A scale drawing of a soccer field is 6 inches long. The actual soccer field is 300 feet long. Which of the following represents

sveticcg [70]

Answer: IT IS BBBB

Step-by-step explanation:

In the figure attached, the complete question is shown.

Originally the scale is 1 inch: 12 yards, the width is 6 inches, that is, 6*12 = 72 yards, and the length is 9 yards, that is, 9*12 = 108 yards

If the scale is 1 inch: 36 yards, then 72 yards are:

1 inch / x inches = 36 yards / 72 yards

x = 72/36 = 2 inches

which represents the new width.

And 108 yards are:

1 inch / x inches = 36 yards / 108 yards

x = 108/36 = 3 inches

which represents the new length.

The junior and senior class officers are sponsoring a homecoming dance. The total cost for the facilities and catering is $45 pe

Answer:

Domain is (0,∞)

Range is (45, ∞)

Step-by-step explanation:

Let x represents the number of persons and f(x) represents the average cost per person,

∵ Fixed cost = $ 2500

Also, additional cost is $ 45 per person,

So, the total cost for x persons ( in dollars ) = fixed deposit + additional cost for x persons,

= 2500 + 45x

$\text{Average cost for x persons}=\frac{\text{Total cost}}{x}$

$\implies f(x)=\frac{2500+45x}{x}$

Which is a rational function,

∵ A rational function is defined for all real numbers except those for denominator = 0

Denominator of f(x) = x

So, f(x) is defined for all real numbers except x ≠ 0,

Now, the cost can not be negative,

⇒ x > 0

Hence, the domain for f(x) is (0, ∞)

Again,

$f(x)=45+\frac{2500}{x}$

If $x\rightarrow \infty$

$f(x)\rightarrow 45$

So, 45 < f(x) < ∞

i.e., range of f(x) is (45, ∞)
