If the mug was traced in the center of the paper, she could fold the paper in half vertically and horizontally to find the center point of the mug.

Step-by-step explanation:

Jeanne traced her coffee mug on her piece of paper and now she is trying to find the center of the circle.

Jeanne must cut the piece of the paper in the shape of a circle according to the coffee mug.

Now Jeanne has to fold the paper circle in such a way as to make a semi circle.

After making the first semi circle Jeanne has to make another fold to make one smaller semi circle.

Now open the paper and Jeanne will notice two straight line intersecting at a point.

This straights lines are called the diameters of the circle and the point is the center of the circle.

(10 pts) (a) (2 pts) What is the difference between an ordinary differential equation and an initial value problem? (b) (2 pts)
laiz [17]

Answer:

Step-by-step explanation:

(A) The difference between an ordinary differential equation and an initial value problem is that an initial value problem is a differential equation which has condition(s) for optimization, such as a given value of the function at some point in the domain.

(B) The difference between a particular solution and a general solution to an equation is that a particular solution is any specific figure that can satisfy the equation while a general solution is a statement that comprises all particular solutions of the equation.

(C) Example of a second order linear ODE:

M(t)Y"(t) + N(t)Y'(t) + O(t)Y(t) = K(t)

The equation will be homogeneous if K(t)=0 and heterogeneous if K(t)\neq 0

Example of a second order nonlinear ODE:

Y=-3K(Y){2}

(D) Example of a nonlinear fourth order ODE:

K^4(x) - \beta f [x, k(x)] = 0

(2-3a)(8+5a) please help me
IceJOKER [234]

Answer:

-15a² -14a+16

Step-by-step explanation:

<h2>(2-3a)(8+5a)</h2>

2×8=16

2×5a=10a

-3a×8=-24a

-3a×5a=-15a²

16+10a-24a-15a² = -15a² -14a+16

Quiz 2 Problem A big ship drops its anchor. The variable ll l l models the anchor's elevation (in meters) relative to the water'
alexandr1967 [171]

Answer:

Initial height of the anchor is 75 meters.          

Step-by-step explanation:

We are given the following in the question:

l(t)=-2.4t+75

where, I is the anchor's elevation in meter after t seconds dropped from the ship.

We have to find the initial height of anchor that is we have to put t = 0  in the equation.

Putting t = 0, we get,

l(0)=-2.4(0)+75 = 75

Thus, initial height of the anchor is 75 meters.
