Find the general solution of the given system of odes. { dx/dt =2x 2y,dy/dt =x 3y}
Mumz [18]

The general solution of the given system of odes is

x(t)=c1c^{t} + c2e^{4t}

y(t)= c2e^{4t} -1/2 c1e^{t}

In arithmetic, a system of odes equations is a finite set of differential equations. Any such device may be either linear or non-linear. Also, such a machine can be both a machine of normal differential equations or a system of partial differential equations.

the compatibility conditions of an overdetermined system of odes equations may be succinctly stated in terms of differential forms (i.e., a shape to be specific, it needs to be closed). See integrability situations for differential systems for more.

It is an elaborately based poem praising or glorifying an event or character, describing nature intellectually as well as emotionally. A traditional ode is dependent on three essential parts: the strophe, the antistrophe, and the epode. Distinct forms together with the homostrophic ode and the abnormal ode also enter.

What is the surface area of a cone with a diameter of 28 cm. and height 22 cm in terms of Ï.
Svetlanka [38]

To find the surface area of a cone, use this formula.

pi (r) (r + [square root of h^2 plus r^2] )        substitute


h = height = 22                  r = radius = 28/2 = 14      [ ] = sq. root


pi (14) (14 + [ 22^2 + 14^2 ])                        solve exponents

pi (14) (14 + [484 + 196])                             add

pi (14) (14 + [680])                                       solve square root

pi (14) (14 + 2[170])                                     add

pi (14) (40.0768)                                         multiply

pi (561.075)  is about 561.1 rounded to nearest tenth


So the answer is C. 561.1pi cm^2

Re-write the quadratic function below in Standard Form<br> y=-3 (x - 2)² – 7
pav-90 [236]

Answer:

y=-3x^2+12x-19

Step-by-step explanation:

we know that

The quadratic equation in standard form is equal to

y=ax^{2} +bx+c

we have

y=-3(x-2)^{2}-7

This is a quadratic equation in vertex form

Convert to standard form

y=-3(x^2-4x+4)-7

Apply distributive property

y=-3x^2+12x-12-7

Combine like terms

y=-3x^2+12x-19 ----> quadratic equation in standard form

Please answer me .....
andrew11 [14]

Answer:

a. 2x -3

b. 7

Step-by-step explanation:

a. The expression that represents the difference is sales between the two sales will be:

9x - (7x + 3) = 9x - 7x - 3 = 2x - 3

b. What we do here is to simply substitute the value of 5 for x

mathematically, we have to substitute the value of 5 in the expression above

We have this as:

2(5) -3

= 10-3 = 7
