Figure ABCD is graphed on a coordinate plane.
Phoenix [80]
1. BC is 1+3=4 (units)

2. AD is 3+5= 8 (units)

3. Draw the altitude CH from point C, as shown in the figure.

4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.

5. CD^2=HD^2+CH^2

CD^2=2^2+4^2=4+16=20

CD= \sqrt{20}= \sqrt{4*5}= \sqrt{4} *  \sqrt{5}=2 \sqrt{5}= 4.47

6. AB=CD=4.47 because the trapezoid is isosceles.

7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)

How do I graph y-2=-(x+3)
Ira Lisetskai [31]
It is point slope
y-y1 = m(x-x1)
y1 = 2, m = -1, x1 = -3
Make it into slope intercept
Y = -1x + b
2 = 3 + b, b = -1
Y = -1x - 1

A teacher surveyed his class about how many played a sport and worked part-time at a job. The Venn diagram shows her results. If
Elanso [62]

Answer:

2/ 5

Step-by-step explanation:

From the venn diagram, find tbe probability ;

P(work | sport)

Recall :

P(A | B) = P(A n B) / P(B)

From the venn diagram :

P(work | sport) = P(work n sport) / P(sport)

P(work n sport ) = 4

P(sport) = 6 + 4 = 10

Therefore,

P(work | sport) = P(work n sport) / P(sport)

P(work | sport) = 4 / 10

P(work | sport) = 2/5
