The 4th term of an A.P. is equal to 3 times of the first term and the 7th term exceeds the 3rd term by 1. Find the first term and common difference. |
|
Answer» GIVEN :- The 4th term of an A.P. is equal to 3 times of the first term and the 7th term EXCEEDS the 3rd term by 1. Solution :- Let first term is a and common difference is d . so, → 4th term = 3a → a + (4 - 1)d = 3a → a + 3D = 3a → 3d = 3a - a → 3d = 2a -------- Eqn.(1) and, → T(7) - T(3) = 1 → (a + 6d) - (a + 2d) = 1 → a - a + 6d - 2d = 1 → 4d = 1 → d = (1/4) PUTTING value of d in Eqn.(1) → 3 * (1/4) = 2a → 2a = 3/4 → a = (3/8) therefore, first term of given AP is (3/8) and common difference is (1/4) . Learn more :- EVALUATE the expression given by 83 - 81 + 87 - 85 +__________ + 395 - 393 + 399 - 397 If the nth term of an AP is (2n+5),the sum of first10 terms is |

If f(x) = ax +bx+c has no real zeros and a +b+c< 0then |
|
Answer» Answer: ANSWER The GRAPH of the function satisfying the GIVEN conditions is SHOWN in the above picture. We can observe that the graph doesn't touch the X-axis i.e. it doesn't have any real roots and the value of f(1)=a+b+C<0. Now substitue x=0. Then we can observe that f(0)=c<0 ∴ Option C is corrrect. |

If y=tan(x+y), then find dy/dx |
Answer» ANSWER:sec² ( X + y ) / ( 1 - sec² ( x + y ) Step-by-step explanation:GIVEN : y = tan ( x + y ) Diff. w.r.t. x : d y / d x = sec² ( x + y ) . ( x + y )' = > y' = sec² ( x + y ) . ( ( x )' + ( y )' ) = > y' = sec² ( x + y ) . ( 1 + y' ) = > y' = sec² ( x + y ) + y' ( sec² ( x + y ) ) = > y' - y' ( sec² ( x + y ) ) = sec² ( x + y ) = > y' ( 1 - sec² ( x + y ) ) = sec² ( x + y ) = > y' = sec² ( x + y ) / ( 1 - sec² ( x + y ) Therefore , d y / d x of given function y = tan ( x + y ) is sec² ( x + y ) / ( 1 - sec² ( x + y ) |
