Answer: h(x) = -1200x^2 + 1950x + 4950

=======================================

Work Shown:

f(x) = revenue from the north

f(x) = -750x^2 + 1500x + 2250

g(x) = revenue from the south

g(x) = -450x^2 + 450x + 2700

h(x) = total revenue, ie add the two revenues

h(x) = f(x) + g(x)

h(x) = (-750x^2+1500x+2250)+(-450x^2+450x+2700)

h(x) = -1200x^2 + 1950x + 4950

. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.

Alekssandra [29.7K]

Answer: $3^{\circ}C$

Step-by-step explanation:

Given

The temperature on Monday was $-5^{\circ}C$

By Tuesday, it becomes $-2^{\circ}C$

Change in temperature is the difference between the two temperatures.

$\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C$

Therefore, the change in temperature is $3^{\circ}C$ .

Two parallel lines are _____ coplanar.

dimulka [17.4K]

Answer:

1. always

2. sometimes

Step-by-step explanation:

Two lines are coplanar if they lie in the same plane or in parallel planes. There is ALWAYS a plane which contains two parallel lines (see first attached image for details).

Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes $\alpha$ and $\beta$ are parallel. Consider pair of lines $a$ and $a_1$ - they are parallel, but if you consider the pair of lines $a$ and $b_1$ , you can see they are not parallel.
