Pls help in a middle of an exam

Mathematics
1 answer:
KIM [24]2 years ago
3 0

Answer:

\frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}

Step-by-step explanation:

\frac{2x}{4x^2-9} + \frac{3}{2x^2+x-3} can be simplified to:
\frac{2x}{(2x-3)(2x+3)}+\frac{3}{(2x+3)(x-1)}

Make them have common denominators so:
\frac{(2x)(x-1) +3(2x-3)}{(2x-3)(2x+3)(x-1)}

Simplify:
\frac{2x^2-2x+6x-9}{(2x-3)(2x+3)(x-1)} = \frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}

I don't think you can simplify that fraction further so that's the answer.

What can a firm do to increase productivity in the short run once its marginal product is zero?
Tems11 [23]

Answer:

  Decrease the quantity of the input

Step-by-step explanation:

The general assumption is that productivity is a curve that is concave downward, Hence marginal product is decreasing until it reaches zero. The way to increase it is to reduce the input quantity to a value below the point where the curve reaches zero marginal product.

Please help! what equation best models this data?
kolezko [41]

Answer:

P = 309.35 + 2.31t

Step-by-step explanation:

The relation between the population of the USA and the time in years after 2010 will be linear as the increase in population is constant for every year since 2010 which is  2.31 million.

So, we can model the population P in million as a function of time(t) in years since 2010 as

P = 309.35 + 2.31t  ....... (1)

Now, for t = 0 i.e. in the year 2010, the population will be obtained from equation (1) to be 309.35 million.

Please help me Find a, b, and c
zlopas [31]

Answer:

It is A.

Step-by-step explanation:

To solve for b, use the 45-45-90 triangle theorem, in which each of the legs is x, so the legs would be 8. The hypotenuse would therefore be 8√2.

So without further solving the answer is A, since it's the only one with 8√2.

However, I will still solve for A and C. Using the 30-60-90 theorem, we have the sides as x, x√3, and 2x. The second longest side is b. Using this, we find a = 4√6 and c to be 4√2
