Answer: the slope = -2

Step-by-step explanation: Look at how x and y are changing from point to point. Judging by the graph, x is going over in a positive direction by 3 and y is going down by a negative 6. The slope is written as the change in y/the change in x, so if we insert the changes it is written as: -6/3. If we simplify this, it becomes: -2

Slope = change in y over change in x

A. Slope = (9- -3)/(5-2) = 12/3 = 4

Slope = 4

B. (-13 -11)/(8- -4) = -24/12 = -2

Slope = -2

A building meets the ground at a right angle. The top of a 10-foot ladder is placed against the bottom edge of a window in the b

Burka [1]

Answer:

8 ft

Step-by-step explanation:

Use pythagorean theorem. $a^{2}+b^{2}=c^{2}$ . Put 10 and 6 into the equation as b and c.

$a^{2}+6^{2}=10^{2}$

$a^{2} =100-36\\a^{2}=64\\a=8$

Therefore, the answer is 8ft.

A diagram is attached. Sorry it's kinda messy.

Eight people are entered in a race. If there are no ties, in how many ways can the first three places come out? a.336 b.368 c.67

Luden [163]

The first thing to do is to calculate how many ways you can choose 3 people from a set of eight. In order to do this, we need to use the attached formula.
(The letter 'n' stands for the entire set and 'r' stands for the number of objects we wish to choose.)
So we wish to choose 3 people ('r') form a set of 8 ('n')
combinations = n! / r! * (n - r)!
combinations = 8 ! / (3! * 5!)
combinations = 8 * 7 * 6 * 5! / (3!) * (5!)
combinations = 8 * 7 * 6 / 3 * 2
combinations = 56

Now of those 56 combinations, the 3 people can finish in 6 different ways.
For example, persons A, B and C could finish
ABC or ACB or BAC or BCA or CAB or CBA

So to get the TOTAL combinations we multiply 56 * 6 which equals
336 so the answer is (a)
