Answer:

see below

Step-by-step explanation:

1. y = mx+b where m is the slope

The first slope is -1/3

The second slope is 3

m1 = m2 means they are parallel False

m1*m2 = -1 means they are perpendicular

-1/3 *3 = -1 True

2. Squares and rhombi have all 4 sides with the same length. Squares however, have 4 angles that must equal 90 degrees. Squares are a special form of rhombi

3. To find the slope

m = (y2-y1)/(x2-x1)

= (2-11)/(-5-0)

=-9/-5

= 9/5

The distance is found by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

= sqrt( (-5-0)^2 + (2-11)^2)

= sqrt( 5^2 + (-9)^2)

= sqrt( 25+81)

= sqrt( 106)

Answer:

See below

Step-by-step explanation:

y = -1/3x + 2

y = 3x - 5

Slopes are -1/3 and 3, they are opposite-reciprocal, it means the lines are perpendicular

2. Difference between squares and rhombus:

The sides of a square are perpendicular to each other whereas the sides of a rhombus are not perpendicular to each other.
All the angles of a square are equal whereas only the opposite angles of a square are equal.
The two diagonals of a square are always equal in length while the two diagonals of a rhombus are unequal

3. points A(0,11) and B(-5,2)

Slope:

m= (y2-y1)/(x2-x1)= (2-11)/(-5-0)= -11/-5= 11/5

Distance between points:

√(x2-x1)²+(y2-y1)²= √ 25+121= √146 ≈ 12

Eduardwww [97]

(a) $^{6}C_1 * ^{6}C_1 = 36$ different possibilities
(b) $P(even die 1): \frac{1}{2}$
$P(even die 2): \frac{1}{2}$

So, there is a 1 in 4 chance that both dice will show an even.

Answer:

$5P3*6C4=60*15=900$

Step-by-step explanation:

$5P3$ refers to the permutations of 5 items taken 3 at a time. To evaluate this, we use factorials as follows;

$5P3=\frac{5!}{(5-3)!}$

The factorial of an integer n is evaluated as;

$n!=n*(n-1)*(n-2)*(n-3).......3*2*1$

Using this concept, the above expression can now be simplified as follows;

$5P3=\frac{5!}{2!}=\frac{5*4*3*2!}{2!}=5*4*3=60$

Therefore, the permutations of 5 items taken 3 at a time is 60.

The next expression, $6C4$ refers to the combinations of 6 items taken 4 at a time. The simplification utilizes similar concepts of permutations since we shall be involving factorials;

$6C4=\frac{6!}{4!(6-4)!}=\frac{6!}{4!*2!}=\frac{6*5*4!}{4!*2*1}=\frac{6*5}{2*1}=15$

Therefore, the combinations of 6 items taken 4 at a time is 15.

The final step is to evaluate the product;

$5P3*6C4=60*15=900$
