Answer: 1106.13 (2 decimal places)

Step-by-step explanation:

To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.

The formula for the area of a circle is πr^2 (pi x radius squared).

So when you put the numbers in the formula the area is πx11^2=380.1327111

Then to work out the area of the rectangle you would do base x height.

The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.

To find the area of the rectangle you do 22x33=726

So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.

726+380.1327111=1106.13 (2 decimal places).

What is the median of this set 14, 18, 31, 34, 44, 50

hodyreva [135]

Because there's an even number of values in this set, there is two middle values rather than one (31 and 34). To find the median we need to add them together and divide the sum by 2 (31 + 34 = 65, 65/2= 32.5) Our final answer is 32.5.

Answer:

<u>44 </u>students will ride on each bus.

Step-by-step explanation:

Given:

Mr. Shipley is in charge of a school trip.

317 students will go on the trip.

The school had seven buses and one van.

If the van can haul nine students.

Now, to find the number of students who will ride on each bus.

Total students who will go on trip = 317.

So, we deduct the nine students of van from total students.

$317-9=308.$

Thus, there are 308 students remaining for riding on the seven buses.

Now, to get the number of students that will be riding on each bus we divide 308 remaining students by number of buses:

$308\div 7$

$=44.$

Therefore, 44 students will ride on each bus.

Answer:

As x → -∞, f(x) → 0.5; as x → ∞, f(x) → 0.5

Step-by-step explanation:

Given function:

$f(x)=\dfrac{4x-7}{8x+8}$

<u>Asymptote</u>: a line that the curve gets infinitely close to, but never touches.

As the degrees of the numerator and denominator of the given function are equal, there is a horizontal asymptote at $y=\dfrac{a}{b}$ (where a is the leading coefficient of the numerator, and b is the leading coefficient of the denominator). This is the end behavior.

$\textsf{Horizontal asymptote}:y=\dfrac{4}{8}=\dfrac{1}{2}$

This is because as $x \rightarrow \infty$ the -7 of the numerator and the +8 of the denominator become negligible. Therefore, we are left with:

$f(x) \rightarrow \dfrac{4x}{8x}$

Therefore:

$\textsf{As }\:x \rightarrow - \infty, f(x) \rightarrow 0.5$

$\textsf{As }\:x \rightarrow \infty, f(x) \rightarrow 0.5$
