Answer:

E, 297.1

Step-by-step explanation:

First, find the area of the triangle using the formula a= (bh) / 2

Base x height would be 16 x 12, which is 192

192 / 2 is 96 sq meters

Then, find the area of the circle using the formula a= Pi (r^2)

If the diameter is 16, the radius would be 8 because you divide by 2

8^2 is 64, 64 times Pi is approximately 201.1

Finally, add the areas together, 96 + 201.1 is 297.1 or E

A field is a rectangle with a perimeter of 1240 feet. The length is 400 feet more than the width. Find the width and length of t

Wewaii [24]

Answer: The length is 510 and the width is 110.

Step-by-step explanation:

To find the area of a rectangle, you will have to add the 2 times the length plus 2 times the width because a rectangle have 4 sides. Two widths and two lengths.

You can now use the formula P= 2l + 2w

were P is the perimeter , l is the length, and w is the width.

the length is 400 more than the width, so we can represent that by the equation, l = w + 400

And now we know that the width is w.

So now we will input the perimeter, length, and into the formula to solve for w.

1240 = 2(w + 400) + 2w

1240 = 2w + 800 + 2w

1240 = 4w + 800

-800 -800

440 = 4w

w = 110

L= 110 + 400

L = 510

Check :

1240 = 2(510) + 2(110)

1240 = 1020 + 220

1240 = 1240

The company A produces products a, and the company B produces products b. It is known that 3 percent of companies that produce p

jeka94

Answer:

0.00183

Step-by-step explanation:

The two companies produce different products and the chance to go bankrupt will be different based on the product made. So, the probability of the company A and B to go bankrupt is independent.

To find the answer of this question, we just need to multiply the probability to go bankrupt of each company. The calculation will be:

P(A=bankrupt) * P(B=bankrupt)= 3% * 6.1% =0.183%= 0.00183

(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 $K(t)\neq 0$
