Can you give a step by step explanation for this problem?

Rus_ich [418]

Answer:

choose the first

Step-by-step explanation:

When h=0, T is the highest (because the temperature is highest at noon)

And knowing that the temperature difference in the world cannot exceed 60 degrees in a day, only the first choice is common sense.

Pie

Answer:

$\frac{12}{27}$ Simplified version

Step-by-step explanation:

$(\frac{4}{5} + \frac{1}{3})$ × $\frac{5}{9}$

The first step would be to add together what is in the parenthesis. Make sure that both fractions have the same denominator. In this problem they don't, so we have to find the least common number that they both have. The number here would be 15. 5 × 3 = 15 and vise versa.

$((\frac{4}{5} x \frac{3}{3}) + (\frac{1}{3} x \frac{5}{5}))$ × $\frac{5}{9}$

$(\frac{12}{15} + \frac{5}{15})$ × $\frac{5}{9}$

$(\frac{17}{15}$ × $\frac{5}{9}$ Multiply straight across (denominators do NOT need to be the same)

$\frac{85}{135} = \frac{12}{27}$

Answer:

10,000 pPhones.

Step-by-step explanation:

The cost to manufacture x pPhones is given by the cost function:

$C(x)=-25x^2+49000x+21390$

And the revenue for selling x pPhones is given by the revenue function:

$R(x)=-29x^2+129000x$

We want to determine the number of pPhones the Pear Company should sell to maximize profits.

First, we can find the profit function. Profit is given by:

$P(x)=R(x)-C(x)$

Therefore:

$P(x)=(-29x^2+129000x)-(-25x^2+49000x+21390)$

Simplify:

$P(x)=(-29x^2+129000x)+(25x^2-49000x-21390)$

Add. So, our profit function is:

$P(x)=-4x^2+80000x-21390$

Note that our profit function is a quadratic. The maximum point of a quadratic is always its vertex. So, we can find the vertex of the profit function.

The coordinate of the vertex is given by:

$\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)$

In this case, a = -4, b = 80000, and c = - 21390.

Therefore, the point at which profit is maximized is:

$\displaystyle x=-\frac{80000}{2(-4)}=-\frac{80000}{-8}=10000$

Therefore, in order to maximize profits, the Pear Company should sell exactly 10,000 phones.

Notes:

And the maximum profit will be:

$P(10000)=-4(10000)^2+80000(10000)-21390=\$399,978,610$
