4 0

We need to find the probability of being dealt the queen of diamonds when you are dealt one card from a standard 52-card deck.

A standard deck has four queens. And just one of them is a queen of diamonds.

Thus, 1 out of 52 cards is the queen of diamonds.

Therefore, the probability of being dealt the queen of diamonds is given by 1 divided by 52:

$\frac{1}{52}$

the perimeter of the rectangle below is 98 units. Find the length of CD. Write your answer without variables. cd=4x+3 cb=5x+1

zimovet [89]

$2(4x + 3) + 2(5x + 1) = 98 \\ 8x + 6 + 10x + 2 = 98 \\ 18x + 8 = 98 \\ 18x = 90 \\ x = 5$
Substitute x with 5,

CD =
$4x + 3 \\ = 4(5) + 3 \\ = 20 + 3 \\ = 23$
CD = 23 units

Hope this helps.

Derive the equation of the parabola with a focus at (6,2) and a directrix of y=1

nydimaria [60]

Distance from focus to vertex=distance from vertex to directix

from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)

for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix

vertex=(6,1.5)
ditance=0.5

(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5
