Answer: 3x(3x + 2)
11. Find the value of 3 + 2 • (8 – 3) (a) 25, (b) 13, (c) 17, (d) 24, (e) 15. Solution: 3 + 2 • (8 – 3) = 3 + 2 (5) = 3 + 2 × 5 = 3 + 10 = 13 Answer: (d) 12. Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each? Solution: 33/4 ÷ 4 pounds. = (4 × 3 + 3)/4 ÷ 4 pounds. = 15/4 ÷ 4 pounds. = 15/4 × 1/4 pounds. = 15/16 pounds. Now we know that, 1 POUND = 16 ounces. Therefore, 15/16 pounds = 15/16 × 16 ounces. = 15 ounces. Answer: 15 ounces. 13. Factor: 16w3 – u4w3 Solution: 16w3 – u4w3. = w3(16 – u4). = w3(42 - ((u2)2). = w3(4 + u2)(4 - u2). = w3(4 + u2)(22 - u2). = w3(4 + u2)(2 + u)(2 - u). Answer: w3(4 + u2)(2 + u)(2 - u). 14. Factor: 3x4y3 – 48y3. Solution: 3x4y3– 48y3. = 3y3(x4 – 16). = 3y3[(x2)2 - 42]. = 3y3(x2 + 4)(x2 - 4). = 3y3(x2 + 4)(x2 - 22). = 3y3(x2 + 4)(x + 2)(x -2). Answer: 3y3(x2 + 4)(x + 2)(x -2) |

This black hole pulls matter from blue star beside it. Credits: NASA/CXC/M.Weiss blackhole_2.jpg An artist's drawing SHOWS the CURRENT view of the Milky Way galaxy. Scientific evidence shows that in the middle of the Milky Way is a supermassive black hole. Credits: NASA/JPL-Caltech Black hole Sagittarius A This image of the center of the Milky Way galaxy was taken by the Chandra X-ray Observatory. Credits: NASA/CXC/MIT/F.K.

(Grades K-4) series.
A black hole is a place in space where gravity pulls so much that EVEN light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.How Big Are Black Holes? Black holes can be big or small. |
