3 cards are drawn from a standard deck of 52 playing cards. How many different 3-card hands are possible if the drawing is done without replacement?

Answers

Answer 1
Answer:

Since you start with 52 cards, and are drawing 3 cards you multiply 52 * 51 * 50 then divide that product by 3 * 2 because it doesn’t matter what order the cards are drawn in. 52 * 51 * 50/ 3 * 2 = 22,100 different combinations of 3 cards

The image of a parabolic lens is traced onto a graph. The function f(x) = 1/4 (x+8)(x-4) represents the image. Atwhich points does the image cross the x-axis?

O (-8, 0) and (4,0)
(8,0) and (-4, 0)
O (2, 0) and (-1,0)
O (-2, 0) and (1, 0)

Answers

The image of the parabolic lens crosses the x axis at the points

(-8, 0) and (4, 0)

How to find the points where the image cross x axis

To find the points where the graph of the function crosses the x axis we need to find the values of x that make f(x) equal to zero

hence we have that

f(x) = 1/4 (x + 8) (x - 4)

0  = 1/4 (x + 8) (x - 4)

x + 8 = 0

x = -8

OR

x - 4 = 0

x = 4

hence we can say that the image of the parabolic lens crosses the x axis at the points (-8, 0) and (4, 0)

1. Line L passes through point (-1, 2) and (-3,-2) on a coordinate plane. LineM passes through the points (1.1) and (-1, W). For what value of W will make
line L and line M parallel.

Answers

Answer:

Slope of a line passing through (x_(1),y_(1)) and (x_(2) , y_(2)) is given by:

(y_(2)-y_(1) )/(x_(2)-x_(1))

Now,

Slope of line L, (m) = (-3-(-1))/(-2-2) = 0.5

Slope of line M, (n) = (-1-1)/(W-1) = (-2)/(W-1)

If the lines L and M are parallel to each other,

m = n

or, 0.5 = (-2)/(W-1)

or, 0.5 (W - 1) = -2

or, W - 1 = -4

or, W = -3

Therefore the required value of W is -3.
