Answer:

<em>(D). 5 km²</em>

Step-by-step explanation:

QR² = 11² + 14² - 2(11)(14)cos77°

QR ≈ 15.739 km

P = 14 + 11 + 15.739 = 40.739 km

s = \frac{P}{2} ≈ 20.37 km

A_{PQR} = \sqrt{20.37(20.37-11)(20.37-14)(20.37-15.739)} ≈ <em>75 km²</em>

Question 1
fredd [130]

Hello!

The graphs of sine and cosine are waves. Therefore, choice A and B are wrong.

The graph of f(x) = cot(x) is an inverse of f(x) = tan(x), so therefore the graph of f(x) = cot(x) has the lines similar to the graph above, but it's flipped.

So therefore, the graph shown above is choice C, f(x) = tan x.

What is the correct equation ​
Andrej [43]

Answer: y = 0.4x

In fraction form, this is y = (2/5)x

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

Explanation:

For each row, divide the y over x values

  • Row One: y/x = 0.8/2 = 0.4
  • Row Two: y/x = 4/10 = 0.4
  • Row Three: y/x = 6/15 = 0.4
  • Row Four: y/x = 10/25 = 0.4

We end up with the same thing each time.

Since y/x = 0.4, this rearranges to y = 0.4x

Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4
