Answer:

The area of the triangle is 13.5 square units

Step-by-step explanation:

The easiest way to find the area of of a triangle is to find the area of rectangle surrounding it, and divide by two.

In this case, we can use the bottom line and the distance from that to the top point as the side lengths of our "rectangle"

The bottom line has a length of 9, and the distance from that line to the top point is 3. We can say then that the area of the triangle is half of three times nine:

3 × 9 ÷ 2 = 3 × 4.5 = 13.5

So the total area of the triangle is 13.5 square units

P = 0.52

(b) (0.5)(0.6) = 0.3

P = 0.3 / 0.52

Q10. Consider the following algorithm:

maw [93]

Answer:

61,940

Step-by-step explanation:

For a recursive sequence of reasonable length, it is convenient to use a suitable calculator for figuring the terms of it. Since each term not only depends on previous terms, but also depends on the term number, it works well to use a spreadsheet for doing the calculations. The formula is easily entered and replicated for as many terms as may be required.

The result of executing the given algorithm is shown in the attachment. (We have assumed that g_1 means g[-1], and that g_2 means g[-2]. These are the starting values required to compute g[0] when k=0.

That calculation looks like ...

g[0] = (0 -1)×g[-1] +g[-2} = (-1)(9) +5 = -4

The attachment shows the last term (for k=8) is 61,940.
