How do you convert joules to kJ

jek_recluse [69]

Answer:

Divide by 1000.

Step-by-step explanation:

For example, 1 joule is 0.001 kilo joule.

1 divided by 1000 is 0.001.

If there were 30 joules, there would be 0.032 kilo joules.

I'm not sure how to figure this out

Answer:

10°, 80°

Step-by-step explanation:

Setup

Let x and y represent the measures of the two acute angles in the right triangle.

From your knowledge of right triangles, you know the two acute angles are complementary:

x + y = 90

The problem statement gives you another relation:

x = 2(y + 30) . . . . twice the sum ...

__

Solution

The second equation gives you an expression for x that can be substituted into the first equation.

(2(y +30)) + y = 90

3y +60 = 90 . . . . . . . . collect terms

3y = 30 . . . . . . . . . subtract 60

y = 10 . . . . . . . . divide by 3

x = 2(y +30) = 2(40) = 80

The two angles are 10° and 80°.

For a certain company, the cost function for producing x items is C(x)=40x+150 and the revenue function for selling x items is r

Nastasia [14]

No, we are unable to produce an endless amount in a given space. because the function is at its highest point when x is equal to 70, and its highest point of output is 2300.

We are unable to produce zero items in one day.

Maximum available output = 2300

The graph of the function is quadratic (parabolic), and the point at which it reaches its highest value, denoted by the vertex x = 70,

<h3>What is the maximum capacity of a company?</h3>

Generally, The greatest level of production that a firm is able to maintain in order to provide its goods or services is referred to as its capacity. Capacity may refer to a manufacturing process, the distribution of human resources, technological thresholds, or any one of a number of other related ideas, depending on the sort of company being discussed.

In conclusion, No, we are unable to produce an endless amount in a given space. because the function is at its highest point when x is equal to 70, and its highest point of output is 2300.

We are unable to produce zero items in one day.

Maximum available output = 2300

The graph of the function is quadratic (parabolic), and the point at which it reaches its highest value, denoted by the vertex x = 70,
