Answer: 9 × 10^8

Step-by-step explanation:

Scientific notation is a when numbers that are too big or small are expressed in a convenient manner by writing them in decimal form.

Scientific notation is usually used by mathematicians, and engineers, to simplify arithmetic operations. It I written as : a × 10^n i.e a times 10 raise to the power of n.

900 million= 900,000,000

Note that a = 9 and n= 8

900 million= 900000000 = 9×10^8.

Find the general solution for the differential equation \displaystyle{\left.{d}{y}\right.}+{9}{x}\ {\left.{d}{x}\right.}={0}dy+9

densk [106]

Answer:

y= CC-4.5x^2

Step-by-step explanation:

To find the general solution to the differential equation

dy + 9x dx = 0, we employ the method of separating variable as follows:

Note: { will represent the integral sign here.

Separating the variables and integrating, we have

{dy = -{9x dx

y = -(9/2)(x^2) + CC,

where CC is the given constant of integration.

This can be rearranged/simplified to yield

y= CC-4.5x^2

Answer:

Step-by-step explanation:

Given that Steve invests in a circus production. The cost includes an overhead of $84,000, plus production costs of $2000 per performance. A sold-out performance brings in $8000.

Sales per performance =8000

Production cost per performance =2000

Contribution per performance = $8000-2000=6000$
