|
Answer» Step-by-step EXPLANATION: ANSWER We have, y=
x−4 Slope = m= 3
TAN θ = 3
θ=60 o
This is the ANGLE made by the line with the x-axis. Therefore, the angle made by the line with the y-axis is 90−60=30 o |

Answer» Hello friends, today I am very happy because many DAYS of RESEARCH of maths, now I achieved and invented a new formula. That is, :: 0+2+4=There are three numbers of EVEN number. When we count there are three, so before there is two, So just multiply accordingly 2×3=6. 0+2+4+6= There are FOUR numbers, so before 4 there is three, So just multiply 4×3=12.. Simply, however when you get many even numbers in cereal then use this formula. And when you get odd numbers, then use Pythagoras theorem (1+3+5+7= there are four numbers, so 4²=16) HENCE we got. Hence you can try a question of Abinash's theorem....... 0+2+4+6+8+10+12+14=? Answer friends. So you can easily claculate: 1+2+3+4+5+.......+100=? (Use my method and Pythagoras theorem ie; 0+2+4+.......+50 and 1+3+5+7+......+49 And after that plus it even and odd numbers) Have a nice day... |

Answer» Step-by-step explanation: Answer: Rate at which volume of the BUBBLE is increasing = 72 π cm³/s Step-by-step explanation: Given: Radius of an air bubble is increasing at the rate of 2 CM/s To Find: The rate at which the volume of the bubble is increasing when the radius of the air bubble is 3 cm. Solution: Let the radius of the air bubble be R cm and volume be V. Here the air bubble is in the shape of a sphere. Volume of a sphere = 4/3 × π × r³ Now the rate of volume change with respect to time is given by, \sf \dfrac{dV}{dt} = \dfrac{d}{dt} (\dfrac{4}{3}\: \PI r^{3}) dt dV
= dt d
( 3 4
πr 3 ) Using chain rule, \sf \dfrac{dV}{dt} =\dfrac{d}{dr} (\dfrac{4}{3}\: \pi r^{3} ).\dfrac{dr}{dt} dt dV
= dr d
( 3 4
πr 3 ). dt dr
Differentiating, \sf \dfrac{dV}{dt} =\dfrac{4}{3}\: \pi \times 3r^{2} .\dfrac{dr}{dt} dt dV
= 3 4
π×3r 2 . dt dr
Now the rate of increase of radius of the air bubble is given as, \sf \dfrac{dr}{dt} =2\:cm/s dt dr
=2cm/s Also by given, the radius of the air bubble is 3 cm. Substitute the data, \sf \dfrac{dV}{dt} =\dfrac{4}{3}\: \pi \times 3\times 3^{2} \times 2 dt dV
= 3 4
π×3×3 2 ×2 Simplifying we get, \sf \dfrac{dV}{dt} =4\times \pi \times 9\times 2 dt dV
=4×π×9×2 ⇒ 72 π cm³/s Therefore the rate at which the volume of the air bubble is increasing is 72 π cm³/s. |

Answer» Answer: 7.6: The Method of Frobenius I Last updatedAug 13, 2020 7.5E: Regular SINGULAR Points Euler Equations (Exercises) 7.6E: The Method of Frobenius I (Exercises) picture_as_pdf Readability Donate trench-1995.jpg Contributed by William F. Trench Andrew G. Cowles Distinguished Professor Emeritus (Mathamatics) at Trinity University Sections 7.5-7.7 deal with three distinct cases satisfying the assumptions introduced in Section 7.4. In all three cases, (A) has at least ONE solution of the form y1=xr ∞ ∑ n=0 anxn, where r need not be an integer. The problem is that there are three possibilities - each requiring a different approach - for the form of a second solution y2 such that {y1,y2} is a fundamental pair of solutions of (A). In this section we begin to study series solutions of a homogeneous LINEAR second order differential equation with a regular singular point at x0=0, so it can be written as x2A(x)y″+xB(x)y′+C(x)y=0, where A, B, C are polynomials and A(0)≠0. We’ll see that Equation 7.6.1 always has at least one solution of the form y=xr ∞ ∑ n=0 anxn |
